Agentic Index
Radiant Security vs Simbian (2026)
Both vendors last verified
Radiant Security and Simbian both investigate alerts to a verdict and propose responses an analyst approves, and neither publishes a price. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Simbian covers more of the security program, and Radiant adds a log store to triage. Simbian runs SOC, pentest, threat hunting and network agents over one Context Lake, a persistent map of assets, identities and past verdicts, and measures itself against the customer's own objectives. Radiant pairs triage with integrated log management as a SIEM cost alternative. Choose Simbian for shared context and self testing, and Radiant for a bundled log store.
On the Agentic Index AI SOC ranking, neither Radiant Security nor Simbian clears the bar, which asks for all five investigation loop capabilities documented in full. Radiant Security does not document workflow orchestration in full, nor observability and auditability; Simbian does not document observability and auditability in full. 25 of the 86 vendors in the lane clear it.

Integrations & Tool Calling Ability to connect agents to real systems through native integrations, OAuth-authenticated actions, custom tools, APIs, webhooks, or MCP-compatible tools. |
||
|
Radiant SecurityIntegrations & Tool Calling Data connectors ingest from the customer's tools in categories that include authentication, cloud access security brokers, cloud, endpoint and network logs, email infrastructure and IAM, ICS and OT, messaging apps, password managers, SIEM tools, ticketing systems, security service edge, API protection and an S3 connector, and outgoing webhooks send data on. Response actions run from the case view in CrowdStrike, Microsoft 365 Defender, SentinelOne, Microsoft 365, Okta, Google Workspace, Mimecast, Proofpoint, Netskope and KnowBe4, isolating devices, disabling users, resetting passwords, ending sessions, deleting messages, removing external forwarding rules and blocking IPs, URLs, domains and files. They also start full disk scans in SentinelOne and enroll users in KnowBe4 phishing training.

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. |
||
|
Radiant SecurityWorkflow Orchestration Each alert runs through the product's own triage, investigation and case sequence, and response actions launch from the case, on one artifact or in bulk across selected users, IPs and URLs. The audit log mentions automated playbooks, but Radiant describes no branching, multi agent handoff or automation the customer configures.

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. |
||
|
Radiant SecurityTriggers & Channel Coverage Alerts arriving through data connectors or the custom alerts webhook are triaged and investigated automatically, with no analyst starting the work. Webhook alerts are posted as JSON with a token, enter the triage pipeline and become searchable within several minutes.

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.

|
Radiant SecurityKnowledge Grounding & RAG Integrated log management stores the customer's logs with search, query and retention settings, and alerts sent through the custom webhook land in its parsed and alert indexes, where teams can search and investigate them. Radiant says the platform continuously learns the environment, its tooling, behavior and activity to boost accuracy, but it does not say how investigations draw on what it has learned or on the customer's own documentation.

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. |
||
|
Radiant SecurityMemory & State Persistence The platform continuously learns about the environment, its tooling, behavior and activity to boost accuracy, by Radiant's account, but Radiant describes no memory store, what it would keep, its scope or its lifetime. SourceRadiant Security, radiantsecurity.ai and help.radiantsecurity.airead 2026-10-06 |
||
|
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. |
||
|
Radiant SecurityHuman Oversight & Guardrails Response actions launched from a case run when an analyst selects the targets, clicks the action and confirms the list of affected artifacts in a confirmation step, and many can be reversed with one click from the action history through the inverse action, such as enabling a user again. Hard deletes and password resets cannot be undone. The platform produces incident specific response plans for that analyst to execute. The audit log separates analyst actions from automated platform actions and playbooks, and Radiant does not say which actions, if any, run without that confirmation.

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 |
