WHO WE HELP / PROFESSIONAL SERVICES
Cyber Essentials and assurance services for professional services firms.
Law firms, accountancy practices, financial services businesses, and management consultancies handle sensitive client data under contractual, regulatory, and professional obligations. We help you achieve and maintain the certification that clients, insurers, and regulators increasingly expect.
THE CHALLENGE
Professional services firms face a distinct set of cyber pressures.
Unlike organisations whose primary cyber risk is operational downtime, professional services businesses carry a dual liability. A successful attack exposes both their own infrastructure and the confidential data of the clients who trusted them with it. That creates regulatory, contractual, and reputational consequences that are proportionally more severe.
At the same time, most professional services firms are not large enough to maintain a dedicated internal security function. Certification and assurance work typically falls to an IT manager, a practice director, or a compliance lead who already carries a full workload. We provide the specialist expertise to take that burden off your team and support certification with a structured readiness-first approach.
COMMON TRIGGER SCENARIOS
Why professional services firms come to us.
Client contractual requirement
A corporate client, insurer, or enterprise customer has stipulated Cyber Essentials or equivalent as a condition of contract. You need certification before the renewal date.
Tender or panel requirement
You are bidding for a framework, legal panel, or advisory mandate where Cyber Essentials is listed as a mandatory or scored criterion.
Professional indemnity or cyber insurance
Your insurer has asked for evidence of baseline cyber controls as a condition of cover, or your renewal premium has increased following a claims event.
Regulatory or SRA/FCA expectation
Your regulator has published guidance on cyber resilience, or a client audit has highlighted gaps in your security posture that need addressing before the next review.
WHY IT MATTERS
What certification means in practice for your firm.
Client data is the target
Professional services firms hold commercially sensitive, legally privileged, and personally identifiable information. That makes them a high-value target for ransomware, phishing, and business email compromise — and a liability risk for the clients who shared it.
Contractual exposure is growing
Enterprise clients are increasingly embedding cyber certification requirements into supply chain contracts. Failure to certify before renewal can result in contract loss. Cyber Essentials is the minimum baseline most clients accept.
Regulatory expectations are rising
The SRA, FCA, and ICO have all published guidance or enforcement activity relating to cyber controls. Certification does not guarantee compliance, but it demonstrates a structured, evidenced approach to baseline security — which regulators take account of.
Certification is verifiable
Unlike a self-declaration, Cyber Essentials certification is independently issued and publicly searchable on the IASME registry. That transparency matters when clients, insurers, or regulators want to verify your controls rather than rely on your word.
