Use Border Gateway Protocol (BGP) to secure your network edge with real-time protection against malicious IPs. Deploy threat intelligence data at the routing level using BGP, and automatically block communications to and from IPs involved in the most dangerous cybercrimes, before they cause irreparable damage. This solution works with any BGP-capable device, including routers and modern firewalls, making it simple to integrate into existing infrastructure.
Strengthen your perimeter security and build lasting resilience, creating a safer, more secure network.
Access the Data
Border Gateway Protocol
Block the worst-of-the-worst at your network perimeter, taking advantage of your existing BGP-capable appliances, including routers and modern firewalls. Our data available via BGP Firewall carries minimal risk of blocking legitimate traffic, given its high certainty of maliciousness.
There are a lot of blocklists out there but the only one that’s ever been super trustworthy has been Spamhaus.
