Managed EDR/XDR: Every Endpoint Protected, Every Threat Hunted

Yes. EDR/XDR is a generational replacement for traditional antivirus, not a complement to it. Running both simultaneously creates conflicts, performance degradation, and redundant overhead. Our deployment process includes removing legacy AV during agent rollout. For organizations with contractual commitments to an existing AV vendor, we can advise on timing and transition planning.

Traditional antivirus compares files against a database of known malware signatures — if the signature isn't in the database, the file passes. EDR takes a fundamentally different approach: instead of identifying what a file is, it monitors what the file does. When a process attempts to inject code into another process, access LSASS memory, modify boot records, or encrypt a large number of files in rapid succession, the behavioral AI detects the action pattern as malicious regardless of whether the specific malware family has been seen before. This behavioral detection is why EDR catches zero-days and novel ransomware variants that signature-based tools miss.

Yes, with graduated automation based on confidence level. High-confidence detections — ransomware execution, credential dumping, known malicious tools — trigger immediate automated containment: the endpoint is isolated from the network while remaining manageable by our SOC. Lower-confidence detections generate alerts for analyst triage, with manual response decisions made based on investigation findings. For retainer clients, automated containment is followed by analyst investigation and a remediation decision within the response SLA window. We configure automation thresholds during onboarding based on your risk tolerance and operational requirements.

Yes. Our managed EDR/XDR service covers Windows workstations, Windows and Linux servers, and macOS endpoints. Server coverage is particularly important because servers are high-value lateral movement targets — attackers who compromise a workstation frequently pivot to domain controllers, file servers, and backup servers to maximize impact. We deploy agents across your full endpoint inventory, including any cloud-hosted virtual machines on Azure, AWS, or GCP.

MDR (Managed Detection and Response) is a service category — managed EDR/XDR is the technology and delivery model that most MDR services are built on. When Vigil Cyber delivers managed EDR/XDR, we are providing what the industry calls MDR: the technology platform plus the 24/7 analyst team that monitors it, hunts threats, and responds to incidents. The distinction matters because some vendors sell EDR licenses and call it MDR without providing the managed analyst component. Our service always includes the human SOC layer — the technology alone is not the service.
