Radiant reads every alert the way a tier-1 analyst would, then hands back the one to three that actually matter. The pitch is a no-playbook approach across a dozen attack surfaces (email, endpoint, identity, cloud, SIEM, WAF, DLP, OT/IoT and more) plus a cheap log tier at $23/TB that lets teams peel workloads off an expensive SIEM. Users report noise dropping in the first week without months of tuning, which is rare in this category. The caveats are the usual for a young autonomous-SOC product: verdicts still throw false positives, some hand-holding from Radiant's team is expected, and pricing is flat-rate but sales-led with nothing self-serve. Best for mid-to-large SOCs and MSSPs that want fixed-cost triage; not a fit for a small team wanting to swipe a card and start. Validate the accuracy claims against your own alert mix before you lean on it.
What people say
Founded in 2021 by Shahar Ben-Hador (former Imperva CISO) and Barry Shteiman, Radiant helped coin the "AI SOC" category and now competes with a crowded field of agentic-triage vendors. It's backed by DCVC, Lightspeed and Siemens' Next47, with a $15M Series A in November 2023 and a larger Series C led by DCVC in November 2024. In 2026 it picked up recognition in the Hacker News Cybersecurity Stars Awards for SOC automation.
The headline number Radiant markets is up to 98% false-positive reduction, with only one to three high-fidelity alerts surfaced per analyst per day. Coverage spans email, endpoint, identity, network, cloud, insider threat, SIEM, WAF, DLP, OT/IoT, dark web and supply chain, and every investigation produces an audit trail showing what was analyzed and why the AI closed or escalated it.
Early reviews on Gartner Peer Insights, Software Advice and Capterra skew positive. One buyer called it "the most accurate agentic SOC we've seen, with investigations going significantly deeper than anything else we looked at." Another flagged the speed to value: "immediate operational impact in the first week... the closest thing I've seen to plug and play automation in this space."
The recurring reservation is maturity. Reviewers note that because the product is young, there are still false positives and a tuning period alongside the Radiant team before trust is fully earned. That's less a knock than a reminder that autonomous triage is a trust exercise, not a switch you flip.
Commercially, Radiant leans on flat-rate pricing with no per-alert or per-ingestion charges, which appeals to MSSPs that need predictable client-monitoring costs, and the $23/TB logging option is aimed squarely at teams trying to cut SIEM bills. There's no published plan sheet and no free tier, so budgeting means a sales conversation. For regional buyers there's no documented ASEAN presence or data-residency detail, so confirm support and hosting directly.
