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.

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

"One of the most valuable features of Qualys TotalCloud is FlexScan, which is specifically for internet-facing VMs. We found this feature to be very useful. It was a key differentiator for us."

"I found the initial setup user-friendly."

"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."

"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."

"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."

"The most valuable feature of Qualys TotalCloud is the visibility it provides."

"I highly recommend Qualys TotalCloud to other users."

"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."

More Qualys TotalCloud pros

"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 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."

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

"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 scanning capabilities are very good."

"The solution provides time saving and cost saving benefits."

"My favorite part about Nessus is that you can customize the tool to scan exactly what you want. Microsoft releases new patches monthly on Patch Tuesday, and a lot of companies track that date. I set up Nessus for the day after Patch Tuesday to see which devices have already pushed those updates from Microsoft, so we can stay updated."

"The best features of Tenable Nessus include its compatibility with other applications such as SIEM and other apps, allowing Tenable Nessus to work smoothly with them."

"The setup is straightforward, it takes about five to ten minutes to deploy and it is easy."

"It is a mature tool."

"Nessus has more plugins/add-ons, tests, and templates than previous tools and it is faster and customizable using CLI/API features, offering enough resources for an interesting cost-benefit rating and fewer false-positive events per type of asset while helping us quickly produce a QuickWin report that guided vulnerability management actions and plans for the next three to five years using the same tool, investment, and team for all companies in the group."

"So far, I am quite pleased with this product and don't have any complaints."

More Tenable Nessus pros

Cons

"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."

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

"The response part of the Cloud Detection and Response (CDR) module can be improved."

"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."

"The support is not up to the mark and seems to be overburdened."

"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."

"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."

"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."

More Qualys TotalCloud cons

"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."

"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 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."

"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."

"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."

"The price could be more reasonable. I used the free Nessus version in my lab with which you can only scan 16 IP addresses."

"Model OS costs (and its segregation schema for individual modules)."

"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."

"Multiple steps to create an actionable plan will be a great addition to Nessus."

"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."

"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 professional version is not very scalable."

More Tenable Nessus cons

Pricing and Cost Advice

"Qualys TotalCloud offers cost-effective licensing flexibility."

"Its price seems higher compared to other tools, but it is worth it. If they could adjust the pricing and make it comparable with other tools, that would be great."

"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."

"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."

"Qualys TotalCloud is expensive."

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."

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

"Although Qualys TotalCloud is relatively expensive due to its unique automation features, its cost-effectiveness is rated an eight out of ten, with ten being the most costly."

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

"We paid about six thousand dollars per license."

"I would like to see better discounts."

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

"The price of the solution is reasonable."

"This solution is affordable."

"Tenable Nessus is affordable."

"Cost-wise, it's an affordable tool."
