Security Policy

Last updated 2026-10-04

dejav runs an automated browser against your site. This page describes how the agent is isolated, which sites and pages it may test, and how your data is stored and deleted.

A padlock clicks shut and a check confirms it is locked.

Isolated runs

Each run is designed to execute in a sandboxed browser. Its network rules are designed to let it reach only the site under test and the services dejav itself runs on, such as its AI, storage, and GitHub providers and its own internal network, and to block the rest of the internet. The run's browser session, working files, and network permissions are designed to be discarded when the run ends. These measures can fail or behave unexpectedly.

A sandboxed run is designed to reach only the site under test and the services dejav itself runs on. Other sites, other customers' runs and the rest of the internet are restricted by design.

Domain verification and excluded paths

dejav sends edge-case and invalid input, so it should test only sites you control. Add a DNS record to verify your domain; until then, each scan or run covers up to 30 test cases. Paths you exclude, such as admin pages or a live checkout, are intended to be blocked in the browser, including redirects and new windows that lead there. A test that needs one is normally reported as incomplete, not as a failure of your site. Connections a page opens from inside a web worker are not covered, and no restriction is a guarantee that a path or another service cannot be reached.

Prompt injection

Text on the site under test is treated as untrusted input. When dejav writes test cases from your description, the AI is instructed not to follow instructions found on the site, and dejav checks the pages it reads. When the checks detect instructions aimed at the AI, the scan is intended to stop and the domain is intended to be blocked from new scans or runs. Exploring your site, learning and relearning test cases, and running them are not checked yet, so a page that tries to instruct the AI there does not stop the run or block the domain. Detection is pattern-based and can miss instructions or act incorrectly.

Screenshots, credentials, and audit logs

Screenshot and replay capture can be turned off per project, and captures can be deleted in bulk at any time. Site credentials are encrypted before they are stored. Sign-ins, changes to your projects and account, scans, runs, and billing actions are recorded with who made them and when. Your data export includes what changed and when, without who made it or their IP address. Entries are deleted after 90 days.

dejav is pre-release and holds no compliance certifications yet. The measures on this page describe how dejav is designed to work. They reduce risk but cannot guarantee that every run stays within them; responsibility for what a run does is set out in the Terms of Service.
