Who it fits	From its own pages, Archipelo's Salmon addresses software in which autonomous agents, tools, runtimes, and controllers perform consequential actions. Archipelo describes incident investigation teams as needing to work backward from a consequential state change toward the execution associated with it. Archipelo names systems that investigate, evaluate, govern, and depend upon execution as the systems for which verifiable execution history matters.	From its own pages, the company sells mainly to organisations with cloud environments, saying its autonomous agents investigate your cloud and map what actually needs fixing. It also lists delivery partnerships for MSPs, MSSPs, and consultancies, so service providers are a stated audience. It publishes cloud security reference articles on controls and frameworks as well.

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 Plerion

Plerion calls Pleri its primary AI security agent.^[2]

Plerion addresses a backlog that no security team works through manually once ten developers use AI coding assistants. Plerion describes a finding that spans a service, a team, and a vendor, and that nobody picks up because nobody is sure whose job it is. Plerion states that 46% of code shipped today is AI-generated, while the list of issues that took a week to triage is still taking a week.^[2]

Plerion shows what agents can access and what they can do. Plerion traces each agent to the code, identities, infrastructure, and data it touches, so that teams can fix the risks that matter.^[2]

Plerion's agent investigates findings, decides whether they need dealing with, and submits a fix. The engineer who owns the resource reviews and approves the change.^[2][3]

Pleri orchestrates a set of specialist skills, each covering a different part of the cloud estate.^[2]

Plerion publishes an article based on the AIS-05 control from the CSA Cloud Controls Matrix v4.0.10, dated 2023-09-26. Plerion's article on automated application security testing covers considerations, strategies, and practices for implementing that testing based on guidance in the Cloud Controls Matrix of the Cloud Security Alliance.^[2][4][6]

Plerion's data security guidance notes that the DSP-01 control maps to several other industry standards and regulations related to data privacy and security.^{[1][2][3][4][5][7][8][9][10][11][12][13][14]}
