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.

Centralized policies have improved remote endpoint control and have simplified data visibility

The integration is not simple and easy. It requires experienced users or people who have done the implementation. When certain policies are applied, they do not immediately push the policies. For example, we manage endpoint device USB access. We set a policy to block it, but it does not come into effect immediately. Sometimes it takes three or four days for it to reflect. That is a pain point. I have raised this issue with support as well, but they said that I need to limit the number of devices in the policy. In terms of application deployment, for us, it was seamless.

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

"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."

"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 platform's unified view of the organization proves particularly valuable for leadership team meetings."

"TruRisk Insights is the most important innovation they've released this year."

"We were able to realize its benefits within 24 to 48 hours."

"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."

"In my opinion, this is the best tool."

"I would definitely recommend Qualys TotalCloud to other users."

More Qualys TotalCloud pros

"Tanium's most valuable features are patch management, inventory, and distribution software."

"Tanium is stable and it is also lightweight."

"The security features are very valuable."

"I like the fact that you can create patching campaigns depending on the area of your network that you want to address first. I like the ability it has to make several campaigns that work in parallel."

"I would say Tanium is the best tool for vulnerability management."

"The insights we gain from our endpoints and the management capabilities that Tanium provides have been a boon to our operations and security."

"Tanium's most valuable feature is its instant discovery aspect."

"Tanium is used for endpoint management, specifically patching and configuration management."

More Tanium pros

"The automatic scanner and scheduler are pretty cool."

"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."

"The most valuable feature of Tenable Nessus is real-time monitoring."

"The most valuable features of Tenable Nessus include its ease of access and quick usability."

"The product's most valuable features are vulnerability and asset management. It can define the rules and validate the configuration."

"You can then direct your team to create a report on the discovered vulnerabilities."

"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."

"Vulnerability assessment is the most valuable feature in Tenable Nessus, as it provides brief details regarding the vulnerability issues we have in our network."

More Tenable Nessus pros

Cons

"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 should be improvement from a dashboard perspective when collecting and showcasing data to lead management."

"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."

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

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

"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."

"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."

More Qualys TotalCloud cons

"Our biggest issue with the solution is its lack of mobility."

"The solution can give a lot of false positives."

"The most painful thing is the interface. It's a bit unclear sometimes."

"There are downsides and drawbacks in Tanium, and there is room for improvement from my perspective."

"We set a policy to block USB access. The moment a device is being set up on the network, I apply the policy, but it does not come into effect immediately."

"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."

"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."

"Tanium’s scalability could be improved."

More Tanium cons

"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."

"EQA's and dashboards should be addressed in the next release."

"The reporting could be improved. The reporting in Rapid7 is much better."

"Tenable Nessus could improve the price."

"The interface is a little bit clunky, and the reporting is not marvelous. There should be better integration of reporting between instances. Currently, the instance stands alone, and it produces a report. Being able to amalgamate those reports with another instance will be useful."

"I would like to see more on the automation side. There should be proper tools and support for automation in Tenable itself."

"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."

"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
