Sr Security Engineer at a tech vendor with 5,001-10,000 employees
Risk-based triage has transformed container security and now prioritizes high-impact threats
The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

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's most valuable features are its security capabilities that help identify and mitigate risk factors."
"Its dashboards are brilliant. It provides in-depth insights."
"The most valuable feature of Qualys TotalCloud is the visibility it provides."
"I would rate Qualys TotalCloud ten out of ten."
"I rate the breadth of FlexScan in providing visibility into on-premises, multicloud, and container environments as fantastic."
"I found the initial setup user-friendly."
"Its excellent graphical interface makes the scanning process simple."
"The biggest strengths of Qualys TotalCloud are that it is pretty good at cloud visibility, has easy integration, and also has multi-cloud compatibility."
"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 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 scanner is the most valuable feature."
"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."
"You can then direct your team to create a report on the discovered vulnerabilities."
"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three."
"Tenable is the best vulnerability management product in the world, and I recommend it."
"The features I personally like include host discovery."
"A valuable feature of the solution is that it is easy to understand."
"The most valuable feature of Tenable Nessus is vulnerability detection."
 

Cons

"The price is very expensive, actually."
"There should be improvement from a dashboard perspective when collecting and showcasing data to lead management."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"I would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."
"Their support could be improved."
"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."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."
"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."
"I wouldn't use it. That would be my advice to others looking into implementing IBM Guardium Vulnerability Assessment."
"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."
"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."
"I face issues with Tenable Nessus sometimes due to upgrades."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"Consumes more system resources when it's running."
"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 professional version is not very scalable. It's not really scalable considering the number of assets and clients that I have."
"The product must be more comprehensive."
"Tenable Nessus is not feasible for a large company."
 

Pricing and Cost Advice

"Qualys TotalCloud offers cost-effective licensing flexibility."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"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."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"The cost is high, but it meets our organizational needs."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"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 price of Tenable Nessus could improve, it is expensive."
"The solution has a single price for unlimited assets."
"The pricing is much more manageable versus other products."
"This solution is affordable."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."
"In general, it is extremely expensive."
"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."
