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.

Endpoint monitoring has strengthened incident response and provides rapid isolation and forensics
Tanium provides an endpoint which is isolated from the network and environment. We can easily search its logs and history and connect remotely directly to that particular device which has been isolated from the network. We can search for the history and logs, including audit logs and event logs. The complete activity of the user or owner of the device is visible to us. We can see the artifacts of particular USB transfers internally for official use. We can not only connect remotely but also see the device status and how many failures have occurred within the network so far. We can see the IP address, how many times it has changed its IP address, and how many times it was connected to VPN or external VPN or internal VPN and what has been searched while on VPN. We can block the IOCs or IP addresses as well. We can block domains, hashes, SHA values, SHA-256, SHA-1, SHA-5 and MD5. Although I am not completely involved in the automation team, we do have that team and I have worked in some CERT recently. Tanium is more useful while we are in the CERT because most of the times when we are on high alert, Tanium does play a main role for that particular incident or any high case. Tanium is a simple tool and we can easily integrate it to many devices and it is a mandatory tool to secure an endpoint. It is mandatory to give any RDP connection and the tool should be present in the particular device. It is completely mandatory and it is in the policy as well.

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 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 ability to identify cloud misconfigurations, prioritize security risks, and monitor cloud resources from a single platform is quite valuable."
"Having everything in a single place to look for it and a single integration into ServiceNow has been the big transformation."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"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."
"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"Qualys TotalCloud has positively impacted our organization by helping us save time and manage all assets and remediation, allowing us to achieve quarterly and half-yearly goals."
"TruRisk Insights is the most important innovation they've released this year."
"The product is granular and can build complex roles compared to other EDR vendors."
"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
"It's definitely not complex, it is pretty user-friendly and it's a solid tool enterprise to use."
"I find the inventory and compliance features of Tanium to be the most impressive."
"Tanium is stable and it is also lightweight."
"Tanium's most valuable feature is its instant discovery aspect."
"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."
"It allows me to prioritize efforts and utilize effective technical resources."
"With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device."
"Tenable integrates well with other solutions such as SIEM and batch management."
"The valuable feature for me is being able to ping the computers to do the automated scan and to come back and be able to see everything."
"Nessus is a very stable product, and it has been a pioneer and has been around for a long time."
"The solution is great for scanning servers."
"The best features of Tenable Nessus include its compatibility with other applications such as SIEM and other apps, allowing Tenable Nessus to work smoothly with them."
 

Cons

"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"In my opinion, the combination of detection and protection features in Qualys TotalCloud cannot protect but can only detect."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"One of the things that could be improved is the alerts. Qualys is a fantastic tool, especially with the TruRisk feature, but one challenge that most leaders face involves alert fatigue."
"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."
"I chose a rating of nine out of ten because there is a complex interface that sometimes overwhelms new engineers."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"There are downsides and drawbacks in Tanium, and there is room for improvement from my perspective."
"The main issues are the network connection because different customers have issues with their networks. It's difficult implementing this type of solution because the network is the main feature in the architecture for these types of solutions. Tanium could improve by creating some network optimization."
"The solution can give a lot of false positives."
"Any movement into a SaaS solution has challenges since the processes and data flows are not well defined. Hence, you need to build it at the same time."
"The problem or challenge is a pre-sales and go-to strategy for the SMB market delivered through a channel or model. It's very convoluted and vague, which leads to some confusion about the various types of modules, and the device-to-seat cost is extremely difficult to calculate."
"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."
"Tanium required local admin or root rights on Mac devices, which did not comply with our security policies. This made the solution less suitable for our restrictive environment."
"They have added a new Tenable Nessus Expert. That is their new product, which caters to the cloud and everything else. I am assuming that the new features and product enhancements are based on that tool set, but we haven't reviewed it yet."
"The professional version is not very scalable. It's not really scalable considering the number of assets and clients that I have."
"The inventory management function in this solution needs improvement."
"We have had some false positives in the past, which we hope can improve in the future."
"Lacks some penetration testing-related services."
"In terms of what could be improved, I would say its reporting portion."
"As a vulnerability management tool, the only aspect that is weak in Tenable Nessus is reporting; the rest is very strong."
"The professional version is not very scalable."
