External Exposure Check

See what your business exposes to the internet

An authorised reachability check across the full TCP range, from a fixed UK address. See every internet-facing service, what needs review, and keep the evidence.

Authorised checks only · UK-hosted · No credit card

What a check shows

Every internet-facing service, explained

Full TCP range checked

Every port from 1 to 65535 is checked, so nothing internet-facing is missed.

Risk, in plain English

Each observed service is banded Expected, Needs review, High concern, or Insufficient context, with the reason.

Evidence retained

Full evidence is kept for every check, so you can show what was reachable and when.

How it works

Authorised, contained, reproducible

Authorised only

A check runs only after you confirm you own or administer the target. The authorisation is recorded before anything is queued.

Fixed UK source

Checks run from a known UK address, so results are reproducible and the source can be quoted in reports.

No intrusive testing

TCP reachability and safe service detection only. No exploits, no brute force, no credential testing.
