An afternoon shortlist from the agent identity index

A bounded deliverable for the session

The existing ranking articles explain why different weights can produce different leaders and why ties need care. This guide takes a narrower task: producing a usable evaluation brief before the session ends. The brief should name the workflow, the capability that must work and the missing evidence that could rule a product out. A shortlist without those fields can become a list of familiar names rather than a plan for a decision.

The session should end with a small set of candidates and a reason to test each one. It does not need to settle a full architecture or declare a winner. The practical boundary is whether the team can send each candidate the same concrete workflow and understand what evidence would count as success. The index helps organise that work, but its documented claims are not deployed performance measurements.

The failure boundary as a starting point

The first note should describe the agent, its accountable owner, the resource it needs and the action that creates concern. A buyer worried about unknown agents has a different starting point from one that already knows its agents but needs to prevent a sensitive tool call. A buyer removing standing secrets has another. These distinctions correspond to the index's discovery, runtime and credential-oriented buyer situations.

The team can write a plain-language acceptance condition before reading ranks. A discovery condition might require finding an agent not registered in advance and attaching evidence of ownership. A runtime condition might require stopping an action before execution. A credential condition might require scoped, short-lived access without exposing a downstream secret to the agent. These are proposed test conditions, not assertions that any candidate has passed them. The next step is to match them to the documented capability evidence.

The matching situation without score changes

The published buyer situations weight the same capability set differently. The discovery situation emphasises finding agents and accountable ownership, while the runtime situation emphasises per-action policy and human approval. The credential situation prioritises credential lifetime and delegated access. A shortlist should record which situation was used and why its emphasis matches the workflow. The score is then a navigation aid, not an unexplained decision rule.

The team should not change criterion scores during this exercise merely because a new announcement sounds relevant. It should inspect the underlying evidence and retain any unresolved gap in the trial brief. The method also needs to preserve exact ties rather than interpret display order as a substantive advantage. A candidate with a relevant documented strength may deserve a test even if its overall position is lower in a situation aimed at a different problem.

Read strengths and limits in the same pass

The discovery-oriented evidence for Silverfort describes agents, underlying machine identities and accountable human owners. The Astrix record describes inventory of agents, servers, secrets, permissions and owners, while noting that provisioning policy is not verified per-action interception. Those facts can support a discovery shortlist while discouraging an unsupported leap to runtime coverage. The buyer should carry both the useful context and the limitation into the evaluation brief.

The Aembit evidence describes per-request credential exchange and blended human-agent context for delegated access. Keycard describes just-in-time scoped credentials and step-up human approval, while broad discovery of unknown agents is not documented. Those are different reasons for inclusion. A team looking for a controlled tool-access path can test them without pretending that either record establishes an estate-wide discovery programme. The shortlist should make the reason for each candidate explicit. [aembit-c4-1] [aembit-c5-1] [keycard-c4-1] [keycard-c7-1] [keycard-c2-1]

The existing identity provider in the architecture

The identity-provider context page should be checked before deciding what additional layer is needed. The Okta October source confirms registration and import additions, while the Microsoft October source describes expanded agent patterns and shared context. Neither source should be stretched into a statement that every approval path or tool boundary is covered. The team should identify the remaining workflow gap after recording the relevant provider capability. [f3] [f7]

The NewCore record is relevant where the workflow needs agent governance alongside the existing IdP. It documents per-action policy and human approval; the sourced announcement claims discovery of unregistered agents and task-scoped credentials. The record also says direct command-line tool calls bypass the MCP gateway today and that no list price is published. A shortlist entry should preserve those limits and request a quote, rather than assume either complete runtime coverage or a public price. [newcore-c3-1] [newcore-c7-1] [n2] [newcore-c8-1]

The common trial brief

The trial brief should give every candidate the same starting state and requested action. It should distinguish a record appearing in inventory from an action being prevented, and a policy approval from a human decision. A buyer can request a trace showing the owner, agent, resource, decision and resulting credential or denial. That request defines the evidence to collect; it does not claim that every product exposes the same trace or export.

The final pass should remove assumptions about availability, pricing and corporate transactions from the capability column. The planned gateway availability remains planned until an Okta source confirms otherwise. The reported acquisition talks remain talks. An unavailable price remains a commercial question. The team can then leave the session with a reasoned shortlist, a common test and explicit questions instead of a ranking copied into a purchasing decision. [f2] [f9]

• The workflow field names the agent, owner, resource and sensitive action.
• The inclusion field links the required capability to an existing source.
• The gap field records unsupported coverage, availability and plan questions.
• The trial field defines the starting state, expected decision and evidence to retain.
