Agentic Index
Prophet Security vs Simbian (2026)
Prophet Security and Simbian both investigate every alert and both test their own behavior against the customer's data, which few in the lane document. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
They sit close on the grid, 8.5 and 9 of 14. Prophet runs an analyst, a threat hunter and a detection engineer that backtests detections before they ship, records every query and reasoning step, and sells a human review service beside the software. Simbian runs SOC, pentest, threat hunting and network agents over one shared Context Lake and scores itself against the customer's own objectives. On the grid Prophet is Full on observability and Partial on security where Simbian is Partial and None; Simbian is Full on deployment, knowledge grounding and workflow orchestration where Prophet is Partial. Choose Prophet for auditable investigations and detection engineering; choose Simbian for a broader agent family with shared context.
On the Agentic Index AI SOC ranking, neither Prophet Security nor Simbian clears the bar, which asks for all five investigation loop capabilities documented in full. Prophet Security does not document workflow orchestration in full; Simbian does not document observability and auditability in full. 23 of the 85 vendors in the lane clear it. See the AI SOC ranking
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Prophet Security and Simbian are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 955 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Prophet Security if
- Every step behind a determination must be on the record; Prophet is Full on observability and Simbian Partial.
- Detection engineering with backtested detections is part of the job.
- A vendor human review service should sit beside the software.
Choose Simbian if
- Pentest and network agents should share memory with the SOC agent.
- Grounding in an organization wide asset and identity map matters; Simbian is Full there and Prophet Partial.
- Deployment and data residency must be documented in full.

Integrations & Tool Calling Ability to connect agents to real systems through native integrations, OAuth-authenticated actions, custom tools, APIs, webhooks, or MCP-compatible tools. |
||
|
Prophet SecurityIntegrations & Tool Calling More than 200 integrations come out of the box, and the AI SOC Analyst responds through scoped, permissioned Agent Actions in the customer's systems, from notifications to quarantining a machine. Results are delivered to Slack, Teams or the customer's own webhook. Investigations query SIEM, EDR, identity, cloud and email tools, and delivery can be set separately for each channel.

SimbianIntegrations & Tool Calling Simbian reads more than 100 integrated sources (SIEM, EDR, XDR, identity, CVE feeds, firewall rules, ITSM) and writes back into the customer's tools, with response actions in EDR, cloud and Active Directory, detection rules in the SIEM's own query language, WAF and firewall rules, and ITSM tickets. Sources also include CDR tools, bug databases, threat hunts and pentest reports. SourceSimbian, simbian.ai and /self-improving-defenseread 2026-10-05 |

|
Workflow Orchestration Ability to sequence, branch, retry, route, and combine deterministic workflow nodes with autonomous agent steps. |
||
|
Prophet SecurityWorkflow Orchestration Each alert runs through a fixed investigation, determination and response sequence, and customers can add guidance to a single step. There is no branching, conditions, handoff between agents or workflow that customers build. Related investigations are grouped into incidents automatically. SourceProphet Security, prophetsecurity.ai/ai-soc-analystread 2026-10-05 |
||
|
SimbianWorkflow Orchestration Several agents hand work to each other: when alerts cluster on an application the SOC Agent launches a pentest, and the proven exploit becomes a detection rule, a WAF rule, a network firewall rule and a patch ticket, with SOC, Pentest, Threat Hunt and NetSecOps agents sharing one Context Lake. One alert can produce a response, a tighter detection, a closed attack path, or a false positive tuned down for good. Simbian describes the loop as seeing a threat, investigating, responding, scoring its own work and proposing a better version of itself.

Triggers & Channel Coverage How agents wake up and where they work: schedules, webhooks, message events, CRM events, inbox events, chat, email, voice, and collaboration tools. |
||
|
Prophet SecurityTriggers & Channel Coverage Alerts are investigated the moment they arrive, 100 percent of them at every severity, with no analyst starting the work. Each investigation begins by summarizing the alert, pulling out its artifacts and planning the questions an expert analyst would ask. SourceProphet Security, prophetsecurity.ai/ai-soc-analystread 2026-10-05 |
||
|
SimbianTriggers & Channel Coverage Work starts without a person asking: every alert is investigated on arrival, clustered alerts launch a pentest, and vulnerability feeds and peer breach reports start agent work. The SOC Agent begins the instant an alert is detected and reaches a response in under 4 minutes on average.

Knowledge Grounding & RAG Ability to ground agent behavior in company data through document ingestion, retrieval, external knowledge APIs, semantic search, or RAG layers. |
||
|
Prophet SecurityKnowledge Grounding & RAG Investigations gather evidence live across the customer's connected tools and apply the guidance the customer writes. There is no index, graph or embeddings layer over the customer's own knowledge. The AI Detection Engineer maps the customer's MITRE ATT&CK coverage from its own investigations. SourceProphet Security, prophetsecurity.ai/ai-soc-analyst and prophetsecurity.airead 2026-10-05 |

SimbianKnowledge Grounding & RAG Context Lake is an organization wide, persistent map of the customer's assets and identities built from more than 100 sources, including SIEM, EDR, identity, CVE feeds, pentest reports, firewall rules and ITSM runbooks, which every agent queries. It stays in the customer's tenant. It also holds every past verdict, so a new investigation starts from what earlier ones found. SourceSimbian, simbian.ai and /products/ai-soc-agentread 2026-10-05 |

|
Memory & State Persistence Ability to persist context across a run, conversation, workflow, user, team, or longer-term memory layer. |
||
|
Prophet SecurityMemory & State Persistence Customers teach the agent playbooks, policies and preferences in plain language, organization wide, per investigation or per step. Nothing is learned silently, and every entry's source is visible and correctable. What the agent learns carries into every later investigation and stays when an analyst leaves. Most entries are guidance the product applies, and Prophet does not say how long they are kept. SourceProphet Security, prophetsecurity.ai/ai-soc-analystread 2026-10-05 |
||
|
SimbianMemory & State Persistence Every alert the SOC Agent closes is written back to the shared Context Lake, an organization wide persistent memory the other agents read, so they start with prior context instead of starting cold. Simbian does not say how long that memory is kept or how to delete anything from it. SourceSimbian, simbian.ai/products/ai-soc-agent and simbian.airead 2026-10-05 |

Human Oversight & Guardrails Approval steps, consent checkpoints, escalation rules, structured guardrails, policy constraints, and pause/resume controls. |
||
|
Prophet SecurityHuman Oversight & Guardrails Agent Actions run autonomously or only with the customer's sign-off, each remediation is previewed before it runs, and actions are scoped and permissioned. Autonomy covers only the actions a customer has approved, and the customer widens that scope when the agent's track record justifies it. Watchtower experts also review every malicious determination around the clock. SourceProphet Security, prophetsecurity.ai/ai-soc-analyst and prophetsecurity.airead 2026-10-05 |

|
SimbianHuman Oversight & Guardrails The customer's analysts approve the responses Simbian proposes, and Simbian reports that 95 percent are approved. Before the agents change their own skills, Simbian shows the change and its evidence, and the customer approves before anything is applied. Every action passes through a gate and can require approval, and customers lift gates one action type at a time on their own schedule. Anything that touches an employee, and anything destructive, stays gated permanently. SourceSimbian, simbian.ai/self-improving-defenseread 2026-10-05 |

Prophet SecurityTesting, Debugging & Optimization Changes to the agent's guidance are previewed and backtested against the customer's own alert history before they apply, so a change has to hold up on past alerts first. Remediations and new detections are backtested the same way. One customer reports 95% less manual review, and Prophet cites a 10 times faster MTTR.

SimbianTesting, Debugging & Optimization Simbian builds a test for a customer authored objective, scores itself on the customer's own data and shows which cases fell short and why, and proposed changes to its skills are shown with evidence for approval before they apply. It checks itself constantly where it is unsure and rarely where it is confident. Customers write objectives such as never paying a ransom, keeping a production line running or answering every alert.
