Try it — free7-day log retention

Secure environments for an insecure world.

Punitive security doesn't work — your people shouldn't have to be security experts. Developers want to build; everyone else wants to browse. Bromure gives each a sealed environment: productive for them, safe for the company.

The principle

Don't restrict the person. Seal the environment.

Lock people down and they route around you — and you lose both the control you reached for and the visibility you had. Bromure takes the opposite bet: let people work the way they want, inside an environment that can't hurt the company. One model, two surfaces — the developer's agent and everyone's browser.

For developers · Bromure Agentic Coding

Hand over the whole machine. Keep the blast radius in a box.

Coding agents are only useful with real access — your repos, your cloud, your registries. Bromure leaves that power intact and leashes what a mistake, a poisoned dependency, or an agent off the rails can actually reach.

Secrets never enter the sandbox

Real tokens and SSH keys stay on the host. The agent gets stubs; a proxy swaps in the real bearer at the wire. A scraped filesystem walks away with placeholders.

Guardrails on every key

Bromure reads the operation, not just the connection. A DELETE, a force-push, a DROP against production stops and asks first — whatever token it's holding.

Supply chain scanned at the boundary

Every package the agent pulls is checked against OSV and socket.dev, install scripts are stripped, and brand-new releases are held back — before any of it reaches the VM.

Prompt injection caught before the model acts

Bromure scans what the agent reads — file contents, web pages, tool output — for injected instructions, and CLAUDE.md-style rules files for hidden orders. On-device, before the request ever reaches the model.

How the secrets stay out

The agent gets a stub that looks real to git, gh, kubectl, aws, npm — anything expecting an Authorization header. A proxy on the host swaps in the real bearer at the wire.

The real token never touches a file, env var, or page of memory the VM can reach. A poisoned dependency walks away with the stub.

Fleet visibility

Everything the agent did, on the record.

Every session streams to your admin console — across every developer and every machine. Three answers IT could never get before:

An inventory of every package downloaded

Each dependency any agent fetched — ecosystem, name, version, and the verdict that let it in or kept it out. Search the whole fleet for a compromised release the moment it hits the news.

Which files, in which repo, cost how many tokens

Token spend rolled up by repository and by file. See where the agent burns budget, which codebases are expensive to work in, and who is driving the bill.

A full trace of what the agent did

Every prompt, tool call, shell command, file write, credential use, and flagged prompt-injection attempt — captured live, replayable, and attributable. "It just broke" becomes a record you can hand an auditor.

Across the whole fleet, every dependency, dollar of token spend, and action the agent took is one query away — without ever slowing a developer down.

For everyone else · Bromure for the browser

A controlled browser in an uncontrolled world.

Every web session runs in a VM you manage — on any laptop, corporate-issued or personal. Managed profiles, SSO-gated access, full audit trails, and nothing leaves.

Built for BYOD.

Every session runs in its own virtual machine — a controlled environment inside an uncontrolled one. Personal MacBook, contractor's laptop, corporate device: it doesn't matter. The work browser sits in a VM you manage, and the host can't reach it.

Network-isolated, so a compromise on the personal OS can't pivot in. Filesystem-sandboxed, so nothing leaks to Downloads. Integrity-checked, so the image is bit-for-bit the one IT shipped.

Access is tied to your IdP — Google Workspace, Okta, Microsoft Entra, Authentik. No valid session there, no corporate browser.

Offboard a user in your directory and their Bromure install is revoked the same way their email is. One source of truth, one switch to flip.

EDR meets web browsing.

Every HTTP request is logged. "Who sent credentials to evil.com between 8:00 and 8:15 yesterday?" — answered in seconds, across the whole org.

Your corporate data stays in the company.

Forbid copy-paste, file downloads, and screenshots. Your data lives inside your SaaS apps and nowhere else — no USB sticks, no personal cloud, no way out of the VM.

Bring your own SIEM

Everything Bromure sees, in your SIEM.

Both surfaces emit one security event stream — every agent action, every browser request, every admin change. Point Bromure at your SIEM or OpenTelemetry Collector and it forwards all of it as OTLP/HTTP logs, mapped to OTel semantic attributes, on a durable cursor that loses nothing if your endpoint blips.
