PrimeSec does not hand you a pre-built machine. You get professional lab guides and build the environment yourself — that is where the skill comes from.

• Install a hypervisor and build your first VM
• Complete a Linux command line challenge set
• Inspect running services and close unnecessary ports
• Analyse a phishing email and its headers
• Harden a Windows VM against common attacks
• Configure and test a backup and restore

• A documented home security lab build
• A phishing analysis write-up
• A personal security hardening checklist with evidence
