AV vs. NGAV vs. EDR: What’s the Difference?
A phishing email you open contains malware. But you’re not worried because your IT team installed antivirus software on all your organization’s computers.
Unfortunately, traditional antivirus (AV) software might not be enough to protect your organization.
Security in 2026 requires a layered approach that addresses different kinds of attacks. Modern attacks often aren’t just a malicious file; they can be a script or a stolen login that traditional antivirus misses.
You need next-generation antivirus software (NGAV) and endpoint detection and response (EDR) to fill in the gaps that traditional antivirus doesn’t cover.
Let’s examine the differences between the three security tools to help you understand why investing in just one leaves your organization vulnerable to today’s threats.
AV (Traditional Antivirus)
This is what most people think of when they hear the term “antivirus.” You probably had a family computer that had Norton or McAfee software. If you downloaded a malicious file, you could generally count on antivirus to alert you and stop it.
Goal: Stop known malware.
- Effective against previously identified threats
- Limited visibility into behavior
- Struggles with fileless or new attacks
Approach: “Have we seen this before?”
The problem? Malware is constantly evolving, and new variants are always being introduced. Traditional antivirus can’t stop malware it hasn’t seen before.
NGAV (Next-generation Antivirus)
This is where next-generation antivirus steps in. It functions similarly to traditional antivirus, but it also can stop new and unidentified threats.
Goal: Stop known and unknown malware.
- Behavior-based detection
- Machine learning models to improve discovery
- Better at catching new or fileless threats
AV, NGAV and EDR are essential tools for any organization, as no target — regardless of size — is off-limits. In fact, many attackers target small businesses because they often lack proper security systems.
Approach: “Does this behavior look malicious?”
Between AV and NGAV handling both known and unknown threats, you may think you have all your bases covered. Think again.
What happens if malware slips by both security tools? You need a tool that can limit the burn radius, so your whole organization doesn’t go down in flames.
EDR (Endpoint Detection and Response)
Endpoint detection and response continuously watches your devices in real time, looking for unusual behavior that could be a threat. It doesn’t stop threats like AV and NGAV do, but it responds to real-time threats by containing and mitigating the damage.
Goal: Detect and respond when something slips through.
- Continuous monitoring of endpoint activity
- Identifies suspicious activity chains over time
- Supports investigation and remediation
Approach: “If something bad runs, how quickly can we detect and contain it?”
EDR is the safety net for everything. No tool is 100% secure, but EDR can significantly reduce the damage from an attack.
So, to summarize:
- AV = known threats
- NGAV = known and unknown threats
- EDR = assumes prevention can fail and focuses on detection and response
Protect Your Organization’s Devices
AV, NGAV and EDR are essential tools for any organization, as no target — regardless of size — is off-limits. In fact, many attackers target small businesses because they often lack proper security systems.
