Scalable Security in Seconds

Stay protected as your network grows. Effortlessly apply the same ruleset across multiple instances.

Protect Your Network

Defend your network from malicious attacks by creating rules to only allow traffic from trusted sources. Filter traffic at the network layer using fine-grained control over who can access your Linodes.
