Cost of Cybersecurity Audit
across the UK

How much does a cybersecurity audit cost in the UK?

Cybersecurity audit costs in the UK typically range from £1,500 to £15,000+ depending on business size and complexity. Small businesses may pay £1,500–£3,500, whilst medium enterprises expect £5,000–£10,000. Large organisations with complex infrastructure often invest £10,000–£25,000 or more for comprehensive assessments.

What factors affect the price of a cybersecurity audit?

Cybersecurity audit pricing depends on organisation size, IT infrastructure complexity, number of systems to assess, regulatory compliance requirements (GDPR, PCI-DSS), and the audit scope depth. Additional factors include whether penetration testing is included, staff numbers, remote versus on-site assessment, and the auditor's certifications and experience level.

What does a cybersecurity audit actually include?

A cybersecurity audit typically includes network vulnerability scanning, firewall and access control review, password policy assessment, malware detection testing, data protection evaluation, and staff security awareness checking. Reports outline identified risks, severity ratings, and remediation recommendations with timelines for implementation and compliance verification.

What's the difference between a cybersecurity audit and a penetration test?

A cybersecurity audit is a comprehensive review of security policies, systems, and controls to identify weaknesses and compliance gaps. A penetration test actively attempts to exploit vulnerabilities to assess real-world impact. Audits are broader and policy-focused; penetration tests are hands-on attack simulations requiring explicit authorisation.

What should I check before hiring a cybersecurity audit provider?

Verify auditors hold CREST, CISSP, or GPEN certifications and are accredited by relevant bodies like ISOIEC 27001 assessment partners. Request previous client references, check insurance coverage, confirm their experience with your industry, and ensure they follow BS 7799 or ISO 27035 standards for incident response.

How long does a cybersecurity audit take and when will I get results?

A typical cybersecurity audit takes two to six weeks depending on organisation size and complexity. Initial assessment lasts one to two weeks, followed by analysis and testing phases. You'll receive a detailed written report within one to two weeks of completion, with an executive summary and implementation roadmap included.

Should I use a local or national cybersecurity audit provider in the UK?

Cybersecurity audits are largely unregulated, so choose providers based on credentials and expertise rather than location. National firms often offer broader compliance knowledge and industry-specific experience. Local providers may offer better communication and follow-up support, but verify CREST accreditation and relevant certifications regardless of size or location.
