Tells us about vulnerabilities as well as their impact and helps to focus on real issues

Looking at all the different pieces, it has got everything we need. Some of the pieces we do not even use. For example, we do not have Kubernetes Security. We are not running any K8 clusters, so it is good for us. Overall, we find the solution to be fantastic. There can be additional education components. This may not be truly fair to them because of what the product is going for, but it would be great to see additional education for compliance. It is not a criticism of the tool per se, but anything to help non-development resources understand some of the complexities of the cloud is always appreciated. Any additional educational resources are always helpful for security teams, especially those without a development background.

Boosts security by automatically blocking applications or activities, but query responses have been slower recently

For the past six months, we have been facing some issues. Because it is a cloud-based infrastructure, it has been getting slower. There are no bugs because they release updates continuously. We highly appreciate that, but during hunting or running a query on different logs, the time frame has increased in the past six months. It takes longer to give us the results. Another issue is the lack of proper documentation. During investigations, there is no proper documentation available. This is a problem because many people are saying there should be proper documentation explaining what CrowdStrike captures from the machine and the meaning of it.

Gives real-time visibility and helps to articulate constantly-changing landscape

The main benefit for me personally is being able to articulate the ever-growing, dynamic, and constantly changing landscape. Just today, in a management leadership call, I was able to demonstrate that although we are solving a lot of these vulnerabilities, we are picking up new vulnerabilities each and every day. It allows me to articulate the importance of information security with actual real-time data. Sysdig's runtime insights help us detect and respond to threats that are happening in real-time. We can look at Sysdig dashboards or run reports to see precisely what happens in our runtime environment. A good use case of this was that when zero-day vulnerabilities came out, we could scan our environment to see if the vulnerabilities apply to any of our production workloads. Sysdig Secure helps us prioritize issues and distribute work. We are a small company, so we do not have multiple security or dev teams. We have two or three guys on my team. Having the ability to focus on critical vulnerabilities is crucial. It does not make sense to prioritize low-level threats when we have limited time. We do not use live threat investigation features as much as we would like because of different priorities, but it is something that we do use. Over time, it shows us whether we are putting the right effort into resolving issues. For example, when we look at the dashboard scene over a 30-day period, we can see whether the critical vulnerabilities are increasing or decreasing. It lets us know whether we are on the right track. We are currently using agentless scanning. Deploying it onto our cluster has enabled us to get full visibility into what is running on our cluster. Sysdig provides us with the contextual awareness we need to create an immediate incident response strategy. It provides links to the threat and explains the threat and the resolution possible. It equips us with the right information to make a decision on whether to address the threat immediately or take a risk in terms of deploying remediation. Sysdig has not enabled us to reduce the number of security tools we use. We were not using anything before Sysdig, and after choosing Sysdig, we did not have a need to look at anything else. Sysdig has not helped reduce external SOC costs. We are a very small business, so we do not have the budget for an external SOC. However, it has definitely alleviated the pressure to look for one and to source an external SOC. We have a project history to look at a virtual SOC and leverage tools that we do have, and Sysdig is a part of that. There is definitely a saving there because we have not had the need to go out and look for an external SOC. Sysdig has helped reduce the percentage of workloads that have security exposures that put the organization at risk. It has reduced the workload, mainly from an understanding of where we can assign work to cover the most ground in terms of resolving vulnerabilities.

Quotes from Members

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

Pros

"We noted immediate benefits from using the solution."

"The UI is very good."

"The multi-cloud support is valuable. They are expanding to different clouds. It is not restricted to only AWS. It allows us to have different clouds on one platform."

"The most valuable feature is the notification system, providing real-time alerts and comparisons crucial for maintaining security."

"It saves time, makes your environment more secure, and improves compliance. PingSafe helps with audits, ensuring that you are following best practices for cloud security. You don't need to be an expert to use it and improve your security."

More SentinelOne Singularity Cloud Security pros

"It provides alerts on suspicious command executions, helping us safeguard our systems."

"We like the solution's management and monitoring tools for our network. We use it to monitor our network between workstations and outside our organization. The AI provides useful visualizations of our network on a dashboard."

"The most valuable features are the real-time response, which allows me to log into a machine to pull files and check signatures for malicious activities, and the ability to restrict USB block storage usage on endpoints by policy."

"It is fully cloud-based, so we don't need to invest in third-party agents repeatedly."

"CrowdStrike utilizes signatureless technology, eliminating the need for regular signature updates on endpoint systems."

"The most valuable features of CrowdStrike Falcon include its automation capabilities, efficacy, and lower risk."

"I have contacted customer service, and they are fast."

"The most valuable feature of Falcon Cloud Security is its comprehensive threat-hunting ability."

More CrowdStrike Falcon Cloud Security pros

"Sysdig Secure has many strong foundational features like compliance and benchmark, security, network access management, and vulnerability management."

"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."

"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 log monitor is the most valuable feature."

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

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

"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 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."

More Sysdig Secure pros

Cons

"I would prefer to see SentinelOne Singularity Cloud Security develop into a single pane of glass for ASPM and CSPM."

"PingSafe filtering has some areas that cause problems, and to achieve single sign-on functionality, a break-glass feature, which is currently unavailable, is necessary."

"I would like PingSafe's detections to be openly available online instead of only accessible through their portal. Other tools have detections that are openly available without going through the tool."

"In the Analytics section, there is a tab for showing the severity of open issues by day. There are three options: by week, by month, and for more than thirty days. However, despite being aware of many issues open for more than thirty days, it shows no data available."

"For vulnerabilities, they are showing CVE ID. The naming convention should be better so that it indicates the container where a vulnerability is present. Currently, they are only showing CVE ID, but the same CVE ID might be present in multiple containers. We would like to have the container name so that we can easily fix the issue."

"They can work on policies based on different compliance standards."

"While PingSafe offers real-time response, there is room for improvement in alert accuracy."

"After closing an alert in Cloud Native Security, it still shows as unresolved."

More SentinelOne Singularity Cloud Security cons

"There were some integration issues with this product."

"The CrowdStrike partner portal documentation could be improved to provide proper instructions for integrating their products."

"It would be more convenient if there was an easier way to install CrowdStrike, perhaps through better integration with Active Directory."

"Customers would benefit it CrowdStrike adopted some of SentinelOne's technologies."

"It gets the work done, but the main problem with the solution is that if you remediate anything, it takes 45 days for you to get any of the features displayed on the dashboard. This is the real weakness of CrowdStrike. Their customer support is also not ready to help with it. If you remediate any cloud vulnerability that they are giving you, such as removing a host from your organization, it takes around 45 days for them to remove it from their console."

"One area for improvement in Falcon Cloud Security is the support portal."

"For the past six months, we have been facing some issues. Because it is a cloud-based infrastructure, it has been getting slower."

"The tool could give us more templates so that people who are not updated with the platform can easily get acquainted with how to secure and utilize the product more."

More CrowdStrike Falcon Cloud Security 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."

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

"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."

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

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

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

More Sysdig Secure cons

Pricing and Cost Advice

"While SentinelOne Singularity Cloud Security offers robust protection, its high cost may be prohibitive for small and medium-sized businesses."

"It is a little expensive. I would rate it a four out of ten for pricing."

"It is cost-effective compared to other solutions in the market."

"SentinelOne offers excellent pricing and licensing options."

"It's a fair price for what you get. We are happy with the price as it stands."

"I would rate the cost a seven out of ten with ten being the most costly."

"Its pricing was a little less than other providers."

"It was reasonable pricing for me."

More SentinelOne Singularity Cloud Security pricing and cost advice

"The pricing is reasonable, neither overly expensive nor excessively cheap, making it competitive compared to other market options."

"It's an expensive product"

"Its price is moderate."

"CrowdStrike Falcon Cloud Security is very expensive for us. Last month, we had a big issue that took much time and money to resolve. It slowed down our business and required our management team to get involved. We had a problem similar to the "Blue Screen of Death" issue many US companies faced. This incident used up many of our IT resources in just a few months. That's why we're looking for a replacement tool now."

"It is expensive, but it adds value."

"It's an expensive package but does what it says it will do."

"CrowdStrike Falcon Cloud Security is pricy."

"The pricing is fair for what you get. I'd rate them a solid nine out of ten in terms of pricing."

More CrowdStrike Falcon Cloud Security pricing and cost advice

"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."

"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 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."

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