Plexus™ by Subnet345
Plexus™Software for coordinating autonomous AI agents. Installed in your environment, not hosted in ours.
Plexus is software you run yourself. You purchase it, and our engineers install and set it up in your cloud tenant or on your on-prem servers. From there your team operates it, inside your own boundary, on infrastructure you control. We deliver the software and stand it up; we never host it, and your data never leaves your environment.
One record, every seat that answers for your agents
Plexus produces one record of what your agents did. Each part of your organization reads it for what they answer for.
GRC & Compliance
The record your framework assumed you kept.
When an examiner asks what an agent did, you produce the substrate, not a scramble. Recorded actions are attributed to a specific agent and tamper-evident, retained where you can hand them over. Policy-violation events carry the exact rule and version that fired. It is the kind of complete, time-stamped audit trail SEC Rule 17a-4 recognizes, and the governance SR 26-2 leaves to each institution for agentic AI. Plexus produces the evidence these frameworks expect. It does not make you compliant on its own.
Audit & Assurance
Your auditor walks the chain in your environment.
No vendor log-export your auditor cannot independently verify. The record is hash-chained and anchored to an external reference, and your auditor independently re-verifies it against that reference over the recent window, in your own perimeter. The system that verifies the record is separate from the one that wrote it, so the question of who wrote the log you are auditing has a clean answer.
Security · CISO & SecOps
Post-incident review from your own record.
When the review asks what an agent did at 2:47am, you reconstruct it from the substrate, not from weeks of vendor-log triangulation. Recorded actions are attributed to a specific agent across the runtimes you run. Refusals are recorded as first-class evidence, the signal your SecOps team wants. The record is produced as the action happens, inside your perimeter.
IT & Engineering
Software you run. Not a SaaS bill that grows.
Plexus installs in your cloud tenant or on your on-prem servers and integrates with the agent runtimes you already use, such as Claude Code and Codex. Your team operates it. The governance substrate has no outbound dependency. It does not phone home, so it adds no data-egress vendor to your third-party risk scope. Your AI runtimes still call their own model APIs. That is their business, not the substrate's.
Finance · CFO & FinOps
Know what your AI operation costs, on infrastructure you own.
See your AI spend attributed to the agents that produced it, for the runtimes that emit cost telemetry, currently the Claude Code, Codex, Gemini, and Antigravity classes we support. It runs on infrastructure you own: no per-seat SaaS bill that grows with headcount, no data leaving your environment. A governance-cost line you control, and the record to defend what the spend produced.
Plexus is licensed software, not a hosted service. Purchase includes professional-services install and setup: our engineers deploy Plexus in your cloud tenant or on your on-prem servers, integrate it with the AI agent runtimes you already run, and hand it to your team to operate.
Subnet345 provides Plexus installation, integration, and setup services. You own the environment it runs in, and your auditor can walk the record where it lives.
