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'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Exposed and outdated services tested for known and novel weaknesses.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.

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.
