When does a business need a cyber security consultancy?
Most organisations know cyber security matters. Fewer know where they actually stand. They have antivirus, a firewall and an IT provider, and assume that’s enough, until a client sends a security questionnaire, a regulator asks questions or someone in accounts clicks the wrong link.
A cyber security consultancy gives you an independent view of your risks and a clear plan to deal with them. Here’s what that involves and when it’s worth bringing one in.
What a cyber security consultancy does
It’s different from your IT support. An IT provider keeps systems running day to day. A consultancy looks at the bigger picture: where your real risks are, whether your controls work, how you’d respond to an incident and what you need to meet standards or contractual requirements.
Typical work includes:
- Risk assessments and security reviews
- Gap analysis against frameworks such as Cyber Essentials, ISO 27001 or the Cyber Assessment Framework
- Writing and reviewing security policies
- Incident response planning and testing
- Data protection and UK GDPR compliance
- Staff awareness training
Signs you need outside help
A client or tender asks for it. Security questionnaires and certification requirements are now standard in many supply chains, particularly in the public sector, legal and financial services.
You’re in a regulated or critical sector. Organisations in energy, water, transport and aviation are increasingly expected to show how they meet the Cyber Assessment Framework. That’s a detailed, outcome-based assessment, and most internal teams benefit from specialist support.
You’ve had an incident, or a near miss. A phishing email that almost worked, or a laptop that went missing, is a good prompt to check what else could go wrong.
Nobody owns security. In many small and mid-sized businesses, security sits with whoever is most technical. That usually means it gets squeezed by other priorities.
A practical example
Imagine a 40-person law firm in London. It has a managed IT provider and Microsoft 365, and staff work in the office and at home. A new corporate client asks it to evidence its security controls before sending work.
A consultancy would start with a review: who has access to what, how devices are protected, whether multi-factor authentication is switched on everywhere and how client data is handled. The outcome is a short list of priorities, often a route to Cyber Essentials, updated policies and staff training on phishing and secure working. Most of it isn’t expensive. It just needs someone to own it and see it through. [Illustrative example.]
Common mistakes
- Treating certification as a one-off tick-box exercise
- Buying tools before understanding the risks they’re meant to address
- Having no tested incident response plan
- Forgetting people. Most breaches still start with a human, not a hacked server
