What is CHECK Penetration Testing?
CHECK is an accreditation scheme created by the National Cyber Security Centre (NCSC) and endorsed by the UK government.
It is used primarily to certify the cyber security experts working for government departments, public sector bodies, and other organisations considered a part of the UK’s Critical National Infrastructure (CNI).
Penetration Tests by CHECK-approved members use NCSC-recognised methods.

Our CHECK Penetration Testing Services
CHECK Infrastructure Penetration Test
One of our CHECK-certified consultants reviews your internet-facing infrastructure and your internal corporate network to identify potential vulnerabilities.
CHECK IT Health Check
Comprehensive NCSC and CREST-approved assessment for PSN compliance. We evaluate your external and internal systems, network devices, apps, and configurations to pinpoint vulnerabilities and confirm compliance with regulatory standards.
CHECK Web Application Penetration Test
A proactive security assessment performed by one of our CHECK-certified consultants to identify vulnerabilities within your web applications, APIs, and associated backend systems.
Methodology
We ensure testing has both depth and breadth by aligning with recognised methodologies such as CREST, OSSTMM, OWASP, and NIST.
This ensures a structured, consistent approach grounded in best practice and real-world threat intelligence.
We follow a clear seven-step process designed to deliver rigorous testing, meaningful insight, and practical remediation guidance at every stage.
We listen to your needs and develop a tailored project strategy, producing a scope that meets your unique requirements.
Where vulnerabilities are successfully exploited, our consultants assess their severity by determining which assets and networks can be accessed and what data may be exposed. Vulnerabilities are then ranked from low to critical within GuardNest.
We scan and enumerate the defined targets to identify existing vulnerabilities. This includes listening for open ports, identifying running services, and developing an attack plan based on the scan results.
Our consultants assess how deeply they can access your systems using leading industry techniques, custom-built tools, and their first-hand experience.
If a consultant successfully exploits a vulnerability, they assess its severity. This involves determining which assets and networks can be accessed and how much information can be gathered. Your vulnerabilities are then ranked from low to critical in GuardNest.
We publish the findings in a report on GuardNest, organised by category and type, with remediation advice for each exploit and vulnerability. On request, we also arrange debrief calls to review identified risks in detail and discuss remediation.
Your GuardNest licence includes continuous external infrastructure scanning to minimise risk between tests. We also offer a remediation check service, and every engagement includes a full consultative approach to ensure ongoing support even after the project is complete.
