BP Bohdan P. Founder & CEO Information Technology and Services Small-Business (50 or fewer emp.) 8/7/2026 "Reliable 24/7 coverage without extra headcount" 5/5 What do you like best about UnderDefense MAXI? We no longer have to worry about missing a critical issue outside of work hours. Escalations come to us fully explained, including what happened, what was ruled out, and what actually needs our input. We don't get buried in technical noise. Their 2-minute alert-to-triage speed isn't just on paper, as we've personally seen them act on a weekend night Review collected by and hosted on G2.com. What do you dislike about UnderDefense MAXI? The platform needed a few weeks to calibrate to our specific stack and learn our normal traffic patterns, which meant a bit more communication early on Review collected by and hosted on G2.com. What problems is UnderDefense MAXI solving and how is that benefiting you? We don't have a round-the-clock internal security team, but our staff works inside critical client environments with financial data. If something goes wrong at 2 AM, we need to know someone is on it. UnderDefense gives us that protection. On top of that, filling out complex security questionnaires for new enterprise clients is much easier now because we have proof of 24/7 monitoring.

Chief Technology Officer Mid-Market (51-1000 emp.) 8/3/2026 "Solved the risk of developer credential exposure across dozens of client environments" 5/5 What do you like best about UnderDefense MAXI? "When you run 130 engineers across 45+ active client projects, a compromised developer credential isn't a contained problem. It's exposure across every environment that person accessed: fintech platforms, healthcare systems, supply chain infrastructure. Someone is watching that constantly now. When something fires, the Agentic SOC classifies it, pulls the relevant logs, maps to MITRE ATT&CK, and routes a structured verdict with reasoning before it reaches a human. By the time it gets to our team, the investigation is done. We're making a decision, not starting from a raw alert at midnight. Our engineers stopped being the default first responders. That change alone was worth it. " Review collected by and hosted on G2.com. What do you dislike about UnderDefense MAXI? "Nothing that's genuinely bothered us. If anything, we underestimated how much calibration time we'd need upfront. " Review collected by and hosted on G2.com. What problems is UnderDefense MAXI solving and how is that benefiting you? The risk of operating inside client environments at our scale needed a different answer than what we had. 130 engineers touching dozens of production systems is a specific threat model. We needed monitoring that matched it, not generic infrastructure alerts. Review collected by and hosted on G2.com.

VP of Technology Enterprise (\> 1000 emp.) 6/26/2026 "Brought Elastic, SentinelOne, AWS, Azure. Nothing Replaced. The Whole Stack Got Sharper." 5/5 What do you like best about UnderDefense MAXI? We evaluated several MDR providers before choosing UnderDefense. What stood out in the PoC: investigation speed, and the platform layering on top of our existing tools rather than replacing them. SentinelOne, Microsoft Defender, and our 4TB Elastic SIEM deployment stayed in place. The UnderDefense team configured and tuned the entire environment end-to-end. 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, no separate tooling per location. In April 2026, proactive threat hunting caught a phishing campaign we had zero visibility on, traced it to a Microsoft 365 Direct Send misconfiguration, and delivered a full root cause analysis and fix the same day. The team's day-to-day changed after this engagement: less reactive work, more time on infrastructure, and a level of confidence in coverage we didn't have before. Review collected by and hosted on G2.com. What do you dislike about UnderDefense MAXI? Detection tuning to our multi-cloud environment took a few months before coverage was fully dialed in. The team guided us through it, but factor that into your onboarding timeline. Review collected by and hosted on G2.com. What problems is UnderDefense MAXI solving and how is that benefiting you? We went from 840 to 2,500+ endpoints across five countries without growing the security team. The platform works on top of our existing 4TB Elastic SIEM, SentinelOne, and Microsoft Defender deployments with no migration and no vendor lock-in. Pricing was transparent and significantly more cost-effective than the alternatives we evaluated at comparable coverage depth. Review collected by and hosted on G2.com.

Teacher Mid-Market (51-1000 emp.) 7/9/2026 "AI-Powered Correlation with Human-Validated Verdicts" 5/5 What do you like best about UnderDefense MAXI? I like that the platform combines autonomous data gathering with human oversight. The AI agents handle all the correlation and evidence packaging across our SIEM, EDR, and identity systems, but a dedicated human analyst reviews the verdict and validates the recommendation before contacting us. This model avoids the issues 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. Review collected by and hosted on G2.com. What do you dislike about UnderDefense MAXI? 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. Review collected by and hosted on G2.com. What problems is UnderDefense MAXI solving and how is that benefiting you? 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. Review collected by and hosted on G2.com.

Our day-to-day work centers on high-volume data engineering and software development, so our security telemetry is tightly wired into our Splunk setup. When we decided to add AI capabilities to our SOC, every vendor we spoke with tried to force a platform shift — either migrating us to their stack or moving 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 week one 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. Review collected by and hosted on G2.com. What do you dislike about UnderDefense MAXI? 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 take ownership of provisioning the compute and storage resources up front before going live. Review collected by and hosted on G2.com. What problems is UnderDefense MAXI solving and how is that benefiting you? 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.

What sets the UnderDefense Agentic SOC apart is its ability to conduct 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 simply forwarding raw alerts, the platform's AI agents actively investigate them. They pull the 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. Review collected by and hosted on G2.com. What do you dislike about UnderDefense MAXI? 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. Review collected by and hosted on G2.com. What problems is UnderDefense MAXI solving and how is that benefiting you? 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.

CTO Mid-Market (51-1000 emp.) 1/18/2025 "High-level service and cybersecurity expertise" 5/5 What do you like best about UnderDefense MAXI? We recently worked with UnderDefense on a penetration testing project, and the experience exceeded our expectations. Their team provided us with clear and detailed insights into security vulnerabilities, along with practical recommendations on how to fix them. This level of transparency made it easy for our team to take action and strengthen our security. Beyond the testing itself, UnderDefense also helped us navigate key compliance requirements, ensuring we met industry standards smoothly and efficiently. What stood out the most was their responsiveness and flexibility—no matter the issue, they tackled it quickly and professionally. It’s clear they take security seriously and genuinely care about their clients.

The biggest win for me was getting actual control over our security alerts. Before the guys from UD stepped in, we were getting bombarded with alerts from all our security tools. Their team cleaned up our configurations and got the noise under control within the first week. Now when we get an alert, we know it's something worth looking into. The platform itself is straightforward - it pulls in data from all our existing security tools, so we didn't have to rip and replace anything. Their SOC team is responsive and knows their stuff. When they escalate something, they include the context we need to understand the issue quickly. We're not wasting time piecing together what happened from different systems anymore. Review collected by and hosted on G2.com. What do you dislike about UnderDefense MAXI? Setting everything up took some back and forth to get our tools properly integrated. Not really a complaint since it's expected, but worth mentioning for others considering the service. You'll need to dedicate some time upfront to get things configured properly. Review collected by and hosted on G2.com. What problems is UnderDefense MAXI solving and how is that benefiting you? The biggest problem they solved was our 24/7 coverage gap. We needed round-the-clock monitoring for compliance reasons, but building our own SOC wasn't realistic with our budget and the current hiring market. UnderDefense fills that gap without us having to hire a full team. They've also made our audit process much less painful. The reports from their platform give us clear evidence of our security controls and incident response capabilities. When auditors or clients ask questions about our security posture, we can pull up exactly what they need to see. Worth every penny for us. The service delivers what they promised without the typical vendor overselling and underdelivering we've experienced with others in this space. Review collected by and hosted on G2.com.
