Pentest Limited was formed in 2001. We are a leading provider of offensive information security services across the UK, Europe, USA and Asia. In 2019 the company was acquired by Shearwater Group plc.

We take an offensive approach to information security and through our consultancy, penetration testing and red teaming services we aim to uncover IT security vulnerabilities, support ongoing security efforts, increase the digital resilience of your organisation and to provide you with the security assurances you need.

Whatever your goals, we’re here to support you. It’s this support that truly sets us apart and our team will be on hand throughout engagements to impart their expert knowledge, deliver industry best practice and provide you with post-test remediation advice.

why choose us?

We operate globally as a trusted partner to security mature organisations, including global enterprises, public sector & private sector businesses of all sizes. But what truly sets us apart?

experience & expertise

Our team of security consultants have years of proven experience and a depth of expertise in application layer security. We invest significant time into security research projects, honing and developing skills which allow our consultants to deliver the best possible results for your organisation.

dedicated support

Every client is appointed a dedicated account manager to oversee the testing process. We give you access to our consultants throughout the engagement and provide your team with unparalleled post-test support.

tailored approach

No two organisations are the same and neither are our tests. We work closely with you to fully understand your goals, the services in question, security challenges, operational needs and priorities before we undertake any work.

added value

Value is about more than just cost. Our value comes from scoping engagements accurately, our detailed reports, providing your team with post-test support, the expert knowledge we impart and by going above & beyond the tick box deliverables used by other information security providers.
