I chose SelfDefenseCamp because I needed a program that wasn't just theory, but simulated exactly what happens when an attacker tries to break into the network. After the first month, we tested targeted phishing scenarios and exploitation of vulnerabilities in Linux server configuration. My team managed to identify and block data exfiltration attempts, and the final report clearly highlighted what needs to be adjusted in the access policy. I didn't just receive a certificate, but a concrete remediation plan that I applied immediately. The only thing I would improve would be more exercises with real reaction time, but for a start, it was exactly what I needed.
