External Penetration Testing

We attack your internet-facing perimeter the way a real adversary would, finding the exposed services and weak points that give attackers their first foothold.

What we test

What's covered

  • Attack-surface discovery

    Everything you expose to the internet — including the hosts you'd forgotten about.

  • Service exploitation

    Exposed and outdated services tested for known and novel weaknesses.

  • Remote access & VPN

    The security of your remote-access gateways and their authentication.

  • Web-facing applications

    Login portals and admin interfaces exposed to the internet.

  • Email & DNS

    Spoofing protections (SPF, DKIM, DMARC) and DNS misconfiguration.

  • Credential exposure

    Leaked and reused credentials that unlock your perimeter.

How it works

A clear, transparent process

  1. Scope

    Get an instant estimate, then a short call to confirm targets, timing and rules of engagement.

  2. Test

    Hands-on testing by an experienced consultant, with critical issues flagged to you as they're found.

  3. Report

    A clear report: executive summary, risk-rated findings, evidence and practical fixes.

  4. Retest

    We check your fixes and confirm they work.

FAQ

Common questions

What's the difference between external and internal testing?

External testing starts from the internet, like an outside attacker. Internal testing starts from inside your network, modelling an attacker who already has a foothold. Many organisations do both.

How is it priced?

By the number of in-scope IP addresses and exposed services. The instant estimate tool gives a guide price.

Will testing disrupt our services?

We test carefully and agree rules of engagement first. Genuinely disruptive checks are only run with your explicit approval and at an agreed time.

How often should we test externally?

At least annually, and after any significant change to your internet-facing systems.
