Oso Security

PaaS providing software authorization features

Overview

Oso Security provides an authorization platform that helps software developers implement and manage user roles and permissions in their applications. Developers integrate Oso’s libraries into their code to define access rules, while the platform handles the underlying authorization logic; it can be used as Oso Cloud or Oso On-Premises. Its focus on developer-friendly authorization tooling and the option to deploy in the cloud or on-site set it apart from broader security suites that require more integration effort. Its goal is to make access control accurate and scalable, reduce security risks, and speed up software development by eliminating the need to build custom authorization logic.

Simplify's take

What believers are saying

  • Temporal’s $550 million September 2026 raise funds aggressive agent-security integration.
  • AWS Marketplace distribution reduced buying friction for Oso customers like Leaflink.
  • March 2026 research and January 2026 coding-agent launch validated urgent market demand.

What critics are saying

  • October 6, 2026: Tiny acquired Oso Cloud, and most employees joined Temporal.
  • Oso’s standalone product momentum ended when the team shifted into Temporal’s roadmap.
  • If agent-authorization demand stalls, Oso loses independent revenue and brand relevance.

What makes Oso Security unique

  • Oso standardized authorization for developers before policy sprawl became a crisis.
  • Its AWS Marketplace listing and ISV Accelerate status strengthened enterprise procurement.
  • March 2026 research quantified 96% unused permissions, sharpening its agent-security thesis.

Temporal acquires Oso team to build agent authorization after raising $550M

Temporal has acquired the team behind Oso to build agent authorisation into its execution platform. The move addresses a critical security challenge as AI agents gain access to business-critical systems and data. Research shows 96% of permissions go unused by human employees who exercise judgement, but agents lack this restraint. Temporal's platform already powers agents for OpenAI and Cursor, processing over 5 billion actions monthly across 500 namespaces at Netflix alone. The Oso team will help Temporal implement fine-grained access controls that survive the crashes and retries inherent in production environments. Graham Neray, Oso's founder, said agents' value and danger both stem from their system access, requiring precise developer controls. The announcement follows Temporal's September 2026 Series E funding round, which raised $550 million.
