Cybersecurity professionals traditionally focus on defense, but relying solely on defensive tools like antivirus and firewalls is no longer sufficient as attackers grow more sophisticated. A combined offensive and defensive approach is recommended. Defense in depth adds layers of protection, but the real gap is detecting attackers already inside the network. Offensive techniques like threat hunting — proactively searching for hidden threats using human analysts rather than automation — and continuous education through CTF challenges and conferences are highlighted as key strategies to stay ahead of adversaries.
