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

"The best part I like is the on-demand scans."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"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."
"Qualys TotalCloud has improved our security posture."
"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"Qualys TotalCloud has significantly improved our organization by automating our reporting processes, reducing the time spent on report creation from two hours to less than fifteen to twenty minutes."
"Qualys TotalCloud has saved our time by giving us better asset visibility and risk-based prioritization, as it has reduced the time spent manually reviewing CVEs and deciding what to address first."
"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."
"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 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."
"I like this solution because it is complete, it can scan and check many types of vulnerabilities, it can also check for compliance, it fits very well in my environment, it is very easy to use, and there is a very good cost-benefit of this solution."
"We can now deliver highly professional consulting using the product."
"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."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"The solution is the most dynamic one I have seen thus far."
"It's scalable."
"The solution provides time saving and cost saving benefits."
"Tenable Nessus is an absolutely stable and fantastic product."
 

Cons

"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"Regarding improvements to Qualys TotalCloud, I suggest that user navigation can be enhanced because initially, many users found it complicated and had trouble understanding the platform due to information being spread across multiple tabs."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."
"There is a lack of data segregation according to criticality or inventory."
"I chose a rating of nine out of ten because there is a complex interface that sometimes overwhelms new engineers."
"We would like to see Windows-based sensors available in Qualys, as this would make the platform more versatile and support a broader range of environments."
"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."
"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 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."
"The scalability of Tenable Nessus is good. However, it could be more flexible."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"The inventory management function in this solution needs improvement."
"In terms of what could be improved, I would say its reporting portion."
"One area with room for improvement is instead of there just being a PDF format for output, I'd like the option of an Excel spreadsheet, whereby I could better track remediation efforts and provide reporting off of that."
"The solution could improve security updates."
"We operate in small and medium enterprises and for them, Nessus is becoming expensive."
"We feel the solution's technical support to be very bad."
 

Pricing and Cost Advice

"The cost is high, but it meets our organizational needs."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"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."
"TotalCloud's price is about right where I would expect it to be."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."

"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
"The pricing is much more manageable versus other products."
"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."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"The price of the solution is reasonable."
"Tenable Nessus is affordable."
"I think the price is fairly affordable. It provides a license that is fair."
