List of the Top On-Prem AI Agent Authentication Platforms in 2026

Silverfort's Unified Identity Protection Platform pioneered the integration of security measures throughout corporate networks to mitigate identity-related threats. By effortlessly connecting with various existing Identity and Access Management (IAM) solutions such as Active Directory, RADIUS, Azure AD, Okta, Ping, and AWS IAM, Silverfort safeguards assets that were previously vulnerable. This encompasses not only legacy applications but also IT infrastructure, file systems, command-line tools, and machine-to-machine interactions. Our platform is designed to continuously oversee user and service account access across both cloud and on-premises settings. It evaluates risk dynamically and implements adaptive authentication measures to enhance security. With its comprehensive approach, Silverfort ensures a robust defense against evolving identity threats.

A production agent often needs the same access as the person who asked for the work. Scalekit supplies that access. It is the gateway those agents call, over MCP, when they have to act inside a customer's own software. The Free plan costs $0 and covers 10,000 tool calls plus 10,000 trigger events each month. Growth costs $99 a month for 100,000 tool calls, with extra calls at $0.50 per thousand. Enterprise is quoted. On that plan the Scalekit dashboard can use SSO and SCIM, and a HIPAA BAA is available. Hosted Scalekit runs in Los Angeles or in Frankfurt. Adding EU residency to Growth costs $99 a month. Larger deployments can sit in the customer's VPC, or on infrastructure the customer runs, with air-gapped installs supported. The trust center lists SOC 2 Type II and ISO 27001. Bartłomiej Krupa, a developer at Brand24, said: "We wanted our users to be able to ask their AI tools the same questions they'd ask Brand24 directly. Scalekit let us ship that without turning our engineering team into OAuth specialists." Under the hood, a request for Salesforce, Gmail, Slack, Notion, HubSpot, Jira, GitHub, or another of the 600+ connectors is matched to that person's stored login, allowed or refused, and sent. The catalog covers 35,000+ tools. Logins are encrypted with AES-256 and kept per tenant. The agent receives a result, not the secret. The same path works for code written with Anthropic, OpenAI, LangChain, Google ADK, Vercel AI, or Mastra.

Most companies write permission checks straight into each application, which makes access hard to change, hard to review and hard to prove to an auditor. Cerbos moves those rules into one authorization management platform that covers applications, API gateways, service meshes, data platforms and AI agents. Teams describe who can do what in short policy files that people outside engineering can read. Role, attribute and relationship rules (RBAC, ABAC, ReBAC and PBAC) live side by side. When a request comes in, Cerbos pulls the current roles and attributes from Okta, Microsoft Entra ID, your databases or internal APIs, then checks the request against the policy. A change to the rules ships after its tests pass, with no application release. What each team gets For engineering, one API call takes the place of permission logic spread across services, with SDKs in eight languages including Go, Java, Python and JavaScript. For identity teams, a single place to manage access for employees, customers, services and AI agents, next to the identity provider they already run. For product teams, custom roles and per-tenant permissions for enterprise customers without building them one customer at a time. For security teams, every AI agent tool call goes through the same policy check as a person, so agent rollouts can be approved with controls in place. Each check is recorded along with the policy that applied, which gives SOC 2, ISO 27001 and HIPAA audits a clear trail. Deploy it as a hosted service, in your own cloud or fully air-gapped. Customers running Cerbos in production include Utility Warehouse, 9fin and Salesroom.

Through its innovative approach, Keycard paves the way for a future where secure access is paramount for both human and AI interactions.

Idira is an innovative identity security platform developed by Palo Alto Networks, specifically designed for enterprises leveraging artificial intelligence, and it focuses on protecting various forms of identities—whether human, machine, or agentic—through a unified control system. This platform transforms the landscape of privileged access management by expanding the oversight of privileges to include all identities capable of engaging with sensitive systems, which involves a wide array of elements such as data, applications, cloud services, workloads, endpoints, secrets, certificates, SSH keys, and AI agents. By pinpointing potential identity risks, Idira dynamically modifies access privileges and oversees the entire lifecycle from the moment access is granted to the end of a session. Transitioning away from a conventional, always-available access model, it prioritizes dynamic privileges, just-in-time access, and zero standing privilege while ensuring ongoing verification and policy-driven controls with real-time enforcement that considers identity, device, and contextual factors. Furthermore, for human identities, Idira integrates privileged access management, workforce access, endpoint privilege management, and identity governance, equipping organizations with essential tools to effectively combat privilege sprawl. This holistic strategy not only fortifies security measures but also enhances operational efficiency across the entire organization, ultimately leading to a more secure and streamlined environment for all users.

Clutch is addressing the increasingly critical challenge of securing non-human identities within modern enterprises.
