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

"Multi-cloud visibility saves time and makes things easier, as we can also have comparability to see what configuration differences have been made from cloud to cloud."

"Its excellent graphical interface makes the scanning process simple."

"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."

"Qualys TotalCloud provides unified vulnerability and threat assessment for IaaS and SaaS and a single prioritized view of risk, which helps reduce my workload by not having to combine multiple sources."

"Having everything in a single place to look for it and a single integration into ServiceNow has been the big transformation."

"TotalCloud offers a comprehensive suite of features, including EDR, XDR, and TrueRisk, providing a centralized platform for managing vulnerabilities and security risks."

"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."

"The scalability is good as well. I would rate it ten out of ten."

More Qualys TotalCloud pros

"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."

"Tanium is stable and it is also lightweight."

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

"The most valuable features of this solution are the consolidation of all historical data on device endpoints, security drivers, firmware, and Software version gaps."

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

"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 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."

"The solution's technical support is very responsive."

More Tanium pros

"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three."

"We can now deliver highly professional consulting using the product."

"The results are not that bad, but the key selling point is that it is an affordable tool set."

"The most valuable feature of Tenable Nessus is the dashboard, as they are convenient to use."

"Tenable Nessus is cheap and flexible."

"What I like most about Tenable Nessus is its vulnerability scanning feature."

"Its initial setup was simple and straightforward."

More Tenable Nessus pros

Cons

"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."

"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"

"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."

"The support process is inefficient due to the excessive number of replies required when submitting tickets."

"Customer support with Qualys TotalCloud needs a little improvement with the response times."

"The downside is only in container security, but it has not been a long time since they introduced these models."

"In TotalCloud, I would suggest improvements in policy checks to cater to various inventory types like VPCs, subnets, S3 buckets, or IAMs. 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."

More Qualys TotalCloud cons

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

"They could improve the UI."

"There are some bugs in the product. The tool needs to improve in the area of reporting."

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

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

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

"We had some issues with the solution's OS upgrade."

"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."

More Tanium cons

"Technically, it is an excellent and the best solution available in Libya. My only concern is related to its pricing. They are an emerging company in Libya, and they need to put in some effort to provide us with very good prices so that customers can go with the best solution. Chinese companies are getting into the market here, and they're providing very cheap solutions."

"We'd like to see more integration potential within the solution."

"I would like to have a management option after the network scanning."

"You can scale Nessus to the extent that you can afford it. You need to have a license for every device you scan. As long as you can afford the increased costs, you won't have a problem scaling it."

"Remediation needs improvement. They are providing a lot of superseded KBs as remediation."

"It would be nice for the professional module to include some of the reports available in the expert module."

"The pricing point has increased significantly in recent years. The product's pricing has roughly tripled within the last couple of years, making us reconsider renewing the license for the scanner."

"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."

"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."

"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."

"I would like to see better discounts."

"In general, it is extremely expensive."
