Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

Security posture has become visible and container risks are managed proactively
Regarding improvements for Calico Cloud, there is a need to build agentic security systems. I believe Calico Cloud is progressing towards this, and I believe they can enhance their teaching methods to facilitate adoption. Documentation needs continuous improvement. It is good and easy to read, but it can get better. Having a searchable summary feature, such as a chatbot, could help users quickly resolve issues without having to read extensive documentation. At the moment, I do not believe there are more improvements needed, but as mentioned earlier, there should be a focus on better documentation, possibly by embedding chatbot features that could respond to user prompts effectively.

Provides network mapping feature for visualizing container communication but complex setup
There is room for improvement in the setup process. All these tools come down to how you're integrating into your environment and having good knowledge of the tool. So that's the biggest problem with all these security tools – you gotta have knowledgeable people to build, integrate, and really flesh them out in your environment to make them work as they should.

Quotes from Members

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

Pros

"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"Its dashboards are brilliant. It provides in-depth insights."
"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"The best part I like is the on-demand scans."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"Once you have your vulnerabilities fixed and your patches pushed out using Qualys TotalCloud, then you are able to eliminate threats and cyber risk."
"We were able to realize its benefits within 24 to 48 hours."
"Calico Cloud has positively impacted my organization, especially on the security front, as it helped us anticipate security threats."
"Calico Cloud has positively impacted my organization by improving the security of deployed applications while having greater control and visibility over communication between the different microservices."
"Calico Cloud has had a positive impact on our organization by improving both our Kubernetes security posture and operational efficiency."
"The impact of Calico Cloud is that we were able to achieve a more secure understanding of our security posture, access our containers knowing full well that all policies set were followed through, and see visually how everything was interconnected, which has impacted our business positively."
"The benefit of working with the solution is the fact that it's very straightforward...It is a perfectly stable product since the details are very accurate."
"Scalability-wise, I rate the solution a nine out of ten."
"The technical support is good."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"One of the most valuable features I found was the ability of this solution to map the network and show you the communication between your containers and your different nodes."
"The most valuable feature of the solution is its monitoring feature."
"I am impressed with the tool's visibility."
"The most valuable feature is the ability to share resources."
 

Cons

"The vulnerability part is good, but the policy compliance module needs improvement because it involves a lot of manual work. Specifically, the remediation part of the controls requires enhancements."
"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"Their customer support needs improvement."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"They may not have all the features that their competitor Cilium has, and they are doing a portion of what Cilium does and a portion of what Istio does."
"Calico Cloud is a very good product with well-defined usage. I would appreciate seeing more improvement on real-time analysis capabilities."
"I think Calico Cloud could be improved by being a bit cheaper."
"The integration process of Calico Cloud with existing systems has its challenges."
"They're trying to convert it to the platform as a source. They are moving in the direction of Cloud Foundry so it can be easier for a developer to deploy it."
"The solution's visibility and vulnerability prevention should be improved."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"I do see that some features associated with the IAST part are not included in the tool, making it an area where improvements are required."
"Red Hat is somewhat expensive."
"The solution lacks features when compared to some of the competitors such as Prisma Cloud by Palo Alto Networks and has room for improvement."
"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."
"The solution's price could be better."
 

Pricing and Cost Advice

"The cost is high, but it meets our organizational needs."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"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."
"TotalCloud's price is about right where I would expect it to be."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"Qualys TotalCloud is expensive."
