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.

Hybrid deployments have strengthened vulnerability visibility and streamlined security reporting
I would not personally speak to what I like about Tenable Nessus, because I think the only reason many customers are using it is because it is well-known and they have received directives from their companies or mother companies. For me, the key value is the ease of use and integration with SIEMs because it has built-in integrations with IBM QRadar and others. Tenable Nessus is typically a widely integrated tool within the existing security ecosystem. It is part of the security policy that customers have implemented, so it does provide positive impact and is beneficial to use Tenable Nessus.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The scalability is good as well. I would rate it ten out of ten."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"TotalCloud has been excellent in providing us with immediate access to all the products and features we need, such as CSPM, TruRisk Insights, and compliance reports, including CIS and HIPAA."
"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"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."
"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."
"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"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."
"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 reporting features are good and there are many built-in reports that can be quickly configured."
"The vulnerability scanner is the most valuable feature."
"The initial setup is very straightforward."
"The value that Tenable Nessus brings to my company is significant because we can see risks; it is also good to see the pages risk and system risks, and it saves money."
"Personally, I think Nessus is quite a good product."
"Nessus' most valuable feature is vulnerability management because it helps to discover vulnerabilities proactively and integrates with patch management solutions so you can push patches."
"You can then direct your team to create a report on the discovered vulnerabilities."
"The setup is straightforward, it takes about five to ten minutes to deploy and it is easy."
"Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."
 

Cons

"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"
"The downside is only in container security, but it has not been a long time since they introduced these models."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"Qualys TotalCloud has some features where reports have limitations for downloading."
"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's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"Customer support with Qualys TotalCloud needs a little improvement with the response times."
"The improvement needed in Qualys TotalCloud is mainly in the artificial intelligence automation agents, where we can customize and create what meets our needs, not necessarily having to use those provided in the tool."
"The only problem is that some of the reports come up with blanks and missing data."
"Building policies is not that easy. There are some things that are turned off by default, for example, displaying values."
"I wouldn't use it. That would be my advice to others looking into implementing IBM Guardium Vulnerability Assessment."
"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."
"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."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."
"The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."
"There is room, overall, for improvement in the way it groups the workstations and the way it detects, when the vulnerability is scanned. Even when we would run a new scan, if it was an already existing vulnerability, it wouldn't put a new date on it."
"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
"While the solution is great for scanning servers, its features are limited when it comes to scanning network devices for vulnerabilities."
"Tenable Nessus provides observations but offers limited information about solutions."
"They should improve the I/O reporting and the customized spreadsheet export feature."
 

Pricing and Cost Advice

"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"The cost is high, but it meets our organizational needs."
"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 pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"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."
"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."
"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."
"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."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"The solution has free options."
"The price of Tenable Nessus could improve, it is expensive."
"This solution is affordable."
"Our organization is huge so our license costs $30,000."
