Why Antivirus Alone Is No Longer Enough

For years, traditional antivirus software was considered a sufficient baseline for endpoint security. Today’s threat landscape has changed dramatically. Modern attacks are stealthier, faster, and designed specifically to evade signature-based detection.

The Limitations of Traditional Antivirus

Antivirus tools primarily rely on known signatures and basic heuristics. While still useful for blocking common malware, they often fail to detect:

• Fileless attacks and living-off-the-land techniques
• Credential theft and lateral movement
• Ransomware that encrypts data before detection
• Zero-day exploits with no known signatures

What EDR Adds to the Equation

Endpoint Detection and Response (EDR) focuses on continuous monitoring and behavioral analysis. Instead of just blocking known threats, EDR platforms observe how systems behave and respond when activity looks suspicious.

EDR provides visibility into what happened, how it happened, and what needs to be done to contain it.

How We Protect Clients with SentinelOne Complete

At Exodo IT, we deploy SentinelOne Complete across managed environments. This platform combines AI-driven detection with automated response capabilities to stop threats in real time.

• Behavior-based AI detection that doesn’t rely on signatures
• Automatic threat isolation and remediation
• Ransomware rollback and recovery capabilities
• Full endpoint activity visibility for investigation and response

Why This Matters for Businesses

Downtime, data loss, and regulatory exposure can all result from a single successful endpoint compromise. EDR dramatically reduces the dwell time of threats and helps prevent minor incidents from becoming major outages.

Antivirus is still part of the security stack—but it should no longer be the only line of defense.
