The company, at a glance
Quick answer
Xcitium is a zero-trust endpoint-security vendor built on a genuinely different idea: instead of trying to detect whether unknown files are malicious (and inevitably missing some), it contains every unknown by default \u2014 running it in a lightweight virtual container where it can't cause real harm, no matter what it turns out to be. This patented ZeroDwell Containment technology is the prevention-first foundation of everything Xcitium does, captured in its bold promise: 'no ransomware', because ransomware (which needs to run and encrypt real files) is contained before it can act. Xcitium is the rebranded Comodo Security Solutions (rebranded 2022, HQ in Bloomfield NJ, founder-led by Melih Abdulhayoglu) \u2014 a company with deep endpoint-security heritage and a strong MSP and SMB channel. Its thesis: detection-based security always leaves a gap (novel threats run before they're caught), so the answer is to contain the unknown preemptively (zero dwell time), THEN add detection and response on top. So Xcitium's platform is prevention-first: ZeroDwell Containment beneath, with EDR (endpoint detection & response), XDR (extended cross-surface detection), and MDR (24x7 managed detection & response) built on it. It's notably value-oriented and MSP-friendly \u2014 bringing strong, containment-based endpoint security (and affordable MDR) within reach of SMBs, mid-market and MSPs, not just large enterprises \u2014 and it maintains OpenEDR, a free, open-source EDR, reflecting its accessible-security philosophy. Xcitium is a differentiated challenger to the detection-first leaders (CrowdStrike, SentinelOne), chosen for its containment approach and value. TechBag scopes, licenses and supports the Xcitium platform in INR/GST for Indian organisations.
Twelve intel pages. One integrated platform.
The complete Xcitium platform — every linked card is a full intel page, from the patented containment core to the free open-source EDR.
ZeroDwell Containment
Contain the unknown, don't just detect.
The patented, preemptive technology at Xcitium's heart \u2014 automatically run every unknown, untrusted file in a lightweight virtual container by default, so it can't harm the real system regardless of whether it's ever detected as malicious. Ransomware and zero-days are neutralised before they can act ('no ransomware'), with zero dwell time and no detection gap \u2014 and users aren't blocked. The prevention-first foundation of the whole platform.
Xcitium EDR
See and handle threats, on containment.
Endpoint detection and response \u2014 continuous telemetry and visibility, behavioural threat detection, investigation, threat hunting, and response (isolate a host, kill a process, remediate) \u2014 built distinctively on the ZeroDwell containment foundation, so it's contain-then-detect-and-respond, not detection-only. At accessible value, MSP-friendly. The visibility and response you need, on a prevention-first base.
Xcitium XDR
Catch attacks that span surfaces.
Extended detection and response \u2014 correlate signals across endpoint, network, email, cloud and web into one unified view to detect and respond to sophisticated, multi-stage attacks that single-surface tools miss. On the containment foundation (prevention-first), at value that brings XDR within reach of MSPs, SMBs and mid-market \u2014 not just enterprises. Cross-surface breadth plus preemptive prevention.
Xcitium MDR
Experts run your security, around the clock.
24x7 managed detection and response \u2014 Xcitium's SOC monitors, detects, investigates, hunts and responds to threats for you, around the clock \u2014 so you get expert security operations without building or staffing a SOC (solving the skills shortage, acute in India). On the containment foundation, and positioned as affordable MDR that brings 24x7 managed security within reach of SMBs, mid-market and MSPs' clients.
OpenEDR
Genuine EDR, free for everyone.
Xcitium's free, open-source EDR \u2014 genuine endpoint telemetry, real-time monitoring and analytic threat detection at no cost, with open, inspectable code. For budget-constrained organisations, MSPs, researchers, learners and the community \u2014 real EDR visibility for everyone. Self-run (no containment or managed response \u2014 those are commercial), and an on-ramp to Xcitium's full platform. Reflects the accessible-security philosophy.
Cloud Security (CNAPP / CWPP / CSPM)
Platform & enginePlatform expansion into cloud-workload and cloud-security-posture management \u2014 extending Xcitium's protection to cloud and container workloads, alongside the endpoint focus.
SASE / ZTNA / Network
Platform & engineNetwork-security expansion (SASE, ZTNA, secure web) \u2014 broadening the zero-trust approach from the endpoint to network access, as Xcitium extends its platform.
Why “contain the unknown” is the whole story
Detection-based security always leaves a gap — novel threats run before they’re caught. Xcitium bet oncontaining the unknown preemptively, then detecting & responding— patented ZeroDwell Containment that neutralises ransomware and zero-days before they can act, beneath EDR, XDR, MDR and free OpenEDR doubled down on it.
The Foundation (ZeroDwell)
Patented containment \u2014 run every unknown in a virtual container by default, so ransomware and zero-days can't harm the system regardless of detection. Zero dwell time. The prevention-first base of everything.
Detection & Response (EDR)
Endpoint detection and response on the containment foundation \u2014 telemetry, behavioural detection, investigation, hunting and response \u2014 so you see and handle threats, on a prevention-first base, at value.
Extended (XDR)
Extend detection and response across endpoint, network, email, cloud and web, correlating signals to catch multi-stage attacks single-surface tools miss \u2014 cross-surface breadth on the containment foundation.
Managed (MDR)
24x7 managed detection and response \u2014 Xcitium's SOC runs security operations for you \u2014 so you get expert round-the-clock security without a SOC, affordably, solving the skills shortage. On containment.
Free & Open (OpenEDR)
Free, open-source EDR \u2014 genuine telemetry and detection at no cost, inspectable and community-driven \u2014 the accessible entry point, reflecting the belief that EDR should be available to all.
Start with containment (ZeroDwell) and EDR, extend to XDR, add managed MDR if you can’t staff a SOC — or start free with OpenEDR.

Five pitfalls that cost buyers quarters
Relying only on detection
Detection-based security (even the best) always leaves a gap \u2014 novel threats run before they're detected, and some are missed entirely. Xcitium's containment closes this: contain the unknown preemptively (zero dwell time), so ransomware and zero-days can't act regardless of detection. Don't rely solely on catching threats in time.
Assuming default-deny means blocking legitimate work
Strict default-deny (allow-listing) blocks unknown files \u2014 secure but high-friction, disrupting legitimate work. Xcitium's containment gives default-deny security WITHOUT blocking: unknowns run (contained), so legitimate work isn't disrupted. You can have security and usability \u2014 containment delivers both.
Thinking strong endpoint security is only for enterprises
The premium leaders are enterprise-priced, leaving SMBs and MSPs stuck with basic AV. Xcitium is value-oriented and MSP-friendly \u2014 strong containment-based security and affordable MDR within reach of smaller organisations. And OpenEDR is free. Effective security shouldn't require an enterprise budget.
Trying to build your own 24x7 SOC
Building and staffing a 24x7 SOC is expensive and, given the security skills shortage (acute in India), extremely hard \u2014 impractical for most. Xcitium MDR provides expert 24x7 security operations as an affordable service. Don't try to build what you can buy as a managed service.
Expecting a challenger to match the leaders' detection ecosystem
Xcitium is a differentiated challenger \u2014 its edges are the containment approach and value, NOT a market-leading detection/threat-intelligence ecosystem or brand (where CrowdStrike and SentinelOne lead). Choose Xcitium for containment-based prevention and value; the leaders for the deepest detection. Compare honestly, per your priorities.
