Know what you expose to the internet — as it changes.
Ongoing discovery and monitoring of your external attack surface — domains, hosts, and services — so new exposure is seen as it appears, not after it’s exploited.
- Senior-led delivery.
- Vendor-independent.
- Evidence-driven reporting.
Your internet-facing surface changes daily as teams ship, spin up infrastructure, and connect third parties. The assets you’ve forgotten about are usually the ones that matter — a stray subdomain, a management plane left open, a service that drifted public. Attack-surface monitoring keeps an external inventory current so nothing exposed goes unseen.
The platform discovers and tracks your external footprint continuously and flags meaningful change — a newly exposed service, an expiring certificate, an unexpected host — so your team reacts to exposure as it appears rather than at the next review.
What it does
External discovery
- Ongoing discovery of your internet-facing domains, subdomains, hosts, and services — including the shadow assets no one remembers standing up.
Change monitoring
- The surface is tracked over time and meaningful change is flagged — a newly exposed service, an open management plane, a host that drifted public.
Exposure context
- Findings are framed by what they expose and why it matters, so the signal is actionable rather than a raw list of everything reachable.
Senior escalation
- Material exposure is escalated to the senior team for validation and, where it warrants it, a deeper look through a point-in-time engagement.
What you get
- A current inventory of your internet-facing assets — including the ones your team has lost track of.
- Alerts on meaningful change to the external surface, framed by exposure rather than noise.
- Senior validation of material findings, not just an automated feed to triage yourself.
- A clean route into a penetration test or assessment where the exposure warrants depth.
Frequently asked questions
How is this different from a penetration test?
- Attack-surface monitoring tells you what is exposed and when it changes, continuously. A penetration test proves what an attacker could do with that exposure, in depth, at a point in time. Most teams use both.
Does it find shadow IT and forgotten assets?
- That’s a core purpose — ongoing external discovery surfaces the subdomains, hosts, and services that aren’t in anyone’s inventory.
Will we be flooded with alerts?
- No. Findings are framed by exposure and material change, and the senior team validates what matters — the goal is actionable signal, not raw noise.
