Is Offensive Security Keeping Up with the Latest Cyber Attacks?
Security is not a point-in-time exercise. It’s a cycle of testing, fixing, and starting over. Organisations that treat it as anything less quickly fall behind. In the last decade, we’ve seen how offensive security practices such as penetration testing, combined with follow-up patching and mitigation strategies, have significantly strengthened defences. For instance, Active Directory hardening,…
