Dinesh Jaisankar - PeerSpot reviewer
Cloud Architect at Vision Bank
Security architecture shields infrastructure but dashboard needs enhancement
The Azure DDoS Protection plan is essential for environments like ours that are highly exposed to potential attacks, especially since DDoS attacks have become common. The security architecture with Azure DDoS Protection is critical for safeguarding our financial organization's infrastructure. Although implementing it is pricier, it is worth using since our applications are entirely in Azure.
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.
