Xcitium Cybersecurity —
Zero Trust Endpoint Security, EDR & MDR

Xcitium (formerly Comodo Security) is a cybersecurity company delivering zero trust endpoint security, EDR, and MDR using a patented ZeroDwell Containment technology. Unlike traditional endpoint security that relies on detecting known-bad files, ZeroDwell Containment isolates unknown files and processes in a lightweight virtual container — preventing them from executing any malicious activity on the host system until they are adjudicated as safe or malicious. This approach eliminates the dwell time that allows ransomware, zero-day malware, and advanced persistent threats to cause damage before detection engines catch them.

ZeroDwell Containment is Xcitium's patented endpoint protection approach — automatically containing any unknown file or process in a virtualized kernel-level container where it can execute but cannot access real system resources, write to critical registry locations, or communicate with other processes. While contained, the file is submitted for analysis via Xcitium's verdict cloud. If the file is confirmed clean, it executes normally; if malicious, it is terminated with no damage to the host. This fundamentally addresses the gap in traditional AV and EDR that leaves systems exposed during the analysis window before a verdict is returned.

Xcitium EDR (Endpoint Detection and Response) provides continuous endpoint telemetry collection, threat hunting, behavioral analysis, and automated response capabilities. Xcitium EDR captures process execution trees, network connections, file writes, and registry changes — enabling security teams to investigate alerts, perform retrospective threat hunting, and reconstruct attack timelines. Automated response actions include process termination, file quarantine, and endpoint isolation. Xcitium EDR is enhanced by ZeroDwell Containment — meaning unknown threats are contained automatically while EDR provides the investigation and response workflow.

Xcitium MDR (Managed Detection and Response) provides 24/7 SOC monitoring, threat hunting, incident investigation, and response on behalf of organizations that lack internal security operations capability. Xcitium MDR analysts work within the Xcitium Open EDR platform to monitor endpoints, investigate alerts, triage incidents, and orchestrate response actions. MDR from Xcitium includes guaranteed response SLAs, designated analyst team access, and regular threat reporting. For mid-market organizations without a fully staffed SOC, MDR provides enterprise-grade detection and response as a managed service.

Xcitium serves SMBs and mid-market enterprises across healthcare, financial services, legal, manufacturing, government, and other industries with endpoint security, compliance, and data protection requirements. With over 85 million endpoints protected globally, Xcitium has proven scale and supports organizations from 50 to 50,000+ endpoints. Healthcare organizations particularly benefit from Xcitium's HIPAA-compatible endpoint controls, while financial services firms benefit from zero trust containment that prevents unauthorized data exfiltration and ransomware deployment.

No. Your agreement is directly with Xcitium Cybersecurity — Fibi is not a party to your contract. Fibi evaluates Xcitium alongside competing endpoint security, EDR, and MDR providers based on your industry, endpoint count, compliance requirements, and internal security team capabilities. Fibi's advisory is funded by a referral commission from Xcitium — there is no additional cost to your organization.
