External Perimeter Test
Discover, enumerate, and safely exploit your internet-facing assets before an attacker maps the same ground.
Your perimeter is whatever an attacker can reach from the open internet — and it's usually larger than teams think.
We map it, fingerprint what's running, and manually attempt exploitation to prove real impact. The result is a clear picture of your external exposure, ranked by what an attacker could actually do with it.
What's included
Asset discovery — enumerate the internet-facing hosts, services, and shadow infrastructure attached to your name.
Service & version enumeration — fingerprint what's running and flag outdated or misconfigured services.
Manual exploitation — safe, hands-on attempts to prove real impact, not just theoretical exposure.
Prioritized findings — every issue ranked by exploitability and business risk, with clear remediation.
How the engagement runs
Every engagement follows the same four-stage path — scope, test, report, verify. Scope and price are fixed in writing before any testing begins, and a re-test of the findings is included.
Your external attack surface
The perimeter is bigger than most teams realize. We enumerate every internet-facing category an attacker would.
Web & app servers
Public sites, portals, and the apps running on them.
Mail & collaboration
Mail servers, webmail, and exposed collaboration tools.
Remote access & VPN
VPN gateways, RDP, and remote-access endpoints.
DNS & subdomains
Records, subdomains, and takeover-prone entries.
Exposed admin panels
Login pages and management interfaces facing the internet.
Forgotten & shadow assets
Stale hosts and shadow IT nobody remembers running.
What you get
Executive summary
A plain-language overview of risk and business impact for leadership and whoever signs off on remediation.
Technical findings
Each issue ranked by real risk, with reproduction steps and concrete remediation guidance for your engineers.
Remediation support
We stay available while you fix — to answer questions and clarify findings, not just hand over a PDF.
Free re-test
Once you've remediated, we re-test the specific findings to confirm they're actually closed.
Know your real exposure.
Fixed scope, fixed price, and a report you can act on — with a free re-test once you've remediated.
