Guardium Administrator at Interactive Group

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."

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

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

"Quick assessments, compliance scores, and results are provided without having to do agents."

"Nessus is effortless to integrate."

"The value that Tenable Nessus brings to my company is significant because we can see risks; it is also good to see the pages risk and system risks, and it saves money."

"The solution is great for scanning servers."

"The scanning capabilities are most valuable when compared to Nessus."

"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."

"Tenable Nessus is one of the best vulnerability assessment tools, that I know."

"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."

More Tenable Nessus pros

Cons

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

"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."

"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."

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

"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."

"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 think the reporting templates could be improved with Tenable Nessus."

"I would like to have a management option after the network scanning."

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

"Tenable Nessus could improve the price."

"It would be nice for the professional module to include some of the reports available in the expert module."

"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."

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."

"This solution is affordable."

"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."

"Tenable Nessus is affordable."

"There is an annual license required to use this solution."

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

"In general, it is extremely expensive."

"I would like to see better discounts."

"The price of the solution is reasonable."
