Download PDFThe market races to show how fast AI can respond. Your real question is: what happens when it's wrong? At Critical Start, every threat alert — low, medium, or high severity — is validated by a qualified SOC analyst.
Every one of our AI recommendations carries a full audit trail: what the agent proposed, what the analyst decided, and why.
Gartner estimates 60% of AI incidents by 2026 will stem from governance failure. Our answer isn't a policy document, it's the architecture itself.
Most AI security platforms treat cross-customer data sharing as a network effect. For regulated industries, that's a data governance risk. Our architecture keeps telemetry inside your environment. Agents operate on your signal, within your Rules of Engagement, and never share investigation outputs across customers.
Every AI vendor has a benchmark: response in five minutes, triage in seconds, investigation cut by 68%, measured in vendor-controlled environments, against vendor-selected workloads, with no contractual commitment behind them.
Critical Start offers per-alert SLAs, audit-ready obligations on how every signal is handled. The question isn't whose AI is fastest in a demo. It's who will put it in writing.
From your first signal to a resolved verdict, in one flow. AI accelerates every step. Your analysts and ours validate the moments that matter. The result is a contractual, audit-ready outcome.
Every agent proposes. A qualified human approves. Each one has a tightly scoped charter: what it can do, what it cannot, and what it must hand off.
Examines false positives in production and proposes new entries to the Trusted Behavior Registry — the deterministic rules engine that has filtered ~99% of events for more than a decade.
Accelerates triage by pre-populating investigative workflows, running OSINT enrichment, and suggesting verdicts on alerts for analyst review.
Detects, links, and proposes closure of related alerts during triage so analysts work a single coherent case instead of duplicates.
Suggests existing automations from the catalog to run on true-positive verdicts and proposes new workflows for human review before publication.
Runs hypothesis-first proactive hunts against all ingested events to surface threats before they become alerts and suggests new detections for the catalog.
Direct integrations stream alerts and telemetry into the platform — you keep your stack, Critical Start handles the rest. Integration categories include EDR & Endpoint (CrowdStrike, SentinelOne, Microsoft MDE, Cortex XDR), SIEM & Data Lake (Splunk, Falcon NG-SIEM, Sentinel, Sumo Logic), Identity & Email (Entra ID, Microsoft MDO/XDR, Proofpoint, Abnormal), Network & Cloud (Palo Alto, Fortinet, Microsoft MDC, GuardDuty), and ITSM & Other (ServiceNow, Jira, Email, XSOAR). Daily inflow is 2.3M+ events per customer, all ingested and all addressable.
| Phase | What Happens | Agents / Human Checkpoints |
|---|---|---|
| 01 · Detect | Every alert hits the deterministic Trusted Behavior Registry first. Known-good signals clear automatically; everything else moves on. | TBR Agent resolves known-good behavior, reducing false positives deterministically. Threat Hunt Agent authors new detections from hunt outputs and coverage gaps. |
| 02 · Investigate | AI reasons over the alert. Case Agent finds related context; Investigation Agent builds the evidence chain. | Investigation Agent reasons over a single alert: enrichment, hypothesis, evidence. Case Agent intelligently aggregates related alerts for Agents and Analysts. Human checkpoint: SOC Analyst (Critical Start) validates the verdict — sign-off before any action lands in your environment. |
| 03 · Respond | Action is determined, never improvised. Sensitive containment is authorized by your team — through MobileSOC®. | Response Agent recommends deterministic containment: isolate, disable, kill ticket — no risk of AI plan drift. Automation Agent runs multi-step playbooks from repeat work, accelerating detection and response. Human checkpoint: You (Customer) authorize sensitive actions; push to MobileSOC® to approve, respond, or escalate. |
| 04 · Improve | Insights are validated by your TAM and your monthly Cyber Risk Review. Every closed case feeds the system; every closed case enriches TBR, detections, and automations. | AI Engineering Agent self-improving loop proposes prompt and skill edits for agents. Insights Agent surfaces cross-environment patterns: gaps, drift, repeat offenders. Human checkpoint: Your TAM (Critical Start) curates and delivers your monthly Cyber Risk Review; You + Your TAM validate posture coverage, recommended changes. |
Deterministic core, compounding feedback loop: Trusted Behavior Registry + Automation Catalog + Investigation Procedures. Every closed case enriches the registry. Every new playbook becomes deterministic. If AI is ever down, automations and people still run.
| Metric | What It Means |
|---|---|
| 99.83% | TBR Agent False Positive Resolution — every signal handled, no silent drops, no triage backlog. |
| <60 sec | Mean time to respond — sub-minute deterministic containment, with human authorization for sensitive actions. |
| 0 | Alert fatigue on your team — only true escalations; every other alert closes with full evidence. |
| 24/7 | MobileSOC® decisioning — authorize, escalate, respond from anywhere, full audit trail. |
| ∞ | Compounding coverage — every closed case enriches TBR, automations, and detections. |
| 100% | Resilient operations — if AI is unavailable, deterministic automations and analysts continue without disruption. |
