Improvements sought in database optimization while benefiting from robust security monitoring

We use the analytical functionality of Guardium, but the analytical functionality is not so powerful or flexible because it does not include the application user ID. It only includes the database user ID. To identify risky users, it does not support end users, so IBM must incorporate this feature into the built-in analytical engine of the Guardium. There is only one problem I experienced while using Guardium: the internal database of the collector is MySQL, which is not so powerful or flexible. When you make a query in a MySQL database, it takes too much time to respond. IBM should replace this MySQL database with a more powerful internal database for the logging mechanism so that Guardium can collect logging data flexibly and ensure optimization. My overall experience with Guardium is good. The only problem is that IBM must replace the internal DB, MySQL, with a more powerful enterprise-level database because enterprises use it at an enterprise level, and MySQL does not support optimally.

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 feature is that it provides a simple English recommendation on actions that you need to take once a vulnerability is discovered."

"It helped with some of the regulatory requirements. It also helped with some of the security analytics and analysis. It was worthwhile from that perspective."

"The Vulnerability Assessment feature is quite stable and helps identify numerous vulnerabilities in databases."

"The best feature is that you can see the activity in your data environment and have the ability to get the vulnerability assessments done quickly with scores that can be compared."

"The most valuable feature is that it provides a simple English recommendation on actions that you need to take once a vulnerability is discovered."

"The reporting features are good and there are many built-in reports that can be quickly configured."

"It helped with some of the regulatory requirements, and it also helped with some of the security analytics and analysis, making it worthwhile from that perspective."

"The most valuable feature of Tenable Nessus is vulnerability detection."

"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."

"The features of Tenable Nessus that I have found most valuable are its reliability and its ability to collate a dependable output, where we are able to get the same vulnerability when we test manually."

"The interface is excellent; it makes it very user friendly and easy to navigate for the most part, and the product is pretty problem-free so we don't have any real issues with it."

"Its initial setup was simple and straightforward."

"With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device."

"I can say that I am satisfied with Tenable Nessus' support and customer relations, which is why I'm still with the solution."

More Tenable Nessus pros

Cons

"The only problem is that some of the reports come up with blanks and missing data."

"The interface could be improved by having sub-groups of tests, ultimately making the process of collecting tests faster."

"Building policies is not that easy. There are some things that are turned off by default, for example, displaying values."

"The interface could be improved by having sub-groups of tests, ultimately making the process of collecting tests faster."

"It was not as easy to use. The user-friendliness of it was somewhat lower than what I was expecting. It was also lacking in terms of the ease of the setup. There should be an automatic agent for deployment."

"I wouldn't use it. That would be my advice to others looking into implementing IBM Guardium Vulnerability Assessment."

"There is only one problem I experienced while using Guardium: the internal database of the collector is MySQL, which is not so powerful or flexible."

"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."

"They could make their reporting a little better."

"The interface is a little bit clunky, and the reporting is not marvelous. There should be better integration of reporting between instances. Currently, the instance stands alone, and it produces a report. Being able to amalgamate those reports with another instance will be useful."

"I would like to see more on the automation side."

"The reporting could be improved. The reporting in Rapid7 is much better."

"There is room, overall, for improvement in the way it groups the workstations and the way it detects, when the vulnerability is scanned."

"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."

"Tenable Nessus is not feasible for a large company."

More Tenable Nessus cons

Pricing and Cost Advice

"One thing not advantageous for it was that it was a little bit more expensive. I would rate it one out of five in terms of pricing."

"It has a fair cost and very good cost-benefit ratio."

"I think the price is fairly affordable. It provides a license that is fair."

"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."

"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."

"I would like to see better discounts."

"The solution is worth the cost. It's a good investment."

"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."

"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
