Data analyst Chemicals Used the software for: 6-12 months ### "Spectacular vulnerability assessment tool" October 26, 2022 4.0 Nessus has done a spectacular job in vulnerability assessment in our company which has helped us to maintain secure environments in the cloud and on premise. Configuring nessus was a straightforward forward task and it carries out in depth scans within a short time. Nessus comes with build in vulnerabilities which you scan against your systems to find out if there are vulnerabilities present. Pros I like how you get an alert promptly when nessus detects an attack on any of your systems. I also like the wide variety of plug ins made available by nessus for specific vulnerabilities. I'm also impressed with how nessus allows you to create your own tests related to you company. I like how it is always releasing updates on new vulnerabilities which you can check in your systems. Nessus provides suggestions for alleviating detected vulnerabilities in your systems. Cons Nessus still has the issue of false positives which is common in most vulnerability scanners whereby nessus detects vulnerabilities that are not present. It is not user friendly in terms of costs since it is expensive if you want to access more features through the paid versions. Aside from that, I am certain that we have been able to get the best from this tool. Review Source Tushar G.

The setup was easier and application is user-friendly once you get the hang of it. Pros The application is very useful in findings for vulnerabilities in the network assets and reporting them with quality reports containing where exactly the issues are found and its mitigation. The tool updates are very relevant and even reports zero day vulnerabilities for particular software and technologies made use by the network asset. It covers almost all the security issues present in a network device or servers with proper credentialed scans. Cons The application has to be kept up to date for covering all the latest patch vulnerabilities and it lists even ssl and ssh related vulnerabilities for database servers or internal routers, so our team has to identify the necessary findings to report to customer.

Within the company we have deployed Nesss and it really has been helpful to fin every vulnerability that the scans throw at us, the information is very complete from the discovery stages, we feel very satisfied, that the tool has been implemented in other infrastructure and the results are very heplful. Pros Nessus and its graphical interface is attractive, I would say that minimalist but punctual and charming, it is very clean, it should be applauded that in each version they improve it and include some types of scans that can bring you more complete results when you carry out an analysis. It is very remarkable that the plugins in your database are up to date and that your community generates an adequate response on time.

Pros First, it was free for us to use since we a government entity, and I was able to get training on the product. It is relatively easy to use once everything is set up, and it can scan just about anything. Cons The initial setup can be a chore.

Cons The only flaw of Nessus is that if you don't purchase the "Tenable Web App Scanning" subscription, doing authenticated scans on web apps (especially if they implement authentication mechanisms such as SSO) presents problems, since even specifying credentials (or cookies) it can happen that Nessus fails to authenticate.
