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.

Offers easy management and container connection with HTTPS, but the support needs to improve

I have experience with the solution's setup in Rio de Janeiro, Brazil and our company has assisted in the development of a cluster in a research department, but we didn't start from scratch because we have IT professionals who have installed Kubernetes across 12 nodes of a cluster and a new environment can be created for a new platform. I also had another setup experience of Red Hat Advanced Cluster Security for Kubernetes in Portugal where I had to implement the solution in a cluster of 22 computer servers, which was completed with assistance from the IT department of the company. The initial setup process of the solution can be considered as difficult. The setup process involves using the permissions, subnets and range of IPs, which makes it complex. Deploying Red Hat Advanced Cluster Security for Kubernetes takes around eight to ten hours for new clusters. The solution's deployment can be divided into three parts. The first part involves OpenStack, where the cluster's resources need to be identified. The second part involves virtualizing assets and identifying other physical assets, for which OpenStack, Kubernetes, or OpenShift are used. The third part of the deployment involves dividing the networks into subnetworks and implementing automation to deploy the microservices using Helm. The number of professionals required for the solution's deployment depends upon the presence of automated scripts. Ideally, two or three professionals are required to set up Red Hat Advanced Cluster Security for Kubernetes.

Runtime threat detection has improved and security teams prioritize real Kubernetes risks

The best feature Sysdig Secure offers is threat detection. The threat detection feature on Sysdig Secure stands out compared to other solutions I have seen or used because Sysdig sees the actual behavior inside the container or kernel and correlates it with Kubernetes infrastructure, which makes detection both earlier and more precise in a cloud-native environment. Sysdig Secure has positively impacted our organization by improving visibility into our Kubernetes environment and focusing on real risk, which has reduced alert noise, improved threat detection at runtime, and made vulnerability management more efficient by prioritizing issues that actually affect running workloads.

More Sysdig Secure pros

Cons

"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."

"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."

"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."

"The response part of the Cloud Detection and Response (CDR) module can be improved."

"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."

"The cost of Qualys TotalCloud is high and could be more competitive."

"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."

"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."

More Qualys TotalCloud cons

"The solution's visibility and vulnerability prevention should be improved."

"Red Hat is somewhat expensive."

"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 lacks features when compared to some of the competitors such as Prisma Cloud by Palo Alto Networks and has room for improvement."

"The tool's command line and configuration are hard for us to understand and make deployment complex. It should also include zero trust, access control features and database connectivity."

"The support and specifications need to be up to date for the cluster technologies"

"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."

"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."

More Red Hat Advanced Cluster Security for Kubernetes cons

"Sysdig's biggest weakness is dashboarding and reporting. You have access to the data and can get everything you need, but we need the ability to summarize the information quickly in a format that senior leaders can understand. We report to the executive level and global board. I need to roll all that in-depth information into a quick summary, and their maturity level isn't there. I'm seeing that on the future road map, but it isn't there now."

"Sysdig Secure works well for us, but there are a few areas for improvement, such as the alerting and notification system being more flexible for complex workflows, and some dashboard and reporting features could be more customizable to match specific team needs."

"They should make it specific with a couple of features only."

"Perhaps, it could support more custom implementations, as our company utilizes custom implementations rather than standard ones. Configuring it requires a deep understanding and adjustment to our specific needs, which took some time. Other than that, I'm unsure about potential improvements. We were considering the possibility of compartmentalizing their tools. Currently, in Sysdig Secure, they bundle multiple features, and we are unable to use them individually. For instance, if we only need compliance scanning, we have to deploy the entire secure package. This is because of the way their agent functions, but I can't delve into more details."

"Reporting can definitely be better. Live dashboards should be configurable for a longer period of time rather than 30 days. Being able to go back in time to compare six months ago to today would be valuable."

"There was a security concern related to a specific feature. While the feature itself was promising, it posed a challenge. The situation revolved around code scanning. If your source code is hosted within your own premises, say on Bitbucket, you naturally wouldn't want your code to be accessible to external parties beyond your company. Keeping your code base private is a standard practice. However, in the case of code scanning using Sysdig Secure, they copy your code to their SaaS platform. This posed an issue for us. When we inquired about this, their response acknowledged the concern. In an upcoming release, they plan to enable code scanning within your on-premises environment through the assistance of an agent. This change is already in progress. While this tool stands out compared to existing solutions in the market, it's important to note that there are still some limitations to consider. Another drawback we encountered relates to our expertise with Kubernetes. The tool can monitor Kubernetes audit logs, triggering alerts and notifications. However, it falls short in terms of taking direct action based on these alerts. There are different methods of event capture, including through system labels and system calls, as well as via Kubernetes audit events. Notably, at the system level, Sysdig Secure can both detect and respond to events, allowing actions like blocking and warning. This proactive approach is effective at the system call level. However, when it comes to monitoring Kubernetes audit events, Sysdig Secure can only notify without being able to execute any further actions. It can't block access or containers. The vendor likened their role to that of a monitoring camera, observing events and sending notifications without the capacity to intervene. This limitation applies to Kubernetes audit events. Given that everything operates within our system, there is a workaround available: configuring system-level policies to block containers as necessary."

"I give it an eight because of the bugs, specifically the fix version bug where sometimes there is no fix version shown, and I wish Sysdig Secure would create a customizable UI that orders features by importance to enhance user experience."

"Sysdig Secure needs to scale more for complete cloud-native coverage."

More Sysdig Secure cons

Pricing and Cost Advice

"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."

"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."

"Qualys TotalCloud is expensive."

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."

"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."

"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."

"I am not sure about the pricing. From what I understand, it is a bit on the higher side, but I do not have the exact numbers."

More Qualys TotalCloud pricing and cost advice

"The price of Red Hat Advanced Cluster Security for Kubernetes is better than Palo Alto Prisma."

"It's a costly solution"

"The pricing model is moderate, meaning it is not very expensive."

"Red Hat offers two pricing options for their solution: a separate price, and a bundled price under the OpenShift Platform Plus."

"We purchase a yearly basis license for the solution."

"It is quite costly compared to other tools."

"The solution's pricing depends on the agents...In short, the price depends on the environment of its user."

"In comparison to other cloud solutions, it's reasonably priced. However, when compared to in-house built open-source projects, it might be considered somewhat costly. The cost depends on whether someone sees the support provided by Sysdig as an advantage or if it's deemed unnecessary. Personally, I find the support to be excellent and consider it a good value."

"I am always going to say that it could be a little bit cheaper. I do feel that it is a little bit on the expensive side."

"Sysdig is competitive. The quality matches the pricing. Obviously, everyone wants things to be cheaper, but if you're realistic, you acknowledge that quality service comes with a price. Sysdig is the gold standard for Kubernetes, and I wouldn't choose anything else. We live in Kubernetes. Everything is containerized, so that means a lot to us, and we're willing to make an investment."
