Legion Security vs Intezer
Legion Security
Legion Security helps enterprise security teams scale detection, investigation and response using agentic AI. The platform captures and learns from the real workflows analysts already use, and turns those actions into agentic playbooks the team can trust. The vendor positions this as a way to adopt frontier AI models gradually while keeping operational trust, reducing manual effort and preparing for autonomous security capabilities. It deploys through the analyst's browser rather than through API integrations, and uses vision models combined with other methods to observe how analysts investigate alerts, so the enterprise can either codify those processes or optimise them into visual agentic workflows that the team can inspect. Legion Security has offices in New York and Tel Aviv and is backed by Coatue, Accel and Picture, with investors from Island, CrowdStrike, Wiz and Google DeepMind. The company was founded in 2024 by former Microsoft Sentinel team members and emerged from stealth in July 2025.
Pros
- Raised $38M total: an $8M seed led by Picture Capital and Accel, and a $30M Series A led by Coatue (Calcalist, Fortune)
- Founding team includes former members of Microsoft's Sentinel product, per Calcalist
- Browser-based deployment is designed to avoid custom API integration work, per the company
- Customers cited on the vendor site report outcomes such as an 81% reduction in MTTI/R (WELL Health Technologies, vendor-cited)

Intezer
Intezer is an AI SOC platform that automatically investigates and triages alerts from endpoint, SIEM, phishing, identity, and cloud sources, resolving what it judges to be false positives and escalating a small share to analysts with findings and recommended actions. Its triage applies techniques from the company's malware analysis background, including memory scanning, code reverse engineering, and integrated threat intelligence. The platform deploys as cloud-hosted SaaS with more than 100 integrations and serves enterprise SOC teams and MSSPs.
Pros
- Technology heritage in malware analysis and threat forensics, which investor Norwest describes as a data moat for its AI SOC product
- Customers report alert investigation about 60 times faster than manual analysis, with roughly 4 percent of alerts escalated to the SOC (reported in Norwest's investor writeup)
- Operating since 2015, with a $33M Series C led by Norwest and roughly $68M in total disclosed funding (Pulse2, Tracxn)
