How EDR Works: A Guide to EDR Security?


The global interconnectivity and usage of the internet and cloud services have resulted in an increasing rate of cybersecurity risks. The sophisticated techniques of cybercriminals and businesses’ lack of resources make the latter more vulnerable to data breaches.

To ensure customer data protection while leveraging new technology, you need an intelligent security solution like endpoint detection and response. It can mitigate unauthorized access and discourage theft of intellectual property.

However, business leaders should note that they cannot rely on traditional cybersecurity solutions alone. Antivirus software and firewalls are a thing of the past, and cybercriminals are getting smarter by the day. Cybercriminals have become more resilient and prepared to tackle your organization’s defenses.

This article will talk about how EDR works and what it is.

How EDR Works?

EDR Definition

EDR solutions are security tools that proactively monitor and detect potential attacks on devices connected to your network. This new technology lets you have a complete picture of all the activities on your endpoints. This level of visibility aids you in examining threats and addressing breaches.

EDR software can keep an eye on your devices and quickly respond to malicious behaviors running on your system. It is equipped with multiple functionalities such as data exploration, threat hunting, forensic investigation, alerts prioritization, and other response features to thwart attacks.

The three primary duties of EDR security software are:

1. Data Gathering

– Information is gathered from endpoint devices, including communications, process executions, and user logins.

2. Data Recording

– Logs all data concerning security incidents in real-time.

3. Detection

– EDR analyzes behaviors. It will determine if activities are within normal range or anomalies present in the network.

These three tasks are continuously carried out to ensure real-time visibility and response. As threats get detected, the security solution makes automatic responses and alerts security teams.

You can combine your EDR security software with an Endpoint Protection Platform or EPP to have even more extensive coverage. The latter is designed to fend off malware and prevent malicious activity on your network.

While EDR is proactive, EPP is preventive. Combining their powers enable you to protect and respond to network threats more thoroughly.

Importance of EDR Security

How Does an EDR Work? It monitors all endpoints connected to your corporate network proactively. It constantly sifts through your data, searching for threats and initiating responses.

Using EDR technology can provide several benefits to your organization. Here are some of them.

End-to-end Visibility is Maintained

EDR solutions keep track of all devices, hunting down any suspicious movements on the network. They collect information from endpoints and use this to stop threats and assess previous and ongoing attacks.

Detecting Zero-day Threats

Legacy tools like antivirus software and firewalls can detect known threats through signature-based detection. On the other hand, EDR tools can actively look for unknown threats to stop the spread of advanced attacks. It uses behavioral analysis powered by artificial intelligence to reduce the chances of data compromise.

Quick Incident Response

How EDR works takes a lot of explanation, but you should know that this software effectively contains threats before delving into that. It isolates affected endpoints and responds to events quickly. An initial automated response is vital in preventing an event from ballooning.

Cyber Forensics

EDR security software has forensic functionalities to collect data, generate reports, and analyze them to get ahead of new and emerging threats.

How does EDR Works?

EDR security solutions use different methods to perform real-time visibility and start proactive detection and response. Here’s how EDR works, step-by-step.

After installing EDR technology, advanced algorithms will examine the behaviors of individual users on the system. The EDR tool may feel if something is off about a particular behavior as it sees their activities. An investigation will occur if it senses an odd behavior on a given user.

The collected data is filtered and monitored to look for malicious behavior. If malicious activity is found, the algorithm searches the path of the attack and builds it back to know the point of entry.

After which, it consolidates all data points into smaller categories so that analysts can review them quickly. Should there be a legitimate hit, the customer is notified. They will receive recommended steps to take for further investigation and advanced forensics. However, if it is a false positive, the alert is closed, and investigation notes are included. They won’t notify the customers anymore.

After reading this post, we hope you’ve been enlightened about how EDR works. Implementing it on your network will undoubtedly be a big help, so don’t wait any further. Contact us today to find out how Comodo can secure your network and help you maintain uptime.
