CTAS accredited

We were selected as one of the first companies to provide the CESG Tailored Assurance Service (CTAS), a service from CESG intended for a wide range of IT products and systems.

How does it work?

The purpose of CTAS is to provide answers to assurance questions and concerns from accreditors, which are usually from the pre-deployment stage. A tailored evaluation is then conducted and key results that may impact business are highlighted.
