Secure the agents and CLIs writing your code.
Coding agents and CLI tools read your repo, your secrets, and your env files, then send context to models you do not control. Cerbera adds inline guardrails across every IDE agent, terminal CLI, and API call your team runs.
[Problem]
Your coding agent has the keys to the repo.
Agents and CLIs are fast because they have broad access. That same access is what makes them dangerous when no one is watching what leaves.
01
Secrets ride along with context.
Agents send source code, API keys, and environment variables to external models as part of normal completions.
02
Agents reach further than you think.
An agent with repo access can read production config, SSH keys, and internal tools, often beyond what any single task needs.
03
Every developer runs a different one.
Cursor here, Claude Code in the terminal, Codex CLI there. Each is a separate surface with separate risk and no shared control.
[How it works]
Guardrails the agent never feels.
Cerbera sits inline as a transparent proxy across every agent and CLI, so the same policies apply whether code is leaving an IDE, a terminal, or an API call.
Inline guardrails
Block secret exposure and detect source code leaving through an agent, before the request reaches the model. Redact rather than block, so completions keep working.
Context visibility
See exactly what code context each agent and CLI sends, to which model, so you can answer what left and prove what did not.
One layer across every surface
IDE, CLI, and API are covered by the same proxy and the same policies. New agents and clients are detected and held until you approve.
Limit what agents can touch
Draw hard lines around what an agent can reach. No SSH keys, no production, no tools you never sanctioned.
[Clients]
Every agent and CLI, one policy.
Cursor, GitHub Copilot, Windsurf, Claude Code, and whatever ships next. Cerbera is client agnostic, so a new agent or CLI inherits your existing guardrails the moment it shows up.

Works everywhere. Leaks nothing.
Transparent AI proxy
All agent and CLI traffic flows through Cerbera's transparent proxy with negligible latency. Developers never notice it is there.
- >Around 100ms at P99, invisible against multi-second completions
- >Real-time inspection of prompts, responses, and tool calls
- >Works across IDE, CLI, and API traffic
- >Coexists with your VPN and DNS proxy
Manage via MCP, stream to your SIEM
Configure Cerbera from the AI tools your team already lives in, and send AI signals to your existing stack.
- >Review policies and inventory over the Model Context Protocol
- >Built on OpenTelemetry for Splunk, Datadog, and Sentinel
- >Fleet-wide deployment via any MDM
- >One-click install and removal
Privacy by design
Detection runs locally on the device. Nothing leaves your network by default, and logging is opt-in.

[FAQ]
Frequently asked questions
Cursor, GitHub Copilot, Windsurf, Claude Code, and terminal CLIs today, plus new ones as they emerge. Because Cerbera is client agnostic, a new agent is covered by your existing policies the moment it connects.
No. Redaction happens in under 5ms on the device, and the proxy adds around 100ms at P99, invisible against the multi-second responses agents already take.
It targets leaks, not productivity. Cerbera redacts or blocks secrets and sensitive context on the way out, while the agent still receives a usable prompt and returns its suggestion.
Fleet-wide through any MDM, with one-click install and removal. There are no per-developer setup steps, and you can manage policies over MCP from the tools your team already uses.
