CREST Approved Penetration Testing

What is CREST?

CREST is a not-for-profit accreditation and certification body that represents and supports the technical information security market. CREST was set up in 2006 in response to the clear need for more regulated professional services with known, dependable quality, and is now recognized globally as the cyber assurance body for the technical security industry.

CREST has become the respected standard for penetration testing in countries across the world, where it is increasingly a mandatory requirement for companies that have the most stringent security requirements such as government and financial services.

iSTORM are provided with information on the target systems, full permissions, log in credentials and IP ranges/URL’s.

This is designed to identify the majority of vulnerabilities. The benefit is that time/cost are reduced, as the tester is provided with everything they need to provide a full assessment.

iSTORM would be given no information on the target and would need to start from scratch with discovery and reconnaissance to identify and navigate the clients networks and applications.

This takes more time, and therefore cost, but it does give a clearer view on your security and sophistication levels.

A combination of White/Black box testing, performed with limited information about the internal functionality of the system.

You may want us to test your overall network with full disclosure but look at some applications with no starting information. This will be a tailored offering to you, based on your drivers and goals.

Often delivered over a period of months, this is the real life hack simulation. A strategic approach is used to identify issues and to test your ability to detect and respond to an attack.

We progress from reconnaissance, through gaining a network foothold, moving laterally to the valuable information, and simulated exfiltration.
