Radiant Security
Radiant Security is an agentic AI SOC platform that triages 100% of your security alerts with transparent, auditable reasoning.
Radiant's pitch — triage 100% of alerts, explain every verdict, keep logs in your own S3 bucket — is aimed squarely at teams whose real problem is volume, not tooling gaps. The June 2026 public REST API removes one of the more common buyer objections, since automation no longer has to live inside Radiant's UI. The catch: pricing isn't public and the model is flat-rate plus a buyout program, so the numbers only make sense once you've benchmarked them against your current MSSP or SOAR spend.

Skip Radiant Security if you require on-prem or air-gapped deployment, have a very low alert volume (under 100 alerts/day), or prefer a fully self-managed, open-source security stack without any vendor dependency.
Pricing is quote-only, so you may need to engage with sales to get a figure; there is no self-serve tier.
Radiant's flat-rate pricing is tailored for mid-to-large security teams and MSSPs that need high-volume triage without unpredictable per-seat or per-alert fees. Compared to legacy SOAR solutions that charge per automation run or SIEMs with data ingestion costs, Radiant's model may offer cost predictability, but without public pricing, smaller teams may find it less accessible than transparently-priced alternatives like Tines or Torq.
In short
Radiant Security — Radiant Security is an agentic AI SOC platform that triages 100% of your security alerts with transparent, auditable reasoning. Best for SOC teams drowning in alert volume that need 100% triage without adding headcount, MSSPs delivering end-to-end SOC automation across multiple isolated customer tenants, Security leaders who need explainable, auditable AI decisions for incident review.

About Radiant Security
Radiant Security is an agentic AI SOC platform built for security operations teams that need to investigate every alert, not just a sampled subset. It automates alert triage, investigation, and response across email, endpoint, identity, cloud, SIEM, WAF, and DLP telemetry, generating or reusing response plans for both known and unknown alert types. The stated goal is eliminating up to 98% of noise while escalating only validated threats. Every AI verdict ships with transparent reasoning and a full audit trail, so an analyst can trace any decision back to the raw data behind it. Radiant also includes Log Manager, a built-in security data lake that stores unlimited logs in your own S3 bucket, which keeps retention costs and lock-in under your control rather than the vendor's. Around 100 plug-and-play API connectors and multi-tenant support with isolated tenancy make it usable for MSSPs running separate customer environments. Recent additions matter here. In June 2026 Radiant shipped a public REST API that enables programmatic read and action on data from external UIs, so automation is no longer confined to the product's own interface. The same month, The Hacker News recognized Radiant as the AI SOC platform with the highest triage fidelity in its Best SOC Automation Solution category. Positioning-wise, Radiant sits against legacy SOAR built on playbooks and pre-configured rules, and against MDR/MSSP contracts that outsource the same triage work. It targets lean SOC teams and MSSPs that want full coverage without proportional headcount growth, with customizable AI thresholds and a Night Shift Analyst option for after-hours alerts. Pricing is not published.
Behind the Verdict
The interesting thing about Radiant isn't the word 'agentic' — half the SOC market is using it now. It's the claim of 100% alert triage with reasoning you can audit. Most automation in this category quietly reduces coverage: you route the easy stuff to a playbook and the rest still lands on an analyst. If Radiant genuinely investigates every alert and shows its work, that changes the math on how many analysts a shift needs. Pick Radiant if alert volume is your bottleneck and you're willing to let AI make first-pass calls, provided the audit trail satisfies your compliance and IR requirements. The transparent reasoning matters more than the marketing suggests — in a real incident review, 'the model said so' does not survive scrutiny. Being able to trace a verdict to raw data is what makes an AI triage decision defensible to a CISO or an auditor. The June 2026 REST API is the update I'd weigh most. Before it, automation around Radiant meant living in Radiant's UI or its connector set; a public API for programmatic read and action means you can wire triage and response into your own tooling, ticketing flows, or a customer-facing portal. For MSSPs especially, that's often the difference between a platform being adoptable and being a walled garden. Log Manager deserves a look for a less obvious reason: storing unlimited logs in your own S3 bucket. Log retention is where a lot of SOC budgets quietly hemorrhage, and keeping the data in your account changes both the cost curve and your exit options if you ever leave. Where it bites: pricing isn't published, so you can't sanity-check fit before a sales conversation. The flat-rate model and buyout program are attractive against per-GB or per-seat legacy contracts, but only if your volume is high enough to make flat-rate the

Real-world workflow fit
Concrete scenarios for the personas Radiant Security actually fits — and what changes day-one when you adopt it.
Day one: Connect your SIEM (e.g., Splunk) and email gateway. Radiant begins triaging all incoming alerts, providing a prioritized queue with AI-reasoned verdicts.
Outcome: You focus only on escalated true positives, cutting noise by up to 98% and reducing MTTR.
Set up isolated client tenancies, each with its own connectors and policies. Use the buyout program to migrate from a traditional MSSP contract.
Outcome: You automate triage across all clients, scale without adding analysts, and maintain strict isolation.
Leverage the public REST API to trigger actions from external UIs, such as a custom ticketing system or a SOAR playbook.
Outcome: You extend automation beyond Radiant's native workflow, orchestrating response across your entire stack.
Use Cases
- Automatically triage and investigate every SIEM alert without analyst involvement
- Respond to confirmed threats with one-click or automated playbooks—no custom scripting needed
- Enrich alerts with threat intelligence from integrated feeds to speed up decision-making
- Centralize logs from all sources into a single searchable data lake with unlimited retention
- MSSPs can automate SOC operations for multiple clients with isolated tenancy and a buy-back program for switching
- Reduce analyst fatigue and improve MTTD/MTTR with AI-driven investigations
- Cover after-hours alerts consistently with the Night Shift Analyst solution
Limitations
- Radiant's main constraints are its cloud-only deployment (no on-prem or air-gapped environments) and lack of public pricing—you must contact sales for a quote.
- While the integration list is extensive (100+), very niche or legacy tools may not be supported out of the box.
- Organizations with extremely low alert volumes may not see sufficient ROI.
- Also, because the platform is AI-driven, some teams may need time to build trust in the AI's decisions, even with transparent reasoning.

Where the pricing makes sense
The company stage and team size where Radiant Security's pricing actually pencils out — and where peers do it cheaper.
Radiant's flat-rate pricing is tailored for mid-to-large security teams and MSSPs that need high-volume triage without unpredictable per-seat or per-alert fees. Compared to legacy SOAR solutions that charge per automation run or SIEMs with data ingestion costs, Radiant's model may offer cost predictability, but without public pricing, smaller teams may find it less accessible than transparently-priced alternatives like Tines or Torq.
Setup time & first value
How long it actually takes to get something useful out of Radiant Security — broken out by persona, not the marketing-page minute.
For a standard SIEM integration (e.g., Splunk or Elastic), expect to be triaging alerts within a day. MSSP multi-tenant setup may take a few days to configure isolated environments. The public REST API can be integrated within hours for engineers familiar with the platform's data model.
