What it sells: Archipelo

What Salmon does^{[1][2][3][4][5]}: Salmon is Execution Verification Infrastructure for establishing cryptographically verifiable execution history and state lineage. Execution is represented as a cryptographically signed event with explicit context. Salmon captures execution as it occurs upstream within supported environments.

What it sells: Knostic

What Kirin does^{[4][5][6][7][11]}: Kirin runs on the endpoint inside supported agents and sees the tools, extensions, servers, and skills actually installed and used. Kirin denies a destructive command before it executes, tells the developer why, and logs a Prevented alert for the SOC. Kirin blocks the connection to an MCP server before it is established, after AgentMesh scans and rates the server. Kirin deploys as an extension for Cursor and VS Code.
What AgentMesh does^{[4][5][6][7][11]}: AgentMesh rates every skill, server, and extension. AgentMesh scans MCP servers for prompt injection, malicious behaviour, and supply-chain risk. AgentMesh detects prompt injection in skills, MCP servers, and extensions before install. Every paid AgentMesh plan includes Kirin IDE security.

About Archipelo

Archipelo develops Salmon, Execution Verification Infrastructure for establishing cryptographically verifiable execution history and state lineage. Archipelo builds Salmon for autonomous multi-actor software systems. Archipelo, Inc. is the company developing and stewarding Salmon.^[1][3][4][5]

Archipelo states that autonomous agents, tools, runtimes, and controllers increasingly perform consequential actions themselves. Archipelo states that the resulting state alone cannot show which execution occurred, in what order, or how each state transition derived from the ones before it. Archipelo develops infrastructure that makes autonomous multi-actor software execution independently verifiable. Archipelo states that safe and reliable agents need verifiable evidence of their execution history.^[4][5]

Archipelo points to Git as showing the value of persistent, linked source code history. Archipelo says Execution Verification Infrastructure addresses a different problem, which is establishing a verifiable record of state transitions and the resulting state.

Archipelo describes execution as represented by a cryptographically signed event with explicit context. Archipelo states that Salmon captures execution as it occurs upstream within supported environments, not downstream after the event has already taken place. Archipelo states that Salmon does not visually or structurally manufacture execution continuity when execution continuity has not been established.

Archipelo states that agent generated changes can involve delegated execution, tools, subprocesses and multiple state transitions. Archipelo states that execution history provides a durable record of supported execution relationships to verify outcomes. Archipelo states that during incident investigation, teams need to work backward from a consequential state change toward the execution associated with it, to determine what caused the outcome.

One principle is that downstream systems should not be forced to establish execution history solely through retrospective inference where it can be captured during supported execution. Archipelo states that what an actor was permitted or instructed to do is distinct from what it actually executed. Archipelo states that machine-speed software systems require execution evidence that other software systems can consume and verify. Archipelo describes identity, policy, observability, security, engineering, and governance systems as solving adjacent problems.^[5]

Archipelo describes itself as a deep tech company building foundational infrastructure for verifiable autonomous systems.^[1][3][4][5]

About Knostic

Knostic discovers and secures agents, coding assistants, and their supply chain, from MCP to skills and Code to Cowork. Knostic enforces rules by checking every action against policy before it runs, so allowed actions proceed and risky ones are blocked or sent to a human. Knostic applies least privilege to what agents do, watches every action as it happens, and blocks the unsafe ones before they execute.^[1][6]

Kirin is the Knostic product that runs on the endpoint inside supported agents. Kirin sees the tools, extensions, servers, and skills actually installed and used. In one example, Kirin denies a destructive command before it executes, tells the developer why, and logs a Prevented alert for the SOC. AgentMesh rates every skill, server, and extension. Every paid AgentMesh plan includes Kirin IDE security.^[4][6][11]

Knostic discovers every agent, model, and AI tool running across endpoints, attributes each to people and teams, and brings them under one policy. Knostic finds agents, extensions, MCP servers, and skills where they run, on the endpoint, rather than inferring from network logs. Discovery is passive, and policy can run in Monitor mode before anything is enforced. Discovered components are rated using AgentMesh verdicts and policy posture. Knostic maps which teams and individuals use which tools and what they can reach.^[4][6]

Knostic describes one control plane for all agents, models, and AI tools. Knostic unifies and centrally governs agentic security policies and configurations. Teams can scope what agents may read, write, run, connect to, and install, per team. Knostic describes its guardrails for SaaS, in-house, coding, and Cowork agents.^[1][6]

For prompt injection, Kirin catches the injection and blocks the action it would have caused. Kirin inspects what an agent is about to do, not just what it was told. Knostic scans prompts, retrieved context, and tool responses for injection and malicious instructions. Knostic catches credentials in prompts and outputs and blocks or redacts them, in Monitor or Enforce. Teams choose block, downgrade, route to a human, or log per rule and per team. For code, Knostic states that agents model threats before they code, follow secure coding rules, and have every package checked.^[1][11]

Knostic keeps an up-to-date list of allowed MCP servers, with every connection validated in real time. Knostic flags deviations from policy or misconfigurations as they occur. AgentMesh continuously rescans the ecosystem, and Knostic research feeds new detections. Decision logs and runtime monitoring provide evidence for audits, incident response, and policy enforcement.^[6]

Kirin supports Claude Code CLI, Claude Desktop and Cowork, Cursor, Windsurf, and VS Code + GitHub Copilot, on macOS and Windows, and Linux is in beta. Managers provision the console, push the endpoint client to the endpoints, directly or via an existing MDM, and start in Monitor mode. For Cursor and VS Code, Kirin deploys as an extension and requires the client for shadow AI visibility.

Kirin has three tiers, from individual developers to enterprise-wide rollouts. Knostic provides a package with SOC 2, pen test reports, and a data flow diagram in its trust center. Knostic Inc. is a company incorporated under the laws of the State of Delaware.^[4][8][9]
