Traditional anti-virus was designed for a world of known malware and scheduled scans. Attackers stopped operating that way years ago. Here is the difference, line by line.

Managed EDRTraditional anti-virus
Roll devices back to their pre-infection state, giving you freedom from ransomware.Cannot roll back to a pre-infection state, which increases your ransomware risk.
Uses artificial intelligence to detect and prevent current and emerging threats, with continual platform updates.Uses signatures to identify threats, so capability lags behind the latest attacker techniques.
Automated system remediation for fast incident response.Manual investigation of endpoint health, then manual remediation of misconfigurations and unwanted changes.
Monitors processes before, during and after execution, so new threats cannot slip through.Blind during execution, which leaves an entry point for a capable attacker.
Monitors your systems in real time.Relies on daily or weekly scans, increasing the window of exposure.
Keeps devices fast through continual lightweight monitoring.Long scans that slow the machine down while they run.

Hybrid work widened the attack surface. It improves flexibility and work-life balance, but every home network and personal device is now part of your risk profile. Protecting your people, your customers and your reputation means monitoring endpoints wherever they are — not only the ones inside the office.
