Vulnerabilities stop here

GreerGuard monitors behavior and dangerous permissions utilized by software and websites. Providing solutions to the biggest problems seen in consumer IT.

Screen-Lock Attacks
Detects and breaks computers free from webpages that traps a user in full-screen, blocking cursor and keyboard inputs with instructions to call a scam number or execute a malware script.
Potentially Unwanted Apps
Scans installed apps for dangerous permissions and monitors for permission changes post-update. Checks for hidden behavior, and known threat indicators such as: displaying over other apps.
Suspicious Extensions
Audits your installed browser extensions and flags ones with overly broad permissions or unknown publishers. (Many free browser extensions gather revenue somehow, either by selling data or tapping into session cookies to get a commission from your online purchases.)
