Build
Describe the system you need in plain words. Sentinel plans it, writes it, checks it and deploys it.
Application & AI control centre
Loglevel Sentinel gives you the tools to build, run and secure custom software.
It turns ideas into working business systems in minutes, built by your own people. It brings in the systems you already have — and keeps every one of them, and every AI request they make, under your control. On your own hardware, or in the cloud of your choice.
What is Sentinel?
Sales wants deal approvals. People wants onboarding. Operations wants shift planning. Hundreds of useful applications can quickly become a burden for IT. Sentinel is the control platform that makes them easy: it builds new systems, imports the ones you already have, runs each in its own container, and watches over all of them — including every question they send to AI.
Your systems
AI models
Describe the system you need in plain words. Sentinel plans it, writes it, checks it and deploys it.
See who is using what right now, how every system is doing, and what AI is being asked and what it costs.
A firewall that knows your systems, an AI gateway that scores every question, and lockdown when it matters.
01 Think It
A team needs a training dashboard, a compliance register or a smarter search. Write it the way you would explain it to a colleague. Sentinel turns the idea into a change package — a short, focused plan you can read before a single line is written.
02 Build It
In minutes, the Builder writes the code, runs the checks and deploys the result into the system's own container. Every change is saved as a snapshot you can roll back. Every file is readable in the codebase browser, and every database can be opened, explored and queried from one screen.
03 Protect It
Who is signed in, which systems are busy, how fast they answer, what AI was asked and what it cost — live. The firewall shows where traffic comes from and keeps out what shouldn't reach you. And if something ever goes wrong, one deliberate move locks every system down.
Build and change it yourself
A new system, a new field, a new report or a whole new module. The people who need it describe it in plain words, and Sentinel builds, checks and ships it while they wait. No development project, no waiting list, no consultants: your own team is in charge of its own systems.
Anyone who knows the work can ask for a change in plain words. No programming, no developers, no tickets.
A new field today, a new report tomorrow. Systems keep up with you instead of waiting for a supplier's next release.
An administrator approves with one click, and every change keeps a snapshot you can roll back in seconds.
The systems you build are yours, source code included. No per-seat or per-system licence fees for anything you create.
Your existing systems
A mid-sized company runs hundreds of smaller systems: a phone list, a booking tool, a supplier register that someone built years ago. Many are no longer maintained, and nobody watches them. Sentinel imports them, converts them to run in its own containers, bakes in AI where it helps, and from then on keeps them updated, monitored and secure, just like the systems it builds.
What you need: the original source code. Sentinel imports and converts each system from its source code, so you must have access to the original code for every system you bring in.

New life, new abilities
Once a system is in Sentinel, you can add AI exactly where it helps the people who use it: search that understands questions, drafts, summaries or checks, without rebuilding the system. Every AI feature runs through Sentinel's AI gateway, so it is logged, scored for risk and kept within your cost limits.
Bring in an existing system with its original source code and its data. Nothing has to be rebuilt from scratch.
Sentinel converts it to run in a standard Docker container, with backups and a snapshot of every version.
Live traffic, errors, users, AI use and firewall rules, on the same screens as every other system.
Updates, new features and AutoFix from the Builder. The original developer is no longer needed.
AI oversight
Every AI request from every attached system passes through Sentinel's gateway. It is logged in full, scored for risk before it is sent, and linked to the person, the page and the model — with its cost counted in real time.
Cost control
Sentinel prices every AI request the moment it is made, so you always know what AI costs you: today, per system, per person, per page and per model. Not as a surprise at the end of the month.
Illustration · names and values are examples
The prompt, the complete answer, tokens, cost and who asked. Search it, filter it, export it to Excel.
An automatic reviewer rates each question from safe to dangerous — prompt injection, secrets, personal data, off-topic use.
With the pre-send check on, requests that score 60 or more never reach a model. Your own review always has the last word.
See every page that uses AI, which user groups can open it and which models answer there.
Spend per system, per model, per page and per person as it happens, with a maximum cost per use wherever you want one.
Open-weight models run on your own hardware at no usage charge. Cloud models are used only when needed.
Bring your own AI
Developers keep the AI they already work with — Claude Code or Codex on their own computer — and connect it to Sentinel with one pasted text. AI agents that run inside your network can be locked into an NVIDIA OpenShell sandbox. Either way, every AI call passes through Sentinel, and Sentinel itself stays out of reach.

Claude Code or Codex talks to Sentinel over MCP, with a personal token. It sees what you see — and nothing more.
OpenShell is NVIDIA's open-source sandbox runtime for AI agents. Sentinel integrates it as an option: each sandbox runs in its own micro-VM, and a policy decides exactly which networks and files the agent can reach.
Live control
Sentinel's Live page follows every request through the gateway in real time: where it came from, which system it went to, how long it took, and how risky the AI part was. Dot speed follows response time — you can literally watch your systems breathe.

Why Sentinel
Every system runs in standard Docker containers, on your own servers or in AWS, Azure or any other hosted platform. Backed up, restorable and recoverable on its own.
You own every plugin you create, including its source code, and can reuse it across systems.
You own every system you develop. Nothing is locked inside someone else's platform.
No per-seat or per-system licences for the plugins and systems you create.
Every AI request from every system passes through Sentinel, is logged in full, risk-scored and reaches a model only when it is safe.
Sentinel knows who is asking, from which system and module — and with what data — so answers and access follow the person.
Describe a change. Sentinel's AI builds it in the right module, with cost, history and rollback on every step.
Accepted changes go live in the system's container automatically, with health checks and instant recovery.
Your company's values, context and rules shape how every request is judged — from safe to dangerous.
Editions
Both editions build, monitor and protect your systems, and in both every AI request goes through the same gateway: logged, scored for risk and kept within your cost limits. Enterprise adds scale, self-healing, compliance tools and high availability.

For a team or a department getting started with its own systems.
