Prezenz Web Guard Firefox

Prezenz Web Guard

Blockiert Ablenkungen während Prezenz-Sessions.

Features & Capabilities

Prezenz Web Guard ist die Browser-Komponente der Prezenz Desktop-App – einer Fokus- und Klassenraum-Lösung für Schulen im BYOD-Kontext (Bring Your Own Device). Während einer aktiven Fokus-Session blockiert die Erweiterung in Echtzeit jene Webseiten, die im jeweiligen Profil als nicht erlaubt definiert sind, und ersetzt sie durch eine neutrale Sperrseite.

WIE ES FUNKTIONIERT Die Erweiterung kommuniziert ausschliesslich mit der lokal installierten Prezenz-Anwendung über eine Native-Messaging-Bridge. Sie holt sich von dort die für die aktuelle Session geltenden Regeln und blockiert entsprechend. Ohne aktive Prezenz-Session greift die Erweiterung in nichts ein.

DATENSCHUTZ

  • Es werden keinerlei Browserverläufe, Suchanfragen oder Inhalte besuchter Webseiten erfasst, gespeichert oder gesendet
  • Es findet keine Kommunikation mit externen Servern statt – ausschliesslich mit der lokalen Prezenz-App auf demselben Gerät
  • Die Erweiterung ohne installierte Prezenz Desktop-App hat keine Funktion

Is Prezenz Web Guard Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Prezenz Web Guard requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ****** ********* ** * ****** ******** ******** ********** * ******* ******* *****
  • Medium *********** ************* ******* ********** *** ****** ************* ******* *** **** ** ******* **********
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Prezenz Web Guard is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.

Risk likelihood analysis details
  • High This extension was recently updated in the past month. New updates may not be stable or safe.
  • High **** ********* *** *** **** ****** ********* ********** *** *** ** ****** ** *****
  • Medium **** ********* *** ***** ** *** **** * ******* *** ********** *** *** ** ****** ** *****
