A robust security operation that ensures achieving automation, stability, and scalability
There is room for improvement in some areas, and I would highlight three key aspects. Firstly, the Attack Surface Management (ASM) module could benefit from more contextual depth. Currently, it tends to provide a broad overview without enriched context, and there's room for enhancement in this regard. Secondly, further integration capabilities with various other software products that can seamlessly tie into Cortex XSIAM would be advantageous. This would enhance its versatility and interoperability within a broader ecosystem. Regarding performance, there's potential for optimization. When multiple tabs are open in Cortex XSIAM, it can experience slowdowns, leading to longer load times for web pages. It's worth noting that this isn't a severe issue, and it doesn't entail waiting for extended periods, but there is room for improvement in terms of performance optimization.

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.
