Built on a SIEM core that correlates events, threat intelligence, and malware patterns in real time — before data is indexed — it brings together log management, XDR, SOAR, threat intelligence, vulnerability scanning, and compliance reporting, so teams can monitor, investigate, and respond from a single console instead of stitching together separate tools. UTMStack is EDR-agnostic. It ingests telemetry from the endpoint, network, cloud, and identity tools you already use — including CrowdStrike, SentinelOne, Sophos, Palo Alto, Fortinet, AWS, Azure, and Microsoft 365 — and correlates everything centrally, with no rip-and-replace. The SOC-AI module supports both built-in and custom machine-learning models for AI-assisted analysis, and pre-built reporting helps teams meet frameworks such as CMMC, NIS2, SOC 2, HIPAA, ISO 27001, and PCI-DSS. Licensed under AGPL-3.0 and member of the Linux Foundation UTMStack is free to self-host, with paid plans for enterprise support, advanced AI, and compliance — plus multi-tenant and OEM licensing for MSPs and MSSPs. ## UTMStack Reviews ### 1. A solid free SIEM that is worth a look **Rating:** 4.5/5.0 stars **Reviewed by:** Corey S. | Network Support Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** August 04, 2026 **What do you like best about UTMStack?** The setup was pretty easy, and the free version is pretty complete. I think it's a great option for businesses that are cost sensitive. The UI is intuitive and the features are in places that make sense w/o having to dig around. The software integrates with quite a few technologies, including Windows & Linux Hosts. Performance on the VM I created for it seems fine, and I have not had many issues w/ slowdowns or crashes. Community support for the software has been pretty decent, and we have considered purchasing support. There is no AI integrated that i am aware of. **What do you dislike about UTMStack?** On occasion, it goes a little crazy with some alerts. And there are some bugs, but they are not typically breaking. **What problems is UTMStack solving and how is that benefiting you?** It provides a centralized source to check logs and alerts at minimal cost & setup. ### 2. UTMStack: All-in-one security with efficient correlation and no-code compliance **Rating:** 5.0/5.0 stars **Reviewed by:** Andres A. | UX/UI Designer, Small-Business (50 or fewer emp.) **Reviewed Date:** June 15, 2026 **What do you like best about UTMStack?** What I like most about UTMStack is its genuine “All-in-One” approach to security management. Rather than dealing with the high costs and integration headaches that come with maintaining separate tools for SIEM, XDR, and SOAR, UTMStack brings everything together in a single, cohesive ecosystem. From an architectural standpoint, it feels highly efficient. Because it uses its own proprietary correlation engine—instead of relying on heavier, resource-intensive ELK or Kibana setups—it can filter and correlate log data before ingestion. That approach significantly reduces false positives, helps eliminate alert fatigue, and keeps infrastructure costs under control. On top of that, its compliance management capabilities are extremely valuable. The built-in “no-code” compliance builders for frameworks like SOC 2, HIPAA, and ISO 27001 transform what used to be a weeks-long, manual auditing effort into a more streamlined and automated process. When you add in the seamless cloud integrations (AWS, Azure) and the recent AI-driven SOC analysis, it delivers enterprise-grade visibility and automation that still feels accessible for smaller cybersecurity teams. **What do you dislike about UTMStack?** What I dislike most is the initial learning curve and setup complexity for specific hybrid environments. While the web interface is clean and modern, deploying sensors and agents across highly customized on-premises infrastructure or legacy Linux distributions often requires a deep understanding of the command line, which can be challenging for junior IT administrators. Additionally, the documentation could be more comprehensive. While the community and support are helpful, finding detailed guides for creating highly advanced, custom correlation rules or complex parsing scripts from scratch takes more time than it should. Finally, although their cloud and major SaaS integrations (like Office 365 and AWS) work flawlessly, expanding the native integration library to include more niche, third-party security tools would prevent the need for manual API configurations. **What problems is UTMStack solving and how is that benefiting you?** UTMStack solves the critical problem of security tool sprawl and skyrocketing licensing costs. Before using it, maintaining full visibility meant paying for and managing multiple disparate solutions (a standalone SIEM, a vulnerability scanner, an IDS, and compliance tracking software). UTMStack consolidates all of these capabilities into a single platform, eliminating the complexity of managing multiple vendors and disparate data formats. The most tangible benefit is the radical automation of compliance auditing and incident response. Thanks to its built-in compliance frameworks (like SOC 2 and ISO 27001), gathering evidence for auditors is no longer a manual, weeks-long headache; the platform generates the required reports automatically. Furthermore, its built-in SOAR capabilities allow us to automate threat containment (like isolating an endpoint or blocking an IP) the moment a real threat is detected. This has drastically reduced our Mean Time to Detection (MTTD) and Mean Time to Remediation (MTTR), allowing a lean security team to maintain a robust, proactive defense posture without burning out. ### 3. Powerful Open-Source SIEM That Cuts Noise and Delivers Solid Performance **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** June 15, 2026 **What do you like best about UTMStack?** I've known UTMStack since the early days, when their whole mission was making cybersecurity affordable for small companies — which is exactly what we were. As a cybersecurity company ourselves, compliance isn't optional, and UTMStack has had us covered there from the start. Over the years it's grown into so much more than threat detection. When they integrated the SOC AI they were pioneers in that space, and it genuinely changed how we work — it cuts through the noise and helps us focus on what actually matters. Performance has also been very solid. It has been working with fewer resources than we expected for the amount of data we send, which has been a pleasant surprise. The real-time pre-ingestion correlation is a game changer compared to traditional SIEMs, and the all-in-one open-source approach — SIEM, XDR, SOAR, and vulnerability scanning under one roof — means no more stitching together multiple tools. For a lean security team, that's a big deal both operationally and cost-wise. Yes, the UI could use some polish, but honestly that's the least of my concerns — I'm not here for aesthetics, I'm here for what the core does, and the core delivers. To be honest, I haven’t needed support very often, but when I did open a ticket, I received professional treatment and fast resolution. It supports all major vendors out of the box, but what I really appreciate is that you can build your own integrations on top of it using their flexible ingestion and correlation rules. It's not hard if you read the docs. Overall, it's been a great journey with one of the most capable open-source SIEMs on the market. **What do you dislike about UTMStack?** Setting up your own instance can be hard for users without technical experience, especially during the installation and initial configuration **What problems is UTMStack solving and how is that benefiting you?** UTMStack helps us centralize all the security events from our infrastructure into one place, which is critical because we’re a cybersecurity company and face attacks every day. The SOC AI has also helped uncover vulnerabilities in our security posture that we were able to fix, and it reduces the need for a full team to manually review alerts and create incidents, making us more efficient and cost-effective as an organization. ### 4. UTMStack: complete security, robust integrations, and support that facilitates onboarding **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Small-Business (50 or fewer emp.) **Reviewed Date:** June 14, 2026 **What do you like best about UTMStack?** UTMStack seems to me a very comprehensive solution for security: it has a clear interface, good integrations, stable performance, and a price that provides good return. Additionally, the support and onboarding greatly facilitate its use, while its AI features help improve detection and analysis. **What do you dislike about UTMStack?** UTMStack is a useful tool, but I think it could still improve in some aspects. The interface can feel somewhat complex at first, certain integrations require more configuration than expected, and some AI functions could be more intuitive. Even so, the support helps a lot during the process. **What problems is UTMStack solving and how is that benefiting you?** UTMStack helps to centralize logs, detect alerts, and manage incidents from a single platform. This is beneficial because it improves the visibility of the environment, reduces analysis time, and allows for a quicker and more organized response to potential threats. ### 5.
