Overview

Straiker builds an agentic-native security platform for enterprises and frontier AI labs. The product discovers AI agents across environments, runs pre-deployment adversarial testing through STAR Labs, and applies runtime protection that feeds production threats back into testing. Co-founded by Ankur Shah (ex–Palo Alto Networks Prisma Cloud) and Sreenath Kurupati (ex–Akamai / Cyberfend). In June 2026 Straiker raised a $64 million Series A (total funding $85M) led by Marathon Management Partners, Citi Ventures, Illuminate Financial, and Workday Ventures, with Bain Capital Ventures and Lightspeed returning.

Why Straiker is interesting

Series A ($64M, Jun 2026) with Bain Capital Ventures and Lightspeed returning plus Workday/Citi strategics — agent security is becoming its own enterprise control plane as agents get production credentials.

Competitive landscape

Edge: Founders scaled Prisma Cloud and AI/security research; pairs exploit research (STAR Labs) with an agent-native runtime engine sold to Fortune 500 and frontier labs.

As agents gain tools and identity, security buyers need discovery + adversarial test + runtime — not prompt filters alone. Straiker sells that full loop.

• Zenity adjacent

  AI agent security/governance; overlapping enterprise buyer.

• Neo (agentic security) adjacent

  Agent security category peer in 2026 funding wave.

• Classic CNAPP / CSPM incumbent

  Cloud posture tools not built for dynamic tool-using agents.
