Cyber Essentials for professional firms

Legal, accountancy and other professional firms hold exactly what attackers want: sensitive client data, money movement, and a reputation that depends on trust. Clients, insurers and tender processes increasingly expect firms to prove they take security seriously—and Cyber Essentials has become the recognised way to do it. The good news is that for a well-managed firm, certification is more achievable than most partners expect.

What Cyber Essentials actually is

Cyber Essentials is a UK Government-backed certification scheme, overseen by the National Cyber Security Centre (NCSC), built around five practical technical controls: firewalls, secure configuration, security update management, user access control, and malware protection [1]. It's deliberately proportionate—these are the controls that stop the large majority of common, opportunistic attacks, not an enterprise-grade compliance marathon. Cyber Essentials is self-assessed and verified; Cyber Essentials Plus adds a hands-on technical audit by an assessor [2].

Why it matters for a professional firm

• It's a credible signal to clients. Breaches remain common—around four in ten UK businesses reported a cyber breach or attack in the last 12 months [3]—so demonstrable security is a genuine differentiator, not a box-tick.
• It's increasingly required. Many tenders, frameworks and professional bodies expect Cyber Essentials, and cyber insurers frequently ask about the same controls when pricing or approving cover [2].
• It's a proportionate baseline. The five controls give partners a clear, defensible standard to hold the firm—and its IT provider—to, without needing to become security experts themselves.

Why it's easier when your platform is managed well

Most of the Cyber Essentials controls are things a well-run Business Technology Platform already does: devices patched and configured to a standard, two-step sign-in enforced, access reviewed as people join and leave, and malware protection in place. When security is built into the platform rather than bolted on before an audit, certification becomes a natural outcome of good management—an annual confirmation of how you already work, not a once-a-year scramble.

That's how we approach it: prepare the firm properly, close any gaps against the five controls, and support you through assessment—so the certificate reflects a genuinely secure firm, and stays true between renewals.
