FirmGuardian is a managed detection and response (MDR) service that combines endpoint agents with human-led security operations to detect, investigate, and respond to cyber threats. **Visibility & Telemetry:** Behavioral and signature-based endpoint agents are deployed to collect telemetry from endpoint machines. The data collected exceeds what conventional antivirus programs provide. **Detection:** Threat detection uses next-generation EDR software, combining traditional virus signature matching with behavioral analysis mapped to the MITRE ATT&CK framework. Public and private threat intelligence feeds are also incorporated into the detection process. **Investigation:** A dedicated Security Operations team performs manual alert triage using proprietary alert ingestion tooling to reduce false positives. Threat Hunting is conducted to identify false negatives and anomalies in computing behavior that automated systems may miss. **Incident Response:** Automated response actions are initiated by resident endpoint agents to quarantine and delete suspicious files, reducing mean time to remediate (MTTR). Human analysts supplement automated responses for more complex incidents, and forensic data is collected during response activities to inform ongoing defenses.
