Compare Liminal vs. Permify

Liminal gives regulated organizations a single governed environment for AI. Rather than securing models an organization has already deployed, Liminal supplies the access itself, so protection is applied before anything reaches a provider. Employees work with leading models from Anthropic, OpenAI, Google and others through one interface, with policy-based routing and no per-provider contracts. Adding a new model becomes a policy decision rather than an integration project, and teams are never stuck waiting for procurement to catch up with what the market released. Sensitive terms are identified within each prompt and masked, redacted, flagged or blocked according to rules defined by data category rather than by department. Masked values are restored in the response, which keeps output usable while regulated information stays inside the organization. Employees never have to sanitize inputs by hand, which is what makes the governed path the one they actually choose. Administrators see who used which model, what rules were applied and where violations occurred. That record is generated at the time of the interaction, so audit requests are answered from existing evidence instead of reconstruction after the fact. Activity can be fed into existing security tooling and reviewed alongside other events rather than in isolation. The platform connects to internal systems through MCP, so employees bring organizational context into their work without moving data into tools nobody is watching. Access follows permissions that already exist. Deployments run on single-tenant infrastructure with SSO and role-based permissions, serving banking and credit unions, insurance, healthcare, education, state and local government, and life sciences.

Permify is an advanced authorization service tailored for developers looking to create and oversee detailed, scalable access control systems within their software applications. Drawing inspiration from Google's Zanzibar, it allows users to organize authorization models, store authorization data in chosen databases, and utilize its API for managing authorization queries across diverse applications and services. The service accommodates various access control models, such as Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC), which support the development of detailed permissions and policies. By centralizing authorization logic, Permify abstracts it from the core codebase, making it simpler to reason about, test, and debug. Additionally, it offers a range of flexible policy storage options and includes a role manager for managing RBAC role hierarchies effectively. The platform enhances efficiency in large, multi-tenant setups by implementing filtered policy management, ensuring that access controls are enforced seamlessly across different environments. With its robust features, Permify stands out as a comprehensive solution for modern access management challenges.
