Featured Reviews

Emeka Ndulu - PeerSpot reviewer
Cloud Solutions Architect at a tech services company with 201-500 employees
Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.
MohammedTalukdar1 - PeerSpot reviewer
Enterprise Security Architect at PRS for Music
Identity protection has unified access control and delivers faster, risk-based threat response
The licensing for Microsoft Entra ID Protection is somewhat complex depending on whether you have an E5 or E3 licensing model, so improving the licensing models would make it a lot easier to use. The cost could always be lower; at the moment, I would say it is reasonable, but to get the full suite, you need to go for at least an E5 license, which can be very expensive. Occasionally, when we are trying to do something different in terms of integrating into a new vendor or platform, especially with some of the new SaaS platforms, there are not many out-of-the-box solutions available, so we have to build custom solutions.
