reviewer2859021 - PeerSpot reviewer
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.

Principal Security Architect at Nagarro
Has supported cloud-specific threat scanning but lacks coverage across hybrid and third-party workloads
They might launch support for third-party environments in the next version regarding the best features in Amazon Inspector from my perspective. The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning. It mostly covers specific native applications, and I think as per my understanding, it doesn't cover third-party environments or hybrid environments.
reviewer2872923 - PeerSpot reviewer
Vulnerability And Compliance Manager at a insurance company with 5,001-10,000 employees
Unified vulnerability view has improved risk-based decisions but reporting still needs work
One of the main issues with Nucleus Security is its lack of reporting capability. The user interface resembles an early 2000s application style, and although its speed is decent, it could be improved as more data is ingested. The overall appearance and feel need work, especially compared to modern applications from Rapid7, Qualys, and Tenable, which have more engaging user interfaces. The reporting capability is severely lacking; not being able to filter to granularity or have custom built queries is an annoyance that needs an overhaul. Additionally, there are bugs that have not been resolved, such as when you create a report and remove an asset, the asset still appears in the report despite not being present in the system anymore, leading to issues that need to be addressed quickly. Nucleus Security can become a difficult investment because I already have a vulnerability management solution, and I question where Nucleus Security fits with its licensing model. While I acknowledge automation has been described, it would be amazing to control the entire vulnerability management workflow from Nucleus Security without needing to log onto other systems. Having controls or actions that can be sent from the console down to the scanner for rescans would be beneficial. If Nucleus Security is going down this path, it should ensure that it becomes a one-stop shop for vulnerability management across multiple applications.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The scalability is good as well. I would rate it ten out of ten."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"The most valuable feature is the consolidated information that it provides from various platforms."
"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 best feature would be the ability to create policies. It is easy to control and update policies as required."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"TotalCloud has been excellent in providing us with immediate access to all the products and features we need, such as CSPM, TruRisk Insights, and compliance reports, including CIS and HIPAA."
"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."
"The most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"The scalability of the solution itself is unparalleled."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"The findings dashboards are neat and easy to understand, offering clear demarcations for different types of findings and detailed insights into specific vulnerabilities and their associated instances. It is not a place where everything is dumped together. It offers an easy-to-understand layout."
"The vulnerability discovery is valuable, and they also rank those vulnerabilities for you. So, you could rapidly attack some of the higher, severe vulnerabilities as they pop up, if they do pop up."
"Nucleus Security has fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."
"The best features Nucleus Security offers, in my opinion, are that it is really great in showcasing things and providing centralized vulnerability management."
"The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."
"Nucleus Security has impacted my organization positively by providing a single pane view of vulnerabilities from different connectors and enabling the automation of reporting and alerting on findings that are out of due date or out of SLA."
 

Cons

"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."
"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"The cost of Qualys TotalCloud is high and could be more competitive."
"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."
"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."
"The support is not up to the mark and seems to be overburdened."
"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."
"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"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 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."
"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"The other point is that the reporting features of Inspector need improvement. For example, I am in an organization with millions of CVEs, and getting an overview of all this is challenging."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"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."
"On a scale of one to ten, I would rate Nucleus Security overall a six."
"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."
"One of the main issues with Nucleus Security is its lack of reporting capability."
"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
 

Pricing and Cost Advice

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"TotalCloud's price is about right where I would expect it to be."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"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."
"Its price seems higher compared to other tools, but it is worth it. If they could adjust the pricing and make it comparable with other tools, that would be great."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"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's priced according to market standards for its services."
"The pricing is very transparent and clear."
"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."
