Room For Improvement

Cortex XDR needs better integration, pricing, UI, feature parity, and automation, while reducing resource use and false positives.
Microsoft Defender XDR requires better integration, simpler UI, enhanced threat intelligence, streamlined onboarding, improved documentation, and more affordable pricing.
Users face dashboard complexity, system integration challenges, and resource demands, affecting performance, policy control, and pricing transparency.
Improving reporting and dashboard customization, along with the addition of real-time and exportable reports, would help SOC teams greatly.

Setup Cost

Cortex XDR offers competitive pricing between $55-$90, though setup costs are high, with flexible licensing for cloud and on-prem use.
Microsoft Defender XDR offers low setup costs but complex pricing, requiring careful planning to manage licensing and regional updates.

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.

Integrated defenses have unified threat hunting, phishing simulations, and identity investigations
I appreciate Microsoft Defender XDR's MDE, Microsoft Defender tool, which has Attack Simulator. Instead of doing a phishing campaign and getting a separate tool, Microsoft Defender XDR does it all. These features of Microsoft Defender XDR have helped us conduct a phishing campaign quarterly, which has been beneficial. I also appreciate the fact that it has Defender for Office integrated, Defender for Identity, and everything integrated together. I would describe the process of using Microsoft Defender XDR to prioritize incidents in my security operations as quite decent. I appreciate the automatic alerting system where any incidents or alerts we receive come directly to our email. From there, we can open the email, go directly to Microsoft Defender XDR, and start our investigations and remediations. I perceive the integration of security and identity access management in Microsoft Defender XDR as affecting my identity protection strategies very well because it is well integrated with Purview, integrated well with Entra ID, and integrated well with Exchange. I especially appreciate MDO, the Office product. If anything happens and I want to conduct an investigation, it takes me directly to Exchange, where I can also investigate any emails or phishing incidents. Instead of going to different portals, everything can be done from Microsoft Defender XDR. If necessary for further investigation, Microsoft Defender XDR then directs me to that environment. I would assess the integration of AI in guiding security actions within Microsoft Defender XDR as quite positive. Recently, Security Copilot went big, and it is beneficial that I can use that, especially to write KQL. I can do threat hunting features and intelligence all within using Microsoft's Security Copilot. It also has a nice AI feature for threat hunting. I know that all the Defender logs go to Sentinel, and I can pull it up from Microsoft Defender XDR or from Sentinel. The fact that I can actually do all that within Microsoft Defender XDR is a nice feature. In the top module, I can do threat lookups, and I can actually type KQLs in Microsoft Defender XDR and look up incidents. Predictive shielding has had a nice impact on my proactive security measures. It is beneficial that it has, similar to Entra ID, a secure score. For me to improve the product, the secure score helps me out. If I rate it from highest to lowest, I can see what things I can improve. Secure score helps me see what areas I can improve in Microsoft Defender XDR to increase my score and bring it to 80 or more. Knowing Microsoft Defender XDR from using it since 2019, before COVID days, I know that they have improved significantly. It is much more user-friendly and has a very nice vulnerability feature that I find handy and useful. The fact that this feature integrates into Intune is also very decent.

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.
