Vega

Vega Security builds what it calls a "post-SIEM" cyber-defense platform, replacing the manual dashboards and static rules of traditional Security Information and Event Management tools with AI agents that search, detect, and investigate on their own. Its Agentic Search lets analysts query all their security data in plain language; Agentic Detection writes and self-tunes detection rules; and Agentic Triage & Investigation turns raw alerts into decision-ready cases without a human working each one manually. Underneath, Vega queries data where it already lives (federated analytics, no data movement required) and exposes itself to AI clients via MCP for "headless" integration into a security team's existing tools. The company claims it can process a billion logs in under a minute and cut noise by over 90%, at a fraction of legacy SIEM cost. It operates as two linked entities — Vega Cyber Solutions in Tel Aviv and Vega Security Inc. in New York — and counts a top-4 US bank and a luxury retail group among its named customers, with the bank's own security engineers citing a rollout measured in weeks rather than the usual multi-quarter SIEM migration.
