Where they overlap

  • Software supply chain security is the primary category of both Archipelo and Socket.

Where they differ, field by field

  • Archipelo is also filed under AI model and agent security and Insider risk management. Socket is also filed under Software composition analysis.
  • Archipelo lists Salmon. Socket lists Socket Firewall, Socket for GitHub and Dependency Search.

How they differ

Archipelo sells Salmon, which it calls Execution Verification Infrastructure for establishing cryptographically verifiable execution history and state lineage. Archipelo says it builds Salmon for autonomous multi-actor software systems. CISO Tribune also files Archipelo under AI model and agent security and Insider risk management.

Socket sells Socket Firewall, which blocks malicious packages at install, and Socket for GitHub, which catches risky dependency additions and malicious updates in pull requests before they merge. Socket also sells Dependency Search, which shows security insights for open source packages across every major registry. CISO Tribune additionally files Socket under Software composition analysis. Socket states that its customers' source code never leaves their computer or CI environment, and that only the list of dependencies is sent to its service.

Archipelo says Salmon captures execution as it occurs upstream within supported environments, not downstream after the event has already taken place. Socket, by contrast, describes its platform as developer-first and says it scans every package and update for malicious behavior across all major registries. Socket says it serves industries including technology, media, healthcare and finance. On May 20, 2026, Socket announced a $60 million Series C funding round at a $1 billion valuation, led by Thrive Capital. Socket says it was founded in 2021. Archipelo, Inc. is the company developing and stewarding Salmon.

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: Socket

What Socket for GitHub does[1][3]
Socket for GitHub catches risky dependency additions and malicious updates in pull requests before they merge. A GitHub account is connected so that Socket can access and scan the repositories, and customers choose the repositories that Socket protects automatically. Socket can run on a CI/CD pipeline and creates a report for review. Socket creates a project health report for a project.
What Dependency Search does[1][3]
Dependency Search shows security insights for millions of open source packages across every major registry. Socket lets a user look up supply chain risks for a given version of a package in the ecosystem registry.

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]
