Cyber Essentials certification in London at a glance
When a London supplier bids for public sector work or joins a corporate supply chain, Cyber Essentials is often the first security box on the form. It is a modest, practical scheme, and for small and mid-sized firms across the capital it is the usual starting point. Cyber Essentials covers five technical controls: firewalls, secure configuration, security update management, user access control and malware protection, with Cyber Essentials Plus adding hands-on technical testing. Sterling's London office prepares the controls, with Effivity and Sterling Academy included with the engagement; a licensed certification body marks the assessment. National law, regulators and accreditation detail sit on the United Kingdom page rather than here.

Cyber Essentials in London: questions clients ask
Why is Cyber Essentials popular with London SMEs?
It is affordable in effort, practical and widely recognised in supply chains. London SMEs meet it in public tenders and in questionnaires from larger customers, and the five controls are mostly things a well-run IT setup should already do. National procurement rules sit on the UK page.
Should a London firm choose Cyber Essentials or Cyber Essentials Plus?
Choose the level the buyer names. The basic scheme rests on a verified self-assessment, while Plus adds hands-on technical testing of the controls. Many firms take the basic level first and move to Plus when a contract or insurer asks for stronger proof.
