What is EDR, and why isn't your antivirus software enough anymore?
For years, antivirus software was synonymous with cybersecurity. Installing antivirus software on every computer was considered “securing” the system. But the threat landscape has changed radically, and what worked five years ago now leaves companies completely exposed.
This article explains what EDR (Endpoint Detection and Response) is, how it differs from traditional antivirus software, and why any company with more than 20 employees in Latin America should consider this technology an essential component of its security strategy.
Traditional Antivirus: What It Does and Where It Falls Short
Conventional antivirus software uses a signature-based detection model. It maintains a database of known threats—viruses, Trojans, worms—and compares every file that runs on the system against that database. If there is a match, it blocks it.
The problem is that this model assumes that threats are known in advance. And in 2026, they are not. Attackers use polymorphic malware that changes its code with each execution, fileless scripts that operate in memory without leaving a trace on disk, and “living-off-the-land” techniques that use legitimate operating system tools to carry out malicious actions. None of these techniques will be detected by signature-based antivirus software.
Furthermore, the antivirus operates reactively: it only takes action when it detects something it already recognizes. It does not analyze behavior, does not correlate events across multiple endpoints, and does not provide investigation or automated response capabilities.
EDR: Endpoint Detection and Response
EDR is a category of security technology designed to continuously monitor endpoints—laptops, workstations, servers, and mobile devices—and detect suspicious activity in real time, even when it does not match any known signature.
Instead of searching for specific malicious files, EDR analyzes the behavior of processes, network connections, changes to the system registry, and user actions. If a legitimate process such as PowerShell begins executing unusual commands, encrypting files on a large scale, or communicating with unknown external servers, EDR detects it, isolates it, and alerts the security team—all within seconds.
Key Differences Between Antivirus and EDR
Detection model: The antivirus uses static signatures. EDR uses behavioral analysis, machine learning, and real-time threat intelligence.
Scope of visibility: Antivirus software detects individual files. EDR detects the entire attack chain: from the point of entry to lateral movement and data exfiltration.
Response Capabilities: Antivirus software blocks or quarantines a file. EDR can isolate an entire device from the network, terminate malicious processes, roll back changes, and generate a detailed forensic report.
Research: Antivirus software does not provide context. EDR logs all endpoint activity, allowing analysts to reconstruct exactly what happened, how the threat entered the system, and which systems were affected.
Threat coverage: Antivirus software does not detect fileless attacks, “living-off-the-land” attacks, or next-generation ransomware. EDR does.
Why EDR Is Especially Relevant for Latin America
Organizations in Latin America face a volume of attacks that is significantly higher than the global average. With an average of more than 2,700 attacks per week per organization and a 259% increase in ransomware, relying on traditional antivirus software is like locking the door but leaving all the windows open.
In addition, many companies in the region operate with small IT teams that cannot dedicate analysts to monitor security alerts 24 hours a day. Modern EDR solutions—especially when managed through a security-as-a-service provider—include automated response capabilities that do not require human intervention for the most common threats, and scale up to specialized analysts when the situation calls for it.
EDR isn't the destination—it's the starting point
It’s important to understand that EDR is a fundamental layer of protection, but it’s not the only one. A comprehensive security strategy combines EDR with email protection, identity management, DNS filtering, network monitoring, and ongoing staff training. But if your company currently only has antivirus software, EDR is the most important first step you can take.
