For years, antivirus was the standard approach to Cybersecurity.
Install it. Keep it updated. Stay protected.
But cyber threats have changed dramatically — and traditional antivirus hasn’t kept pace.
Today’s attackers use ransomware, identity compromise, session hijacking and fileless malware specifically designed to avoid signature-based detection.
That means businesses relying solely on antivirus are often operating with a false sense of security.
What traditional antivirus actually does
Traditional antivirus focuses on identifying known malicious files by:
- Comparing files against known malware signatures
- Blocking recognised threats
- Scanning devices periodically
And this still has value in a modern business. But it’s only reactive to already-known dangers.
If malware is new, modified or behaving differently, antivirus may not recognise it at all, which is the problem…
Modern attacks don’t behave like traditional malware
In recent years, attackers’ strategies have evolved, increasingly using:
- Legitimate credentials
- Stolen session tokens
- Script-based attacks
- Living-off-the-land techniques
- Ransomware variants that mutate constantly
Many of these attacks never trigger antivirus alerts, which means attackers can remain undetected while moving through systems, escalating privileges and preparing larger attacks. All of which has meant more and more forward-thinking businesses have started to adopt EDR.
What Is EDR?
EDR stands for Endpoint Detection & Response.
Instead of simply scanning files, EDR continuously monitors device activity and behaviour to identify suspicious patterns like:
- Unusual PowerShell activity
- Credential abuse
- Privilege escalation
- Persistence mechanisms
- Lateral movement between systems
Most importantly, EDR enables active response; isolating compromised devices before threats spread which helps to protect critical data and stop ransomware attacks from locking users out of their computers.
Why 24/7 SOC Monitoring matters
In short, technology alone isn’t enough.
EDR tools generate large amounts of data and alerts. Without experienced analysts reviewing them, important threats can still be missed.
That’s why managed SOC monitoring like Huntress EDR and ITDR is essential, offering:
- 24/7 human-led monitoring
- Threat investigation
- Ransomware detection and isolation
- Persistent foothold detection
- Microsoft 365 identity threat monitoring
This combination of technology – plus human expertise – dramatically improves threat detection and response.
The shift SMBs need to make
Antivirus is no longer the golden shield it once was. Now, it one layer within a wider security strategy with modern SMB protection requiring:
- Antivirus
- EDR
- Identity monitoring
- Human-led threat hunting
- Security awareness training
Today’s attacks are designed to bypass traditional controls so if you’ve got this far, the one thing that you should take away is that the question you should stop asking yourself is:
“Do we have antivirus?”
And should now be:
“What happens when something gets past it?”
