Cybersecurity Resilience: NetWitness EDR vs Open Source EDR Solutions

  • by NetWitness

Cybersecurity is one of the most prominent issues facing organizations today. After all the hard work it took to build your company from the ground up, it can seem like there is always a fight to protect it. Cyber threats can damage your organization’s reputation and put client information at risk. For this reason, you invest in the best security technologies. However, in order to leverage your technologies for maximum security, you need to first understand what those benefits are. 

If you’ve recently ventured into the world of endpoint detection and response, NetWitness is here to provide you with the ultimate guide. If you would like to understand what EDR is, the benefits of the technology, and how to leverage it for better business practices, you’ve come to the right place. 

What Is EDR?

Endpoint detection and response, better known as EDR, is a cybersecurity technology that protects IT systems like PCs and servers.  It can analyze data in real time and provide continuous threat detection. EDRs are known to be effective and dependable because they are able to detect and respond to threats that you might miss with centralized solutions like SIEM or network tools.  When used together, however, unrivaled visibility is achieved.

Endpoint detection and response work by monitoring activity on all the devices on a network. When it detects a cyber threat like malware, it takes the appropriate action to contain and eliminate the threat. With the help of other security solutions like antiviruses and firewalls, endpoint detection software can enhance a network’s security capabilities. 

The “open” in open source EDR refers to the fact that it is distributed with a source code that makes it available to use and modify with all its original rights. In comparison, proprietary EDR software requires companies to obtain a commercial license. It is copyrighted technology and typically not available for free use. 

Types of EDRs

While it may seem like all EDRs do the same thing, there are slight differences when it comes to what they can do. 

Signature-based EDR- This type of endpoint detection can catch previously seen malware. When it spots these types of malware, it raises an alert so the threat can be addressed immediately. 

Heuristics-based EDR-  Heuristics-based EDR solutions are generally used in addition to signature-based EDRs. They examine code with the goal of detecting suspicious activity that may indicate a virus is present. 

Machine learning-based EDR- The machine learning-based can determine how severe a threat is and analyze it accordingly. These EDR solutions can determine what normal behavior looks like on a network so it does not raise unnecessary red flags. This is done through different algorithms. 

Benefits of Endpoint Detection and Response

Endpoint detection and response software are beneficial for several reasons. Here are a few.

Improved Security

A significant benefit of endpoint detection is that it enhances network security. EDR solutions provide information that is useful in identifying potential threats. Only the most critical data is provided so that threats can be handled quickly. This allows network security teams to conduct productive investigations.  

With the help of endpoint detection software, security teams can be more efficient. This technology automates tasks and places data in an area that allows multiple teams to have access to it. Because of this, communication is made more accessible across security teams. 

Providing Ongoing Security

EDR solutions are constantly detecting and reacting to cyber threats in real-time. This constant monitoring reduces the risks of security breaches and other threats. Ongoing security makes it easy to identify issues before they occur. When problems arise, security teams can quickly point out which part of the network is the source of the problem. 

All in all, the endpoint detection and response software strengthens the security of the organization. When security teams are given the ability to be proactive, organizations are put at a lesser risk for more serious cyber attacks. 

Detecting All Endpoint Threats

EDR solutions detect all endpoint threats, no matter how minor they may seem. The EDR software detects things that the naked eye may look past. This type of accuracy is one of the main benefits of endpoint detection and response technologies.

Organizations can quickly identify and communicate threats with EDR technology. They search for outside threats and track suspicious activity within the network. For large organizations, this is especially beneficial because, otherwise, it would be challenging to keep such a keen eye on user activity. 

Reduced False Positives

Your EDR software will conduct its own investigation before alerting the security team. It will comb through the details of the suspicious activity and will only alert the security team for serious issues. This will take some stress off your security team’s shoulders and save them some time investigating benign threats. 

If the EDR solution finds that a flagged event is not a threat after all, the investigation is closed, and the security team will not have to worry about it.


Having a strong infrastructure costs organizations less in the long run. This is because it is cheaper to be proactive than to clean up the mess after an attack. 

With the help of EDR software, the workload of the security team is lessened. This gives them more time to manage less mundane tasks.

How Do Open Source EDR Solutions Differ From NetWitness’s Proprietary EDR?

NetWitness Endpoint is unlike any other software on the market. While many antivirus solutions also detect malware, they are substantially different from our EDR design, which is optimized for the threat detection, investigation, and response use case. Here are a few reasons why:

Robust Support for Troubleshooting:

One of the glaring distinctions between open source EDR solutions and NetWitness Endpoint is the level of support available. When you hit a roadblock with an open-source EDR solution, you may find yourself navigating the multitude of online forums in search of answers. This quest for solutions can be time-consuming and frustrating. 

In contrast, NetWitness Endpoint comes equipped with dedicated support teams that stand ready to assist you in troubleshooting and resolving issues promptly. This invaluable support infrastructure ensures that you’re never alone in your battle against cyber threats.
