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 provides unified vulnerability and threat assessment for IaaS and SaaS and a single prioritized view of risk, which helps reduce my workload by not having to combine multiple sources."

"I would rate Qualys TotalCloud ten out of ten."

"If someone were to ask me to review Qualys TotalCloud, I would summarize it as an end-to-end solution for cloud security with visibility and governance-grade controls without needing to manage multiple disconnected tools."

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

"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."

"Generally, Qualys is very good at detections, whether on cloud or on-prem, and the agent allows deployment on both infrastructures, providing continuous monitoring of your assets, which is a key selling point for us."

"Qualys TotalCloud is an excellent platform, and the beauty of the platform is that we can get all the vulnerabilities, see all the reports in a single dashboard, view them segregated, and easily learn about critical, high, and medium findings with appropriately provided remediation steps."

"The best features in Qualys TotalCloud include the total asset management of the cloud environment. It is very easy to export the report and see the vulnerabilities related to the cloud specifically."

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 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. It also helped with some of the security analytics and analysis. It was 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 results are not that bad, but the key selling point is that it is an affordable tool set."

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

"Tenable Nessus is cheap and flexible."

"My advice to people who are looking into implementing this product would be to just go ahead and do it."

"Tenable Nessus is an absolutely stable and fantastic product."

"Nessus is effortless to integrate."

"To me, that was a better selling point because it was real: it wasn't demo data, it was our own network showing, "Hey, we're vulnerable because of this, and here's the tool that did it," which got us the buy-in we needed from upper management."

"We have around 500 virtual machines. Therefore, we conduct monthly scans and open tickets for our developers to address identified vulnerabilities. These scans cover the servers, other network equipment, and appliances in our infrastructure."

More Tenable Nessus pros

Cons

"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."

"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."

"Qualys TotalCloud needs to enhance its scanning capabilities in the IP domain, as it currently lacks the functionality to resolve IPs to their corresponding domain names."

"The downside is only in container security, but it has not been a long time since they introduced these models."

"There is room for improvement in vulnerability scanning, particularly for PaaS environments. Currently, Qualys does not have full access to these instances, which limits its effectiveness."

"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."

"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."

"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."

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

"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 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."

"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."

"The professional version is not very scalable."

"In Nessus Professional, the main drawback was that we could have a single-user login password. So it could be better in terms of security."

"The most that Tenable Nessus could improve is its speed because they might have put a lot of effort into compatibility issues that downgrade the speed."

"We'd like to see more integration potential within the solution."

"There is room for improvement in finishing the transition to the cloud. We'd like to see them keep on improving the Tenable.io product, so that we can migrate to it entirely, instead of having to keep the Tenable.sc on-prem product."

"Based on my experience, the pricing for Tenable Nessus is somewhat higher, but customers still want to pay for it, so it remains acceptable."

"Vulnerability recommendations are outdated and not in line with industry standards."

"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."

More Tenable Nessus cons
