As streaming demand surges worldwide, providers face mounting pressure to deliver high-quality video without buffering, lag, or quality dips, no matter where the viewer is or what device they're using. That pressure is only growing as audiences consume content across mobile, desktop, smart TVs, and edge-connected devices.
Traditional content delivery networks (CDNs) were built to handle scale, but not prediction. They reacted to demand, but couldn’t anticipate it. That’s changing.
Today, predictive streaming and AI-powered smart caching are enabling a proactive, intelligent approach to content delivery. These technologies go beyond delivering content by forecasting what users will need and making sure it's there before it's even requested. For network engineers, platform teams, and content providers, this marks a major evolution in performance, reliability, and cost control.
What are predictive streaming and smart caching?
Predictive streaming is a technology that uses AI to anticipate what a viewer will watch next, so the content can be ready before it's requested. That might mean preloading the next episode in a series, caching popular highlights from a live event, or delivering region-specific content based on localized viewing trends.
Smart caching supports this by storing that predicted content on servers closer to the viewer, reducing delays and buffering. Together, they make streaming faster and smoother by preparing content in advance based on user behavior.
Unlike traditional caching, which relies on static popularity metrics or simple geolocation, predictive streaming is dynamic. It adapts in real time to what’s happening on the platform: user actions, traffic spikes, network conditions, and content trends. This results in:
- Faster playback with minimal buffering
- Reduced bandwidth and server load
- Higher quality of experience (QoE) scores across user segments
For example, during the 2024 UEFA European Championship, several broadcasters used predictive caching to preload high-traffic game segments and highlight reels based on past viewer drop-off points. This allowed for instant replay delivery in multiple languages without overloading central servers.
Why predictive streaming matters for viewers
Globally, viewers tend to binge-watch new streaming platform releases. For example, sci-fi-action drama Fallout got 25% of its annual US viewing minutes (2.9 billion minutes) in its first few days of release. The South Korean series Queen of Tears became Netflix's most-watched Korean drama of all time in 2024, amassing over 682.6 million hours viewed globally, with more than half of those watch hours occurring during its six-week broadcast run.
A predictive caching system can take advantage of this launch-day momentum by pre-positioning likely-to-be-watched episodes, trailers, or bonus content at the edge, customized by region, device, or time of day.
The result is a seamless, high-performance experience that anticipates user behavior and scales intelligently to meet it.
Benefits for streaming providers
Traditional CDNs often waste resources caching content that may never be viewed. Predictive caching focuses only on content that is likely to be accessed, leading to:
- Lower egress costs
- Reduced server load
- More efficient cache hit ratios
One of the core benefits of predictive streaming is latency reduction. By caching content at the edge before it’s requested, platforms avoid the delay caused by round-trips to origin servers. This is especially critical for:
- Live sports and events
- Interactive or real-time formats (e.g., polls, chats, synchronized streams)
- Edge environments with unreliable last-mile connectivity
For instance, during the 2024 Copa América, mobile viewers in remote areas of Argentina were able to stream matches without delay thanks to proactive edge caching based on geo-temporal viewing predictions.
How it works
At the core of predictive streaming is smart caching: the process of storing data closer to the end user before it’s explicitly requested. Here’s how it works:
- Data ingestion: The system gathers data on user behavior, device types, content popularity, and location-based trends.
- Behavior modeling: AI models identify patterns (e.g., binge-watching behaviors, peak-hour traffic, or regional content spikes).
- Pre-positioning: Based on predictions, the system caches video segments, trailers, or interactive assets to edge servers closest to where demand is expected.
- Real-time adaptation: As user behavior changes, the system continuously updates its caching strategy.
Use cases across streaming ecosystems
Smart caching and predictive delivery benefit nearly every vertical of streaming.
- Esports and gaming platforms: Live tournaments generate unpredictable traffic surges, especially when underdog teams advance. Predictive caching helps preload high-interest match content, post-game analysis, and multilingual commentary before traffic spikes hit. This helps provide global availability with minimal delay.
- Corporate webcasts and investor events: Virtual AGMs or earnings calls need to stream seamlessly to thousands of stakeholders, often under compliance pressure. Predictive systems can cache frequently accessed segments, like executive speeches or financial summaries, at regional nodes.
- Education platforms: In EdTech environments, predictive delivery ensures that recorded lectures, supplemental materials, and quizzes are ready for users based on their course progression. This reduces lag for remote learners on mobile connections.
- VOD platforms with regional licensing: Content availability differs across geographies. Predictive caching allows platforms to cache licensed material efficiently and avoid serving geo-blocked content by mistake, while also meeting local performance expectations.
- Government or emergency broadcasts: During public health updates or crisis communications, predictive streaming can support multi-language delivery, instant replay, and mobile-first optimization without overloading networks during peak alerts.
Looking forward: Personalization and platform governance
We predict that the next wave of predictive streaming will likely include innovations that help platforms scale faster while protecting performance and compliance:
- Viewer-personalized caching, where individual user profiles guide what’s cached locally (e.g., continuing series, genre preferences)
- Programmatic cache governance, giving DevOps and marketing teams finer control over how and when content is distributed
- Cross-platform intelligence, allowing syndicated content across services to benefit from shared predictions and joint caching strategies

Protecting networks at scale with AI security strategies
Network cyberattacks are no longer isolated incidents. They are a constant, relentless assault on network infrastructure, probing for vulnerabilities in routing, session handling, and authentication flows. With AI at their disposal, threat actors can move faster than ever, shifting tactics mid-attack to bypass static defenses.Legacy systems, designed for simpler threats, cannot keep pace. Modern network security demands a new approach, combining real-time visibility, automated response, AI-driven adaptation, and decentralized protection to secure critical infrastructure without sacrificing speed or availability.At Gcore, we believe security must move as fast as your network does. So, in this article, we explore how L3/L4 network security is evolving to meet new network security challenges and how AI strengthens defenses against today’s most advanced threats.Smarter threat detection across complex network layersModern threats blend into legitimate traffic, using encrypted command-and-control, slow drip API abuse, and DNS tunneling to evade detection. Attackers increasingly embed credential stuffing into regular login activity. Without deep flow analysis, these attempts bypass simple rate limits and avoid triggering alerts until major breaches occur.Effective network defense today means inspection at Layer 3 and Layer 4, looking at:Traffic flow metadata (NetFlow, sFlow)SSL/TLS handshake anomaliesDNS request irregularitiesUnexpected session persistence behaviorsGcore Edge Security applies real-time traffic inspection across multiple layers, correlating flows and behaviors across routers, load balancers, proxies, and cloud edges. Even slight anomalies in NetFlow exports or unexpected east-west traffic inside a VPC can trigger early threat alerts.By combining packet metadata analysis, flow telemetry, and historical modeling, Gcore helps organizations detect stealth attacks long before traditional security controls react.Automated response to contain threats at network speedDetection is only half the battle. Once an anomaly is identified, defenders must act within seconds to prevent damage.Real-world example: DNS amplification attackIf a volumetric DNS amplification attack begins saturating a branch office's upstream link, automated systems can:Apply ACL-based rate limits at the nearest edge routerFilter malicious traffic upstream before WAN degradationAlert teams for manual inspection if thresholds escalateSimilarly, if lateral movement is detected inside a cloud deployment, dynamic firewall policies can isolate affected subnets before attackers pivot deeper.Gcore’s network automation frameworks integrate real-time AI decision-making with response workflows, enabling selective throttling, forced reauthentication, or local isolation—without disrupting legitimate users. Automation means threats are contained quickly, minimizing impact without crippling operations.Hardening DDoS mitigation against evolving attack patternsDDoS attacks have moved beyond basic volumetric floods. Today, attackers combine multiple tactics in coordinated strikes. Common attack vectors in modern DDoS include the following:UDP floods targeting bandwidth exhaustionSSL handshake floods overwhelming load balancersHTTP floods simulating legitimate browser sessionsAdaptive multi-vector shifts changing methods mid-attackReal-world case study: ISP under hybrid DDoS attackIn recent years, ISPs and large enterprises have faced hybrid DDoS attacks blending hundreds of gigabits per second of L3/4 UDP flood traffic with targeted SSL handshake floods. Attackers shift vectors dynamically to bypass static defenses and overwhelm infrastructure at multiple layers simultaneously. Static defenses fail in such cases because attackers change vectors every few minutes.Building resilient networks through self-healing capabilitiesEven the best defenses can be breached. When that happens, resilient networks must recover automatically to maintain uptime.If BGP route flapping is detected on a peering session, self-healing networks can:Suppress unstable prefixesReroute traffic through backup transit providersPrevent packet loss and service degradation without manual interventionSimilarly, if a VPN concentrator faces resource exhaustion from targeted attack traffic, automated scaling can:Spin up additional concentratorsRedistribute tunnel sessions dynamicallyMaintain stable access for remote usersGcore’s infrastructure supports self-healing capabilities by combining telemetry analysis, automated failover, and rapid resource scaling across core and edge networks. This resilience prevents localized incidents from escalating into major outages.Securing the edge against decentralized threatsThe network perimeter is now everywhere. Branches, mobile endpoints, IoT devices, and multi-cloud services all represent potential entry points for attackers.Real-world example: IoT malware infection at the branchMalware-infected IoT devices at a branch office can initiate outbound C2 traffic during low-traffic periods. Without local inspection, this activity can go undetected until aggregated telemetry reaches the central SOC, often too late.Modern edge security platforms deploy the following:Real-time traffic inspection at branch and edge routersBehavioral anomaly detection at local points of presenceAutomated enforcement policies blocking malicious flows immediatelyGcore’s edge nodes analyze flows and detect anomalies in near real time, enabling local containment before threats can propagate deeper into cloud or core systems. Decentralized defense shortens attacker dwell time, minimizes potential damage, and offloads pressure from centralized systems.How Gcore is preparing networks for the next generation of threatsThe threat landscape will only grow more complex. Attackers are investing in automation, AI, and adaptive tactics to stay one step ahead. Defending modern networks demands:Full-stack visibility from core to edgeAdaptive defense that adjusts faster than attackersAutomated recovery from disruption or compromiseDecentralized detection and containment at every entry pointGcore Edge Security delivers these capabilities, combining AI-enhanced traffic analysis, real-time mitigation, resilient failover systems, and edge-to-core defense. In a world where minutes of network downtime can cost millions, you can’t afford static defenses. We enable networks to protect critical infrastructure without sacrificing performance, agility, or resilience.Move faster than attackers.

Introducing FastEdge Triggers: real-time edge logic
When you're building real-time applications, whether for streaming platforms, SaaS dashboards, or security-sensitive services, you need content that adapts on the fly. Blocking suspicious IPs, injecting personalized content, transforming media on the edge—these should be fast, scalable, and reliable.Until now, they weren't.Developers and technical teams often had to work across multiple departments to create brittle, hardcoded solutions. Each use case, like watermarking video or rewriting headers, required a custom integration. There was no easy way to run logic dynamically at the edge. That changes with FastEdge Triggers.Real-time logic, built into the edgeFastEdge Triggers let you execute custom serverless logic at key moments in the HTTP lifecycle:on_request_headerson_request_bodyon_response_headerson_response_bodyFastEdge is built on the proxy-wasm standard, making it easy to adapt existing proxy-wasm applications (e.g., for Envoy or Kong) for use with Gcore. These trigger types align directly with proxy-wasm conventions, meaning less friction for developers familiar with modern proxy architectures.This means that you can now:Authenticate users' tokens, such as JWTBlock access by IP, region, or user agentInject CSS, HTML, or JavaScript into responsesTransform images or convert markdown to HTML before deliveryAdd security tokens or watermarks to video contentRewrite or sanitize request headers and bodiesNo backend round-trips. No manual routing. Just real-time, programmable edge behavior, backed by Gcore's global infrastructure.While FastEdge enables instant logic execution at the edge, response-stage triggers (on_response_headers and on_response_body) naturally depend on receiving data from the origin before acting. Even so, transformations happen at the edge, reducing backend load and improving overall efficiency.Our architecture means that FastEdge logic is executed in ultra-low-latency environments, tightly coupled with CDN. Triggers can be layered across multiple stages of a request without performance degradation.Built for developersFastEdge Triggers were built to solve three core pain points for technical teams:Hard to scale: Custom logic used to require bespoke, team-specific workaroundsHard to maintain: Even single-team solutions became brittle without proper edge infrastructureLimited flexibility: Legacy CDN logic couldn't support complex, dynamic behaviorWith FastEdge, developers have full control: no DevOps bottlenecks, no workarounds, no compromises. Logic runs at the edge, not your origin, minimizing backend exposure. FastEdge apps execute in isolated, sandboxed environments, reducing the risk of vulnerabilities that might otherwise be introduced when logic runs on central infrastructure.How it works behind the scenesEach FastEdge application is written in Rust or AssemblyScript and connected to the HTTP request lifecycle through Gcore's configuration interface. Apps are linked to trigger types through the CDN resource settings page in the Gcore Customer Portal.Configuring FastEdge Triggers from the CDN resource settings screen in the Gcore Customer PortalHere's what happens under the hood:You assign a FastEdge app to a trigger point.Our Core Proxy detects that trigger and automatically routes execution through your custom logic.The result is returned before hitting cache or origin, modified, enriched, and secured.This flow is deeply integrated with our CDN, delivering minimal latency with zero friction.A sequence diagram showing how FastEdge Triggers works under the hood A real-life use case: markdown to HTML at the edgeHere's a real-world example that shows how FastEdge Triggers can power multi-step content transformation without a single backend server.One customer wanted to serve Markdown-based documentation as styled HTML, without spinning up infrastructure. Using this FastEdge app written in Rust, they achieved just that.The app listens at three trigger points: on_request_headers, on_response_headers, and on_response_bodyIt detects requests for .md files and converts them on the flyThe HTML is served directly via CDN, no origin compute requiredYou can see it live here:README renderedTerraform docs renderedThis use case showcases FastEdge's ability to orchestrate multi-stage logic at the edge: ideal for serverless documentation, lightweight rendering, or content transformation pipelines.Ready to build smarter at the edge?FastEdge Triggers are available now for all FastEdge customers.

How to choose the right CDN provider in a turbulent marketplace
In a CDN marketplace marked by provider shutdowns, price hikes, and shifting priorities, reliability is survival. If your current provider folds, you're not just facing downtime—you're losing revenue and customer trust. For the world’s top 2,000 companies, the total annual downtime cost is $400 billion, eroding 9% of profits. Choosing the right CDN partner isn’t just about performance, it’s about protecting your business from disruption.In this guide, we show you how to identify early warning signs, evaluate providers, and switch before your business takes the hit.Red flags: signs that it’s time to consider a new CDN providerIf you’re experiencing any of the following issues with your current CDN provider, it might be time to reconsider your current setup.Slower load times: If you’ve noticed lagging performance, your CDN provider may be running on outdated infrastructure or not investing in upgrades.Rising costs: Increasing prices without additional value? A higher bill and the same service is a major red flag.Uncertainty about long-term service: Look for clear communication and a demonstrated commitment to infrastructure investment, essential a market where providers frequently consolidate and shift focus.Your CDN should scale with you, not hold you back. Prioritize a partner who can evolve with your needs and support your long-term success.5 must-haves when choosing a CDN partnerNot all CDNs are created equal. Before switching, compare providers across these five key factors.Performance: Check real-world performance benchmarks and global coverage maps to understand how a CDN will serve your audience in key regions. Throughput (the amount of data that can be successfully delivered from a server to an end user over a specific period of time) and low latency are non-negotiable when choosing a CDN provider.Pricing: Before signing up, it’s essential to know what is and isn’t included in the price in case there are hidden fees. Look for predictable billing, volume-based tiers, and transparent overage charges to avoid surprise costs. Avoid vendors who lure you in with low rates, then add hidden overage fees.Security: Choose a CDN that offers built-in protection out of the box: DDoS mitigation, TLS, WAF, and API security. Bonus points for customizable policies that fit your stack. Strong security features should be standard for CDNs to combat advanced cyber threats.Edge computing: When it comes to Edge computing, understanding the power of this strategic CDN add-on can give you a significant advantage. Look for CDN providers that offer flexible edge compute capabilities, so you can process data closer to users, reduce latency, and improve response times.Future-proofing: The CDN market’s volatility makes partnering with providers with long-term stability vital. Pick a provider that’s financially solid, tech-forward, and committed to innovation—not just sticking around to get acquired.Choosing a new provider may feel like a challenge, but the long-term payoff—improved performance, lower risk, and a future-ready infrastructure—makes it well worth it. By picking a CDN partner that meets your needs now and for the future, you’ll receive fast, personalized, and secure experiences that truly stand out.What makes Gcore CDN different?Gcore CDN isn’t just another CDN, we’re your long-term performance partner.

How gaming studios can use technology to safeguard players
Online gaming can be an enjoyable and rewarding pastime, providing a sense of community and even improving cognitive skills. During the pandemic, for example, online gaming was proven to boost many players’ mental health and provided a vital social outlet at a time of great isolation. However, despite the overall benefits of gaming, there are two factors that can seriously spoil the gaming experience for players: toxic behavior and cyber attacks.Both toxic behavior and cyberattacks can lead to players abandoning games in order to protect themselves. While it’s impossible to eradicate harmful behaviors completely, robust technology can swiftly detect and ban bullies as well as defend against targeted cyberattacks that can ruin the gaming experience.This article explores how gaming studios can leverage technology to detect toxic behavior, defend against cyber threats, and deliver a safer, more engaging experience for players.Moderating toxic behavior with AI-driven technologyToxic behavior—including harassment, abusive messages, and cheating—has long been a problem in the world of gaming. Toxic behavior not only affects players emotionally but can also damage a studio’s reputation, drive churn, and generate negative reviews.The online disinhibition effect leads some players to behave in ways they may not in real life. But even when it takes place in a virtual world, this negative behavior has real long-term detrimental effects on its targets.While you can’t control how players behave, you can control how quickly you respond.Gaming studios can implement technology that makes dealing with toxic incidents easier and makes gaming a safer environment for everyone. While in the past it may have taken days to verify a complaint about a player’s behavior, today, with AI-driven security and content moderation, toxic behavior can be detected in real time, and automated bans can be enforced. The tool can detect inappropriate images and content and includes speech recognition to detect derogatory or hateful language.In gaming, AI content moderation analyzes player interactions in real time to detect toxic behavior, harmful content, and policy violations. Machine learning models assess chat, voice, and in-game media against predefined rules, flagging or blocking inappropriate content. For example, let’s say a player is struggling with in-game harassment and cheating. With AI-powered moderation tools, chat logs and gameplay behavior are analyzed in real time, identifying toxic players for automated bans. This results in healthier in-game communities, improved player retention, and a more pleasant user experience.Stopping cybercriminals from ruining the gaming experienceAnother factor negatively impacting the gaming experience on a larger scale is cyberattacks. Our recent Radar Report showed that the gaming industry experienced the highest number of DDoS attacks in the last quarter of 2024. The sector is also vulnerable to bot abuse, API attacks, data theft, and account hijacking.Prolonged downtime damages a studio’s reputation—something hackers know all too well. As a result, gaming platforms are prime targets for ransomware, extortion, and data breaches. Cybercriminals target both servers and individual players’ personal information. This naturally leads to a drop in player engagement and widespread frustration.Luckily, security solutions can be put in place to protect gamers from this kind of intrusion:DDoS protection shields game servers from volumetric and targeted attacks, guaranteeing uptime even during high-profile launches. In the event of an attack, malicious traffic is mitigated in real-time, preventing zero downtime and guaranteeing seamless player experiences.WAAP secures game APIs and web services from bot abuse, credential stuffing, and data breaches. It protects against in-game fraud, exploits, and API vulnerabilities.Edge security solutions reduce latency, protecting players without affecting game performance. The Gcore security stack helps ensure fair play, protecting revenue and player retention.Take the first steps to protecting your customersGaming should be a positive and fun experience, not fraught with harassment, bullying, and the threat of cybercrime. Harmful and disruptive behaviors can make it feel unsafe for everyone to play as they wish. That’s why gaming studios should consider how to implement the right technology to help players feel protected.Gcore was founded in 2014 with a focus on the gaming industry. Over the years, we have thwarted many large DDoS attacks and continue to offer robust protection for companies such as Nitrado, Saber, and Wargaming. Our gaming specialization has also led us to develop game-specific countermeasures.

How to choose the right technology tools to combat digital piracy
One of the biggest challenges facing the media and entertainment industry is digital piracy, where stolen content is redistributed without authorization. This issue causes significant revenue and reputational losses for media companies. Consumers who use these unregulated services also face potential threats from malware and other security risks.Governments, regulatory bodies, and private organizations are increasingly taking the ramifications of digital piracy seriously. In the US, new legislation has been proposed that would significantly crack down on this type of activity, while in Europe, cloud providers are being held liable by the courts for enabling piracy. Interpol and authorities in South Korea have also teamed up to stop piracy in its tracks.In the meantime, you can use technology to help stop digital piracy and safeguard your company’s assets. This article explains anti-piracy technology tools that can help content providers, streaming services, and website owners safeguard their proprietary media: geo-blocking, digital rights management (DRM), secure tokens, and referrer validation.Geo-blockingGeo-blocking (or country access policy) restricts access to content based on a user’s geographic location, preventing unauthorized access and limiting content distribution to specific regions. It involves setting rules to allow or deny access based on the user’s IP address and location in order to comply with regional laws or licensing agreements.Pros:Controls access by region so that content is only available in authorized marketsHelps comply with licensing agreementsCons:Can be bypassed with VPNs or proxiesRequires additional security measures to be fully effectiveTypical use cases: Geo-blocking is used by streaming platforms to restrict access to content, such as sports events or film premieres, based on location and licensing agreements. It’s also helpful for blocking services in high-risk areas but should be used alongside other anti-piracy tools for better and more comprehensive protection.Referrer validationReferrer validation is a technique that checks where a content request is coming from and prevents unauthorized websites from directly linking to and using content. It works by checking the “referrer” header sent by the browser to determine the source of the request. If the referrer is from an unauthorized domain, the request is blocked or redirected. This allows only trusted sources to access your content.Pros:Protects bandwidth by preventing unauthorized access and misuse of resourcesGuarantees content is only accessed by trusted sources, preventing piracy or abuseCons:Can accidentally block legitimate requests if referrer headers are not correctly sentMay not work as intended if users access content via privacy-focused methods that strip referrer data, leading to false positivesTypical use cases: Content providers commonly use referrer validation to prevent unauthorized streaming or hotlinking, which involves linking to media from another website or server without the owner’s permission. It’s especially useful for streamers who want to make sure their content is only accessed through their official platforms. However, it should be combined with other security measures for more substantial protection.Secure tokensSecure tokens and protected temporary links provide enhanced security by granting temporary access to specific resources so only authorized users can access sensitive content. Secure tokens are unique identifiers that, when linked to a user’s account, allow them to access protected resources for a limited time. Protected temporary links further restrict access by setting expiration dates, meaning the link becomes invalid after a set time.Pros:Provides a high level of security by allowing only authorized users to access contentTokens are time-sensitive, which prevents unauthorized access after they expireHarder to circumvent compared to traditional password protection methodsCons:Risk of token theft if they’re not managed or stored securelyRequires ongoing management and rotation of tokens, adding complexityCan be challenging to implement properly, especially in high-traffic environmentsTypical use cases: Streaming platforms use secure tokens and protected temporary links so only authenticated users can access premium content, like movies or live streams. They are also useful for secure file downloads or limiting access to exclusive resources, making them effective for protecting digital content and preventing unauthorized sharing or piracy.Digital rights managementDigital rights management (DRM) refers to a set of technologies designed to protect digital content from unauthorized use so that only authorized users can access, copy, or share it, according to licensing agreements. DRM uses encryption, licensing, and authentication mechanisms to control access to digital resources so that only authorized users can view or interact with the content. While DRM offers strong protection against piracy, it comes with higher complexity and setup costs than other security methods.Pros:Robust protection against unauthorized copying, sharing, and piracyHelps safeguard intellectual property and revenue streamsEnforces compliance with licensing agreementsCons:Can be complex and expensive to implementMay cause inconvenience for users, such as limiting playback on unauthorized devices or restricting sharingPotential system vulnerabilities or compatibility issuesTypical use cases: DRM is commonly used by streaming services to protect movies, TV shows, and music from piracy. It can also be used for e-books, software, and video games, ensuring that content is only used by licensed users according to the terms of the agreement. DRM solutions can vary, from software-based solutions for media files to hardware-based or cloud-based DRM for more secure distribution.Protect your content from digital piracy with GcoreDigital piracy remains a significant challenge for the media and entertainment industry as it poses risks in terms of both revenue and security. To combat this, partnering with a cloud provider that can actively monitor and protect your digital assets through advanced multi-layer security measures is essential.At Gcore, our CDN and streaming solutions give rights holders peace of mind that their assets are protected, offering the features mentioned in this article and many more besides. We also offer advanced cybersecurity tools, including WAAP (web application and API protection) and DDoS protection, which further integrate with and enhance these security measures. We provide trial limitations for streamers to curb piracy attempts and respond swiftly to takedown requests from rights holders and authorities, so you can rest assured that your assets are in safe hands.Get in touch to learn more about combatting digital piracy
