External network testing
We test your internet-facing systems, such as firewalls, VPNs, remote access and email, for ways in from outside.
Find out how an attacker would get into your business before they do. Our in-house team simulates real-world attacks on your network, applications and people, then shows you exactly what to fix first.

A penetration test, or pen test, is a controlled, authorised attack on your systems. Our testers look for weaknesses the way a real attacker would, then safely try to exploit them to show what could actually happen, from stolen data to a full network compromise.
Unlike an automated vulnerability scan, a pen test shows how individual weaknesses can be chained together, which risks really matter, and how to fix them. It is a common requirement for cyber insurance, client security questionnaires and certifications like ISO 27001.


We understand the importance of protecting data, and we set ourselves apart through our ISO 27001 certification and SMB1001 Gold (Level 3) certification with CyberCert. From safeguarding company data to client information, we’re dedicated to upholding the highest standards of information security.
We test your internet-facing systems, such as firewalls, VPNs, remote access and email, for ways in from outside.
We simulate an attacker who is already inside, such as a compromised laptop or a malicious insider, to see how far they could get.
We test your websites, portals and web apps for flaws like weak authentication, injection and exposed data.
We check your Wi-Fi for weak encryption, rogue access points and paths from guest networks into your business systems.
We test how your team responds to realistic phishing emails, and use the results to target security awareness training.
Once fixes are in place, we retest to confirm each issue is resolved, so you have evidence for insurers, clients and auditors.
We agree what is in scope, the type of testing, timing and rules of engagement, so testing is safe and controlled.
Our in-house testers combine automated tools with manual techniques to find and safely exploit weaknesses.
You get a clear report with an executive summary, each finding rated by risk, and practical steps to fix it.
We walk you through the results, help remediate the issues, and retest to confirm they are closed.
Because our testers sit alongside our engineers, we do not just hand you a list of problems. We help you fix them, and we understand the systems small and medium businesses actually run.

A penetration test is an authorised, simulated cyber attack on your systems. It finds weaknesses, safely shows how they could be exploited, and gives you a prioritised plan to fix them.
A vulnerability scan is automated and lists known weaknesses. A pen test adds skilled manual testing to show which weaknesses can actually be exploited, how they could be combined, and what the real business impact would be.
At least once a year, and after major changes such as a new system, office move or significant upgrade. Some insurers, clients and standards require annual testing.
Testing is planned and scoped with you in advance, and we agree timing and rules of engagement to keep disruption to a minimum. Higher-risk tests can be scheduled outside business hours.
No. Our penetration testing is carried out by our own in-house team, who also help you fix what they find.
A written report with an executive summary, detailed findings rated by risk, evidence and clear remediation steps, plus a walkthrough of the results with our team.
