Fullstack Nexus
AI control and governance platform
Your AI is already in production. Now put it under control.
Fullstack Nexus is one point between your applications and agents, the AI providers and the tools they use: it controls what happens, measures what it costs and leaves signed, verifiable proof of what occurred. In your cloud, with your data inside your network.
Three questions your company should be able to answer
Finance: “How much did we spend on AI last month, and which client or which process generated it?”
Security: “What is the AI allowed to do today, who authorized it, and what has changed since?”
The auditor: “Show me what the AI did on this request, and prove to me the record was not altered afterwards.”
All three share the same cause: there is no central point. Nexus is that point.
One platform, two pieces
Connecting and governing are one thing: one makes no sense without the other. On that base, everything else is built.
The control point
One point between your applications, agents and coding assistants and the AI providers and tools you choose.
Connect gives you one address for every provider, with automatic fallback and one model name that picks by rules who serves each call, plus connectors to the official MCP servers of GitHub, Jira and Confluence, Slack and Google Workspace (in beta). Govern applies your rules on every one of those calls: guardrails for personal data and attacks, budgets and limits per client, team and person, human approval for sensitive agent actions, and a signed, time-stamped record.
Business value:
No provider lock-in, costs under control, risks stopped before they happen, and evidence your auditor verifies outside Nexus.
Nexus Connect + Govern
What you build on top
Agents, workflows and copilots on the same control layer.
Nexus Extend adds new capabilities that inherit everything Connect + Govern already does: the same rules, limits, approvals, cost tracking and signed record. Nothing to rebuild for each new initiative.
Business value:
Each new AI capability reaches production faster, already governed.
Nexus Extend
What Nexus is
It sits between your applications and agents and the AI providers and tools you choose. Every call goes through it.
What Nexus solves in your company
Five situations companies with AI in production already face.
Knowing what each thing costs, and stopping in time
Every client, team and person has their spend in view and their limit. Nexus warns before the cap and blocks once it is exceeded.
Stopping attacks and data leaks before they happen
Every input and output is reviewed. Personal data, including each country’s ID documents, is masked or blocked before it leaves. Any rule you are missing, you define in plain language, with no code.
Letting agents act on your systems safely
Your agents use GitHub, Jira, Slack, Google Workspace (in beta) or your own MCP servers through Nexus, with rules on every action. Sensitive actions wait for a person’s approval.
Ending orphaned access
Every integration has its own credential with its own limits; it rotates without downtime and expires when you say.
No provider lock-in, and the right model
One connection for every provider, with fallback if one fails. One model name can pick, by rules, who serves each call, and the savings are measured.
What makes Nexus different
Five things you will not find in a plain AI gateway.
The proof does not depend on us
Every record is signed, chained and time-stamped; your auditor verifies it outside Nexus. If someone switches signing off, the gap stays visible, with who did it and why.
You know which step drives the spend
Real cost per unit of work: a ticket, a document. Rework is counted separately, so you know whether changing the model would help.
Each record is kept for as long as you decide
Each type with its own period, and every deletion by retention leaves a signed record. Auditors can only read.
The rules always apply
No application can bypass them, not even through a cached answer. If they cannot be applied, the call is rejected.
Each role sees what it should
People who use the AI do not see the configuration or the credentials; administrators govern it; the auditor reads everything and changes nothing.
Your AI’s whole path, on one map
AI Maps (beta): what happens to each call is configured in several places; AI Maps draws it all together, and every problem says what is wrong and how to fix it.
Every model’s route, step by step
Who can call it, guardrails, cache, router rules, main model and fallbacks, each step with its live status. One click opens the screen where it is configured. A dry run shows which rule would win, without calling the provider or charging anything.
How your agents reach their tools
Who may use each MCP server, its tools, the rules on each one and who approves. Whatever needs attention is flagged, with how to fix it.
What an agent did, in order
Every call to the model and to tools, with cost, time and decisions: here, a write to GitHub that ran after a person approved it.
Who it is for
It works the same for the AI you use and the AI you sell: each team or client with its own spend, rules and evidence.
Software companies with AI in their clients’ hands
You know which client generated each cost and have their consumption ready to bill. Automatic billing comes switched off; you turn it on when you need it.
Companies selling AI to regulated sectors
Cost and signed evidence per client, without building it yourself.
Banks, insurers and regulated entities
Your auditor sees which model was used, with which data, and who approved it.
Consultancies implementing AI for several clients
You govern the AI you implement and measure what each client consumes, with your margin.
Compliance
ISO/IEC 42001 · ISO/IEC 27001 · SOC 2 · GDPR
Nexus supports your controls and generates the evidence the standards require. ISO/IEC 42001, ISO/IEC 27001, SOC 2 and GDPR do not certify products: they assess how your company governs AI, and Nexus is one piece of that system. Every call, every agent action, every approval, every access and every configuration change is recorded, signed and time-stamped, and your auditor checks it with a verifier that runs outside Nexus.
You define which regulation applies, which controls you must show and how long to keep each record. Nexus gives you the evidence, an installation in your own infrastructure and jurisdiction, and a read-only auditor role.
How to adopt it
Without rewriting what you have and without taking data out of your network.
Step 1. It installs in your cloud
In your infrastructure and the jurisdiction you choose, with your own provider keys.
Step 2. Your applications point to Nexus
They change the address they call and keep working the same. Your agents and coding assistants come in through the same point.
Step 3. You govern it from a console
Models, rules, spend limits and connectors, all through configuration and also through the API. Nexa, the console’s assistant, explains every screen.
FAQs
Common Questions About Fullstack Nexus
What companies ask before putting Nexus in front of their AI.
Where do my data and prompts stay?
In your infrastructure. Only what each call sends to the model goes to the AI provider you chose, and every transfer is recorded. If you turn on risk review with an external model, that text goes to the provider you configure with your own key; you can operate without it.
What if an AI provider fails or raises its price?
You switch provider or model from the configuration, with automatic fallback, without touching your application. With a model name that picks by rules, you change the rule and the application never notices.
What if an agent spends ten times more because of a bug?
Limits per credential, team or client, and person warn before the cap is reached and block once it is exceeded.
Can I resell AI to my clients and bill it per client?
Yes. Each client has its own cost, limits and evidence, and you export each client’s consumption to bill it; you set the price. Automatic billing comes switched off.
Does Nexus help with a SOC 2 or ISO audit?
Yes. It generates the technical evidence those audits ask for about AI use, all recorded and signed, and your auditor checks every record with a verifier that runs outside Nexus.
What happens after you write to us?
A conversation to understand how you use AI today. If it makes sense, a pilot in your cloud with a written success criterion. Then you decide.
