Attack Surface Review

Everything your organization exposes to the internet — mapped, ranked, and explained. Most companies are surprised by their own list.

Request a scoping call Our methodology
Why this matters: Attackers do not attack your company; they attack what your company forgot about. The old panel nobody decommissioned, the staging server with production data, the CI key leaked in a public repository — our research series tracks how single forgotten assets became full breaches. This review finds yours before someone else does.

What we cover

  • Domain and subdomain enumeration — including forgotten projects
  • Exposed services, admin panels, and management interfaces
  • Cloud storage and bucket exposure review
  • Leaked secrets and keys in public repositories
  • Third-party services and SaaS your org exposes
  • Risk-ranked inventory you can act on

How we test

1External enumeration

OSINT and scanning from the outside — exactly the view an attacker has, no insider access needed.

2Validation

Each finding verified by hand: what is actually exposed, what version, what data.

3Risk ranking

Ranked by real exploitability and business impact, not scanner severity.

4Action plan

A short, sequenced takedown and hardening list.

What you get

  • Complete external asset inventory
  • Risk-ranked exposure report
  • Sequenced remediation plan
  • Optional re-scan cadence to keep it current

Common questions

Do you need any access to do this?

No — that is the point. Everything in this review is visible from the outside, exactly as an attacker sees it.

Is this a one-time thing?

The first review establishes your baseline; attack surfaces drift, so most clients re-scan quarterly or after major changes.

How is this different from a vulnerability scan?

A scan checks known hosts for known CVEs. This first answers “what exists at all?” — the forgotten assets scans never see — then validates and ranks what matters.

Authorization first, always. Testing happens only with your written permission and agreed rules of engagement — the same ethics that govern responsible disclosure on this site.
