Automated DDoS Protection with Gcore + FastNetMon
Real-time traffic monitoring and automatic redirection to our scrubbing center. Protect your network infrastructure with sub-second response times and zero operator intervention.

How automated protection works
Our integrated solution detects attacks and redirects traffic automatically using BGP mechanisms.
01
Real-time monitoring
FastNetMon Advanced monitors your traffic using NetFlow, sFlow, and IPFIX protocols to detect DDoS indicators instantly.
02
Automatic redirection
When an attack is detected, FastNetMon triggers BGP announcements to redirect affected network traffic to Gcore's scrubbing center.
03
Clean traffic delivery
Gcore filters out malicious traffic and returns clean traffic to your network via GRE tunnel, then automatically restores normal routing.
Protection activates in under 1 second with zero manual intervention required.
Key integration components
FastNetMon Advanced
Traffic analysis and anomaly detection
- Continuously analyzes network traffic patterns using multiple protocols including NetFlow, sFlow, and IPFIX. Detects DDoS attack indicators and manages BGP announcements through automated hook scripts for immediate response.
Integration Scripts
Open-source automation tools
- Uses notify_about_attack.py and other hook scripts from the official FastNetMon repository to initiate BGP announcements toward Gcore. These scripts are fully open-source and customizable for your specific network requirements.
Gcore Scrubbing Center
Advanced traffic filtering infrastructure
- Our global scrubbing centers receive redirected traffic, filter out malicious requests using advanced DDoS mitigation techniques, and return clean traffic to your network via secure GRE tunnels or other configured channels.
Integration requirements

BGP peering capability
Establish BGP peering between your network and Gcore infrastructure for route announcements.
IP routing flexibility
Ability to route your IP pool via Gcore using BYOIP or partial transit arrangements.
Return path setup
GRE tunnel or similar secure channel configured for clean traffic delivery back to your network.
FastNetMon installation
FastNetMon Advanced deployed with BGP integration and scripts from the official repository.
Benefits for your network

Automated DDoS response eliminates the need for manual operator intervention during attacks.
Sub-second response
Detection and traffic redirection happens in under 1 second for immediate threat mitigation.
Surgical precision
Only attacked prefixes are redirected, and only during active attacks, minimizing network disruption.
Perfect for these organizations
Internet service providers
Protect customer networks with automated DDoS mitigation that scales with your infrastructure growth.

Data centers

Frequently asked questions
How fast does the protection activate?
Protection activates in under 1 second from attack detection. FastNetMon detects DDoS indicators in real-time and immediately triggers BGP announcements to redirect traffic to our scrubbing centers.
Does this solution support both IPv4 and IPv6?
Yes, the Gcore + FastNetMon integration provides comprehensive protection for both IPv4 and IPv6 traffic with the same automated response capabilities.
What happens to legitimate traffic during an attack?
Legitimate traffic is preserved throughout the process. Gcore's scrubbing centers filter out only malicious traffic and return clean traffic to your network via secure GRE tunnels.
Do I need to transfer full routing control to Gcore?
No, you maintain full routing control. Only attacked prefixes are temporarily redirected during active attacks, and normal routing is automatically restored when attacks end.
Where can I find the integration scripts?
All integration scripts are available in the official FastNetMon repository on GitHub. The scripts are open-source and fully customizable.
