Choosing Mustard IT for Managed Defence

Cyberattacks don’t operate on a 9-to-5 schedule — and for many SMEs, internal resources simply can’t maintain constant vigilance. Our Managed Defence Service provides a critical safety net: an expert team monitoring your systems 24×7, ready to identify and respond to suspicious activity before it becomes a serious issue. You benefit from enterprise-grade threat detection and incident response, without the cost or complexity of running your own SOC.

Whether you’re concerned about ransomware, insider threats, or business email compromise, our service gives you the coverage and expertise to detect and contain threats early. When combined with our Managed Offence service, you gain a comprehensive, proactive cybersecurity strategy — one that defends, challenges, and improves your cyber posture continuously.
