One Smart Question: Why are Detection Tools Alone No Longer Enough to Stop Advanced Cyber Threats?

After decades of reliance, detection tools are no longer enough. Tools like endpoint detection and response (EDR), antivirus, and others raise an alarm when suspicious activity is detected. That said, detection is just the first step. The cyber threat landscape is constantly evolving and adversaries are getting more sophisticated and stealthy, making investigation an imperative component of the cybersecurity process. Threat investigation helps security teams understand the full context of a threat, providing the tools needed to remove adversaries from networks faster by decreasing mean time to knowledge (MTTK). Understanding the threat helps teams respond with precision, hunt proactively, and determine root causes, not just chase down alerts. Detection is essential, but it is just a signal. Investigation goes beyond detection, helping security teams understand threats and turn defenses into resilience.
