Apply stricter security headers to your own site as you browse it, and read the
violation reports the browser raises. One domain at a time, and only the domains
you switch on.

While a domain is switched on, the toolbar icon carries a badge: i (blue) while
it is only monitoring, ! (red) while it is enforcing a policy that can break the
page.

• Report-Only (default) applies the report-only twins of the recommended
  headers. Additive monitoring, it cannot break the page.
• Enforce strict applies the enforcing headers, so you can see exactly how the
  site would break under the real policy. What gets enforced depends on whether
  you are signed in.
• Violations appear in the page's own DevTools console (opt-in per site) and in a
  log you can download as JSON.

Nothing to sign up for. A built-in strict baseline is applied in Report-Only, and
every violation it raises is logged in your browser.

Enforce strict applies your custom header overrides and nothing else. The built-in
baseline is a monitoring tool: enforcing it is a decision about your site.


Signed in at https://app.tardisec.com, it fetches that domain's recommended
security headers from your account and applies them in both modes. That set names
a reporting endpoint, so the browser delivers violation reports to your account as
well as to the in-browser log.


By default:

• Does nothing until you switch monitoring on for a domain. Installing it changes
  no page, and there is no default-on list.
• Does not log to the page console. You can turn that on per site.
• A domain's settings are discarded once every tab for it is closed. Tick
  "Remember these settings for this domain" and they persist until you switch the
  site off. The report log is held in memory for the browser session, and the
  popup can clear it at any time.

Violation reports are produced by the browser's own Reporting API, not by this
extension. They go to whatever endpoint the headers being applied name: your
account's collector when signed in, and no endpoint at all on the built-in
baseline, where reports never leave the browser. No analytics, no telemetry.
