For enterprises with threat intelligence teams that need to defend against targeted attacks, Censys provides a critical layer of data.

Adversaries typically need an Internet-accessible server (known as a command and control or C2 server) in order to remotely control and exfiltrate data from a target. Censys data helps you identify attacker infrastructure—even if it’s dormant—in order to contain existing threats and to prevent new ones.

One way to start hunting for threats is by analyzing suspicious links or malware found in phishing emails. Once you’ve identified a potentially harmful IP address or certificate, you can block your users from accessing that server, ultimately preventing attacks on your organization.
