Endpoint Detection and Response Beyond Antivirus. Behavior-Based.
SOC-Monitored 24/7.

Antivirus compares files against a database of known malware signatures — it catches known threats. EDR monitors behavioral telemetry across every endpoint — what processes are running, what files are being modified, what network connections are being made, what registry keys are being touched — and detects anomalous behavior regardless of whether the threat has a known signature. EDR catches: ransomware before it completes encryption (behavioral pattern: rapid file modification); fileless malware that runs in memory through legitimate processes (no files to scan, but behavioral anomalies visible); credential dumping (LSASS memory access patterns); living-off-the-land attacks using Windows tools for malicious purposes; lateral movement between devices; and command-and-control communication. Beyond detection, EDR provides automated isolation (network-severs a compromised device immediately), forensic telemetry for investigation, and the alert pipeline that connects to a SOC for human review and response.

Microsoft Defender has improved significantly and provides a better baseline than older signature-only antivirus — it includes some behavioral detection through Microsoft Defender for Endpoint (the enterprise version). What it doesn't provide without active management: the SOC layer that reviews alerts and responds to them; behavioral tuning specific to your environment that reduces false positives and improves detection accuracy; threat hunting that proactively looks for indicators of compromise before an alert fires; and the forensic investigation capability that follows a confirmed incident. Defender running on defaults without a SOC reviewing its output generates alerts that go unreviewed. An enterprise EDR solution managed by Gradius with the SOC actively reviewing alerts delivers materially better protection outcomes — particularly for the ransomware and living-off-the-land attacks where behavioral tuning and human response make the critical difference.

When EDR detects a potential threat, the sequence is: the EDR agent generates an alert with behavioral telemetry — what process triggered the alert, what it was doing, what other processes it spawned, what files were modified, what network connections were made. For high-confidence threats (ransomware encryption behavior, credential dumping, confirmed malware execution), automated isolation can immediately sever the device's network connection before human review to prevent spread. A Gradius SOC analyst reviews the alert, evaluates severity and scope, confirms whether isolation has occurred or needs to be initiated, and begins remediation — cleaning the endpoint, identifying whether other devices show related indicators of compromise, and documenting the incident for insurance and compliance reporting. The business is notified of confirmed threats with a summary of what occurred and what actions were taken.

Enterprise EDR solutions include antivirus functionality — they perform signature-based detection in addition to behavioral analysis, so deploying EDR does not require maintaining a separate antivirus product. In practice, EDR replaces antivirus as the primary endpoint protection tool and adds behavioral detection, automated response, forensic telemetry, and SOC integration on top of the signature-based baseline. For businesses running standalone antivirus, the transition to managed EDR replaces and upgrades the existing endpoint protection. For businesses running Microsoft Defender, managed EDR either replaces Defender or layers on top of it depending on the solution deployed and the organizational environment.

EDR agent deployment is typically completed within one to two weeks for most NJ, NY & CT business environments. Agent deployment is remote — agents are pushed to workstations, laptops, and servers through the management console without requiring physical access to each device or disrupting users. Server deployments may require a brief scheduled maintenance window. Once agents are deployed, behavioral detection is active immediately. SOC enrollment and alert pipeline configuration is completed during the same deployment window. Initial tuning of false positive alerts occurs over the first two to four weeks as the EDR solution learns the specific software and administrative patterns in your environment.

No long-term lock-ins. We offer month-to-month and annual agreements. Managed EDR is most effective as a continuously active program — the behavioral tuning improves over time, threat intelligence feeds update continuously, and the SOC relationship with your environment deepens as analysts become familiar with your normal behavioral patterns. Organizations stay with Gradius EDR because every alert is reviewed, confirmed threats are responded to before damage occurs, and the combination of behavioral detection and SOC review delivers protection that standalone antivirus or unmanaged EDR simply doesn't match. We earn the renewal through performance.
