Frequently Asked Questions About Nessus
Do I really need Nessus?
If you use the internet (and you do), some level of cybersecurity protection is important. Nessus 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 Nessus slow down my computer?
Modern cybersecurity tools are designed to run quietly in the background. Nessus should not cause noticeable slowdowns during normal use. If it does, check the settings for a lighter scan mode.
Can Nessus protect me from all threats?
No single tool stops every threat. Nessus 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.
