Managed Offence Proactive Cybersecurity Testing

Effective cybersecurity isn’t just about defence — it’s also about challenging your systems to uncover weaknesses before someone else does. Our Managed Offence Service forms a core part of our Cybersecurity as a Service offering. Through regular, controlled offensive testing — including penetration testing, vulnerability assessments, and simulated attack techniques — our approach actively identifies weaknesses in your digital infrastructure, allowing you to strengthen your defences before malicious actors exploit them. By mimicking real-world attacker tactics, techniques, and procedures (TTPs), we provide actionable insights that improve your cyber resilience and reduce your risk profile.

Managed Offence Proactive Cybersecurity Testing

Penetration Testing by Certified Experts

Regular on-site visits ensure your network, servers, and infrastructure are kept secure and fully updated. Our engineers carry out patching, firmware updates, and essential checks that prevent future issues.

Attacker-Informed Techniques

Using the latest TTPs observed in the wild, we replicate adversary behaviour to test how well your current defences detect, block, and respond to advanced threats.

Clear, Actionable Reporting

We deliver concise, prioritised reports outlining vulnerabilities, their impact, and recommended remediations — so your team knows exactly what to fix and how to strengthen your security.

Continuous Improvement Model

This isn’t a one-off engagement — we perform regular offensive testing as part of a proactive cybersecurity strategy, ensuring your systems evolve to meet emerging threats.

Choosing Mustard IT for Managed Offence

Cyber threats are evolving faster than ever — and SMEs are increasingly in the crosshairs. Relying on passive defence alone leaves your business exposed to unseen vulnerabilities. Our Managed Offence Service flips the model: instead of waiting for a breach, we go looking for weaknesses first — using the same mindset and methods as real attackers. This enables you to harden your systems and close gaps before they become incidents.

Delivered by certified security professionals with real-world expertise, our offensive testing is safe, structured, and scalable to your risk profile. Whether you’re operating under compliance obligations or simply want assurance that your security is effective, we give you the insight — and the confidence — to act. As part of our Cybersecurity as a Service model, we work with you continuously to improve, not just react.
