The challenges

The problems most security teams are stuck with

If any of these sound familiar, you don't have a tools problem. You have a response problem, and that is exactly what MDR is built to fix.

Alert overload with no one to action it

A deluge from every tool, no context, and a ticket that lands in your queue Monday morning while the real signal stays buried.

You can't staff a 24/7 SOC

Hiring and retaining analysts around the clock isn't realistic on your budget, and nights and weekends are when attackers move.

A compliance deadline with no evidence

SOC 2 or ISO 27001 is due and you have nothing to hand an auditor: no monitoring, no logs, no reporting trail.

"24/7" that only notifies, never acts

A bot leaves you a ticket instead of containing the threat, so dwell time keeps running while you sleep.

Tool sprawl with no single picture

You already own the EDR, the SIEM, the cloud logs. No one is correlating them into one clear, prioritized view.

Rip-and-replace vendor lock-in

Providers that force you onto their agents and their SIEM, writing off the stack you already invested in and making it painful to ever leave.

What our customers say

Matthew Sciberras

"We fully automated T1-T2 manual triage with UnderDefense. AI SOC filters the noise so my team can focus on complex hunt missions and strategic security. We scaled our capacity 10x overnight, not by hiring, but by making our analysts investigators again."

Self-serve / free start
Free MAXI tier
Start free on the MAXI platform, no sales call required. Most rivals require a demo and a signed contract before you can evaluate anything hands-on.
Works with your tools
Falcon-centric
EDR-centric
250+ integrations
Vendor-agnostic across 250+ integrations, with no rip and replace. CrowdStrike leans on its Falcon ecosystem and Huntress is endpoint/EDR-centric, so coverage outside the core can be thinner.
Defined response SLA
2-min triage, 15-min contain
A defined ~2-minute alert-to-triage and containment inside 15 minutes. Most rivals publish no comparable containment SLA, so the clock you are sold can mean very different things.
Multi-environment coverage
Falcon-centric
EDR-centric
Cloud, network, endpoint, identity
One team across your cloud, network, endpoint, identity, SaaS, and Kubernetes, with no blind spots between environments. Many rivals concentrate on a single layer or their own agent and leave the gaps between environments to you.
Agentic AI SOC team
Charlotte AI
MAXI AI SOC
Human analysts paired with the MAXI agentic AI platform, which auto-triages T1 to T2 alerts and maps your VIPs and high-value assets. Your experts spend their time on real investigations instead of clearing a queue, while most providers still run fully manual triage.
Compliance evidence included
12 frameworks
SOC 2, ISO 27001, HIPAA, GDPR, PCI DSS, NIST CSF 2.0, EU-US DPF, DORA, CIS v8, NIS 2, CCPA, and NBU №143 evidence kits plus a 30-day impact report, included. Most rivals leave compliance evidence to a separate platform or service.
