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 Red Hat Advanced Cluster Security for Kubernetes pros

"The proactiveness of the support has been fantastic. Every time we mention something in a meeting that we're trying to do, he proactively takes that as an investigation topic and looks into it. He'll provide the solution even though we might not have asked him to investigate it."

"We appreciate this feature, especially when combined with CD monitoring. The implementation of requested features has been remarkable, such as scanning for compliance in CRM processes for the US government. We heavily rely on this feature to assess compliance with federal requirements."

"I have not seen any stability issues so far."

"The most valuable feature is the level of support that we get. Our solutions or customer success representative is very valuable. I see them as an extension of our security team."

"The tool has the capability to conduct scans initially. It can perform scans on your virtual machines, physical machines, containers, and container images. A standout feature is its ability to scan offline container images stored in your container registry. Additionally, it can scan runtime images in your cluster or on your host machine. This allows for the detection of vulnerabilities in running containers, including loaded libraries. Notably, the tool can identify which library vulnerabilities are already present in your system. An added advantage is its capacity to take action beyond threat detection. It has the ability to block access and respond to encountered threats."

"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."

"I see Sysdig as the most comprehensive solution in comparison to its competitors."

"The log monitor is the most valuable feature."

More Sysdig Secure pros

Cons

"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."

"Red Hat is somewhat expensive."

"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."

"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."

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

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

"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."

More Red Hat Advanced Cluster Security for Kubernetes cons

"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."

"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."

"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."

"Banks and financial institutions cannot use Sysdig Secure because it doesn't sell SaaS-hosted versions for under two hundred working nodes."

"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."

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

"The dashboard could be more simple and show the more important issues that are detected first. We'd like to be able to set it up so more important issues show up more prominently in the dashboard."

Pricing and Cost Advice

"It's a costly solution"

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

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

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

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

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

"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."

"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."

"It is quite costly compared to other tools."

"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."
