External Exposure Management

How Censys powers external exposure management

Find What Others Miss

First-party scanning uncovers Internet-exposed assets that internal tools overlook — services on non-standard ports, hosts with self-signed certificates, and assets in residential networks — so your inventory maps what attackers can actually reach.

ARC Rapid Response

When Censys ARC identifies a new critical exposure or active exploitation event, confirm reachability in seconds, find every affected internet-facing asset, and launch targeted remediation directly through your existing workflows.

Detect Exposure Drift Immediately

Monitor your attack surface continuously, alerting on meaningful changes — new hosts, ports, certificates, or services — so a new exposure becomes a remediation ticket within the hour rather than a quarterly surprise. Includes EPSS and KEV vulnerability risk scoring.

Push Findings Into Remediation Workflows

Integrate with ticketing, vulnerability management, and security tooling to automatically create, route, and close remediation tasks — embedding ASM findings into day-to-day operations rather than leaving them in a separate dashboard.

Audit-Ready Reporting

Generate executive-ready and audit-friendly reports mapping exposure trends and remediation progress — giving leadership evidence-based risk reduction stories, not anecdotes.

Internet-Wide Threat Investigation

When ASM surfaces a risky exposure, pivot directly into the Censys Platform to investigate adversary context — tracking reused certificates and domains and turning asset remediation findings into SOC-ready intelligence.

Key capabilities

First-party internet scanning covers all 65,000 ports, uncovering exposed assets that internal scanners miss — including services on non-standard ports, self-signed certificate hosts, and assets in residential network ranges
Censys ARC rapid-response capability lets teams confirm asset reachability in seconds when a critical vulnerability or active exploitation is flagged, enabling immediate targeted remediation
Continuous surface monitoring alerts on meaningful changes — new hosts, ports, certificates, or services — enriched with EPSS and KEV scoring so new exposures surface for remediation within hours
Native integrations with ticketing, vulnerability management, and security tooling auto-create and route remediation tasks, embedding ASM findings into day-to-day operations
Audit-ready reporting gives executives and compliance teams evidence-based views of exposure trends and remediation progress over time
From any flagged exposure, teams can pivot into the Censys Platform to investigate adversary infrastructure, track reused certificates and domains, and convert asset findings into broader threat intelligence

How It Works

Discover

Censys scans all 65,000 ports globally with first-party scanners, uncovering internet-exposed assets that internal tools miss — including services on non-standard ports, hosts in residential IP ranges, and assets with self-signed certificates that bypass conventional scanners.
Monitor

Continuous surface monitoring alerts on meaningful changes to your attack surface — new hosts, open ports, certificate reissues, or changed services — enriched with EPSS and KEV risk scoring so new exposures surface for remediation within hours, not quarterly reviews.
Respond

When a critical CVE or active exploitation event is flagged, Censys ARC confirms asset reachability in seconds and identifies every internet-facing asset in scope — enabling immediate targeted response before attackers can act on the exposure.
Remediate

Native integrations with ticketing, vulnerability management, and SIEM platforms automatically create and route remediation tasks, embedding ASM findings into existing day-to-day operations rather than leaving them isolated in a separate dashboard.
