Rule 2 · Action: Audit only + watermark · Trigger: URL visited
Watermarking
Set the rule's URL condition (Contains text string) to
cepdemo.mobi-sec.de — it replaces news.google.com from the guide. When the rule applies,
a translucent watermark renders over everything below.
This block simulates a confidential internal briefing so the watermark has realistic content to overlay:
Synthetic documentPROJECT NORTHWIND — INTERNAL BRIEFING (SYNTHETIC)
Status: Confidential! Not to be shared externally!
Q3 revenue outlook .......... +14.2% vs plan
Citrix migration wave 2 ...... 1,840 seats, ETA Nov 03
Vendor shortlist ............. Alpine Systems / Corvus Data / Helix IT
Decision owner ............... M. Winter, IT Security
- The watermark text “Confidential! Not to be shared externally!” tiles across the page.
- A unique ID and the load date/time appear under the watermark text.
- The ID differs when the same page is opened from a managed browser versus a managed profile — verify both.
- An audit event is written to Chrome log events; navigation itself is not blocked.
