For years, antivirus software has been the main tool for protecting our devices, detecting and blocking known viruses thanks to a list of signatures. But in the face of modern, complex attacks, although still essential, antivirus is showing its limitations. On its own, it cannot protect against attacks, particularly advanced zero-day attacks (i.e., those for which there has been no publication or known patch).
Think of the EDR as a fire extinguisher that contains the flames on the spot.
The BDU’s role: reacting
Constant monitoring and advanced detection: EDR tracks the activity of every device in real time, thanks to sophisticated algorithms capable of detecting both known and unknown threats.
Unlike conventional antivirus software, which only recognizes and blocks attacks that have already been catalogued, EDR identifies and neutralizes new threats such as ransomware, unauthorized access attempts or files behaving suspiciously, enabling problems to be identified and dealt with quickly.
Rapid reaction: if a threat is detected, the EDR can take immediate action to limit the damage. It can block malicious activity, isolate the infected device to protect the rest of the network, and send alerts to security teams.
Post-incident analysis: after an attack, EDR provides detailed information for autonomous adaptation and improvement. It also enables IT teams to understand why a threat was blocked or not. These same teams can then manually modify certain parameters to prevent a second attempt.
An indispensable tool for today and tomorrow
EDR is not just a security tool, it’s proactive protection against modern threats. It helps companies secure their devices, react quickly to incidents and prepare for the future.
