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

"I found the initial setup user-friendly."
"Its excellent graphical interface makes the scanning process simple."
"The vulnerability management feature is the one I like the most because it provides a clear picture of all vulnerabilities."
"Its dashboards are brilliant. It provides in-depth insights."
"In my opinion, this is the best tool."
"CSPM is currently the most used feature, and we are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs."
"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"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's most valuable feature is its instant discovery aspect."
"The interrogation piece was the most valuable feature because it was very detailed."
"Tanium is a very good product and I would rate it eight or nine out of ten."
"For inventory purposes, it's from one of the best things on the scene, as you can get live inventory."
"The insights we gain from our endpoints and the management capabilities that Tanium provides have been a boon to our operations and security."
"I find the inventory and compliance features of Tanium to be the most impressive."
"The security features are very valuable."
"So far, I am quite pleased with this product and don't have any complaints."
"It is a mature tool."
"With my experience, I would definitely recommend it."
"One thing that is important for us is that when the regulation agency is asking for something, we can send them reports from Nessus and they're very satisfied."
"If you are implementing it as part of an ongoing VA or retention operation, you should probably use Tenable."
"The solution is very good at vulnerability management."
"The scanning capabilities are most valuable when compared to Nessus."
"Tenable Nessus has helped us with better visibility of the current security posture of our infrastructure and helped us be proactive about remediating those findings."
 

Cons

"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"I would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."
"I chose a rating of nine out of ten because there is a complex interface that sometimes overwhelms new engineers."
"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"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."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"The most painful thing is the interface. It's a bit unclear sometimes."
"Our biggest issue with the solution is its lack of mobility."
"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."
"The performance could improve in future releases. We have had performance issues in specialized web environments, but overall I think the problems are less than 2% of the computer systems being used."
"Tanium’s scalability could be improved."
"Most of the time, agent-relative issues have to be more equipped with self-healing features. At times, the agent is there, but for some reason, it doesn't report a status. It gives certain problems that are obviously agent-based."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"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."
"The product must be more comprehensive."
"Tenable Nessus is not feasible for a large company."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"Nessus is not very good at identifying web application vulnerabilities, which means that we need to buy another product like Acunetix or EMC Networker to handle that part."
"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."
"Offer a more flexible strategic and high-level dashboards based on previous comments (minus technical and more business-oriented)."
"We'd like to see the solution embrace more user-friendliness."
"Based on my experience, the pricing for Tenable Nessus is somewhat higher, but customers still want to pay for it, so it remains acceptable."
