What are On-Premises AI Agent Authentication Platforms?
AI agent authentication platforms help organizations securely identify, authenticate, authorize, and manage autonomous AI agents as they interact with enterprise applications, APIs, databases, cloud services, and other digital resources. These platforms provide identity and access management capabilities specifically designed for AI agents, enabling businesses to verify agent identities, control permissions, manage credentials, and enforce security policies across agent-driven workflows. AI agent authentication platforms often include features such as non-human identity management, machine-to-machine authentication, OAuth 2.0 and OpenID Connect integration, token management, secrets management, delegated authorization, least-privilege access controls, agent identity verification, and audit logging. Many solutions integrate with identity and access management (IAM) systems, API gateways, Model Context Protocol (MCP) servers, AI agent frameworks, cloud infrastructure, and zero trust security platforms to establish trusted communication between AI agents and enterprise systems. By providing centralized authentication and access governance for autonomous agents, these platforms help organizations prevent unauthorized access, protect sensitive information, reduce credential-related security risks, maintain regulatory compliance, and securely scale AI agent deployments.

Silverfort
Silverfort
Silverfort’s Unified Identity Protection Platform is the first to consolidate security controls across corporate networks and cloud environments to block identity-based attacks. Using innovative agentless and proxyless technology, Silverfort seamlessly integrates with all existing IAM solutions (e.g., AD, RADIUS, Azure AD, Okta, Ping, AWS IAM), extending coverage to assets that could not previously have been protected, such as legacy applications, IT infrastructure, file systems, command-line tools, and machine-to-machine access. Our platform continuously monitors all access of users and service accounts across both cloud and on-premise environments, analyzes risk in real time, and enforces adaptive authentication and access policies. -

Scalekit
Scalekit
Scalekit is the MCP gateway for AI agents. It is for developers and platform teams who need an agent to call tools as the user, not through a shared service account. One endpoint reaches 600+ connectors and 35,000+ tools, including Salesforce, Gmail, Slack, Notion, HubSpot, Jira, and GitHub. Scalekit finds that user's credentials, checks permission, runs the call, and returns a clean response. Tokens stay in an AES-256 vault. It works with Anthropic, OpenAI, LangChain, Google ADK, Vercel AI, and Mastra. Run it in the Scalekit cloud (US, with EU residency available), in your VPC, or self-hosted. SOC 2 Type II and ISO 27001. A HIPAA BAA is available on Enterprise. The Free plan includes 10,000 tool calls and 10,000 trigger events a month. Growth is $99 a month for 100,000 tool calls. Enterprise pricing is custom.Starting Price: $99/month -

Cerbos
Cerbos
Cerbos is an authorization management platform. Teams use it to authorize every identity, govern every action and prove every decision, with fine-grained, contextual and continuous authorization across applications, gateways, workloads and AI agents. Access rules live in readable policies instead of application code, so security and product teams can change who can access what without waiting for an engineering release. Cerbos supports RBAC, ABAC, ReBAC and PBAC, reads roles and attributes from your identity provider and databases when each check runs, and checks every AI agent action against the same rules as people. Every access check is logged with the policy that applied, ready for SOC 2, ISO 27001 and HIPAA audits. Cerbos runs hosted, self-hosted or air-gapped. Utility Warehouse, 9fin, 4G Capital, VW, Human Managed, and thousands of other organizations use Cerbos in production.Starting Price: $25/month -

Arcade
Arcade.dev
Arcade.dev is an AI tool-calling platform that enables AI agents to securely perform real-world actions, like sending emails, messaging, updating systems, or triggering workflows, through authenticated, user-authorized integrations. By acting as an authenticated proxy based on the OpenAI API spec, Arcade.dev lets models invoke external services (such as Gmail, Slack, GitHub, Salesforce, Notion, and more) via pre-built connectors or custom tool SDKs, managing authentication, token handling, and security seamlessly. Developers work with a unified client interface (arcadepy for Python or arcadejs for JavaScript), facilitating tool execution and authorization without burdening application logic with credentials or API specifics. It supports secure deployments in the cloud, private VPCs, or on premises, and includes a control plane for managing tools, users, permissions, and observability.Starting Price: $50 per month -

Hush Security
Hush Security
Hush Security is a platform for discovering and governing AI agents and other non-human identities. It maps agent identities, credentials, permissions, tools, and infrastructure connections, helping security and identity teams assess risk and apply policy controls. The product is intended for organizations deploying AI agents and provides agent inventory, ownership attribution, activity auditing, access governance, and policy enforcement. Hush provides controls for limiting agent permissions and reducing reliance on static credentials, with visibility across agent and developer environments including Claude Code, Cursor, Codex, and Microsoft Foundry. Teams can use the platform to identify agents and credentials, review access, define scoped permissions, and monitor agent activity. Its free tier covers up to 25 protected agents, 50 access policies, and 10,000 discovered identities; paid plans support broader usage.Starting Price: $0 -

Keycard
Keycard
Keycard is an identity-and-access infrastructure platform built for the agent-native era, enabling developers and enterprises to securely connect AI agents, users, services, and APIs with real-time, policy-driven identity controls. It issues dynamic, ephemeral access tokens in place of static secrets and supports federated identity models to unify users, agents, and workloads under a distributed authorization framework. The platform provides drop-in SDKs for popular frameworks so developers can build agent-aware applications without becoming IAM experts. Keycard’s data model includes identity-attested agents, tasks, tools, and resources, allowing logical zones with context-aware permissions and auditability. On the policy side, security teams can define deterministic, task-based rules that enforce who (user/agent) can do what (task) on which resource under which conditions, all with full transparency. -
