Answer 1

Nessus scanner is the only one step to find vulnerabilities because it creates an alert whenever there is any malicious attack on the device or if detects any intrusion. By using Nessus you can customise your own vulnerability checks that you want to include into th tool. You can check what type of checks are being done by Nessus and if there is no threat to your Privacy.

Nessus scanner can be inaccurate in the following scenarios:

1) When it is trying to detect any intrusion from a firewall

2) If you running a scan on your device without any credentials then it can yield less results as compared to having a credential

3) If the device you are using lacks the plugin required then you may need to rebuild the plugin otherwise it will produce the wrong result
