EDR, or endpoint detection and response, and antivirus software are both important tools for protecting a company’s systems from cyber threats. However, there are some key differences between the two that businesses should understand in order to choose the right security solution for their needs.

Antivirus Software

At a high level, an antivirus is a software program that is designed to protect a computer or other device from malware, which is short for malicious software. Malware includes viruses, worms, Trojans, and other harmful programs that can cause damage to a device or steal sensitive information. 

Antivirus programs work by scanning a device for potential threats and then removing or quarantining any malware that is found. Some antivirus programs also have additional features, such as firewalls and web filtering, to provide even more protection.

Endpoint Detection and Response

EDR, on the other hand, is a more advanced security solution that is used to detect and respond to potential threats on a device or network. EDR systems typically consist of software that is installed on individual devices, such as computers or mobile phones, and is designed to monitor the device for suspicious activity. 

When a potential threat is detected, the EDR software can take a number of different actions, such as quarantining the threat, alerting the user or network administrator, or blocking the threat from spreading to other devices. In addition to detection and response capabilities, EDR systems often also have other features, such as the ability to investigate past events and provide detailed reports on security incidents.

The Differences Between EDR and Antivirus

One of the key differences between EDR and antivirus software is the level of visibility and control that they provide. Antivirus software is focused primarily on detecting and removing malware, but it typically does not provide visibility into the broader activity on a system. This means that it can miss other types of threats, such as malicious insiders or advanced persistent threats (APTs).

While EDR, provides much more visibility and control over the endpoint devices in a company’s network. It allows security teams to see what is happening on the endpoint in real-time, and to take immediate action to prevent or mitigate threats. This can include blocking network connections, terminating processes, and even quarantining an entire device if necessary.

Another key difference between EDR and antivirus software is the level of automation and integration that they offer. Antivirus software is typically a standalone solution that is not integrated with other security tools or systems. This can make it difficult to manage and coordinate across a company’s entire security infrastructure.

EDR, on the other hand, is designed to be integrated with other security tools and systems, such as SIEMs, firewalls, and intrusion prevention systems (IPS). This allows security teams to see a complete picture of the activity on a company’s network, and to coordinate their response to threats across multiple systems. This level of integration and automation can greatly improve a company’s ability to detect and respond to threats.

In summary, the main difference between EDR and antivirus software is the level of visibility and control that they provide. Antivirus software is focused on detecting and removing malware, but does not provide the same level of visibility and control as EDR. EDR, on the other hand, provides a more comprehensive view of the activity on a company’s network, and allows security teams to take immediate action to prevent or mitigate threats. This can make EDR a more effective solution for protecting a business from a wider range of cyber threats.
