"Good overall product with room for improvement"

What do you like best? Nessus includes some good functionality to enable integration with a larger suite of vulnerability management systems and help facilitate some light automation. The performance is generally consistent and the interface is intuitive and easy to use. What do you dislike? The plugins are not always updated in a timely fashion, which results in unnecessary false positives and time spent researching and documenting. The API functionality is tied to a Tenable.io ...

"Great tool for self-assessments and scanning new deployments"

What do you like best? Great interface, portable (I run it on a laptop), and the reporting format has been great for developing a methodology with which I can track my organization's security posture over time. What do you dislike? Very little to dislike here. I think the only thing I'd like to see is a summary interface that does some of my reporting work for me, instead of me having to review the reports and create totals for each vulnerability category (critical, high, ...

"Better than most"

What do you like best? I like the plugin feed, it is very robust. I also like the ability to upload compliance audit files directly from Tenable. What do you dislike? I don't feel like the scanners do a great job of compliance checks, I prefer to use ePO instead of the Nessus scanner to obtain the credential data I need. Could be operator error though ;) What problems are you solving with the product? What benefits have you realized? We are currently resolving FISMA scorecards with the use ...

"Nessus Network scanninhg"

"Nessus is the gold standard for vulnerability scanning."

What do you like best? Nessus offers great support for the platform and the documentation is thorough for an easy implementation and configuration. What do you dislike? The pricing model has changed and some features now require a larger financial commitment or maintaining older versions, which is obviously not desirable for a security and compliance tool. Recommendations to others considering the product: Definitely read the documentation before you get started, it will save a lot of time ...

"Nesssus Rocks!"

What do you like best? The flexibility in scan entire networks and for specific vulnerabilities. What do you dislike? That the free license is no longer available for home and personal use. What problems are you solving with the product? What benefits have you realized? Filling gaps of employment. We don't have the budget for a security team so the infrastructure team fills both roles. Nessus make our jobs easier to scan for vulnerabilities without paying for FTES or yearly pen test.

"Fantastic Vulnerability Scanner"

What do you like best? I liked the simplicity of the readout from the vulnerability scanner What do you dislike? Unfortunately, the only thing I had an issue with was the pricing model. It is priced lower than most, but I am working in a non profit organization where budget is extremely tight. Recommendations to others considering the product: n/a What problems are you solving with the product? What benefits have you realized? Vulnerability of business systems
