Try Simbian
Overview
Simbian's bet is that the interesting unit is not a single AI analyst but a set of agents covering different security functions that share the same understanding of your organisation. A SOC agent triages alerts from your SIEM and XDR; a threat hunting agent works threat intelligence feeds against your environment looking for indicators; a GRC agent handles security questionnaires and vendor assessments. Three jobs, one context.
That shared context is the architectural idea, marketed as the Context Lake: your own standard operating procedures, entity data and accumulated analyst feedback, which every agent reasons over. The claim it supports is meaningful — the company reports its SOC agent auto-resolving 92% of alerts in 2026 production deployments — and it explains why: an agent that knows your procedures and has learned from your analysts' corrections should outperform one reasoning from generic security knowledge.
It emerged from stealth with $10 million in seed funding, which makes it the smallest of the serious AI SOC vendors by some distance. The GRC coverage is genuinely differentiated — questionnaires and vendor assessments consume enormous amounts of security team time and almost nobody is automating them well — but a $10 million company is a different risk proposition from one that raised $125 million.
Key Features
Multiple Coordinated Agents
SOC triage, threat hunting and GRC agents that share one understanding of your organisation rather than three disconnected tools.
Context Lake
Agents reason over your own procedures, entity data and analyst feedback, which is why performance improves as the deployment matures.
High Autonomous Resolution Rate
Reported 92% of alerts auto-resolved in 2026 production deployments — a figure worth validating against your own alert mix during a trial.
Threat Hunting Agent
Processes threat intelligence feeds and hunts indicators of compromise across the environment rather than waiting for an alert.
GRC Automation
Security questionnaires and vendor assessments handled by an agent — a real time sink that almost no competitor addresses.
Analyst Feedback Loop
Corrections from your analysts feed back into the Context Lake, so the system adapts to how your team actually works.
Pros & Cons
Advantages
- Covers SOC, hunting and GRC rather than triage alone
- Context Lake makes agents improve with your team's feedback
- GRC automation addresses a genuine and widely ignored time sink
- Strong reported auto-resolution figures in production
- Unified reasoning across offensive and defensive context
Disadvantages
- $10M seed makes it the smallest serious vendor in this category
- The 92% figure needs validating against your own alert mix
- Breadth across three functions risks less depth in each
- Smaller installed base and support organisation
Pricing Plans
| Plan | Price | Key Features |
|---|---|---|
| Enterprise | Custom | Priced on agent scope, alert volume and deployment size |
Best Use Cases
Simbian Excels At:
- Small security teams covering SOC, hunting and compliance with the same people
- Organisations drowning in security questionnaires and vendor assessments
- Environments with documented procedures the Context Lake can learn from
- Teams wanting one vendor across several security functions
May Not Be Ideal For:
- Large enterprises needing maximum depth in alert triage specifically
- Buyers for whom vendor size and continuity are primary criteria
- Organisations without documented procedures to ground the agents
How It Compares
Simbian vs Dropzone AI
Dropzone is deeper on alert investigation with a much larger installed base; Simbian is broader, covering hunting and GRC as well. A large SOC should probably prefer depth. A three-person security team covering everything may get more from breadth.
Simbian vs Prophet Security
Both are young, venture-backed and focused on autonomous security work. Prophet concentrates on investigation methodology; Simbian spreads across three functions with shared context. Funding and installed base favour Prophet; scope favours Simbian.
Final Verdict
Our Recommendation
Simbian is the most interesting bet in the agentic security field and the highest risk of the credible options. The Context Lake idea is right — agents reasoning over your own procedures and learning from your analysts should beat generic security reasoning — and extending agents into GRC addresses a real time sink nobody else takes seriously. It is also a $10 million seed-stage company competing against vendors that raised ten times that. Validate the auto-resolution claim against your own alerts, and weigh vendor continuity honestly for a tool you would be trusting with alert closure.
