Penetration Testing Services in London and Across the UK
Test Your Defences, Fix the Gaps and Retest With One Provider
Penetration testing is an authorised, simulated cyber attack on your systems, networks, applications or cloud environment, carried out by security professionals to find weaknesses a real attacker could use. Fitzrovia IT provides penetration testing to organisations across London and the UK.
A test report only helps if the issues get fixed. As a managed service provider, Fitzrovia IT can test your systems, carry out the remediation and retest to prove the issues are closed. That makes it a natural step towards Cyber Essentials Plus or ISO 27001.
HOW CAN WE HELP YOU TODAY?
OUR ACCREDITATIONS
Fitzrovia IT is a Cyber Essentials, IASME Cyber Assurance and Defence Cyber Certification Body, an NCSC Cyber Advisor, and is certified to ISO 27001 for information security.
What is Penetration Testing?
A penetration test, or pen test, is a controlled attack on your IT that shows how a real attacker could get in and what they could reach. Unlike an automated scan, testers use manual techniques to confirm which weaknesses can genuinely be exploited.
The results tell you which vulnerabilities matter most, how your defences hold up under pressure and what to fix first. Organisations commission pen tests every year, after major changes, before launching new systems or to meet customer and compliance requirements.

Frequently Asked Questions (FAQs)
-
What is the purpose of a penetration test?
A penetration test finds and confirms security weaknesses before attackers can exploit them.
-
How is penetration testing different from vulnerability scanning?
Vulnerability scanning is automated and lists possible issues. Penetration testing uses manual, simulated attacks to confirm which issues can actually be exploited.
-
How often should we run a penetration test?
Most organisations test at least once a year, and after major changes to systems or applications.
-
Will a penetration test disrupt our business?
No. Fitzrovia IT plans each test with you and runs it in a controlled way to avoid disruption.
-
Can you fix the issues you find?
Yes. As a managed service provider, Fitzrovia IT can carry out remediation and retest to confirm each issue is resolved.
