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.

Have consistently built secure internal environments while implementing compliance tools for diverse customer needs
The customizable alerts system needs improvement. The detection rules are not extensive enough. There should be more possibilities for creating alerts based on additional criteria. While rules can be customized, the available criteria for creating detection rules should be expanded. Microsoft's pricing is very expensive. The Business Premium offering should be extended to enterprise customers, as it's currently limited to 300 users. There should be a tier below E5 that includes Microsoft Purview and other features. Currently, E5 licensing costs approximately 6,000 INR per user per month including taxes. Competitive solutions offer similar functionality at about 50% of Microsoft's cost. Email DLP is included in Business Premium or P1 licenses, while P2 licenses cover endpoint DLP and additional channels. Microsoft should introduce an intermediate tier below E5 that covers all P1 licenses, as customers often need coverage across the entire M365 suite.
