"Automated security monitoring that investigates complex operational signals before escalating"
5/5
What do you like best about UnderDefense MAXI?

Authentication patterns across hundreds of API integrations are monitored continuously. When something deviates, it gets investigated automatically and reaches us with the work already done. We review a finding with context, not a raw log with no one to trace it.

We manage access to client advertising accounts across multiple platforms at significant volume. One compromised token can cause real damage within hours. Monitoring that manually across a distributed team wasn't viable. UnderDefense Agentic AI SOC covers that layer continuously. By the time something escalates to us, less than 2 minutes have passed since the signal. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

Nothing that has materially affected the outcome. Documentation on integration specifics could be more detailed upfront to reduce back-and-forth during setup. Review collected by and hosted on G2.com.

"Autonomous monitoring that actually understands dev workflows and cuts out noise"
5/5
What do you like best about UnderDefense MAXI?

The main win for us is how it handles monitoring across a large infrastructure without getting in the way of our daily engineering. It connects right into our cloud setup, code repos, and identity providers, filtering out all the background noise from routine deployments and temp credentials.

Instead of blowing up our Slack with false alarms, it quietly triages everything and only pings us when something actually needs a human look. When it does, we get a clear picture of what happened instead of having to dig through raw logs. It took a ton of pressure off our team and gave us solid 24/7 coverage without needing to hire a separate SecOps team. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

No major complaints on our end. The collaboration went well. Review collected by and hosted on G2.com.

"UnderDefense Agentic AI SOC Delivers Trusted 24/7 Coverage With Fast, Validated Alerts"
5/5
What do you like best about UnderDefense MAXI?

Shipping software is what we do. Security operations is a full-time job for people who specialize in it. We delegated it entirely to UnderDefense Agentic AI SOC. Every alert across our infrastructure gets picked up within 2 minutes, investigated by AI agents that correlate events across our environments, and either closed or escalated with full reasoning attached. By the time anything reaches us, the investigation is done. We went from no visibility outside business hours to continuous 24/7 coverage. The findings that reach us are validated. The team stays on the product. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

No real complaints. The service has done exactly what we needed it to do. Review collected by and hosted on G2.com.

"Scaling 24/7 security across multi-timezone projects."
5/5
What do you like best about UnderDefense MAXI?

Our internal IT and ops teams managed day-to-day operations, but maintaining 24/7 monitoring across our active infrastructure and 100+ ongoing projects was impossible. UnderDefense closed those after-hours gaps completely. The biggest win is automated noise reduction: false positives are cut by roughly 80–90% before hitting our queue, so our team only handles high-priority alerts that actually require action. Plus, having full environmental context on every incident saves us hours of manual investigation. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

With this many active projects across different client setups, getting full coverage mapped took a bit longer than expected. Review collected by and hosted on G2.com.

"Background monitoring that investigates and contextualizes alerts before we even see them"
5/5
What do you like best about UnderDefense MAXI?

Managing high-volume infrastructure meant our team was drowning in raw logs and false positives. UnderDefense took that off our plate by filtering out the background noise and isolating real risks.

The platform connects the dots across systems and gives us clean context instead of raw alerts. It caught anomalies we would have spent hours hunting for manually, saving the team real time every week while keeping our monitoring solid. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

No complaints at all, everything was smooth Review collected by and hosted on G2.com.

"Reliable coverage for an agency that handles dozens of client environments"
5/5
What do you like best about UnderDefense MAXI?

We run campaigns, manage ad accounts, and maintain website infrastructure for clients across multiple industries. Security incidents in any of those environments create client escalations, not just technical problems.

We needed coverage that matched that exposure, without building an internal security function. The UnderDefense analyst assigned to our account knows our environments and reaches out when something actually requires our attention.

Our people stay focused on client work, and when a security issue comes up, we're getting a clear picture of what happened rather than trying to figure it out ourselves. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

Nothing significant. Naturally, the onboarding required a few technical syncs to fine-tune detections to our stack, but the process was smooth overall. Review collected by and hosted on G2.com.

"Took the investigative load off without taking control away"
5/5
What do you like best about UnderDefense MAXI?

Our engineers are in databases all day: migrations, bulk scripts, direct production access across multiple environments. Any security tool treats that as constant noise, and maintaining exclusion rules that broke with every infrastructure change was eating time we didn't have.

What shifted things is that the AI learns operational context instead of matching patterns. A developer running a heavy script during a documented change window gets handled automatically. Analysts only see what actually needs a decision. It connected into our existing SIEM and identity provider without rebuilding anything, and starting in advisory mode before gradually extending autonomy made internal sign-off straightforward. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

First two months were noisy while it calibrated to our environment. Expected, but set internal expectations beforehand. Review collected by and hosted on G2.com.

"Real-time visibility into investigation steps and clear incident logs."
5/5
What do you like best about UnderDefense MAXI?

The platform provides complete transparency into the actual work behind every alert. When reviewing an investigation, we can see the exact sequence of actions: which data sources were checked, what evidence was collected, and the specific reasoning behind the conclusion. his approach is a major shift from traditional providers who just send a short alert, or other AI tools that deliver a verdict without explaining how they reached it. Having the full trace, including which analyst validated the findings, makes it much easier to understand what actually happened. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

No major issues. It just took a bit of time to adapt to navigating such detailed logs, but their team was really helpful during the onboarding and got us up to speed quickly. Review collected by and hosted on G2.com.

"Coverage that actually scales with how much traffic our agents handle"
5/5
What do you like best about UnderDefense MAXI?

What I like best is how UnderDefense handles our conversation traffic monitoring. They filter and connect separated signals into clear, actionable alerts, saving us from digging through raw logs. It gives us enterprise security without the cost of building our own security team, and their response times are super fast when it counts. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

Nothing jumps out as a negative for us. Review collected by and hosted on G2.com.

"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.
