PerimAssure product

Continuous external security.

PerimAssure replaces stale perimeter snapshots with continuous, evidence-led visibility. It gives engineering and security leaders the evidence to find material external weaknesses, understand what changed and act.

Scheduled attack-surface monitoring

Assure runs monthly and Assure+ runs daily to track exposed services, subdomains, APIs, cloud storage and perimeter changes.

Technology and CVE intelligence

Observed technologies are fingerprinted and matched to relevant emerging vulnerabilities instead of generic CVE lists.

Evidence-led verification

Captured HTTP, DNS and TLS evidence is cross-checked before High or Critical candidates are presented as confirmed findings.

Decision-ready reporting

A higher-is-better Security Posture Score, measured changes, classified endpoints and protected canonical PDFs support technical and executive action.

From a free snapshot to verified continuous coverage

Start with a passive scan, verify ownership, authorise safe testing and choose the level of ongoing protection your estate requires.
