Unified risk scoring has improved our cloud visibility and simplifies remediation priorities

Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

Dr. Sajid Latif

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

"Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution."

"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."

"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."

"The scalability is good as well. I would rate it ten out of ten."

"With TotalCloud, we can scan through the API. If we are not able to deploy cloud agents on the machine, we can use the API."

"The most valuable feature is extensibility."

"Qualys TotalCloud helps you not just to identify misconfigurations, but you can actually also fix issues."

"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."

More Qualys TotalCloud pros

"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 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."

"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."

"Tenable Nessus streamlines the process of scanning for our organization."

"Once you get past the initial implementation, the solution is very stable."

"What I like most about Tenable Nessus is its vulnerability scanning feature."

"I have experience with it on my attack stations, and it's pretty good to optimize. Personally, I think Nessus is quite a good product."

"The features I personally like include host discovery."

"I have found the vulnerability assessment and the reports to be useful."

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

"Tenable Nessus is good. It's the best vulnerability solution in the industry."

More Tenable Nessus pros

Cons

"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."

"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."

"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."

"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."

"There should be improvement from a dashboard perspective when collecting and showcasing data to lead management."

"It has been working very well, but it would be helpful if the dashboard could generate reports tailored to specific compliance needs. For example, in India, we have to comply with RBI and SEBI guidelines. It w"

"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."

"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."

More Qualys TotalCloud 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."

"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."

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

"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."

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

"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."

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

"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."

"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."

"The solution should be able to support more devices."

"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."

"The scalability of Tenable Nessus is good. However, it could be more flexible."

"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."

More Tenable Nessus cons

Pricing and Cost Advice

"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."

"I am not sure about the pricing. From what I understand, it is a bit on the higher side, but I do not have the exact numbers."

"The cost is high, but it meets our organizational needs."

"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."

"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."

"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."

"Qualys TotalCloud offers cost-effective licensing flexibility."

More Qualys TotalCloud 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."

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

"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."

"The price is reasonable."

"The is a free version of Tenable Nessus available."

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