GOOD QUESTIONS
A little more
understanding.
A few things to know before getting started.
Is JustSafe free?+
Yes. JustSafe is free to use.
What can I check with JustSafe?+
Links, messages, and files. Share or paste the content into JustSafe and review the result and its scope. Platform capabilities can differ.
Does every warning mean a website is malicious?+
No. A warning can indicate suspicious signs or an incomplete check. Read the explanation, verify through an official source, and avoid sharing sensitive information when unsure.
Do I need to change the apps I use?+
No. The concept is to check content from the apps you already use, through sharing, pasting, or supported browser protection. JustSafe adds protection; it is not a replacement for the apps you already use.
What should I do if I receive a suspicious message?+
Avoid opening links or sharing personal or payment details. You can check the message or link with JustSafe. Verify the request through the official app or website by opening it yourself.
