Room For Improvement

Cortex XDR requires enhancements in UI, integration, reporting, and pricing, while addressing false positives and improving automation and mobile support.
Kaspersky EDR Optimum requires better firewall integration, UI improvements, simplified setup, enhanced support, and unified tool management.
Microsoft Defender for Business needs improved reporting, threat protection, support, and integration, with attention to pricing and update communication.
Improving reporting and dashboard customization, along with the addition of real-time and exportable reports, would help SOC teams greatly.

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.

Continuous protection has improved automated threat response and reporting for our endpoints
We did work with one of our clients who required mobile security solutions. In my opinion, Trend Micro, when we went through the POCs and other components, we did not find it very strong as far as mobile security is concerned. I think Kaspersky is much better than Trend Micro when it comes to mobile security solutions. From an outside perspective, Kaspersky Endpoint Detection and Response Optimum looks pretty strong and comprehensive. The main improvement would be if they could decrease the cost, as it would be great for clients since it is quite expensive now compared to when it used to be cheaper. The key competitor for Kaspersky Endpoint Detection and Response Optimum is Trend Micro. Trend Micro is the only competitor in the market right now. I would say both Trend Micro Endpoint Detection and Response and Kaspersky Endpoint Detection and Response Optimum are quite similar; I cannot say that one is better than the other. The difference is mainly in cost; Trend Micro has mostly moved all their products to the cloud, offering no on-premises products now, whereas Kaspersky is still in a transition phase providing both on-premises and cloud solutions. Many clients prefer on-premises as it is less expensive compared to cloud.

Product deployment protects assets but needs improvement in system support
I am doing maintenance for Microsoft Defender for Business, and I'm currently working with it. We don't need to use the latest version of Microsoft Defender for Business. We still use the latest virus definition file that Microsoft Defender for Business has automatically updated. We implement a basic update mechanism. Our compliance division manages how many servers and PCs we have and whether those servers have antivirus solutions. I am not certain about how Microsoft Defender for Business helps with AI-driven security strategies. I just use it normally and don't know if it uses AI technology. I rate Microsoft Defender for Business a six out of ten.
