Gained full visibility and streamlined threat detection through behavior-based insights and AI integration
Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth. We have fine-tuned our security policies and allowed different levels of policies to get rid of those false positives. Currently, we are getting a fairly good amount of incidents that are not false positives or benign, but actionable items. The process is streamlined. In the initial days, the operations used to get involved in a lot of benign and other activities, but now the process is streamlined. We are leveraging the auto-detection and remediation plans. The operations teams are now more involved in other business roles as well, not just looking into the logs and fetching out what's happening there. They have fixed a lot of things. Initially, they didn't have IAC code drift detection, cloud posture management, or security posture management, but they have those now. They purchased different vendors and did a merger with that. They have now Prisma Cloud that gets integrated and now they are working with Cortex Cloud. Everything that was negative has now been addressed, and the product altogether looks to be in a very better and mature shape now. Currently, it's more or less detecting the workloads with AI-based best practices. Since most organizations are consuming AI agents and other things, we are looking forward to seeing what other feature enhancements Palo Alto can support in that.

Automation has reduced alerts and freed the soc team to focus on faster incident response
Regarding mean time to respond, the improvements I see with SentinelOne Singularity Complete are that genuine files also get alerts. We are getting false positives, but we are also getting genuine true positive alerts. The improvement will be deep visibility because as I am using Splunk as a SIEM, I compare deep visibility with Splunk, but deep visibility has limited access with only a 14-day policy to retain logs. The improvement will be in overall policy management. The third point will be the complexity of policies. If we want some endpoints to use only USB or if we need to block USB on some points, the policy management is very complex. The fourth point will be that Mac OS and Linux don't have the rollback policy; that policy is only for Windows. These four points are improvements if SentinelOne Singularity Complete can address them. Data privacy and security when utilizing Purple AI is crucial for SentinelOne Singularity Complete, and SentinelOne Singularity Complete lacks in data security. Data security is very important in this world. In my organization, if we deploy SentinelOne Singularity Complete and we have integrated all the firewalls, all devices, and AWS devices to SentinelOne Singularity Complete, logs will be forwarded to SentinelOne Singularity Complete through SentinelOne Singularity Complete. However, SentinelOne Singularity Complete doesn't have data security solutions such as Forcepoint DLP or 48 layer; SentinelOne Singularity Complete doesn't have that DLP solution. From the data security point of view, SentinelOne Singularity Complete is not good.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"The most valuable feature of Cortex XDR by Palo Alto Networks is the low consumption of system resources. The solution uses a lot of AI and machine learning."
"Provides behavior-based detection which offers many benefits over signature-based detection."
"The dashboard is customizable."
"We've had a significant increase in blocking with a decrease in false positives, because it's looking at how the files work, not just a list of files that it's been told to look for."
"We have a complete overview of all our PCs and it's very easy to handle and to use the interface. It has a lot of benefits for us."
"The tool is easy to use."
"The positive impacts I see from Cortex XDR by Palo Alto Networks include a complete 360-degree view of our security posture altogether, being a uniform platform where we are ingesting logs from multiple resources."
"But overall, when we speak about security and protection, they are one of the top providers."
"The product can scale as needed."
"SentinelOne supports both Linux and macOS."
"In 18 months in with SentinelOne, we've seen the same lack of drama, with no endpoints compromised to the degree that it has negatively impacted our network."
"The way SentinelOne works and the way it is set up, I haven't been more impressed by any other product."
"Offers good protection against ransomware."
"The most valuable features of SentinelOne Singularity Complete are machine learning because it saves us time, device control for data privacy, and the token."
"We have a preference for their receptor. It's good at finding many EFC files. EFC files could have a virus."
"SentinelOne is a much better solution with better value and a lower cost than the McAfee ePO."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"The encryption is not up to the mark."
"Being able to filter the events to see those that are related to the actual alert would save time spent by the engineer."
"The technical support is not very good. I find the process difficult."
"Cortex does not offer an on-premises solution. However, some customers would prefer not to be on the cloud. It would be ideal if it could offer something on-prem as well."
"It should support more mobile operating systems. That is one of the cons of their infrastructure right now."
"While using Cortex, I noticed some aspects that could be improved, such as increasing the synchronization speed between XDR and Xnor."
"Currently, if you use Palo Alto endpoint protection as the only solution it's very complicated to remove pre-existing threats."
"Currently, we are monitoring all USB drives and ports but we would like to improve our device control capabilities."
"From the data security point of view, SentinelOne Singularity Complete is not good."
"Sometimes, SentinelOne Singularity Complete takes time to reflect on some machines, which could be due to poor network connectivity."
"One disadvantage of SentinelOne Singularity Complete is that the agent doesn't auto-update, and my company found it more complicated than usual to get the agent updated and keep it updated."
"The only thing that prevented the attack from succeeding was a free version of Malwarebytes that was running on the session, which effectively protected against it. The MSP confirmed that SentinelOne failed to detect the threat."
"The way Singularity Complete handles blocking external mass storage is annoying because it is so difficult to unblock single endpoints."
"The grouping feature needs improvement."
"I would like to see something a little more sophisticated than simply being able to mark a false positive as safe or there's usually just one or two options in certain areas and they're a little rudimentary at this stage."
"I would appreciate it if they would consider providing a comprehensive vulnerability assessment report that goes beyond just application vulnerabilities."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"The solution is expensive. It's pricing is on a yearly-basis."
"I did PoCs on products called Cylance and CrowdStrike. Although, I consider these products and they were also good, when it come to cost and budgetary factors, Traps has been proven to be better than the other two products. It is quite cost-effective and delivers all the entire solution which we require."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"The price of the product is not very economical."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"It is "expensive" and flexible."
"You have to look at the kinds of problems you can end up with and the fact that you want security against them, and then SentinelOne is not expensive."
"The pricing level for this service and application was very interesting for us. I don't know exactly what the price was, but apparently it was a big surprise that the SOC was also included in our pricing model."
"SentinelOne Singularity Complete's price point is excessive compared to the functionality it provides."
"We buy the licensing in bulk. From a pricing standpoint, because we buy in bulk, we get very good pricing. Based on its functionality and capabilities, it is well worth the price. I do not think it is at all expensive based on what you get in the solution. We use the complete up to the core. Our pricing is probably a little bit more than somebody who is on the core. In general, it is well worth what you get for the price you pay."
"I don't deal with the cost side of things, but the licensing, as far as endpoints go, is a pretty straightforward and simple process."
"The pricing is very fair for the solution they provide."
"I find the licensing cost for SentinelOne Singularity Complete fair."
"It is very affordable and easy to license, and it allows us to onboard new analysts quickly, with a turnaround time of one day at most."
"It’s a single license platform."
