Attack Surface Management

ASM Isn’t Asset Inventory.
It’s Internet Visibility.

Most ASM tools infer your attack surface from DNS records and stale, external signals.
Censys maps the global Internet across all 65K ports to show what attackers actually see.

Why Exposure Management Teams Choose Censys

How ASM Fits Into Your Security Operations

Find what others miss

Use first-party scanning to discover Internet-exposed assets (including services on nonstandard ports, hosts using self-signed certificates, and even hosts in residential networks) so your inventory reflects what attackers can actually reach.

Act on ARC Rapid Response

When Censys ARC flags a new critical exposure or active exploitation, use the notification as a trigger to confirm reachability in seconds, identify every affected Internet-facing asset, and launch targeted remediation through your existing workflows.

Detect exposure drift immediately

Monitor your surface continuously and alert on meaningful deltas (new hosts, ports, certs, services) so “new exposure” becomes a ticket within an hour, not a quarterly surprise.

Push findings into remediation workflows

Integrate with ticketing, VM, and security tooling to auto-create, route, and track remediation tasks so ASM becomes part of day-to-day operations, not another dashboard.

Audit-ready reporting, always current

Generate executive and audit-friendly views that map exposure trends and remediation progress so leaders can show risk reduction with evidence, not anecdotes.

Internet-wide threat investigation

When ASM finds a risky exposure, pivot straight into Censys Platform to investigate the broader threat: identify potential adversaries, track reused certificates and domains, understand campaign patterns, and turn “fix this asset” into “disrupt attackers” intelligence for your SOC.
