Agentic Index
Prophet Security vs Radiant Security (2026)
Prophet Security and Radiant Security both investigate alerts at every severity and neither publishes a price. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Prophet is built around auditable investigations, and the ownership picture differs: Cribl acquired the technology behind Radiant's product in August 2026, though Radiant's site still sells it. Prophet runs an analyst, a threat hunter and a detection engineer, records every query and reasoning step behind a determination, and deploys as a dedicated single tenant with a bring your own key option. Radiant pairs triage with integrated log management as a SIEM cost alternative. On the grid Prophet is Full on observability, prebuilt agents and testing where Radiant is Partial or None; Radiant is Full on its API where Prophet is None. Choose Prophet for auditable investigations and tested guidance; choose Radiant if its log store changes your SIEM math and the Cribl transition suits you.
On the Agentic Index AI SOC ranking, neither Prophet Security nor Radiant Security clears the bar, which asks for all five investigation loop capabilities documented in full. Prophet Security does not document workflow orchestration in full; Radiant Security does not document workflow orchestration in full, nor observability and auditability. 23 of the 85 vendors in the lane clear it.

This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Prophet Security and Radiant Security 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 query and reasoning step behind a verdict must be auditable; Prophet is Full on observability and Radiant Partial.
- Guidance changes should be tested against your own alert history before they go live.
- A dedicated single tenant with your own key is a requirement.
Choose Radiant Security if
- Integrated log management could stand in for part of your SIEM.
- You need API access to the platform; Radiant is Full and Prophet None.
- The product running on Cribl's telemetry platform suits your stack.

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.

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.

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.

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.

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.

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.

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.

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 |

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 |
||
|
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.
