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 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."

"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 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."

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

"Personally, I think Nessus is quite a good product."

"The solution can conduct a full vulnerability assessment and also suggest mitigation of vulnerabilities and has a lot of other features."

"Nessus has greatly improved the security of our clients' networks."

"The solution is easy to understand for users because instructions are included on the platform."

"The most valuable aspect of this solution is that you receive the entire report, which details the breakdown, especially in terms of critical, high, low, and mediums."

"The support has been really cooperative."

"We can now deliver highly professional consulting using the product."

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

More Tenable Nessus pros

Cons

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

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

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

"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."

"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."

"Pricing is one of the most important features, and it is something that they can improve on."

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

"Multiple user access would be an area for improvement from a user-access perspective. A role-based access control feature would be great because at present, there is a limitation with only one account. If that account gets compromised or gets locked, then we will encounter problems."

"We find that some devices aren't pinged and the scans aren't done properly."

"The professional version is not very scalable."

"Scans aren't done properly and some devices aren't pinged."

"It wasn't very clear how the scripts are running the scans. There's information about the script but it's not straightforward. The script information for each of the plugins should be available, but it doesn't give us straightforward direct information about how it was executed. That needs to be more clear."

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

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."

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

"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."

"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."

"The pricing is much more manageable versus other products."

"The solution has free options."

"The price of the solution is reasonable."

"We paid about six thousand dollars per license."
