Network detection and response (NDR) software documents a company’s network activity while automating threat remediation and reporting cyber threats to IT and security teams. NDR enables an organization to consolidate IT security services into one solution and simplifies network protection. NDR is critical because it provides an end-to-end view of network activity. For example, certain malicious activity may not be reflected in network logs but will be visible by network tools as soon as they interact with systems throughout the network.  Since NDR software uses artificial intelligence (AI) and machine learning (ML) to analyze network traffic, it is highly adept at detecting malicious behavior as well as reporting and remediating such activity in real time.  ### What are the Common Features of Network Detection and Response (NDR) System? NDR system usually includes the following: **AI and ML:** NDR uses AI and ML in its software solution. IT and security professionals can use the data to develop streamlined discovery and response workflows across an organization’s network. **Automated threat detection:** When traffic behavior deviates from normal functionality, an NDR solution detects the issue and automatically assists in an investigation. NDR software includes or integrates with other solutions that automate incident response processes to minimize the threat’s impact. ### What are the Benefits of Network Detection and Response (NDR)  Software? There are several benefits to using NDR software. **Automatically detects anomalies** : NDR software automatically detects anomalies in network traffic by applying non-signature-based detection techniques and using behavioral analytics, AI, and ML. **Monitors all traffic flows** : NDR solutions monitor all traffic entering or exiting the network so there is visibility to identify and mitigate security incidents, regardless of where a threat comes from. Giving this end-to-end view of the network offers IT and security teams greater visibility across the network to mitigate traffic threats. **Analyzes network in real time** : NDR analyzes an organization’s network for threats in real time or near real time. It provides timely alerts for IT and security teams, improving incident response times. **Narrows down incident response** : NDR solutions attribute malicious behavior to specific IP addresses and perform forensic analyses through AI and ML to determine how threats have moved across a network environment. This leads to faster, more efficient incident response.  **Who Uses Network Detection and Response (NDR) Software?** **Network IT and cybersecurity staff:** These workers use NDR software to observe network traffic and detect anomalies related to user behavior. **Industries** : Organizations in all industries, especially technology or highly sensitive data-oriented sectors like financial services, seek NDR solutions to help protect their networks. ### What Are Alternatives to Network Detection and Response (NDR) Software? Network traffic analysis (NTA) software and endpoint detection response (EDR) software are alternatives to NDR software. [Network traffic analysis (NTA) software](https://www.g2.com/categories/network-traffic-analysis-nta): NTA software is similar to NDR tools in that it monitors network traffic and looks for suspicious activity while providing real-time analysis and alerting IT administrators. The main difference is that it also analyzes network performance and pinpoints reasons for slow downloads.  [Endpoint detection & response (EDR)](https://www.g2.com/categories/endpoint-detection-response-edr)[software](https://www.g2.com/categories/endpoint-detection-response-edr): EDR tools are similar to NDR solutions, focusing on network activity. It detects, investigates, and removes malicious software penetrating a network’s devices. These tools give greater visibility of a system’s overall health, including each specific device’s state. Companies use these tools to mitigate endpoint penetrations quickly and prevent data loss, theft, or system failures.  ### Challenges with Network Detection and Response (NDR) Software There are some challenges IT teams can encounter with NDR software. **Sophisticated hackers:** With high volumes of data traveling across an organization’s network, hackers create more sophisticated threats that can hide their tracks and avoid detection by blending in with traffic patterns. Attackers can also make threats move in small and infrequent batches to avoid detection. **Budget constraints:** As hackers become more sophisticated, organizations must keep their NDR solutions up-to-date to keep up with the latest threats. Budget constraints could prevent IT and security teams from doing so. ### How to Buy Network Detection and Response (NDR) Software #### Requirements Gathering (RFI/RFP) for Network Detection and Response (NDR) Software  If an organization is just starting and looking to purchase NDR software, G2 can help. The manual work necessary in security and compliance causes multiple pain points. If the company is large and has a lot of networks, data, or devices in its organization, it may need to shop for scalable NDR  solutions. Users should think about the pain points in their security to help create a checklist of criteria. Additionally, the buyer must determine the number of employees who will need to use this software and if they currently have the skills to administer it.  Taking a holistic overview of the business and identifying pain points can help the team springboard into creating a checklist of criteria. The list is a detailed guide that includes necessary and nice-to-have features, including budget features, number of users, integrations, security staff skills, cloud or on-premises solutions, and more. Depending on the deployment scope, producing an RFI, a one-page list with bullet points describing what is needed from NDR software, might be helpful. #### Compare Network Detection and Response (NDR) Software Products **Create a long list** Vendor evaluations are essential to the software buying process, from meeting the business functionality needs to implementation. For ease of comparison, after all demos are complete, it helps to prepare a consistent list of questions regarding specific needs and concerns to ask each vendor. **Create a short list** From the long list of vendors, it is helpful to narrow the list of vendors and come up with a shorter list of contenders, preferably no more than three to five. With this list, businesses can produce a matrix to compare the features and pricing of the various solutions. **Conduct demos** To ensure a comprehensive comparison, the user should demo each solution on the short list with the same use cases. This allows the business to evaluate like for like and see how each vendor stacks up against the competition.  #### Selection of Network Detection and Response (NDR) Software **Choose a selection team** Before getting started, creating a winning team that will work together throughout the process, from identifying pain points to implementation, is crucial. The selection team should include organization members with the right interests, skills, and participation time.  A good starting point is to aim for three to five people who fill roles such as the primary decision maker, project manager, process owner, system owner, or staffing subject matter expert, as well as a technical lead, head administrator, or security administrator. The vendor selection team in smaller companies may have fewer participants who will multitask and take on more responsibilities. **Compare notes** The selection team should compare notes, facts, and figures noted during the process, such as costs, security capabilities, and alert and incident response times. **Negotiation** Just because something is written on a company’s pricing page does not mean it's final. It is crucial to open up a conversation regarding pricing and licensing. For example, the vendor may be willing to give a discount for multi-year contracts or for recommending the product to others. **Final decision** After this stage, and before going all in, it is recommended to roll out a test run or pilot program to test adoption with a small sample size of users. If the tool is well used and received, the buyer can be confident that the selection was correct. If not, it might be time to return to the drawing board. ### What Does Network Detection and Response (NDR) Software Cost? NDR software is considered a long-term investment. This means there must be a careful evaluation of vendors, and the software should be tailored to each organization's specific requirements. Once NDR software is purchased, deployed, and integrated into an organization’s security system, the cost could be high, so the evaluation stage of selecting the right tool is crucial.  The chosen NDR vendor should continue to provide support for the platform with flexibility and open integration. Pricing can be pay-as-you-go, and costs may also vary depending on whether unified threat management is self-managed or fully managed. #### Return on Investment (ROI) As organizations consider recouping the money spent on the software, it is critical to understand the costs that will be saved in terms of efficiency. In the long run, the investment must be worth preventing downtime, loss of revenue, and any reputation damage that a security breach would cause.
