Immediate results in patching promptly address vulnerabilities
When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task. It would be easier if Tanium provided the patches directly. Some other brands provide the patch with a direct download link, which facilitates the process. Also, I feel that if there were more detailed documents and remediations readily available online for troubleshooting, especially more up-to-date information, it would be beneficial. Currently, some resources online are very out-of-date.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of this solution are the consolidation of all historical data on device endpoints, security drivers, firmware, and Software version gaps."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."
"The product is granular and can build complex roles compared to other EDR vendors."
"The solution's technical support is very responsive."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"Tenable Nessus is an absolutely stable and fantastic product."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"The most valuable features of Tenable Nessus are the scanning option. Advanced scanning is highly useful. The offline config audits and application assessments are useful."
"The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis."
"It provides multiple recommendations towards the remedy of vulnerabilities."
"The features I personally like include host discovery."
"I have found the vulnerability assessment and the reports to be useful."
"The most valuable feature is the installation of Tenable which is incredibly easy."
 

Cons

"The main issues are the network connection because different customers have issues with their networks. It's difficult implementing this type of solution because the network is the main feature in the architecture for these types of solutions. Tanium could improve by creating some network optimization."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"The most painful thing is the interface. It's a bit unclear sometimes."
"They could improve the UI."
"The solution can give a lot of false positives."
"We had some issues with the solution's OS upgrade."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"It is not really additional functions, or the features that are needed, rather the complexity would be reduced based on the number of modules required to put together a comprehensive operational security and risk compliance model."
"The reporting feature needs to be improved."
"Lacks some penetration testing-related services."
"Model OS costs (and its segregation schema for individual modules)."
"There should be a possibility to install agents on scanned machines. Tenable IO provides the capability of using local agents to check local problems, but this feature is not there in Tenable Nessus Professional. It would be nice to have something similar in Tenable Nessus Professional. We should have the capability to use local agents installed on the machines to locally check a problem."
"The tool needs to upgrade asset tracking."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
 

Pricing and Cost Advice

"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"It is higher than some competitors in the market."
"The solution offers value for money."
"The solution is expensive but it's a good investment."
"It's an expensive solution. It would be nice if the cost were lower."
"There is an annual license required to use this solution."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
"It has a fair cost and very good cost-benefit ratio."
"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"When comparing the price of Tenable Nessus to other similar solutions, such as Acunetix, Tenable Nessus is not as expensive. It is averagely priced in the market. We pay for the solution annually."
"The is a free version of Tenable Nessus available."
"The pricing is much more manageable versus other products."
"Our organization is huge so our license costs $30,000."
"The price is reasonable."
