Prophet Security vs Radiant Security
Prophet Security
Prophet Security builds an agentic AI SOC platform whose main component, Prophet AI SOC Analyst, autonomously triages, investigates and responds to security alerts, alongside an AI Threat Hunter and an AI Detection Advisor aligned to MITRE ATT&CK. The platform shows its full reasoning, investigation plans, queries and evidence for each investigation. It deploys by taking read-only API access to existing tools such as SIEM, identity providers, cloud platforms and EDR, and returns results in an investigation workbench. The company was co-founded by Kamal Shah and Vibhav Sreekanti, whose prior company StackRox was acquired by Red Hat.
Pros
- Raised a $30M Series A led by Accel with participation from Bain Capital Ventures, following an $11M seed led by Bain Capital Ventures (Pulse2, Help Net Security)
- Founders' prior company StackRox was acquired by Red Hat (company blog)
- Company reports over 1 million investigations conducted and 360,000 analyst hours saved in a six-month period (Pulse2, company-reported)
- Docker is a named customer with an executive quote in funding coverage (Pulse2)
Things to check
- Pricing is not published; prospective buyers need to request a quote
- Headline metrics such as 10x faster response and 96% fewer false positives are company-reported rather than independently audited
- The company emerged from stealth in April 2024, so long-term production references are still limited

Radiant Security
Radiant Security is an AI SOC platform that triages and investigates security alerts across sources including endpoint, identity, cloud, email, network, and SIEM, then escalates what it assesses as real threats to analysts with documented reasoning. The vendor states analysts can execute response actions from within the platform, and an integrated log management option stores data in the customer's own S3 bucket. It deploys as cloud-hosted SaaS and connects to existing tools through API-based integrations, which press coverage of its Series A described as deployable in minutes.
Pros
- Press coverage of the Series A reported API-based deployment in minutes, with a customer escalating a real threat within two hours of installation (SiliconANGLE)
- Vendor states every AI conclusion includes transparent reasoning and a full audit trail
- Raised a $15M Series A led by Next47 with participation from Lightspeed, Acrew, and others in November 2023 (SiliconANGLE, SecurityWeek)
Things to check
- No public pricing; the vendor describes a flat-rate subscription but figures require a sales conversation
- Cloud-hosted SaaS delivery, so review data residency and log storage requirements
- Founded in 2021 with $15M in disclosed funding, so apply standard early-stage vendor diligence
