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.

It helps you catch misconfigurations before they go into a production environment where they're harder to deal with

They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed. Asset visibility is also critical. While Tenable provides visibility into containers, it could be done much better. Compliance is one of the most crucial aspects of container security. It should be more customizable. For example, I would like a rating system where Tenable reports a risk score for each container based on user-defined metrics, such as severity, activity, or compliance.

Quotes from Members

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

Pros

"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."

"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."

"The log monitor is the most valuable feature."

"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."

"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."

"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."

"From a container-based standpoint, it offers excellent scalability to its users...I would tell those planning to use the solution that, from a container standpoint, it's excellent."

More Sysdig Secure pros

"Tenable.io detects misconfiguration when you deploy a Docker or Kubernetes container. It's much better to remedy these issues during deployment instead of waiting until the container is already in the production environment."

"It helps us secure our applications from the build phase and identify the weaknesses from scratch."

"Nessus scanner is very effective for internal penetration testing."

"The tool's most valuable feature is scanning, reporting, and troubleshooting."

"Currently, I haven't implemented the solution due to its deprecation by the site. However, I can highlight some benefits of Tenable Cloud Security, a cybersecurity solution with various features for scanning vulnerabilities in both cloud environments and on-premises container security."

"The solution shows you the exploitable vulnerabilities and helps you prioritize."

"The strong security provided by the product in the container environment is its most valuable feature."

"It is a scalable solution. Scalability-wise, it is a good solution."

Cons

"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."

"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."

"The solution needs to improve overall from a CSPM standpoint since they can't compete with Wiz or Orca."

"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'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."

"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."

"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."

"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."

More Sysdig Secure cons

"I feel that in certain areas this product has false positives which the company should work on. They should also try to include business logic vulnerabilities in the scanner testing. Finally, the vulnerability assessment feature should be increased to other hardware devices, apart from firewalls."

"The support is tricky to reach, so we would like better-oriented technical support enabled."

"Tenable.io Container Security should improve integration modules. It should also improve stability."

"I believe integration plays a crucial role for Tenable, particularly in terms of connecting with other products and various container solutions like Docker or Kubernetes. It seems that in future updates, enhanced integration is something I would appreciate. Currently, there is integration with Docker, but when it comes to Kubernetes or other container solutions, it appears to be a challenge, especially with on-prem scanners."

"The solution’s pricing could be improved."

"They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed."

"The stability and setup phase of the product are areas with shortcomings where improvements are needed."

"The initial setup is highly complex."

Pricing and Cost Advice

"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."

"It is quite costly compared to other tools."

"I rate the tool's pricing a three out of ten."

"The product does not operate on a pay-per-license model."

"The solution's pricing is neither cheap nor very expensive."

"I rate the product’s pricing a six out of ten."

"It's best to be an institutional buyer and directly contact the sales team as they can provide over-the-top discounts for bulk orders."
