Stop Chasing Alerts. Start Confirming Threats.

Real-Time Visibility for Modern Security Operations

See what’s exposed, instantly

Get a single view of hosts and services—open ports, protocols, banners, and software fingerprints—so you can validate alerts and confirm exposure without bouncing between tools.

Follow the cert trail

Pivot through certificates, SANs, issuer chains, and linked domains to connect related infrastructure fast—ideal for scoping incidents and spotting attacker reuse across a campaign.

Turn investigations into monitors

Save key pivots as Collections and track changes over time—so “what we found” becomes “what we watch,” with alerts when infrastructure, exposure, or attributes shift.

Enrichment where alerts land

Push Censys context into your SIEM/SOAR/TIP and internal workflows, so triage and detections start with the facts—reducing manual enrichment and speeding decision-making.

Power playbooks, pipelines, and AI

Automate lookups with APIs and SDKs, standardize workflows at scale, and support AI initiatives with an MCP server—so Censys becomes a dependable backbone for automation-first security programs.
