Cerbos vs Oxide Computer
Side-by-side comparison of AI visibility scores, market position, and capabilities
Cerbos is an open-source authorization platform that externalizes and centralizes access control logic, eliminating authorization code scattered across application services.
About
Cerbos is an open-source authorization solution founded in 2021 that provides a centralized policy decision point for application access control, allowing engineering teams to define, manage, and test authorization logic independently of application code. The platform uses a human-readable YAML policy language to define roles, permissions, and conditions, and exposes a simple API that microservices query to determine whether a user can perform a given action on a given resource. Cerbos addresses the problem of authorization logic becoming complex and fragmented as applications grow, typically spread across database queries, middleware, and application code in ways that are hard to audit, test, or modify. The company raised $7.5M in seed funding and offers a SaaS managed platform called Cerbos Hub for teams that want hosted policy management and audit logging. Cerbos is used by engineering teams at technology companies building multi-tenant SaaS products where fine-grained permission models are required. The platform supports attribute-based access control (ABAC), role-based access control (RBAC), and relationship-based access control patterns, making it flexible enough for complex enterprise authorization requirements.
Oxide Computer raised $200M Series C in February 2026 for its rack-scale private cloud server that ships full-stack hardware and software as a single appliance.
About
Oxide Computer builds the first commercially available cloud computer — a rack-scale system that integrates hardware, firmware, and software into a single appliance enabling enterprises to run private cloud infrastructure without the complexity of hypervisor stacks. The Oxide Rack ships as a fully integrated unit with built-in networking, storage, and compute managed through a unified control plane. This eliminates the fragmented vendor ecosystem that makes on-premises cloud difficult to operate.
