Stop API Attacks Before They Impact Your Business
Get full lifecycle API protection from discovery to real time threat prevention so you can innovate faster without increasing risk.
APIs are your fastest-growing attack surface
83% of web traffic
APIs now handle the majority of web traffic, yet most lack dedicated runtime protection beyond a basic gateway.
Business logic attacks
Attackers abuse legitimate API functionality, valid calls, malicious intent, invisible to signature-based tools.
OWASP API Top 10
BOLA, broken authentication, and unrestricted resource consumption top the OWASP API Security Top 10, and most tools miss them.
Automated attacks
Automated bots enumerate endpoints, scrape data, and conduct account takeovers at speeds no manual defense can match.
Comprehensive approach for API protection
Discover your complete API landscape
Automatically discover, inventory, and tag every API, including shadow, zombie, and AI-agent APIs, across all environments, giving you instant visibility and a live governance baseline.
Identify vulnerable APIs
Audit every API endpoint for the vulnerabilities and misconfigurations attackers target, including all OWASP API Top 10 risks, before they're exploited.
Prevent API abuse and attacks
Use behavioral context to detect data leakage, suspicious usage patterns, malicious bots, and active API attacks, and block them in real time at the edge.
How Gcore API security works
API Discovery
Discover public, private, shadow, and deprecated APIs. Map endpoints across environments. Maintain a live inventory. Classify risk and sensitive data. Enable DevSecOps visibility.
API Schema Enforcement
Enforce a positive model via OpenAPI specs. Block malformed and out-of-spec traffic. Reject unexpected fields and payload manipulation. Stop threats before app logic runs.
Authentication control
Monitor JWTs, tokens, and sessions. Detect BOLA and broken auth flows. Identify replay and token abuse. Stop privilege escalation. Enforce object-level access control.
Real-time protection
Block OWASP API Top 10 threats inline. Prevent mass assignment and data leaks. Mitigate injection and API abuse. Enforce protection across our global edge with low-latency coverage.
Anomaly detection
Use ML-based behavioral analytics. Detect business logic abuse. Identify takeover and enumeration. Stop scraping and workflow abuse. Expose automated API attacks.
Real-time analytics
Access actionable security dashboards with flexible filters for investigations. Drill into specific API sessions or attack vectors. Accelerate incident response and root-cause analysis.
Business logic protection that understands your APIs
Traditional security tools inspect packets. Gcore API Security understands API intent.
Our engine analyzes relationships between endpoints, user roles, data objects, and transaction sequences to detect when valid API calls are being misused.
- Detect abuse of legitimate API functionality and business logic flows
- Protect multi-step transactional workflows from sequence manipulation
- Stop automated account enumeration, credential stuffing, and takeover
- Prevent API-driven data scraping and unauthorized bulk data extraction

Frequently Asked Questions
How does API security differ from traditional web application security?
Traditional web security focuses on web browsers and HTML traffic. API security protects machine-to-machine communication, JSON/XML data, and business logic workflows that power mobile apps, SaaS platforms, and integrations.
What is business logic protection and why do I need it?
Business logic attacks use legitimate API calls in unintended ways - like transferring money between accounts or accessing unauthorized data. These attacks look normal to traditional security tools but can cause massive business impact.
How quickly can I deploy Gcore API Security?
Most customers are protected within 24 hours. Our edge-native deployment requires no infrastructure changes - just point your DNS to Gcore and we handle the rest with automatic API discovery and policy creation.
Does API security impact application performance?
Gcore API Security adds less than 15ms of latency while providing comprehensive protection. Our edge network ensures your APIs remain fast and responsive even under attack.
