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.

Automated insights streamline data security assessment
For Amazon Inspector, we have many EC2 or virtual machines deployed inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages. As we progress with time, this package needs to be updated for security enhancement, which requires us to uninstall the package, install the new version, and then we should be fine. However, the challenge comes with how to scan all our EC2 instances for security vulnerabilities, which is currently managed by Amazon Inspector. Amazon Inspector can scan EC2 instances or ECR, which is the ECR registry where we can save artifacts Docker images. Amazon Inspector can also scan Docker images uploaded to ECR for Elastic Registry service, and it can scan databases and S3 based on the latest updates. I noticed this from a couple of months ago, and it provides huge benefits for security. Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are causing security concerns. Amazon Inspector can list these security concerns and offer guidance on how we can remediate it by updating the package to a specific upper version or something similar.

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 would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"In my opinion, this is the best tool."
"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."
"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"The vulnerability management feature is the one I like the most because it provides a clear picture of all vulnerabilities."
"TotalCloud provides the easiest and the best approach for cloud infrastructure management."
"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."
"The automated vulnerability detection aspect is most valuable."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"My experience with AWS technical support is very good, I didn't face any specific challenges, and even the documentation of AWS is good for both Microsoft, which is Azure, and AWS."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"The scalability of the solution itself is unparalleled."
"It is scanning the whole repository for any sort of vulnerabilities, so it allows us to be more confident in our DevSecOps and not put a lot of folks or attention to it."
"The integration of Amazon Inspector with other AWS services has enhanced our security. Security Hub is a major asset because it allows us to centralize data from various AWS services. We can integrate third-party tools as well. It is just a single-click option."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."
"The solution is easy to understand for users because instructions are included on the platform."
"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 gives me a good preview of vulnerabilities and good suggestions for remediation. It's easy to find a description of a given vulnerability and solutions for it."
"Tenable Nessus is very easy to support and manage and this is why I have not needed to contact support."
"Tenable Nessus streamlines the process of scanning for our organization."
"With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device."
 

Cons

"The response part of the Cloud Detection and Response (CDR) module can be improved."
"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"There is room for improvement in the support."
"There is room for improvement in vulnerability scanning, particularly for PaaS environments. Currently, Qualys does not have full access to these instances, which limits its effectiveness."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"It has a limited scope. So, AWS Inspector primarily focuses on the security of the EC2 instance. So, if your architecture includes other AWS services, then you may need to use additional tools for your comprehensive security assessment. So that is one con. Another is, like, we have a dependency on agents."
"One area for improvement in Amazon Inspector is the automation aspect."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"One major area for improvement is remediation. My team works on remediating findings over time, likely using available patches. However, easier integration with Amazon's patching services would be very helpful."
"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"There isn't too much to improve right now. Scanning on demand or as a part of the pipeline versus a post pipeline solution would be good, but it is not a deal breaker by any means."
"The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."
"Consumes more system resources when it's running."
"From my point of view the solution basically is not for the big enterprise."
"They should try to create an all-in-one solution."
"They should improve the I/O reporting and the customized spreadsheet export feature."
"The professional version is not very scalable."
"We operate in small and medium enterprises and for them, Nessus is becoming expensive."
"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
 

Pricing and Cost Advice

"Qualys TotalCloud offers cost-effective licensing flexibility."
"The cost is high, but it meets our organizational needs."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"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."
"The lowest cost would be around $10 for a few small accounts, however, for thousands of accounts, it could be around $5000 to $6000 dollars per month."
"It is scaled as you go. There are probably a certain number of scans per month, and there are tiers. If you're under a certain tier, it is free. The second level is pennies, and then all the way up to like a million. So, it has a tiered pricing program. They're pretty good with your initial scanning, and there is room to scale based on being affordable, but it is fairly cheap. There are no additional costs. They pretty much think about it as a pay-per-scan type model."
"It's priced according to market standards for its services."
"The pricing is very transparent and clear."
"The solution is expensive."
"The price of the solution is reasonable."
"The solution has free options."
"The price of Tenable Nessus could improve, it is expensive."
"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."
"I would like to see better discounts."
"We pay approximately $2,500 on a yearly basis."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
