EDR vs Antivirus: What Actually Protects Corporate Devices in 2025
May 26, 2025 · 9 min read · System Networks
In 2024, 68% of successful corporate attacks used zero-day exploits or fileless techniques that classic antivirus cannot detect. EDR (Endpoint Detection & Response) is the next generation of endpoint protection — monitoring behaviour rather than comparing against signature databases.
Antivirus vs EDR Comparison
| Parameter | Antivirus | EDR |
|---|---|---|
| Detection method | Signatures of known threats | Behaviour analysis of processes and files |
| Zero-day threats | Cannot detect | Detects via anomalous behaviour |
| Incident response | Delete/quarantine | Isolate device, collect artefacts, investigate |
| Analyst visibility | No telemetry | Full history of processes, network connections, file operations |
| Device load | Low | Medium (agent continuously collects data) |
| Cost | ₽500–₽2,000/device/yr | ₽3,000–₽12,000/device/yr |
When Antivirus Is Enough, When EDR Is Needed
Antivirus sufficient if:
- ✓Under 25 devices
- ✓No high-value confidential data
- ✓No admin privileges for end users
- ✓No FSTEC/CII monitoring requirements
EDR needed if:
- →CII subject or 152-FZ personal data processing
- →More than 50 devices in infrastructure
- →Previous malware incidents
- →Need incident investigation and forensics
- →Operating a SOC or SIEM
