Cyber Essentials Plus is a UK government-backed certification that shows a business has basic security measures in place to defend against common cyber threats. It requires both a self-assessment questionnaire and an external vulnerability scan carried out by an accredited certification body. Many organizations find it useful for building trust with clients and meeting supply chain security requirements, though it does demand ongoing effort to maintain compliance.
