The developer version of Webbkoll now detects report-to and report-uri directives in the Content-Security-Policy header of websites. Webbkoll shows if CSP reports are sent to a third-party endpoint. Similar HTTP headers will be detected in the future.

Test it yourself:

We originally suggested this feature (see for further information).

Jitsi Meet's default landing page:

As an admin, you should remove or modify the default text of your landing page since it incorrectly states that Jitsi calls are fully encrypted.
We already reported this (

The screenshot shows this incorrect statement in German. In this example, the admin decided to mention the absence of full encryption somewhere in the privacy policy. This could be far more prominent and transparent.

To Jitsi admins:

– Add a privacy policy (or a link to it) to your landing page.
– Be aware of Google STUN servers in your configuration (see also
– Change the default text of the landing page since it may incorrectly state that Jitsi is fully encrypted.
– Try to deploy HTTP security headers, like a strict Content Security Policy.
– Keep your server software up-to-date (see also
– Be nice to each other.

Follow-up post regarding Jitsi instances:

We briefly checked the landing pages of 72 public Jitsi instances:

– 92% didn't contain a link to a privacy policy.
– 10% contained tracking code, like Google Analytics.
– Only 11% didn't embed tracking code AND linked to a privacy policy that likely meets requirements of the GDPR.

Zoom vs. Jitsi:

– Neither Zoom nor Jitsi are always end-to-end encrypted.
– Zoom and Jitsi apps and the web clients contain trackers/tons of JavaScript.
– Zoom's privacy policy has some issues, but the vast majority of Jisti instances has no privacy policy at all.

Always talk about pros and cons. Don't skip the drawbacks of so-called "alternatives."
