For security teams
Control every action your coding agents take.
Coding agents run commands, read files, touch secrets and call the network with your developers' access. You can't trust agents to police themselves. Harden sits outside the agent, at its pre-execution hook, and checks every action before it runs.
What Harden checks
Every action, before it runs
Commands
Destructive commands, like dropping a database, rm -rf or a force-push to the default branch, are stopped before they execute.
Files and pushes
File edits and git pushes are checked against what the session was asked to do. The same command, two intents, two different decisions.
Secrets
Harden follows data from where it came from to where it's going. If a secret is headed for a network call, a log or the agent's output, Harden blocks or redacts it.
Network calls
Commands that reach the network, like a script piped from curl into a shell or a request carrying a secret, are checked before they run.
Deterministic
The same action gets the same decision
Harden's enforcement path is deterministic. It parses each command, follows the data and applies your policy, so the decision you can explain today is the decision you get tomorrow.
Obfuscation doesn't change the answer. Base64, hex and similar encodings are decoded before analysis. Genuinely dynamic code, like eval, goes to a person with the evidence recorded. Harden never guesses.
Audit
Records for every decision
Every decision is recorded with the action, the verdict and the reason, and can be exported to your SIEM. Audit and incident response start from evidence, not from a chat transcript.
Deployment
Runs on your developers' machines, not ours
- Decisions are made 100% locally, in milliseconds. Nothing leaves the machine.
- Pushed by the MDM you already run
- Starts watch-only, so you can tune policy before you enforce
- One policy across Claude Code, Codex, Cursor, Antigravity CLI and Kiro
SOC 2 Type 2
FAQ
Questions we hear
Does any code or data leave the developer's machine?
No. Harden decides on the developer's machine, in milliseconds. Nothing leaves the machine unless you choose to export decision records to your SIEM.
How is this different from the agent's own permission settings?
Permission settings are allow-lists the agent applies to itself. Harden sits outside the agent, so the agent can't approve its own actions, and it checks each action against the session's intent, not just its name.
Is Harden SOC 2 compliant?
Yes. Harden is SOC 2 Type 2. The Trust and Security page covers data handling, encryption and sub-processors.
How do we deploy it across our fleet?
Push it with the MDM you already run. It starts watch-only, recording what it would have decided, so you can review and tune policy before you turn on enforcement.
What doesn't Harden do?
It doesn't replace least privilege, scoped credentials or network egress policy, and it doesn't contain a process that is already malicious. Its job is to decide what coding agents may do, before they do it.
