External attack surface management
Know your attack surface as it exists today.
ExposureSignal continuously discovers the assets connected to your organization, enriches them with threat context, and turns the changing perimeter into a ranked, evidence-backed worklist.
What you gain
Replace incomplete inventory with an attacker-view map.
The signal blends asset exposure, credential pressure, control gaps, and projected loss into one operating picture for security and leadership.
Identify primary domains, subdomains, third-party hosts, and forgotten properties that expand your reachable footprint.
See the public services, technologies, certificates, and access points available to an outside observer.
Catch new and altered assets before they become permanent blind spots in a quarterly inventory process.
How it works
Build, validate, and maintain the outside-in inventory.
Discover connected assets
Expand from known domains into related infrastructure using DNS, certificate, service, and hosting signals.
Fingerprint exposed technology
Identify reachable services and technologies that shape exploitability and remediation ownership.
Add threat and business context
Distinguish an ordinary internet asset from an exposed system tied to active exploitation or a critical workflow.
Monitor surface changes
Track additions, removals, certificate events, and posture changes as infrastructure and vendors evolve.
From evidence to action
Turn attack-surface visibility into reduction.
Discovery becomes useful when teams can identify ownership, understand urgency, and verify that the exposed condition changed.
Investigate unknown internet assets
Determine whether each asset is approved, vendor-managed, abandoned, or connected to a live business process.
Restrict unnecessary public services
Remove avoidable reachability and reduce the number of pathways available for scanning and exploitation.
Retire stale infrastructure
Eliminate forgotten domains, systems, and certificates that no longer provide business value but still carry risk.
Start with a clear signal
Turn your external footprint into a prioritized response plan.
See your current external exposure, the findings that deserve attention first, and the evidence your team can use to act.
