"An intelligent layer over our security stack that genuinely reduces operational burden"
What makes the UnderDefense Agentic SOC stand out is its ability to perform end-to-end triage autonomously. In our environment, which handles high volumes of integrations, data transfers, and SaaS configurations, alert fatigue can easily become a major resource drain. Instead of just forwarding raw alerts, the platform's AI agents actively investigate them. They pull relevant context from our logs, correlate user activity across our infrastructure, and determine whether a flag is a false positive or an actual threat. The depth of the automated investigations is impressive, allowing our internal team to step back from the daily grind of log analysis and focus on broader architecture and strategy. Transitioning to an autonomous system required a shift in our team's operational habits. Early on, our engineers instinctively spent time manually verifying the AI’s conclusions until we grew comfortable trusting its automated investigation paths. It simply takes a few weeks to adapt to this new way of working, but the system becomes highly efficient once that initial adjustment period is complete. We needed to maintain continuous, enterprise-grade visibility across our infrastructure without ballooning our engineering headcount or forcing a disruptive migration to a proprietary data lake. UnderDefense solved this by integrating directly with the tools we already have in place. The main benefit is the immediate reduction in noise. Because the AI filters out the background anomalies and presents fully investigated incidents with clear timelines, our response times are faster, and our team isn't burning out on repetitive analysis.

"Autonomous AI SOC on top of our Splunk with no migration needed"
Our work is centered on high-volume data engineering and software development, so our security telemetry is deeply integrated into our Splunk setup. When we looked to add AI capabilities to our SOC, every vendor we talked to tried to push a platform shift—either moving us to their stack or transferring our logs out of our environment. UnderDefense was the only team that took a pragmatically open approach. They connected directly to our Splunk setup in the first week with zero log re-formatting and zero data migration. Keeping full control of our data lake while gaining autonomous threat triage gave us immediate value without the operational friction. As their Agentic SOC runs natively inside our own cloud setup, it's not an off-the-shelf SaaS tool you can activate in five minutes. Our infrastructure team had to own the provisioning of compute and storage resources up front before going live. We needed to drastically speed up alert triage without forcing our engineers onto a new platform or abandoning our existing infrastructure investments. UnderDefense gave us AI-driven incident handling directly on top of our live environment, saving us months of migration work and letting us retain our existing security setup.

"AI-Driven Correlation with Human-Verified Verdicts"
I appreciate that the platform combines autonomous data collection with human oversight. The AI agents handle all the correlation and evidence gathering across our SIEM, EDR, and identity systems, but a dedicated human analyst reviews the verdict and validates the recommendation before contacting us. This approach avoids the pitfalls of AI-only tools that automate verdicts without human validation, as well as copilot tools that still require our team to do the heavy lifting and manual querying. The AI does the grunt work, but judgment stays with a human. Adjusting to a workflow where AI does the initial data gathering took a little time for our team to trust, but support team helped us navigate the transition smoothly. I was skeptical of using AI security systems that make automated decisions without a human review layer. This platform solved that concern by changing how we handle incident investigation. Instead of spending hours doing manual data gathering during an incident, we now receive a complete, AI-prepared brief that has already been verified by a real analyst. This allows us to make confident containment decisions quickly, which is exactly the kind of AI-assisted security we need.

"Enhanced Elastic, SentinelOne, AWS, Azure. Nothing Replaced. The Entire Stack Got Smarter."
We compared several MDR providers before settling on UnderDefense. What impressed us in the PoC was the speed of investigation and the fact that the platform sits on top of our current tools instead of swapping them out. SentinelOne, Microsoft Defender, and our 4TB Elastic SIEM deployment stayed as they were. The UnderDefense team set up and fine-tuned the whole environment from start to finish. Our operation spans five countries, and the coverage model works consistently across all of them—same escalation paths, segmented visibility by org unit and region, and no different tooling per location. In April 2026, proactive threat hunting uncovered a phishing campaign we had no idea about, traced it to a Microsoft 365 Direct Send misconfiguration, and provided a full root cause analysis and fix the same day. After this engagement, our team's daily work changed: less reactive firefighting, more time on infrastructure, and a confidence in coverage we didn't have before. Detection tuning to our multi-cloud environment took a few months before coverage was fully dialed in. The team guided us through it, but expect that in your onboarding timeline. We expanded from 840 to 2,500+ endpoints across five countries without adding security staff. The platform works with our existing 4TB Elastic SIEM, SentinelOne, and Microsoft Defender deployments with no migration and no vendor lock-in. Pricing was clear and much more cost-effective than other options we considered at similar coverage levels.

"Took care of the developer credential theft risk across many client setups"
With 130 engineers working on over 45 active client projects, a stolen developer credential isn't a minor issue; it's exposure across all environments that person accessed, including fintech, healthcare, and supply chain systems. Someone is now monitoring that constantly. When something triggers, the Agentic SOC classifies it, pulls relevant logs, maps it to MITRE ATT&CK, and sends a structured verdict with reasoning before a human gets involved. By the time it reaches our team, the investigation is complete. We're making a decision rather than starting from a raw alert at midnight. Our engineers are no longer the first responders by default. That change alone was worth it. Nothing has really bothered us, except maybe underestimating how much calibration time we'd need upfront. Operating inside client environments at our scale required a different solution than what we had. 130 engineers touching dozens of production systems is a specific threat model, and we needed monitoring that matched it rather than generic infrastructure alerts.

"Dependable round-the-clock coverage without hiring more staff"
We don't have to stress about missing critical issues after hours anymore. Escalations reach us fully explained, covering what happened, what was ruled out, and what we actually need to do. We aren't overwhelmed with technical details. Their claimed 2-minute alert-to-triage response isn't just marketing; we've seen them act on a weekend night. The platform needed a few weeks to adjust to our particular stack and learn our usual traffic patterns, which meant extra communication at the start. We don't have a 24/7 internal security team, but our employees work in critical client environments with financial data. If something goes wrong at 2 AM, we need to know someone is handling it. UnderDefense gives us that assurance. Additionally, filling out complex security questionnaires for new enterprise clients is now easier because we have proof of round-the-clock monitoring.

"Live tracking of investigation steps and detailed incident records"
The platform gives us full insight into the work behind every alert. When we look into an investigation, we see the exact actions taken: which data sources were examined, what evidence was gathered, and the specific reasons for the conclusion. This is a big change from traditional providers that just send a brief alert, or other AI tools that give a verdict without explaining how it was reached. Having the complete trail, including which analyst verified the findings, makes it much simpler to understand what happened. There were no significant issues, just a little time needed to get used to navigating such comprehensive logs, but their team was very supportive during onboarding and got us up to speed quickly. We moved from a provider whose escalations were just a short paragraph and a phone number, leaving us to do the investigation ourselves. This platform solved that by offering a real-time view of the whole investigation. The main advantage is the quality of the technical logs. If there's a possible incident, our team doesn't have to redo or reformat anything; we can use the raw investigation logs as they are.

"Lifted the investigation burden while keeping us in control"
Our engineers spend their days in databases handling migrations, running bulk scripts, and having direct access to production across many systems. Any security tool would view that as constant noise, and updating exclusion rules that kept breaking with each infrastructure change consumed time we couldn't spare. What made the difference is the AI learning our operational context instead of just looking for patterns. A developer running a heavy script during a scheduled maintenance window gets automatically accepted, and analysts only see alerts that require a decision. It integrated with our current SIEM and identity provider without any reconfiguration, and starting in advisory mode before granting more autonomy made getting internal approval easy. The initial two months were noisy as it adjusted to our environment, which was expected, but we set expectations internally beforehand. The large amount of alerts from a big engineering team with privileged DB access was destroying analyst productivity. Now routine triage happens automatically, and the team only handles escalations that truly need a human. We saw a noticeable improvement in workload within the first three months.

"Solid security oversight for an agency juggling many client setups"
Our agency runs marketing campaigns, manages ad accounts, and keeps websites running for clients in various sectors. A security issue in any one of those environments leads to client complaints, not just technical headaches. We required protection that matched that level of exposure without having to create an in-house security team. The UnderDefense analyst assigned to us understands our infrastructure and only contacts us when something genuinely needs our attention. Our staff can concentrate on client work, and if a security event occurs, we receive a thorough explanation rather than having to piece it together ourselves. Nothing major, although we did have a few technical meetings during setup to tailor the detection rules to our environment, which went smoothly overall. We needed security coverage we couldn't build ourselves. As a marketing agency, we handle client data, ad accounts, and website infrastructure, but security isn't our primary focus. UnderDefense takes care of the monitoring so our team doesn't have to switch gears into security tasks, allowing us to remain dedicated to client delivery.
