Ostral sees the extension
Browser extensions run unvetted code with deep permissions, and most are installed without IT ever knowing. Ostral gives you a full inventory of what's running across your fleet, and what each one can actually access.

One update is enough to turn a vetted tool into an infostealer. A continuous monitoring is now necessary.
