OpenEDR is Xcitium's free, open-source Endpoint Detection and Response platform — an open-source initiative that gives organisations, MSPs and the security community full EDR telemetry and detection capability at no cost, with the source code openly available — so anyone can gain endpoint visibility and threat detection, inspect and trust the code, and build on it. It exists because Xcitium (formerly Comodo) believes endpoint detection and response should be accessible to everyone, not locked behind expensive licences — so it open-sourced a genuine EDR: OpenEDR provides real-time endpoint monitoring and rich telemetry (process, file, registry, network and behavioural events), analytic detection of malicious techniques (mapped to attack frameworks), and the visibility security teams and analysts need to detect and investigate threats — all free and open-source. It's valuable in several ways: for organisations wanting EDR visibility without cost (SMBs, budget-constrained teams, and anyone starting out); for MSPs and security professionals who want to deploy, learn, or build on an open EDR; for the security community and researchers who benefit from open, inspectable EDR technology; and as an on-ramp to Xcitium's broader commercial platform (containment, EDR, XDR, MDR) for those who later want managed response, containment prevention, or enterprise features. Being open-source also means transparency (you can inspect the code) and community (contributions and trust). OpenEDR reflects Xcitium's accessible, community-friendly philosophy — the same that underlies its value-oriented commercial offerings. So you get genuine, free, open-source EDR telemetry and detection — real endpoint visibility at no cost. TechBag helps organisations use OpenEDR and, if needed, move to Xcitium's commercial platform, with INR/GST support.

OpenEDR is genuine, free, self-run EDR visibility and detection — without containment prevention or managed response (those are commercial). It's a real free tool AND an on-ramp. TechBag guides the path honestly.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Free & Open
A genuine EDR, free and open-source — the source code openly available — so anyone can gain endpoint visibility and detection without a licence cost, and inspect and trust the code.
Telemetry
Real-time endpoint monitoring and rich telemetry — process, file, registry, network and behavioural events — giving the visibility into endpoint activity that detection and investigation require.
Detection
Analytic detection of malicious techniques — mapped to known attack frameworks (MITRE ATT&CK-style) — so threats and suspicious activity are surfaced from the telemetry, not just collected.
Inspect & Build
Because it's open-source, you can inspect the code (transparency and trust), the community can contribute, and MSPs, researchers and developers can learn from and build on it — open EDR technology.
On-Ramp
OpenEDR is also an on-ramp to Xcitium's commercial platform (containment, EDR, XDR, MDR) — so if you later want containment prevention, managed response or enterprise features, there's a clear path.
One agent on every machine, one console over all of them — modules attach without a second operational world.
Twelve capabilities. Free, detect, grow.
OpenEDR gives genuine EDR telemetry and detection, free and open-source, self-run — the accessible entry point to the portfolio, and paired with the human firewall.
Free & Open-Source
A genuine EDR at no cost, with source code openly available — so endpoint visibility and detection are accessible to everyone, from budget-constrained SMBs to researchers, not locked behind expensive licences.
Real-Time Endpoint Telemetry
Collect rich, real-time telemetry from endpoints — process, file, registry, network and behavioural events — giving the visibility foundation for detection, investigation and threat hunting.
Continuous Monitoring
Continuously monitor endpoint activity in real time — so you see what's happening on your endpoints, the essential visibility that basic antivirus doesn't provide and that EDR is defined by.
Analytic Threat Detection
Detect malicious techniques analytically from the telemetry — surfacing suspicious and malicious activity — so OpenEDR isn't just collecting events but identifying threats worth attention.
Attack-Technique Mapping
Map detected activity to known attack techniques (MITRE ATT&CK-style) — so alerts have context about what attackers are attempting, aiding understanding and prioritisation, even in the free tool.
Investigation Support
Use the telemetry and detections to investigate incidents — tracing activity and understanding what happened — so you can respond, with the visibility that basic AV can't give you.
Open, Inspectable Code
Because it's open-source, the code is open and inspectable — so you can verify what it does, trust it, and (for developers) learn from and build on it. Transparency that closed tools can't offer.
Community & Learning
A community initiative — so security professionals, MSPs, students and researchers can deploy, learn from and contribute to it, and the community benefits from open EDR technology.
A Starting Point for EDR
A great way to start with EDR — gain endpoint visibility and detection at no cost, learn what EDR offers, and evaluate the approach — before deciding whether to move to a commercial platform.
On-Ramp to Xcitium Platform
An on-ramp to Xcitium's commercial platform — if you later want containment prevention, managed response (MDR), extended XDR, or enterprise features, there's a clear path from OpenEDR to the full platform.
Open, No Lock-In
Being open-source means no vendor lock-in on the free tool — you have the code and control — which builds trust and gives flexibility, whether you stay on OpenEDR or move to commercial by choice.
Accessible-Security Philosophy
OpenEDR reflects Xcitium's belief that EDR should be accessible to everyone — the same accessible, community-friendly philosophy behind its value-oriented commercial offerings. Security democratised.

Here’s what genuinely sets Xcitium OpenEDR apart.
EDR visibility and detection — for free
The core value of OpenEDR is simple and significant: it gives you genuine EDR — endpoint visibility, telemetry and threat detection — for free, which matters because EDR has become essential but its cost has been a barrier for many. Why EDR matters (and why free is valuable): endpoint detection and response — the visibility into endpoint activity, the detection of threats via behaviour and telemetry, the ability to investigate — has become a security baseline (basic antivirus is no longer enough; you need to see and detect what's happening on endpoints, and EDR is increasingly a compliance and cyber-insurance expectation). But commercial EDR costs money, and for budget-constrained organisations — small businesses, non-profits, educational institutions, startups, teams just beginning their security journey — that cost can be a barrier to getting essential endpoint visibility, leaving them stuck with basic AV and no real detection or investigation capability. OpenEDR removes the cost barrier: it provides a real EDR — real-time endpoint monitoring, rich telemetry (process, file, registry, network, behavioural events), and analytic detection of malicious techniques — free and open-source. So an organisation that couldn't or didn't want to pay for commercial EDR can still gain genuine endpoint visibility and threat detection, at no cost. This is genuinely valuable: it means essential EDR capability is accessible to everyone, not just those who can pay — democratising a baseline security capability. For SMBs, budget-constrained teams, and anyone wanting to gain endpoint visibility without cost, OpenEDR provides real EDR for free — a meaningful contribution to accessible security. The honest note: free open-source EDR gives you the telemetry and detection, but you provide the effort to run and act on it (there's no included managed response or containment prevention — those are in the commercial platform); still, for the visibility and detection alone, at no cost, it's a strong offering. TechBag helps organisations deploy and get value from OpenEDR.
Open-source — transparency, trust and community
A significant aspect of OpenEDR is that it's open-source — the code is openly available and inspectable — which brings transparency, trust and community benefits that closed, proprietary EDR can't offer. Transparency and trust: with open-source security software, anyone can inspect the code to verify exactly what it does — how it monitors, what it collects, how it detects — rather than trusting a vendor's black box. For security software especially (which has deep access to your endpoints), this transparency is valuable: you can see and verify the tool's behaviour, building trust that it does what it claims and nothing untoward. This is a meaningful advantage for organisations, researchers and the security-conscious who want to understand and trust their security tools. Community: as an open-source initiative, OpenEDR is a community effort — security professionals, MSPs, students and researchers can use it, learn from it, and contribute to it, and the broader security community benefits from open, shared EDR technology. This community aspect advances accessible security and provides a learning resource (understanding how EDR works by examining a real, open EDR). Building on it: developers and MSPs can build on the open code — integrating, extending, or learning from it — which proprietary tools don't allow. And no lock-in: because you have the open code, there's no vendor lock-in on the free tool — you have control and flexibility. So OpenEDR isn't just free EDR — it's open EDR, with the transparency, trust, community, learning and flexibility that open-source brings. For organisations and individuals who value being able to inspect and trust their security tools, who want to learn from real EDR technology, or who want to build on open code, OpenEDR's open-source nature is a genuine benefit beyond just the zero cost. It reflects a philosophy of open, accessible, trustworthy security. TechBag helps organisations leverage OpenEDR's open, transparent EDR.
A starting point — and an on-ramp to the full platform
OpenEDR serves as both an excellent starting point for EDR and an on-ramp to Xcitium's commercial platform — so it's valuable whether you stay free or grow into more, which is a smart, low-friction way to begin an endpoint-security journey. As a starting point: for organisations new to EDR (or moving up from basic antivirus), OpenEDR is a great way to start — gain real endpoint visibility and detection at no cost, learn what EDR offers and how it works, and evaluate the approach in your environment — without spending or committing. You get genuine EDR capability to begin with, and can assess your needs from a position of actually having and using EDR. As an on-ramp: OpenEDR also connects to Xcitium's broader commercial platform — so if, having started with free EDR visibility and detection, you later want more (the ZeroDwell Containment prevention that neutralises unknowns/ransomware preemptively, managed 24x7 response via MDR because you can't staff a SOC, extended cross-surface detection via XDR, or enterprise features and support), there's a clear, natural path from OpenEDR to the commercial Xcitium platform. So OpenEDR lowers the barrier to starting (free, no commitment) while providing a growth path to fuller capabilities when needed. This is genuinely useful: you can begin your endpoint-security journey with free, real EDR, get value immediately, and grow into containment prevention, managed response and extended detection as your needs and budget evolve — all within one vendor's coherent approach. For organisations starting out, budget-constrained, or wanting to evaluate before buying, this start-free-grow-as-needed model is attractive and low-risk. For MSPs, OpenEDR can be a way to begin with clients before moving them to the fuller commercial platform. TechBag helps organisations start with OpenEDR and grow into Xcitium's commercial platform if and when it's right. TechBag guides the path from free to commercial.
Reflects Xcitium's accessible-security philosophy
OpenEDR embodies Xcitium's broader philosophy that security — including EDR — should be accessible to everyone, not locked behind high costs — the same philosophy that underlies its value-oriented, MSP-friendly commercial offerings — which is worth understanding because it explains Xcitium's distinctive positioning. The philosophy: Xcitium (as Comodo before it) has a long history of accessible security — free and low-cost offerings, a strong focus on the MSP and SMB channel, and a belief that effective security shouldn't be the preserve of only those with large budgets. Open-sourcing a genuine EDR (OpenEDR) is a direct expression of this: making a baseline security capability freely and openly available to all. How it connects to the commercial platform: this accessible-security philosophy runs through Xcitium's commercial offerings too — its value-oriented pricing, MSP orientation, and 'affordable' positioning (affordable MDR, accessible EDR/XDR) reflect the same belief that strong security (including the distinctive containment prevention) should be within reach of SMBs, mid-market and MSPs' clients, not just large enterprises. So OpenEDR isn't a marketing gimmick — it's consistent with, and illustrative of, Xcitium's whole approach: democratising security. Understanding this philosophy helps explain why Xcitium is positioned as it is — a value-oriented, accessible, community-friendly security vendor with a distinctive containment technology, rather than a premium enterprise-first player. For organisations that value this accessible-security ethos — wanting effective, affordable, and (in OpenEDR's case) free and open security — Xcitium's philosophy and offerings resonate. And OpenEDR is the purest expression: real EDR, free and open, for everyone. For the security community, budget-constrained organisations, and the accessible-security movement, OpenEDR is a meaningful contribution. TechBag represents Xcitium's accessible-security approach in India. TechBag supports accessible security with Xcitium.
For MSPs, researchers and the community too
Beyond individual organisations, OpenEDR is valuable for MSPs, security researchers, students and the broader security community — because open, free EDR technology serves needs beyond just a single organisation's endpoint protection. For MSPs: OpenEDR gives MSPs a free, open EDR to deploy, learn from, or use as a starting point with clients — valuable for building endpoint-security services, evaluating the technology, or beginning with clients before moving them to Xcitium's commercial platform (with containment, MDR, etc.). MSPs benefit from the free entry point and the path to commercial. For researchers and security professionals: an open, real EDR is a valuable resource — researchers can study how EDR works, test detection techniques, and advance the field using inspectable technology; security professionals can learn EDR by examining and using a genuine open EDR. This educational and research value is significant — open security technology advances the whole field. For students and learners: OpenEDR provides a free, real EDR to learn on — helping build the security skills the industry badly needs (relevant to the skills shortage), by giving learners hands-on access to actual EDR technology at no cost. For the community: the broader security community benefits from open, shared EDR technology — collaboration, contribution, and the advancement of accessible security. So OpenEDR's value extends beyond protecting one organisation's endpoints: it serves MSPs building services, researchers advancing the field, students building skills, and the community sharing and improving open security technology — a contribution to the security ecosystem, not just a free product. This community and ecosystem value is part of what makes OpenEDR meaningful, and reflects Xcitium's engagement with the broader security world. For MSPs, researchers, learners and the community, OpenEDR is a genuinely useful open resource. TechBag supports MSPs and organisations using OpenEDR in India.
The honest scope
OpenEDR is Xcitium's free, open-source EDR — providing genuine endpoint telemetry, real-time monitoring and analytic threat detection (mapped to attack frameworks) at no cost, with open, inspectable source code — valuable for budget-constrained organisations wanting EDR visibility for free, for MSPs and researchers wanting open EDR technology, for the community, and as an on-ramp to Xcitium's commercial platform. The honest framing: OpenEDR gives you EDR visibility and detection for free, but it's important to be clear about what it is and isn't. It provides the EDR telemetry and detection — but you provide the effort to deploy, run, monitor and act on it (there's no included managed service, no 24x7 SOC, no automated response service in the free tool). It does not include Xcitium's distinctive ZeroDwell Containment prevention (that's in the commercial platform) — so OpenEDR is detection-and-visibility, not the containment-based prevention that differentiates Xcitium's commercial offerings. And it lacks the enterprise features, support, managed response (MDR), and extended detection (XDR) of the commercial platform. So OpenEDR is genuine, valuable, free EDR visibility and detection — real and useful — but it's the free, self-run, detection-focused tier, not the full commercial platform with containment prevention and managed services. It's most valuable when you want free EDR visibility and detection and can run it yourself, when you want to start with EDR before deciding on commercial, when you're an MSP or researcher wanting open EDR, or as an on-ramp. For organisations wanting containment prevention, managed 24x7 response, or enterprise capabilities, the commercial Xcitium platform (this suite's other pages) is the fit. TechBag helps you use OpenEDR and, if and when you need more, move to Xcitium's commercial platform — with local support and INR/GST for the commercial offerings.
