You cannot defend an asset you do not know you own. Cloud sprawl, acquisitions, shadow IT, and forgotten infrastructure mean most organizations expose more than their asset inventory claims - and the gap is exactly where attackers look first.
We discover and continuously map your external attack surface from the outside in: every domain, host, service, certificate, and exposed application, attributed back to your organization. Each asset is assessed for exposure, fingerprinted for known weaknesses, and tracked as it changes.
The result is an authoritative, living inventory of what you present to the internet - so new exposure is caught as it appears rather than discovered during an incident.
Map your external footprint and confirm which assets genuinely belong to you, eliminating guesswork and noise.
Fingerprint each asset's services, technologies, and configuration to understand exactly what it presents to an attacker.
Rank exposures by exploitability and the sensitivity of what sits behind them, so the riskiest assets surface first.
Track the surface over time and alert on new or changed exposure, keeping the inventory accurate as your estate evolves.
Book a scoped assessment - we will map what is reachable, prove what is exploitable, and give you a ranked path to closing it before someone finds it first.
