Penetration Testing
Our accredited security specialists run safe, controlled tests to identify weaknesses in your systems — helping you address them before attackers can exploit them.
Using specialist threat intelligence and ethical hacking techniques, we simulate a real attempt to infiltrate your systems — identifying vulnerabilities that could compromise your business, across every angle of your estate.
Targets your internet-facing assets — firewalls, email servers and public systems — to identify perimeter vulnerabilities before attackers find them.
Examines what happens if internal access is compromised via credentials or phishing, and how far an attacker could move.
Targeted campaigns that raise staff awareness and measure your organisation's real-world resilience to social engineering.
Assesses both pre-login and authenticated areas of your applications for vulnerabilities attackers could exploit.
Reviews your company and guest Wi-Fi for encryption, configuration and access control weaknesses.
Reviews platforms including Microsoft 365, Google Workspace, AWS and Azure for misconfigurations and permission issues.
Our Approach
Automated scanners can only find what they're programmed to look for. Our testers combine specialist tooling with manual, hands-on techniques — the same creativity and persistence a real attacker would use — to uncover the issues a scan alone would miss.
Contact UsA penetration test is only as good as the process behind it. Here's exactly what happens when you work with us.
We agree exactly what's in scope, testing windows, and rules of engagement before anything begins.
Our accredited testers simulate real attack techniques against the agreed scope, safely and under control.
You receive a clear, prioritised report of findings, plus a debrief so your team understands exactly what to fix first.
Once remediated, we retest key findings to confirm the fixes actually closed the gap.

Meet the Team
We recently engaged Sophlee to carry out penetration testing and provide security advice for our trust. Their customer service has been excellent throughout the entire engagement. Communication was clear, responsive and professional, and they ensured we understood every stage of the process. The team delivered a thorough pentest with detailed findings and practical recommendations that we were able to implement quickly. They demonstrated strong technical knowledge, and their approach was supportive rather than overwhelming, which made the whole experience very positive. We are fully satisfied with the service provided and would happily recommend Sophlee for organisations seeking high-quality penetration testing and security advice.

A vulnerability scan is an automated sweep that flags known weaknesses. A penetration test goes further — a skilled tester actively tries to exploit those weaknesses, chain them together, and show you the real-world impact of a breach, not just a list of theoretical issues.
It depends on scope, but most engagements run from a few days to a couple of weeks, from active testing through to your final report and debrief.
You'll receive a clear, prioritised report and a debrief call so your team understands exactly what was found and what to fix first, in plain English rather than raw technical output.
Yes — once you've remediated the key findings, we retest to confirm the fixes have actually closed the gap.
Cyber Essentials Plus involves its own technical verification rather than a full penetration test, but many organisations choose to run a penetration test alongside or ahead of certification for a deeper level of assurance.
