Protect your network edge with the most up to date protection against botnets and external attacks on your servers.
Border Gateway Protocol (BGP) Feeds effortlessly block communications with IPs involved in the most dangerous cybercrimes and assist in stopping DDoS attacks.
Utilizing your existing BGP routers, you can maximize the benefits and protection you get from current equipment.
Standard routers running BGP accept advertised routes from other BGP routers, by default. This routine, automated process means that IP addresses with routing privileges are highly valued by cybercriminals.
Any routers within your network that are peered with the Spamhaus BGP router will not be able to communicate with botnet command and controllers (C&Cs), preventing loss of data and spamming from infected nodes on your network.
Network engineers and security operations centers [SOCs], plus anyone who manages their own network edge routers.
It takes just a few minutes to configure your edge router to peer with a Spamhaus BGP router.
After installing the “Botnet Controller List” (BCL) and “Do Not Route or Peer” (DROP) in your router’s routing table, communications with botnet C&Cs are blocked.
This prevents infected computers within your network from receiving instructions and malware updates. The BCL disrupts communication with the C&C servers, neutralizing botnet nodes within your network and stopping sensitive data egress, even though the devices have not yet had the malware removed.
Based on network size, starting from $2,500 per annum.
Block malicious traffic at your network edge using Do Not Route or Peer (DROP) & Botnet Controller Lists.
