ITHC Approved

An ITHC, or IT Health Check, is an IT security assessment that’s part of the compliance process for many government computer systems in the UK. 

Generally performed by an external service provider, an ITHC touches on both applications and infrastructure and involves an element of penetration testing. 

This accreditation is essential for any company wishing to supply services to public sector organisations via the Public Service Network.

By meeting these requirements and more, E-Sign is able to supply our digital solutions on the PSN, making us the only e-signature on the market with the ability to do so.
