An antivirus is a protection tool that is installed on computers to prevent it from being infected, in this case, before the computer is infected or to see if it is already infected, it validates against the signature database it contains to identify malware and be able to combat it. An EDR, on the other hand, is a detection and response tool that is installed on computers and that, instead of using a signature database as a reference, performs protection based on the behavior of the malicious agent. In this article we thoroughly analyze the figure of EDR and compare it with the antivirus that we already know.
An EDR is a tool designed to monitor, detect and respond to any suspicious activity on devices connected to a network, such as computers or servers. Unlike traditional antivirus, which is based on the detection of known malware signatures, EDR goes one step further. It not only identifies malware that is already known, but also detects unusual behavior that could indicate a threat not yet registered, and to do so it uses artificial intelligence, machine learning and advanced threat detection and response techniques to prevent malware from being executed. .
How does an EDR work?
The EDR is not only there watching. It also acts in real time to block possible threats. First, it collects information from all devices connected to the network, such as login activities, processes that are running, and even files that are opened. All of this information is continually analyzed to detect any activity that does not match normal patterns.
If the EDR detects something suspicious, it can make automatic decisions, such as isolating the compromised device from the rest of the network to prevent the spread of malware. This is something that a traditional antivirus simply cannot do as quickly and effectively.
Key differences between EDR and antivirus
Now, let’s talk about the clear differences between an EDR and the antivirus that you probably have installed on your computer. Traditional antivirus focuses on protecting you against known threats, such as viruses, worms or Trojans. It works by scanning files for malware signatures, meaning that if the virus has already been identified, the antivirus can stop it. But if it is a new or unknown threat, antivirus might not be enough.
The EDR, on the other hand, does not depend only on well-known signatures. Use machine learning to identify suspicious behavior patterns. This allows you to detect threats that have not yet been cataloged or that are hidden very well. Furthermore, EDR not only detects, but also responds automatically and in real time.
Which one should you use?
The short answer is: it depends on your needs. If you only use your computer to browse the Internet and check emails, an antivirus will probably be enough for you. However, if you have a company or handle sensitive information, such as financial or personal data, it is best to opt for an EDR system that provides you with a more advanced level of protection.
EDR gives you complete visibility into what’s happening on your network and gives you the ability to act quickly if something goes wrong. Even if malware does sneak in, EDR will detect it through its continuous behavioral analysis and take action to prevent the damage from spreading.
EDR is an evolution of traditional antivirus that responds to the growing sophistication of cyber attacks. While antivirus relies on stopping known threats, EDR is proactive, detecting suspicious behavior and responding in real time. If you handle critical information or simply want to be more protected, an EDR system is the best option to keep your devices safe in an increasingly complex digital world.
In the end, the decision depends on what you’re looking for: if you just want the basics, antivirus will have you covered. But if you are looking for a more complete solution that offers greater security and real-time visibility, EDR is the way to go.
