Why we picked it The best free way to actually feel the attack: PortSwigger's free labs let you break into other users' data in a safe practice app. Working through horizontal escalation (reaching a peer's records) and vertical escalation (reaching admin functions) teaches you precisely what to test in your own product. It turns the abstract advice into muscle memory.
