Though you may know and follow basic security measures on your own when installing and managing your network and websites, you’ll never be able to keep up with and catch all the vulnerabilities by yourself.<\/p>\n

Vulnerability scanners can help you automate security auditing and can play a crucial part in your IT security. They can scan your network and websites for up to thousands of different security risks, producing a prioritized list of those you should patch, describe the vulnerabilities, and give steps on how to remediate them. Some can even automate the patching process.<\/p>\n

Though vulnerability scanners and security auditing tools can cost a fortune, there are free options as well. Some only look at specific vulnerabilities or limit how many hosts can be scanned but there are also those that offer broad IT security scanning.<\/p>\n

  1. Nessus Essentials<\/strong><\/li>\n<\/ol>\n

    Nessus Essentials<\/a>, formerly Nessus Home, from Tenable allows you to scan up to 16 IP addresses at a time. The company offers a 7-day free trial of its profession edition<\/a>, which can perform unlimited IP scanning and also adds compliance checks or content audits, live results, and the ability to use the Nessus virtual appliance.<\/p>\n

    Nessus Essentials installs on Windows, macOS, and a variety of Linux\/Unix distributions. On the web GUI, you can easily see which scanning types are included–host discovery plus vulnerability scans. You\u2019ll also see, listed but inaccessible, scan types that are available in the profession edition: vulnerability scanning for mobile devices and compliance scanning.<\/p>\n

    With the free edition you can schedule one auto scan, but that\u2019s not a restriction with the professional edition. You can also configure email notifications, discovery settings, assessment and report preferences, and some advanced settings. You can also review plugins and the vulnerabilities or exploits they are looking for related to the scan. After a scan runs you can access an overview of what it found on each host and dig down to details about vulnerabilities and possible remediations.<\/p>\n
