Penetration Testing
Reveal your technical risk
SPEAK TO THE TEAMPenetration Testing remains one of the most crucial activities in your Security mix.
Attack Surface Management (ASM) and vulnerability scanning tools provide continuous, broad-scope visibility and risk identification, but they work best when complimented with sophisticated, multi-vector attack simulation.
Invest in the creativity, lateral thinking, and threat awareness of a skilled, CREST Registered Tester (CRT) team – something tech alone simply can’t provide.
Our Penetration Testing Partners
CREST accredited expertise
All our Penetration Testers are CREST accredited making them suitable for the most complex and classified testing engagements. With CREST accreditation, you know engagements will be carried out using the most appropriate approach, metrics, and reporting. Our CRTs also cover a range of specialisms across different systems, environments, and industries, ensuring maximum relevance to your organisation and Security profile.
Invest in high-quality adversarial validation of your defences and deliver outcomes that drive positive change in your organisation.
Proactively reduce risk
Quantify your organisation’s technical risk exposure before threat actors have their turn. Penetration Testing reveals the true extent of your exploitable risk and the real-world impact these flaws could lead to. Equip your team to remediate based on risk and impact, reduce your attack surface, and avoid the constant cat and mouse between threat actor and victim.
Optimise Security investment
Our Penetration Testing engagements deliver clear, prioritised insights into the Security weaknesses and deficiencies most likely to damage your organisation, threaten operability, and lead to financial harm. Inform your investment decisions, ensuring that new and existing tools, training, and processes address your highest-risk areas and deliver the greatest ROI.
