Cyber Security Assessment

Think you're secure? Let's find out...

It’s tough to know where your weak spots are until something breaks. But the best security leaders don’t wait for that to happen. They don’t just assume they’re safe; they validate it.

Our Cyber Security Assessment gives you the intelligence and clarity to do exactly that. From simulating real-world attacks to analysing your infrastructure’s resilience, we expose hidden risks and help you build a stronger, more responsive security posture.

If you're serious about being secure, start by knowing exactly where you stand.

FAQs

A Cyber Security Assessment is like a full-system health check for your organisation’s digital defences. It examines how well your infrastructure, processes, and people can withstand and recover from cyber threats. Through a combination of penetration testing, infrastructure analysis, and consultative workshops, the assessment identifies vulnerabilities and provides a prioritised, actionable remediation plan, so you know exactly where you stand and what to fix first.

A Cyber Security Assessment gives you a clear picture of your actual risk exposure, helping you stop threats before they start. It also supports compliance, reduces the chance of operational disruption, and provides valuable insights that help you make smarter, more strategic security decisions. Simply put, it’s a practical way to protect your business and maximise ROI on your security investments.

External infrastructure testing shows you exactly what a cyber criminal would see when scanning your systems from the outside. Think of it as a ‘hacker’s-eye view’, but with no real damage. This testing uncovers exposed services, weak configurations, or unpatched systems that could be exploited in a real attack. By identifying these entry points early, you can harden your perimeter and stay one step ahead of external threats.

If your business relies on machinery, industrial controls, or any form of physical automation, an Operational Technology (OT) network assessment is essential. It focuses on securing the technology that powers your day-to-day operations, like production lines, utilities, or building systems. These environments often have unique risks and legacy systems that can’t be treated like traditional IT. An OT assessment helps you spot those vulnerabilities, protect critical operations, and maintain safety and uptime across your infrastructure.

Not at all. We know uptime matters, so the assessment is designed to be non-intrusive and conducted with minimal impact on your daily operations. We’ll work closely with your team to plan each phase to ensure all testing is controlled, scoped, and tailored around your environment’s sensitivity. No surprises, no downtime, just valuable insight, delivered responsibly.

You’ll receive a clear, structured report that outlines your key risks, ranked by priority, with step-by-step recommendations on how to close the gaps. We’ll walk you through it so there’s no ambiguity. Whether you’re strengthening defences, improving compliance, or planning investments, the insights help guide your next steps with confidence.
