Frequently Asked Questions About Signal
Do I really need Signal?
If you use the internet (and you do), some level of cybersecurity protection is important. Signal helps protect against threats that most people do not see coming - like phishing emails, data breaches, and malware. The free tier is a good place to start.
Will Signal slow down my computer?
Modern cybersecurity tools are designed to run quietly in the background. Signal should not cause noticeable slowdowns during normal use. If it does, check the settings for a lighter scan mode.
Can Signal protect me from all threats?
No single tool stops every threat. Signal handles its specialty well, but a complete security setup also includes strong passwords (use a password manager), two-factor authentication, and keeping your software up to date.
