Indelible Data Limited

Indelible Data Limited is a UK-based information security and technology consultancy founded in 2009. The company operates as a Cyber Essentials Certification Body, authorised to assess organisations against both the Basic and Plus levels of the UK Government-backed Cyber Essentials Scheme. It has issued over 2,500 certificates under this scheme, working with clients ranging from small businesses to major international banks and global technology corporations. Beyond certification, the company provides enterprise security architecture, security project management, training, and auditing services, with particular experience handling sensitive data where confidentiality, integrity, and availability are critical. Services include Cyber Essentials assessment and pre-assessment support, ISO 27001 audit and ISMS implementation, risk assessment and triage, vulnerability analysis and management, business continuity and disaster recovery planning, telecommunications and network security, and legal and regulatory compliance support. The company also trains Accredited Cyber Essentials (ACE) Practitioners on behalf of QG Management Standards and maintains a network of over 100 independent ACE Practitioners across the UK who can assist organisations with implementing technical controls, since the certification body itself does not directly implement these controls for clients it assesses. Sector experience includes financial services, nuclear supply chain, software houses, market research firms, publishing houses, and online/mail order retailers, often involving PCI DSS compliance, vulnerability triage across large server estates, and information security policy development.
