What is Endpoint Detection and Response (EDR)?
focuses on protecting endpoint devices, which are any hardware with network connections. Endpoints can be anything from laptops and desktop computers to smartphones, tablets, servers, and other Internet of Things (IoT) gadgets.
EDR is a development of conventional endpoint protection (EPP), a threat detection method based on classification. Due to the limitations of classification-based detection, endpoint solutions that rely on it can only identify known threats by searching an existing database. Because of this, these EDR systems may compare monitored behavior to a list of known risks and, if a match is found, automatically take action.
With a stronger emphasis on active monitoring and the capacity to spot unusual or suspect activity—which may go beyond recognized threats—and react appropriately, the current EDR genuinely stands out from the competition. An active block, isolating a host, or elevating results for additional investigation are a few examples of steps that might be implemented. In striking contrast to classification-based detection, which relies on prior knowledge or awareness of threats, this adds a layer of intelligence to the system.
The detection and identification of unknown dangers, such as advanced persistent threats (APTs), are thus better suited to EDR. APTs are, as their name suggests, more advanced cyber threats that have an extended detection window.
Benefits of EDR
EDR is a desirable security technology due to a variety of advantages. Given that endpoints account for 70% of all breaches, it provides visibility into endpoint behavior, making this strategy extremely useful for security experts.
The main goal of EDR is to examine a variety of data. As a result, risks like file-less malware attacks that would have eluded detection by traditional EPP platforms can now be found. EDR can also be integrated into a more extensive solution, such as a security information and event management (SIEM) platform, just like other tools.
But the amount of data that can be analyzed is constrained by the limiting focus on endpoint telemetry alone. Abnormal endpoint activity alone presents an incomplete picture. It’s more difficult to distinguish between a true threat and a false positive without context from what’s happening, for instance, on the network or in the cloud.
Extended Detection and Response (XDR)
The idea of XDR was born out of the realization that the infrastructure of an organization cannot be viewed via a single lens with the coverage and visibility necessary to reduce the threat surface. Endpoint, network, cloud, and employee-related compromises are all possible.
EDR and some conventional MDR products are generally considered to be constrained point solutions that only handle a specific aspect of a network. By combining detection and response capabilities for endpoints, networks, and cloud services in a single platform, XDR is a direct reaction to these restrictions. Because XDR is frequently provided as software-as-a-service (SaaS), enterprises can more efficiently utilize this technology.
XDR solutions claim to deliver pertinent information and threat data so organizations may better secure their data and operations in light of hybrid work environments, complicated IT architecture, and increasingly advanced attacks.
Benefits of XDR
Endpoint detection alone does not provide adequate protection for contemporary IT infrastructure, according to XDR solutions. Compromise indicators don’t just appear at the endpoints; they might also include unusual network traffic, unusual cloud activities, and unusual traffic patterns.
XDR provides a range of benefits for organizations:
Improved detection and response—as we’ve shown, XDR can assist companies in identifying and addressing threats aimed at any part of their IT infrastructure due to its focus on the entire threat surface.
All threat data is centralized on a single dashboard, which makes it simpler for teams to prioritize their response. This is one of the main selling features of XDR solutions.
The lower total cost of ownership: XDR solutions can make security toolkits simpler, which frequently aids organizations in finding efficiencies and utilizing their resources to the fullest.
Automated analytics is a major asset for security teams everywhere. Having a solution that will recognize, classify, and prioritize risks on your behalf while also analyzing reams of data.
By combining several pieces of technology, XDR adopts a comprehensive approach to cyber threat monitoring that provides better insight into an IT environment, yet even this strategy has limitations.
Managed Detection and Response (MDR)?
EDR and XDR can be beneficial for an organization, but they are not without difficulties. Tools that merely compile activity data—whether it comes from endpoints or other components of your IT infrastructure—generate a vast amount of information that needs further analysis. As a result, workloads rise and a thorough grasp of cybersecurity telemetry and operations is needed. The problem that controlled detection and response aims to solve is this one.
The benefits of EDR and/or XDR are packaged into a useful offering by MDR, a managed service that takes some of the burdens off of finding cybersecurity experts with the background necessary to develop an internal security program.
As we’ve mentioned, EDR and XDR produce a huge amount of data, necessitating teams to analyze larger volumes of alert data to distinguish between false positives and genuine threats. MDR relieves a client of this burden by delegating detection and response duties to a skilled outside security supplier.
MDR frequently merely provides a services-based solution to conventional detection and response activities. To further safeguard contemporary IT infrastructure, it is occasionally sold in packages with a variety of different security solutions, such as a DNS firewall, network sensors, or cloud monitoring.
Benefits of MDR
The peace of mind that MDR provides businesses with is its main advantage. MDR, which is a managed service, gives IT and security teams more time to concentrate on tactical projects that advance corporate objectives.
A managed solution may also be more affordable and available than creating an internal security staff. MDR providers can give their clients extra advantages by taking EDR capabilities and delivering them as managed services:
Event analysis—handling the difficult task of analyzing potentially billions of security events, aiding in the separation of false positives from real threats, frequently by combining human analysis and support with machine learning.
Alert triage enables organizations to better prioritize their cybersecurity efforts and center attention on the most pressing problems first.
In order to reduce an organization’s threat surface, vulnerability management involves proactively resolving vulnerabilities.
Remediation—offered as an extra service or covered by the service contract, MDR providers can assist with cybersecurity incident repair, restoration, and remediation, minimizing damage and recovery time.
Threat hunting: MDR service providers can keep an eye on a company’s network for any ongoing issues, assisting in the early detection of threats and limiting potential damage.
A Cybersecurity Solution’s Qualities to Search For
Due to the frequent use of these three terms, businesses looking for a solution are frequently left trying to determine what protections vendors will offer. They also support the notion that a single solution can address all security issues. However, you won’t find the ideal answer in an abbreviation.
However, concentrate on the outputs your company needs. This contains information on the breadth of coverage each solution offers, as well as the knowledge, credentials, and services provided by the solution provider. You require protection that covers every component of your IT infrastructure and provides timely, accurate information as well as the context necessary to make decisions about your security posture.
The best strategy to attain that degree of coverage necessitates carefully engineered technology. Look for a single solution that will enable you to streamline your security tech stack while providing the visibility you require rather than stacking various solutions on top of one another. In order to eliminate silos and improve your protection, seek out a comprehensive cybersecurity solution.
Conclusion
Overall, threat detection and response capabilities are offered in varied degrees by MDR, XDR, and EDR solutions. MDR offers round-the-clock monitoring and response, XDR broadens the reach to include numerous security domains, and EDR specializes in endpoint security.
By effectively identifying and responding to threats, reducing the impact of possible breaches, and boosting overall security resilience, these solutions assist organizations in enhancing their cybersecurity posture.
