Don't forget browser plugins, which IASME have also confirmed as being in scope.
- Network Security Enhancements: Firewalls and secure configuration settings are strictly defined. The 2025 document continues to promote this.
- Data Protection Measures: Encryption of sensitive data, both at rest and in transit, is still required.

Failing to meet these new standards can have serious consequences. Cyber attacks can lead to financial loss, reputational damage, and legal penalties. On the other hand, certification can open doors to new contracts, especially in the UK government supply chain.
Here’s why you should prioritise these updates:
- Win More Contracts: Many public and private sector clients require Cyber Essentials certification.
