When it comes to OpenVAS vs Nessus, there are important differences that will help you decide which vulnerability scanner is right for you. While both are among the top tools out there, they are not the same.
According to managed IT security experts Fusion Computing Limited, choosing OpenVAS vs Nessus may come down to your budget, your security goals, and your expertise, so keep reading to find out which is right for you.
1. What is OpenVAS?
OpenVAS is a free, open source vulnerability scanner that’s very configurable and is definitely one of the top VAS (Vulnerability Assessment System) on the market. It comes with plenty of documentation and tutorials on how to use it, and it ideal for small businesses that want a vulnerability scanner but that can’t afford a high price tag. It’s also a great option for those looking to try out a vulnerability scanner without making an investment first.
2. What is Nessus?
Nessus is a proprietary tool, meaning it isn’t free but this comes with added benefits like added features, regular professional upgrades and maintenance, customer support, and more. The program also boasts more CVE coverage, fewer false positives, ease of use, live results, report generation, and more. A great function of Nessus is that it doesn’t just scan for vulnerabilities, but also suggests solutions for them, which is an impressive feature.
3. Which is Right for Me?
In terms of OpenVAS vs Nessus, both are great, useful tools for scanning vulnerabilities. However, one might be better suited for your needs as there are some key differences between the two. The cost of Nessus is sometimes a disadvantage, especially if you don’t have a large budget for security. However, paying for the program allows it to have some useful features and functions that an open source program simply can’t match and a cyber security breach is not something you can put a price tag on.
Another differentiator is that Nessus is a highly advanced tool that requires some expertise to use to its fullest. It might be a good option to try out OpenVAS first to get the hang of a VAS before investing in Nessus. If security is your main priority, Nessus does have more CVE coverage and may find more vulnerabilities than OpenVAS, so it may be worth the investment for you.
OpenVAS vs Nessus isn’t an apples to apples comparison. Both tools are popular and highly functional, but one might be better for you depending on what you’re looking to achieve. At the end of the day, a vulnerability scanner is a smart choice and you certainly can’t go wrong with either option.
