What are EDR and NDR and what are their benefits?


NDR (network detection and response) and EDR (endpoint detection and response) are two similar yet distinctly different approaches to cyber security. As the rate of cyber security incidents increases each year, savvy business owners and IT administrators are looking for newer and more intelligent ways of fending off these threats in order to keep their business running at full operational capacity.

Traditional anti-virus software is still effective and plays an integral role in protecting your business from malware, ransomware, and other cyber security incidents, but they are no longer enough to serve as the sole defense mechanism. NDR and EDR are two of many cyber security solutions that present themselves as two effective and important solutions which use machine learning and artificial intelligence to defend against a newer and more deadly wave of cyber threats but understanding exactly how to utilize them for your business in specific isn’t always so straightforward.

How do you know which solution your business needs, and what are their advantages?

What is NDR?

NDR – Network Detection and Response is a type of cyber security solution your business can put into place to detect any suspicious or unusual traffic passing through your network. NDR software will constantly analyze traffic data in order to construct a norm that helps it understand the network’s usual behavior. This is a crucial step as with this information, and anomalies can be easily identified and honed in on.

From this point on, a notification is sent to the network administrators, who can then take the necessary steps and actions to eliminate the threat if need be. Alternatively, automated solutions and other cyber security systems can step up to isolate, contain, and eliminate the threat.

Advantages of NDR

Including an NDR solution into your cyber security system is a great step forward for your business and offers several key benefits:

  • NDR offers great protection against new and evolving malware strains
  • Uses AI to combat ‘weaponized AI’ and more malicious cyber security threats that are developing each and every day to find new weaknesses and loopholes in cyber security systems
  • Provides forensic analyses to help determine how threats entered the network in the first place, helping ensure it does not happen again
  • Helps streamline incident response and threat hunting processes
  • NDR is great at detecting malware through a network. While an EDR solution could not identify these threats, as they are not part of the organizations network, an NDR solution can act swiftly and effectively through the use of AI and advanced technology.

What is EDR?

EDR – Endpoint Detection and Response shares some similarities with NDR but is fundamentally different in nature. EDR solutions focus on scouring and monitoring all endpoints connected to your business network. An EDR solution will monitor and collect these endpoints like an NDR, constructing a “normal” behavior pattern that then helps identify threats within an instant. Also, like NDR solutions, the EDR software will then identify network administrators of a threat or act to immediately contain and eliminate it.

EDR solutions are becoming adopted by more and more businesses each year. In fact, according to McAfee, there is a yearly growth rate of nearly 26% in the usage of EDR solutions. This is driven by several reasons, but primarily the increase in the number of endpoints connected to business networks. Historically, the only devices connected to a business network would be work computers, printers, and other stationary devices. But now, each employee and any that visit the business premises and connect to the network have a host of mobile devices, tablets, laptops, IoT devices, and more that rely on the interconnectedness of the modern world.

While this is a huge advantage when it comes to streamlining business operations and processes, as is seen in their ballooning popularity and widespread adoption, it also opens a huge number of weak points in a business’s security. In short, with more endpoints comes more vulnerabilities. Every endpoint connected to your network is a potential route in for malware and cyber security threats.

Advantages of EDR

No antivirus software can ever be 100% effective, as new strains are being released each and every day. One of the best methods of prevention is to plug or protect the source – i.e., the endpoints.

EDR software, therefore, has several key benefits:

  • EDR acts as the second line of defense after anti-virus software
  • EDR software uses AI to constantly become more effective in identifying new and more malicious strains of malware
  • Is great at identifying threats via endpoints themselves, potentially before they spread through the network.

Should I be using EDR or NDR solutions?

Really, there is no correct answer here. .

Businesses will find value in either of the solutions alone, but those who truly care about protecting their business from cyber security incidents should be looking into holistic strategies which incorporate not just one but both EDR and NDR solutions. The reason for this is that cyber security threats come in a wide range of shapes and forms, and one single solution will not be enough to prevent every single type of threat from potentially grinding your business operations to a halt.

You should be looking for an NDR solution that provides visibility over the entirety of your network. Since many businesses are turning towards cloud-based services, this is of utmost importance – and you need to make sure that the NDR solution is completely compatible with all cloud services you are using.

With regards to EDR solutions, find one that works together well with your other cyber security solutions. Forward thinking businesses who are prepared for even the most difficult of cyber security incidents have one thing in common: a series of solutions that work seamlessly in tandem to cover all weak points.
