Likelihood to Recommend Nessus is perfectly suitable for performing comprehensive vulnerability assessment scans being a vulnerability scanner. It is less appropriate for performing penetration testing since it is not a penetration testing tool, it does not have the ability and modules to exploit the vulnerabilities of the system.
Read full review I've been using this product since it began as an open source product, I really like it and for the money, I think it's probably the best choice for most companies who need a product like this. Over the years I've seen the interface change quite a bit and sometimes I think it's a bit unclear how to do certain things and the different packages can be confusing, these are the only reasons I'm giving it a 9 instead of a 10.
Read full review Pros With Nessus we can find the missing critical patches for a server or workstations. Nessus points out any vulnerable or outdated software Technologies used in the system, thus eliminating any chances for security flaws being turned up. Nessus typically points any configuration level issues in accordance with the OWASP guidelines. Even the configuration of SSL related which are most of the time handled by some vendors or 3rd parties. Nessus not only lists out these Vulnerabilities but describes clearly the vulnerabilities in details with its thousands of plugins updated regularly, the tool also recommends solution with practical details of easy implementation. Read full review Setup of the internal scanner was fairly simple and straight forward. An update came out for the internal scanner that allows you to add an Internal Certificate Authority for lookup. Has automated reporting to keep executives and compliance departments informed. Internal scanner can be configured to auto-update itself. "Recast Rules" allows your organization to redefine a vulnerabilities' classification, if it is not applicable or your disagree. External PCI scans allow you to remediate before submitting to Tenable.io for review. Tenable.io staff was very patient and helpful. They provided some limited guidance with remediation. Internal and External scans can be automated. schedule for the automated scans is very granular. Read full review Cons Could use an upgrade within reports. Scans can take a long time to complete. Have to break them down in small sections. Read full review Expensive - You do pay a slight premium for the best product in the space. Asset management is difficult to work with if you have a lot of asset turnover, the license can be ''held'' for 3-6 months after the asset is gone from your environment. Read full review Likelihood to Renew Nessus is best and easy to use application for Vulnerabilities finding and reporting, it has multiple platforms and wide scope covering almost all devices for security improvement so far, thus we are very likely to continue its services.
Read full review We like to renew tenable each year we have had it so far.
Read full review Usability It's very much a plug and play application that the user can go into with limited knowledge and set-up scans in minutes.
Read full review Support Rating I haven't needed to contact support yet. But issues are easily solved with a quick internet search which means support and by extension, the larger community are involved and knowledgeable.
Read full review Support is usually really great at walking you through any steps you need to take when you get stuck on something. There are a few false positives and errors that have come up over the years that required their help to get through. Unfortunately, the steps required to diagnose some problems are more tedious than I think should be necessary. (IE: SQL instances can throw errors that clog up your logs because one plugin affects it in a certain way. The process to diagnose this is to watch timestamps of plugins in a log while monitoring the SQL logs at the same time and using your best guess as to what is causing it.)
Read full review Alternatives Considered Sometimes when we identify a vulnerability with Nessus that has an exploit, we made a proof of concept with
Metasploit in order to show to the IT managers the importance of the software/hardware hardening.
Read full review Tenable.io has a comparable set of features, with excellent support and a competitive price. After less than desirable experiences with another company, we moved to Tenable and haven't looked back since.
Read full review Return on Investment Nessus certainly has a positive impact while me while performing my job, either as security research, or performing vulnerability assessments for clients. It gives a lot of information about the system/application after performing scans. The number of false positives is also less compared to other vulnerability scanners. The professional edition is very useful as policy templates available in this edition are very handy and useful even to perform compliance scan like PCI DSS scan. Also, the ability to export the scan results into reports in formats like HTML, PDF is very useful which could be for performing system/application reviews. Read full review Since this is a requirement for our PCI compliance and the cost is relatively low, the ROI isn't really something we need to think too much about, Tenable's pricing is fair and affordable.
