All legacy methods of antivirus protection are now considered obsolete—they’re no longer an effective way to protect against current and future threats.
What Is Legacy Antivirus Protection?
When we talk about legacy antivirus, we’re talking about its underlying functionality.
Legacy antivirus is what’s called signature-based.
Think of a signature like a fingerprint. Each threat has its own fingerprint, or signature. The antivirus software stores these signatures in a database. Then, as the program scans the database, it compares them with the signatures housed on each workstation. Any signatures that match between the database and the workstation are considered a threat.
This type of protection worked well for years, up until recently.
That’s because the biggest limitation of signature-based antivirus software is the threat—whether it’s ransomware, malware, etc.—must take down at least one workstation within an organization before it can be added to the database and recognized as a threat.
The Next Generation of Antivirus is Endpoint Detection & Response
The evolution of antivirus software is EDR.
Endpoint detection and response helps protect against common threats, such as ransomware and malware.
EDR is deployed on workstations and servers. It collects information from those devices (endpoints) and sends them to a vendor or local server, which then identifies any changes in behavior.
How Does EDR Work?
Instead of signatures, EDR is based on artificial intelligence (AI). The AI detects unusual behavior and responds automatically to the threat without the need for a human to intervene.
Unlike legacy antivirus, EDR doesn’t require that a workstation goes down before it takes action.
For the best protection against cybersecurity threats, EDR is where your business needs to head if you’re still using legacy antivirus.
What Happens If EDR Detects A Threat?
EDR immediately kills and quarantines the threat
Security team receives real-time notification
Security team can then remediate, roll-back, or mark the threat "False Positive"
You remain protected throughout the process
In many cases we see in the headlines, EDR could’ve helped prevent these types of incidents.
EDR is a key factor in keeping your organization secure, but it’s not the only one.
