NTA Monitor is a certified CHECK Service Provider and a founder member of the scheme, maintaining the highest "green level" status.

IT health checks identify vulnerabilities in IT systems and networks which may compromise the confidentiality, integrity or availability of information held on that IT system. CESG traditionally provided IT health check services for HMG and the wider public sector of systems handling protectively marked information. Demand for these services has grown and therefore, in line with similar CESG initiatives, a special partnership with industry is the most appropriate way of meeting this demand.

Companies belonging to CHECK are measured against high standards set by CESG. Therefore, HMG and CNI customers can be assured that they will receive a high quality service if the work is carried out under the Terms & Conditions of CHECK.


NTA Monitor is a founder member and certified Service Provider of the scheme. CREST (Council of Registered Ethical Security Testers) is a standards-based organisation for penetration test suppliers incorporating a best practice technical certification programme for individual consultants. Additionally, CREST provides its members with a framework of guidance including standards, methodologies and recommendations aimed at ensuring the very highest standards of leading edge security testing.

Cyber Essentials

NTA Monitor is an approved Certifying Body under the Cyber Essentials scheme, allowing us to provide certification services to organisations wishing to achieve the Cyber Essentials standard. A primary objective of the UK Government’s National Cyber Security Strategy is to make the UK a safer place to conduct business online. To support this objective the Cyber Essentials scheme has been developed to assist organisations with defending against the most common form of basic cyber attacks originating from the Internet.

Certification allows an organisation to demonstrate that they have achieved a fundamental level of cyber security. For more information on Cyber Essentials please visit http://www.cyberessentials.org/


NTA Monitor is able to deliver a number of services relating to CLAS (CESG Listed Advisor Scheme), a partnership linking the unique Information Assurance knowledge of CESG with the expertise and resources of the private sector.

CLAS consultants are approved to provide Information Assurance advice on systems processing protectively marked information up to, and including, SECRET. Potential customers of the CLAS Scheme should also note that if the information is not protectively marked then they do not need to specify membership of CLAS in their invitations to tender, and may be challenged if equally competent non-scheme members are prevented from bidding.
