Twelve services, from a single vulnerability scan to round-the-clock monitoring, each with a clear starting price and a fixed written quote before we begin.
Vulnerability scanning
Automated scanning of your internet-facing systems for known weaknesses, missing patches and misconfigurations, checked by a person before it reaches you.
From £195 per scan, excl. taxes
Web application & API penetration testing
A hands-on test of your website, customer portal or API, following the OWASP Top 10 and OWASP API Security Top 10, by a tester who thinks like an attacker.
From £1,450 per test, excl. taxes
Network penetration testing
External testing of your firewall, VPN and exposed services, and internal testing that shows what an attacker could reach from one compromised laptop.
From £970 per test, excl. taxes
Wireless security assessment
On-site testing of your Wi-Fi: encryption, guest network separation, rogue access points and how far your signal leaks outside the building.
From £595 per site, excl. taxes
Microsoft 365 & cloud security review
Most small-business breaches start with a mailbox.
From £695 per review, excl. taxes
Cyber Essentials readiness
We get you ready to pass Cyber Essentials or Cyber Essentials Plus first time, the certification many UK customers, insurers and public-sector contracts require.
From £395 per organisation, excl. taxes
UK GDPR & ISO 27001 readiness
A clear picture of where you stand against UK GDPR security requirements or ISO 27001, and a prioritised plan to close the gaps.
From £935 per assessment, excl. taxes
Managed endpoint protection
Next-generation antivirus and endpoint detection installed, configured and watched for you, so threats are stopped and investigated without your team chasing alerts.
From £9 per device / month, excl. taxes
24/7 security monitoring
Round-the-clock monitoring of your endpoints, Microsoft 365 and firewall logs, with analysts who investigate alerts and act on real threats day or night.
From £485 per month, excl. taxes
Security awareness & phishing simulation
People are the most common way in.

No jargon and no surprises. You know what we are testing, why, and what it will cost before we start.
Assess
We learn how your business runs and what matters most, then agree scope and rules of engagement in writing.
Test & harden
We test, monitor and review against that scope, and rank every finding by real-world risk.
Report
You get a plain-English summary for leadership and technical detail your IT team can act on.
Support
We help you fix what we found, retest to confirm, and stay on hand for whatever comes next.

Frequently asked questions
Is there a minimum contract?
Monthly plans run for 12 months, then roll monthly with 30 days' notice. One-off tests and assessments have no contract.
Why are your prices lower than larger firms?
We keep overheads low, use automation for the repetitive work, and spend our testers' time on the findings that matter. You pay for skilled people, not a big office.
Do you fix the problems you find?
Yes. Every report includes step-by-step fixes, and we can carry out the work for you or guide your IT provider. Retesting fixed issues is included.
Will testing disrupt my business?
Tests follow written rules of engagement agreed with you. Anything that could affect live services is scheduled out of hours, and we stop at once if you ask.
Do you work with our existing IT provider?
Yes. Most of our clients already have an IT provider; we work alongside them and give them clear, actionable reports.
How quickly can you start?
Vulnerability scans and Microsoft 365 reviews can usually start within a week. Penetration tests are typically booked two to three weeks ahead.
