Being a SaaS solution, the scalability of Microsoft Sentinel is robust.

Room For Improvement

Microsoft Defender faces challenges with pricing, integration, AI enhancements, false positives, support, documentation, licensing, and compatibility improvements.
Microsoft Sentinel users desire better integrations, clearer features, improved speed, enhanced AI, and streamlined processes for effective use.
Providing code customization would help keep pace with new vulnerabilities and threats.
The main area of improvement for Microsoft Defender Threat Intelligence is related to how information is conveyed.
From the telemetry data standpoint, I would prefer Defender data to be more open in future updates.
We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel.
Currently, we are happy to have a way in the middle with not so much cost, but it would be nice to have the ability to enhance the automation of workflows based on learned incidents.
There are complexities in calculating the right pricing tier for different customers, which makes it difficult for me as a consultant during upfront pricing.

Microsoft Sentinel's cost perception varies, offering flexibility and integration benefits, yet data volume can significantly impact expenses.
Microsoft Sentinel offers more capabilities than Bastion, with a more intuitive experience.
Setting up the right cost model for customers is intricate, requiring careful consideration of various components and licensing tiers.
The ingestion costs for the data analytics is usually the highest cost.

One of the best features is that it provides a certain level of customization, allowing us to set our spam confidence levels.
Our threat detection is enhanced due to the AI agents in Microsoft Defender Threat Intelligence, which helps in detecting automatically.
Microsoft Sentinel's ability to correlate data from multiple sources and its detection capabilities are essential.

Featured Reviews

Charles Mokoena - PeerSpot reviewer
Has strengthened our ability to detect threats in real time and improved internal security decision-making
The features that I find most valuable in Microsoft Defender Threat Intelligence include the Sentinel part of it. There are several features we've looked at, including Sentinel as well as extended Defender, which is XDR. I've used those two, and that's what I've found quite useful for us, especially in the hardening and analysis part of the whole threat analysis. We use the real-time threat detection features in Microsoft Defender Threat Intelligence. If it wasn't for that real-time threat detection on the vulnerability, I think we would not have survived the attack. The integration capabilities of Microsoft Defender Threat Intelligence with other Microsoft security tools have benefited our organization's threat management process by initially being quite a challenge, especially coming from other security tools such as Fortinet and Check Point. However, once you've gotten used to it, it's quite easy and user-friendly. The dashboard, especially the threat analysis dashboard, is quite detailed in terms of providing a view of which areas in our environment need attention, making it quite useful.
