This comparison is about identity and access controls for AI agents and other non-human identities (NHIs)—not model safety, prompt-injection defense, or runtime content inspection. Astrix and Aembit are the two reference points in the title; the five companies below are alternatives to investigate, not a ranked list or proven one-for-one replacements. A key availability caveat: Astrix says it is now part of Cisco and stopped standalone sales of new licenses on June 30, 2026. Astrix’s current notice says existing customers continue under their agreements while its capabilities are brought into Cisco over time. Confirm Cisco’s current packaging before treating Astrix as a new purchase option.
Which five alternatives are worth evaluating?
The five candidates below are Aembit, Oasis Security, Entro Security, Permiso Security, and Token Security. Aembit is included as a title anchor and current comparison point; the other four are candidates identified in Cloud Security Alliance (CSA) market materials. The CSA’s inclusion supports investigating them, but does not establish that their products have equivalent features or directly replace Astrix or Aembit.

| Company | Why it is on this shortlist | What is established here |
|---|---|---|
| Aembit | One of the title’s two reference platforms; it applies workload identity and access ideas to AI-agent access. | Its documentation describes short-lived credentials, access policies, credential isolation, centralized audit trails, and blended identity for user-driven agents. These are vendor-described capabilities, not independent performance findings. Aembit product information |
| Oasis Security | CSA identifies it as a company in the agentic-AI security landscape and as a purpose-built NHI vendor. | Relevant candidate for evaluation; agent-specific capabilities and feature parity are not established by the cited market references. CSA market materials |
| Entro Security | CSA identifies it as a company in the agentic-AI security landscape and as a purpose-built NHI vendor. | Relevant candidate for evaluation; agent-specific capabilities and feature parity are not established by the cited market references. CSA market materials |
| Permiso Security | CSA lists it among companies in the agentic-AI security landscape. | Relevant candidate for evaluation; detailed agent identity capabilities are not established by the cited market references. CSA market materials |
| Token Security | CSA lists it among companies in the agentic-AI security landscape. | Relevant candidate for evaluation; detailed agent identity capabilities are not established by the cited market references. CSA market materials |
These are candidates for a vendor shortlist, not a finding that all five currently sell the same type of agent identity product. Obtain current product documentation and confirm scope, availability, integrations, and packaging directly with each vendor.

What Aembit’s approach means for agent identity
Aembit describes AI agents as workloads and extends workload IAM concepts to their access. In its product documentation, the platform applies access policies, issues short-lived credentials, isolates backend credentials from agents, and centralizes audit trails. This is a vendor account of its capabilities; it is not an independently validated comparison against the other companies on the list.
#1 Best Overall
Blended identity for user-driven agents
For an agent acting on behalf of a person, Aembit documents “blended identity”: an access decision can take both the authenticated user and the agent workload identity into account. That distinction matters when an organization wants to avoid treating every agent action as either solely a person’s action or solely a shared service identity. Confirm how a vendor represents, enforces, and records both identities in the specific workflows you need.
How to compare the five candidates
CSA’s market map and research note establish a shortlist, not a feature-by-feature benchmark. Use the following questions to test whether a vendor actually covers your agents, credentials, and governance requirements. Request current documentation or a demonstration for the exact deployment and integration paths you intend to use.
Discovery and inventory
- Can the platform find agents built in-house as well as third-party or unmanaged (“shadow”) agents?
- Does discovery include MCP servers and the non-human identities or credentials those servers use?
- Can teams assign owners and track an agent’s lifecycle, rather than receiving only a point-in-time inventory?
Identity and credential handling
- Does each agent receive a distinct identity that can be tied to its owner and purpose?
- Can the product issue or broker short-lived credentials instead of leaving long-lived secrets with an agent?
- Are backend credentials kept away from the agent, and can access be revoked when an agent, workload, or integration is retired?
Authorization
- Can policy scope access by the user, agent, target resource, context, or requested action?
- For user-driven agents, can authorization consider both the user identity and the agent identity?
- Can teams limit access to the minimum required resources and actions, and inspect how policy decisions are enforced?
MCP and integration coverage
- Which MCP clients and servers are supported, and are the integrations generally available or limited to a preview?
- Which identity providers, cloud services, secrets vaults, and enterprise systems can the platform connect to?
- Does the vendor document the integration’s behavior, prerequisites, and limits for your specific environment?
Governance and audit
- Can the platform link an action to both the human user and the agent that performed it?
- Are policy decisions and credential use recorded in audit trails that can be exported to your existing security and compliance systems?
- Can administrators review ownership, rotate or revoke access, and investigate activity across an agent’s lifecycle?
Availability and commercial fit
- Confirm current product scope, licensing and packaging, deployment options, regional availability, support, and roadmap directly with the vendor.
- Ask whether an agent-specific capability is generally available, in preview, or planned; do not assume market-map inclusion means a feature is shipping.
- For Astrix, check Cisco’s current offering and sales path: Astrix’s standalone new-license sales ended June 30, 2026, while existing customers continue under their current agreements.
How to interpret the shortlist
CSA’s 2026 agentic-AI security market map includes Aembit, Astrix Security, Oasis Security, Entro Security, Permiso Security, and Token Security. Its separate discussion of the Astrix/Cisco consolidation identifies Oasis Security, Entro Security, and Aembit as purpose-built NHI vendors. Those references make Oasis, Entro, Permiso, and Token sensible names to investigate alongside Aembit, but do not show that they offer the same agent identity controls, integrations, or commercial availability. The cited materials do not resolve current pricing, deployment details, regional coverage, or comparative customer outcomes.
