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.

Stable product with an ability to build complex roles
We use Tanium as an EDR solution for managing end-user devices and servers The product is granular and can build complex roles compared to other EDR vendors. Tanium's dashboard UI could be similar to CrowdStrike. We have been using Tanium for two and a half years. The product is stable. I rate…

Quotes from Members

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

Pros

"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"I like the fact that you can create patching campaigns depending on the area of your network that you want to address first. I like the ability it has to make several campaigns that work in parallel."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"The most valuable features of this solution are the consolidation of all historical data on device endpoints, security drivers, firmware, and Software version gaps."
"For incident response tasks, all these tasks can get done in minutes with minimal disruption to the end-user."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"The product is granular and can build complex roles compared to other EDR vendors."
"Tanium’s linear-chain architecture is valuable."
 

Cons

"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."
"The solution lacks mobility."
"It is not really additional functions, or the features that are needed, rather the complexity would be reduced based on the number of modules required to put together a comprehensive operational security and risk compliance model."
"They could improve the UI."
"The main issues are the network connection because different customers have issues with their networks. It's difficult implementing this type of solution because the network is the main feature in the architecture for these types of solutions. Tanium could improve by creating some network optimization."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"The reporting could be improved."
"Tanium required local admin or root rights on Mac devices, which did not comply with our security policies. This made the solution less suitable for our restrictive environment."
"The most painful thing is the interface. It's a bit unclear sometimes."
 

Pricing and Cost Advice

"It’s a single license platform."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"The solution is expensive but it's a good investment."
"It's an expensive solution. It would be nice if the cost were lower."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"There is an annual license required to use this solution."
"The solution offers value for money."
"It is higher than some competitors in the market."
