No CDNs, no data collection! It runs entirely on Atlassian’s infrastructure.

"Quishing", or QR-code phishing, is on the rise!

www.QRTrust.fyi is a web app I made that you can use on your Android or iOS phone to scan QR codes and find out if the website they link to is suspicious. It works by checking each url against the crowd-sourced PhishTank database!
