What's This Course About

Take your network defence skills to the next level with the Network Security Masterclass, an intensive 2-day programme covering the full lifecycle of securing modern networks. You will learn to analyse threats and map vulnerabilities across network infrastructure and Virtual Private Networks (VPNs), then apply practical hardening techniques to close the gaps you find. The course blends foundational concepts with hands-on practice so you can identify weak links and build resilient, defensible network architectures.

Beyond hardening, the masterclass shows you how to validate your defences through security testing and benchmarking, debug and troubleshoot security issues, and review logs for effective incident detection and response. By the end of the two days you will be able to assess a network's security posture, remediate weaknesses, measure the impact of your controls, and respond confidently when incidents occur.
