Discover, secure, govern, and optimize AI where the work happens.
Halo finds the AI your people and agents use, applies policy in browsers, on laptops, at model and tool gateways, inside agent runtimes, and records each decision so reviewers can see what happened and why.

One control plane
See it, secure it, prove it, and spend with intent
Halo brings discovery, runtime security, governance, and cost control into one continuous system.
Expose shadow AI
Find AI sites, extensions, apps, developer tools, and local runtimes on the browsers and devices you enroll, including the ones nobody approved.
Enforce at the moment of action
Policy decides before a supported tool call runs or a governed action goes through.
Hand reviewers real evidence
Decisions, approvals, and changes are recorded with reasons and export as CSV or JSON.
Spend with intent
Budgets act at thresholds you set, and cost shows up by agent and by model.
The product
A control plane your operators will actually use
Fleet health, quick deploy, budgets, and security decisions, all in the current Halo interface.


Coverage
Govern the AI you build, buy, and find
Whether an agent was purpose-built, arrived inside a tool your team adopted, or was never approved at all, Halo brings discovery, policy, and evidence to the supported surfaces where it runs.
Agents you build
Launch agents with security built in
Set the job, model, app access, approvals, and budget together, then run in a sandboxed runtime with brokered credentials.

Bring shadow AI into the inventory
Halo Browser and Halo Endpoint surface AI in use on supported surfaces and classify it, so security can decide with facts.

Govern each model request and tool call
Route model and MCP traffic through gateways that apply identity, policy, approvals, and budgets, and record the outcome.

Why Halo
Built for how AI actually shows up at work
Halo connects visibility, enforcement, and evidence, so the rules you write are the rules that run across the supported browsers, endpoints, gateways, and agent runtimes your teams use.
Enforcement where AI actually runs
Browsers, devices, gateways, and agent runtimes each get controls suited to them, under one policy model and one evidence record.
Security and efficiency in one decision
The same request is checked for policy, budget, and model fit, so safer AI is also the more economical path.

Build AI budgets that follow the owner
AI budgets work when each agent has an owner, thresholds trigger clear actions, and exceptions leave a record. See how account and per-agent budgets fit together.

Frequently asked questions
Halo Browser for Chrome and Edge, plus Safari on macOS and Halo Endpoint for macOS and Windows identify AI websites, extensions, desktop apps, developer tools, local runtimes, and add-ins on enrolled devices, then organize them into an inventory with source and confidence.
Agents that run on Halo get a sandboxed runtime, brokered credentials, policy, approvals, and budgets. Model and tool traffic that flows through Halo gateways receives the same identity, policy, and evidence controls.
Policy evaluates the request at runtime. Halo can allow it, deny it, raise an alert, or pause it for a person to approve, and it records the decision with the reason so reviewers can see what happened.
Gateways move traffic and dashboards report after the fact. Halo combines discovery on browsers and devices, gateways for model and tool traffic, a secure agent runtime, policy, budgets, and evidence in one control plane.
Account and per-agent budgets notify, pause new operations, or stop active deployments at thresholds you choose. Cost analytics show spend by agent and model, and model routing profiles help match each workload to an approved model that fits its cost and quality needs.
You can sign up and launch a first secure agent through the self-serve quick deploy path. Browser and endpoint discovery rolls out with guided onboarding, usually starting in observe mode before teams turn on warnings or enforcement.
Put a halo around the AI your business runs.
