Comprehensive audit of firewalls, access controls, encryption standards, and vulnerability management across your entire network.
Regularly auditing your network security is essential for protecting your business against evolving cyber threats. This comprehensive checklist enables UK businesses to systematically review their firewalls, access controls, encryption standards, and vulnerability management processes. It provides a structured approach to identifying weaknesses before they can be exploited, helping you maintain a robust security posture across your entire network infrastructure.
Network administrators, IT security officers, and managed service providers responsible for maintaining network security at UK businesses.
Most UK SMEs run a full network security audit annually, with lighter reviews quarterly, and after any significant infrastructure change such as a new firewall or office move. Businesses handling sensitive data or working toward Cyber Essentials Plus often audit more frequently.
A thorough audit reviews firewall rules for redundancy, access controls across users and devices, encryption standards for data in transit and at rest, patch and vulnerability management, wireless security settings, and network segmentation. Each area should produce specific, actionable findings, not just a pass or fail.
Costs vary widely by network size and depth, but a small business external audit typically runs from around £500 to £2,500, while larger or more technical assessments can cost several thousand pounds. A self-guided checklist is a useful lower-cost starting point between formal audits.
Work through each section, firewall, access control, encryption, patching, wireless, and segmentation, recording findings and assigning an owner to fix any gaps found. This checklist gives a structured baseline so results can be compared consistently across repeat audits.
