Senior Process Expert at A.P. Moller - Maersk
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 normal protection was really effective, and we detected situations that if we didn't have Cortex XDR by Palo Alto Networks, it's highly likely that we would have been affected, but it protected the infrastructure."
"The information the dashboard provides is very clear."
"The one feature of Palo Alto Networks Traps that our organization finds most valuable is the App ID service."
"What I like about Cortex XDR by Palo Alto Networks is that it is a comprehensive solution that contains everything the organization may need when using endpoints."
"Has great threat detection capabilities."
"Monitoring is most valuable."
"The most valuable for us is the correlation feature."
"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."
"Whether our endpoints are running on Windows, Mac, Linux, or any flavor of operating systems, and even mobile devices, we can have a central dashboard through which we can do complete user management and policy management. We can have a complete security posture organization-wise, department-wise, or business-wise."
"The ability to quickly and easily identify threats on our machines is valuable. The fact that it protects the environment as a whole is also valuable. They have the ability to identify network nodes, and they have Ranger as a component of the solution that allows us to see the whole picture. We can see on what we have SentinelOne and on what we do not."
"We collect a lot of telemetry from Singularity Complete."
"We have had very few false positives or false negatives, which allows our analysts to focus on their work instead of dealing with noise."
"One of the features that convinced us to adopt SentinelOne was that the solution can recognize and respond to attacks with or without a network connection. That is very important."
"Singularity has the same features as other antivirus products, but it provides an added layer of security and vulnerability protection. It's also light on resources. Singularity doesn't use a lot of CPU or memory."
"I have found the most valuable feature to be the rapid threat detection."
"SentinelOne Singularity Complete has a valuable feature that allows us to install the agent on every endpoint and extract all asset information for reporting purposes in our live inventory."
"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

"They are charging for Network Traffic Analyzer (NTA) services, so if the per GB data could be provided at a certain level free of cost or at the same cost which the customer is taking for the entire bundle, that would be better."
"The solution should offer more dashboards and they should be better customized."
"Data privacy is a matter of concern. You have to be careful with data privacy, it can be sensitive and Cortex can have most of your access."
"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."
"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."
"It automatically detects security issues. It should be able to protect our network devices while operating autonomously."
"In terms of areas of improvement, we have not completed our review of the product. We're also looking at other products. So, it's a little bit hard to tell what could be different because we have not completed the review of this product, but based on our experience so far, its implementation is quite complex."
"Cortex XDR by Palo Alto Networks is a very good product, but financially, it is very expensive, so the company should look into that area."
"SentinelOne can improve by having better integration with Active Directory."
"From the data security point of view, SentinelOne Singularity Complete is not good."
"Some reports could be better."
"The endpoint firewall capability is fairly primitive and basic."
"The filtering features of the application management console could be improved."
"If there is a vulnerability that we know about, I search for that vulnerability—for example, Adobe. There are different versions of Adobe, but I'm not able to compile them into one report. I have to create separate reports for those versions."
"SentinelOne's customer support is sluggish and frequently fails to deliver sufficient assistance."
"With respect to product patches, it should have the ability to patch directly from SentinelOne, rather than be presented with a list and have to do it separately."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"This is an expensive solution."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"Very costly product."
"It's about $55 per license on a yearly basis."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."
"The pricing is very reasonable."
"While the cost of SentinelOne Singularity Complete might seem high at first glance, it's important to consider the value it offers."
"I believe that the current pricing and licensing structure is fair."
"The pricing is on the higher end, making it less suitable for small or medium-sized businesses and perhaps not the ideal fit for the public sector where budget constraints may be more pronounced."
"The cost of endpoint protection is fairly reasonable."
"The price is fair for what we are getting."
"The price for it is very competitive compared to other Next Gen EPP."
"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."
"It’s a single license platform."
