Managed EDR Stay secure with your endpoints using innovative EDR and MDR services from Security Information and Event Management (SIEM). Learn about the difference between EDR and SIEM solutions.
EDR tools are technology platforms that alert IT teams of suspicious activity and record device data to analyze attack patterns. Managed EDR services combine leading EDR technologies with expert threat-hunting and investigation services for optimal protection from threats in off-hour environments.
Detecting Threats in Real-Time
Detection is the foundation of enterprise security. EDR solutions work by continuously monitoring endpoint devices and collecting telemetry data, sending it back to a centralized hub where security analysts can analyze it in real time. Security analysts then compare endpoint behavior against established baselines, spot anomalies, and create statistical models which predict normal endpoint activity patterns; some EDR solutions even leverage threat intelligence feeds for added context by comparing network activity against known examples of cyberattacks.
Once an alert is generated, solutions may isolate the affected device or network segment to protect other devices from attack – this process is known as containment. For IT and security teams, it’s crucial that compromised devices can be isolated so they can further investigate them using forensic capabilities – for example, by discovering what files it compromised, where it entered the system, or how it gained access to authentication credentials.
Most EDR solutions feature a central user console where IT and security teams can receive alerts, review device logs, initiate response workflows, generate reports, and visualize critical information comprehensively through data dashboards. Some solutions also incorporate automation features that enable them to automatically collect, process, and perform incident response tasks, allowing IT staff to focus on more challenging tasks.
Traditional endpoint protection solutions like antivirus software do not detect advanced threats that evade perimeter defenses and make their way inside, such as stealthy attacks that roam for months in your network without being detected – often gathering vulnerabilities and data before launching ransomware attacks or zero-day exploits. Managed EDR tools can detect these hidden threats so you can contain and neutralize them effectively.
An EDR solution should be able to track all activity on your network, including processes created, drivers loaded, registry changes, disk access, memory access, and network connections. Some EDR tools use machine learning or AI techniques to detect threats based on this behavior – alerting users if patterns emerge – while others use threat intelligence feeds as context – real-world examples of cyberattacks provide data against which your endpoint behavior can be measured.
Finally, the top EDR tools provide response capabilities that enable operators to deal effectively with active incidents during an active incident. This may involve disconnecting or stopping compromised processes, notifying users and information security teams, isolating or disabling suspect endpoints or accounts, alerting security teams when suspicious activity is suspected, and collecting artifacts during investigations. Some also support forensic capabilities for further analysis during their investigations.
Many organizations prefer having a security vendor or partner manage their EDR (also called managed EDR). This approach offers numerous advantages, such as faster detection and response times.
Endpoint detection and response solutions should identify files exhibiting ransomware-like behavior, alerting you when this has happened before so you can quickly address threats and minimize damages. EDR tools can also contain threats and reduce damages to protect clients’ data.
Many organizations rely on segmentation to thwart advanced threats from spreading laterally across their networks. Still, an EDR solution should detect and isolate potential attacks before they have time to penetrate your security measures.
When selecting an EDR solution, look for one with Gartner-leading technology and experienced security professionals on board to protect your business. ClearNetwork uses managed CrowdStrike technology with 20 years of experience defending customers – an option you can rely on!
An effective EDR solution should also allow for events and insights to be uploaded securely into a central repository, enabling your team to perform investigations and response actions easily. Cross-endpoint correlation should also be considered to gain the most accurate view of your threat environment; Bitdefender GravityZone XDR takes this one step further by collecting insights and suspicious event details directly from each EDR agent deployed on endpoints and securely sending them over to its GravityZone Control Center for analysis.
Detecting Other Threats
Once threats bypass traditional endpoint security tools, they may remain dormant for months while gathering intelligence for an attack – gathering vulnerabilities for ransomware attacks or cyberattacks of various sorts. Managed EDR uses continuous real-time monitoring, threat detection analytics, and automated response capabilities to detect and stop these advanced threats before they strike again.
Anton Chuvakin, of Gartner analyst, coined the term “endpoint detection and response” (EDR) in 2013 to refer to emerging security systems that monitor and analyze suspicious activities on hosts and endpoints such as desktop/laptop computers, servers, mobile devices, and IoT devices. EDR software collects telemetry data from these endpoints to use machine learning algorithms and other analytic technologies to detect threats using machine learning, detect known or suspected malware threats, and take preemptive actions to reduce damage or stop damage before it happens.
EDR solutions differ from other tools by employing a combination of heuristics, analytics, and automation to detect threats instead of solely relying on signature databases and signature matching for detection purposes. This increases productivity while decreasing the time from discovering an incident until its resolution.
EDR systems can be deployed and managed externally by managed security service providers or cybersecurity partners (also referred to as managed EDR). This differs from traditional endpoint protection platforms and antivirus, which typically are deployed and administered internally or through third-party vendors.
