Passive vs. Active Antivirus: Choosing the Right Protection

Compare periodic scanning with real-time prevention, EDR monitoring, investigation, and response.

Part of the Cybersecurity Learning Center

Passive scanning looks for known threats during scheduled or manual checks. Active protection monitors activity in real time and may block, isolate, or investigate suspicious behavior.

Why it matters

What business leaders should understand

Business endpoints need continuous protection and accountable response. Running multiple competing security products can also create conflicts, so the design should be deliberate.

The right response should reflect your environment, data, vendors, risk, and operational priorities. Use this guide as a practical starting point, then validate important decisions with the people responsible for your technology, cybersecurity, legal obligations, and insurance coverage.
