What is UnderDefense?

UnderDefense is an agentic AI SOC, compliance, and MDR platform built to help security teams automate alert investigation, reduce noise, and respond to real threats faster. The platform uses AI agents to investigate every alert, correlate evidence across systems, enrich context, verify findings, and deliver structured verdicts and recommended actions. MAXI is designed to reduce false positives, accelerate triage, and make existing security investments more productive without forcing teams into a proprietary stack. The platform works with tools such as Splunk, Microsoft Sentinel, Google Chronicle, IBM QRadar, Elastic, CrowdStrike, SentinelOne, Palo Alto, AWS, GCP, Azure, Okta, Slack, Teams, Jira, and more than 100 other integrations. Its AI SOC layer provides multi-system correlation, ChatOps verification, Detection Logic as Code, auditable investigation steps, and fast alert analysis. Its compliance layer supports SOC 2, ISO 27001, HIPAA, and PCI DSS through automated evidence collection, questionnaire automation, posture monitoring, and executive-ready reporting. Its expert incident response and MDR layer adds 24/7 human specialists, containment support, co-managed or fully managed security operations, and rapid response workflows. UnderDefense also provides managed detection and response, managed SIEM and EDR, managed SOC, cloud security services, penetration testing, compliance services, external attack surface monitoring, ransomware protection, and incident response automation. The platform is built around the idea that AI should collect and investigate while human teams make final decisions. It supports on-premises and cloud environments, keeps logs in the customer’s data lake, and emphasizes transparent investigation rather than opaque automation.

    The SOC that let us keep building instead of watching alerts

    Date: Aug 04 2026
    Summary

    Bringing in UnderDefense Agentic AI SOC was one of the better calls we made this year. Our team stopped babysitting alerts and started spending that time on work that actually moves things forward. The investigation quality has been consistently solid, and it made financial sense too - building that same coverage in-house would have cost far more in tooling and headcount. It feels like a partnership rather than a vendor relationship, and that comes through in how fast they respond and how well they adapt to how we work.

    Positive

    The real value for us was coverage across our environment, without adding headcount just to watch dashboards. Alerts land already triaged and enriched, so we're not sifting through raw noise to figure out what's actually urgent. Investigations come with clear timelines and evidence, which made it easy to explain what happened without translating raw logs ourselves. Escalations move fast and the analysts clearly understand our environment, not just a generic playbook. Onboarding went smoother than we expected, and it was pulling its weight within the first few weeks.

    Negative

    Tuning took a few weeks to get detections fully aligned with our setup but it was expected, definitely worth planning for.

    AI SOC that genuinely took the load off our team

    Date: Aug 02 2026
    Summary

    Bringing in UnderDefense AI SOC was one of the better decisions we made this year. Our internal team went from chasing alerts to working on things that actually move security forward, and the quality of investigations we receive is consistently high. It also made real financial sense. Building the same level of coverage in house would have cost us significantly more in headcount and tooling, so the budget impact was clearly positive. The relationship feels like a partnership rather than a vendor contract, and that shows in how quickly they respond and adapt.

    Positive

    The biggest win for us was coverage. We got real 24/7 monitoring without hiring more analysts, and the alerts that reach us are already triaged and enriched, so the team is not drowning in noise anymore. Investigations are thorough and easy to follow, with clear timelines and evidence instead of raw logs. When we escalate something, the response is fast and the analysts actually understand our environment. Onboarding was smoother than expected and the platform was useful within the first weeks.

    Negative

    It took a few weeks of tuning on both sides to get detections fully aligned with our environment, which is normal but worth planning for. We would also like a bit more flexibility in building custom dashboards and reports without asking the team for help
