Expression of interest

The first step in any application is sending us an expression of interest in membership. You can click the Enquire Today button right to begin that journey.

We will then ask you to sign a mutual Non-Disclosure Agreement (NDA). Once an NDA has been signed, we will provide you with login details to our Membership Portal.

In the portal you will find the company membership application form. This is a comprehensive form requiring a prospective member company to provide evidence that they are compliant with the various requirements.


Each discipline has its own separate application form where we will review specific methodologies for delivering the service you are applying for.

Prospective member companies can apply for membership in:

• Penetration Testing
• Vulnerability Assessment
• Intelligence-Led Penetration Testing (CREST STAR)
• Threat Intelligence
• Cyber Security Incident Response
