Description

Cerbos serves as a comprehensive authorization management platform designed to establish, implement, and assess access control policies across various applications and services. It enables developers to utilize its policy decision point (PDP) for evaluating authorization requests, while teams can create and oversee policies based on roles, relationships, and attributes. Cerbos accommodates workflows that can be local, self-hosted, or cloud-based, providing features like policy testing, observability, and audit logs for scrutinizing authorization choices. Additionally, Cerbos Hub offers a managed setting for organizing and disseminating policies, and the open-source Cerbos PDP is suitable for deployment alongside application workloads. The platform is tailored for engineering, security, and product teams needing reliable and detailed authorization mechanisms for users, services, and other identities within distributed systems. In doing so, it enhances security and streamlines the management of complex access-control scenarios across diverse environments.

Description

Kastra serves as the crucial authorization framework for AI systems, determining the permissions of agents, models, and tools prior to their execution. Positioned along the execution path of all interactions such as prompts, tool calls, shell commands, database operations, and API requests, it evaluates each action based on deterministic, attribute-driven policies, rendering decisions to allow, deny, redact, or escalate in less than a millisecond. In contrast to monitoring solutions that only track AI actions post-execution, Kastra proactively prevents unauthorized activities before they can impact any tool, API, database, or production environment. Its comprehensive control plane integrates a policy engine, edge decision-making capabilities, various integrations, and a tamper-proof evidence vault that securely signs each decision for auditing and replay purposes. Furthermore, with Kastra Edge, local enforcement is extended to developer environments, safeguarding coding agents such as Claude Code, Cursor, and Codex CLI from harmful commands, unauthorized data extraction, unsafe file modifications, and improper tool usage. This proactive approach to authorization not only enhances security but also ensures compliance and accountability in AI-driven processes.
