Understanding XDR vs EDR in cybersecurity. With the current rise in home and remote working practices, especially due to the COVID-19 pandemic restrictions, cybersecurity has become a major concern for every individual and organization. A large number of cyberattacks occurs at the endpoint. Such attacks begin on a single machine and then spread across the entire network from there.

To keep up with today’s scattered workforce and the 70 percent of all breaches that still come from the endpoint, IT professionals need to be more proactive and much more capable of remediating cyber threats remotely.

Understanding what each solution has to offer is sometimes the hardest challenge, especially when terminology varies from vendor to vendor. EDR and XDR are two of the most popular IT security solutions used today. In this post, we look at both solutions to determine how each works and which is the better option.

Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR) solutions are meant to deliver real-time threat detection and prevention by leveraging data visibility, data analytics, and threat intelligence.

EDR was designed to protect a system’s network from all angles. With this strategy, an attack’s major component, the endpoints, was fully covered. In the end, this resulted in proactive endpoint protection, which covered several security blind spots and gaps.

However, effective EDR utilization involves coordination with other technologies and procedures. It can’t safeguard your system on its own, but it can help. It’s also not able to give you a complete picture of your system. An attacker’s actions on your endpoints can be seen, but only to a limited extent. You will need to use more detection and monitoring tools together with EDR to help you determine what happened during the attack.

XDR was created to fill the information void left by EDR. In contrast to EDR, it can provide visibility into all stages of a cyber-exploit, from endpoint all the way to payload. By incorporating XDR with your security framework, you can gather information from several platforms. This allows you to get a more accurate view of previous attacks and current ones if any.

This is certainly helpful as networks become more dispersed and more third-party services are integrated into the system and given access privileges.

Let’s look at what each of the two security options does:

Endpoint Detection and Response (EDR):

Endpoint detection and response (EDR) systems are intended to provide cutting-edge security for corporate endpoints.

These systems offer multi-layered, completely integrated endpoint security. EDR uses a combination of real-time monitoring and data analytics to detect risks and enables fast remediation of discovered risks through automated, rule-driven responses.

The primary purpose of an EDR system is to provide comprehensive visibility into a specific endpoint. This visibility is used by EDR’s automatic response capabilities to mitigate threats, avert attacks, and assist proactive threat hunting efforts. The fundamental goal of EDR is to facilitate the transition from traditional, reactive defense to preventive threat management.

Extended Detection and Response (XDR):

While endpoints are a big target for cybercriminals and must be protected, they are only one component of an organization’s IT infrastructure. A corporate network is made up of multiple types of systems. Using point solutions to handle a heterogeneous network environment can be complex and overwhelming for security teams.

The Extended Detection and Response (XDR) protocol is intended to make enterprise network security administration easier.

XDR solutions extend security visibility over an organization’s complete architecture, including endpoints, cloud platform, portable devices, and much more. This centralized visibility and administration simplifies security management and the implementation of standard security rules across the company.

An XDR solution’s major focus is security integration. The XDR solution provides the context necessary to detect complex and dispersed assaults by aggregating data from all over the company.

XDR solutions can also use predictive analytics and threat intelligence to discover trends and known dangers in these data sets. Finally, security aggregation reduces the workload of cybersecurity experts, allowing them to focus their efforts more effectively. XDR solutions can also respond to recognized risks automatically.

This involves taking proactive actions to prevent harmful content from entering a system as well as trying to mitigate an ongoing assault on an exploited endpoint.

EDR Versus XDR

Both EDR and XDR approaches are intended to replace traditional, reactive approaches to data and system security.

As a result, EDR and XDR solutions share several similarities including the following:

  • Both have a preventive approach. Traditional security solutions are frequently focused on detecting and remediating ongoing attacks. EDR and XDR try to avoid security issues by gathering detailed data and utilizing predictive analytics and threat intelligence to detect risks before they happen.
  • In both EDR and XDR, threat detection is automated, and responses are based on the results of that detection. These tools allow businesses and other organizations to avoid or quickly remediate an attack in order to reduce the cost and impact of a cyberattack on them.
  • A threat hunter’s job is to find and remedy potential security flaws before an attacker may exploit them. As a result of EDR and XDR, security professionals have simple access to data and a high level of visibility.

Despite their commonalities, EDR and XDR approach cybersecurity differently.

There are certain key differences between the two, including:

  • Point of Focus: EDR focuses on safeguarding the endpoint by offering deep visibility and threat avoidance. XDR takes a broader view of security, incorporating it into endpoints, cloud technology, email, and many other applications.
  • Integration: Organizations may be able to manually connect EDR solutions with a variety of point solutions to provide “best in breed” protection for endpoints. As a combined visibility and threat management system, XDR drastically simplifies an organization’s security operations.

Why Extended Detection and Response (XDR) is the Better Option

For endpoint detection and response, XDR offers a more advanced, holistic method that’s also cross-platform compatible.

Instead of collecting and correlating data from various endpoint devices, XDR analyzes data from a wide range of sources including endpoints, cloud workloads, networks, SIEM, servers, and more. All of the different tools and threat routes can be shown in one go from a single platform.

With XDR, workflow efficiency is enhanced by pre-tuned detection algorithms across multiple products and systems.
