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.

Implementing seamless integration boosts secure access and supports Zero Trust
What I appreciate the most about Microsoft Entra ID is that it integrates seamlessly with all the Defender products and is easy to use. Microsoft Entra ID's integration capabilities influence our Zero Trust model by allowing us to enforce our Zero Trust model. Conditional access policies allow us to leverage Microsoft Entra ID to verify that devices signing in to our cloud services are coming from registered devices, and that people are passing all the other requirements we have in order to complete sign-on or conditional access policies. Since implementing Microsoft Entra ID, I've observed changes in the frequency and nature of identity-related security incidents. The organization already had it implemented when I arrived, and I've been working to enhance it. Better configuration of Microsoft Entra ID has allowed us to better protect our organization from threats. Having it alone isn't a solution, but ensuring proper configuration goes a long way in preventing future compromises. My company's approach to defending against token theft and nation-state attacks has evolved since implementing Microsoft Entra ID. We haven't experienced any known compromises from nation-state attacks, and implementing newer features gives me more confidence in our protection. Regarding device-bound passkeys in Microsoft Authenticator and our approach to phishing-resistant authentication, we are currently implementing Microsoft Entra ID certificate-based authentication. Adding a strong form of MFA is important as we found it to be the most cost-effective way. While other solutions might be equally or more secure, they are significantly more expensive. Having worked as an IT consultant mainly with the Microsoft stack across various industries, I have experience with different identity management solutions. Microsoft Entra ID remains the best option. The major advantages when comparing it to Okta include integration with Defender products, Defender for Identities' integration with conditional access policies, and insider threat management integration for blocking sign-ins based on risk factors. The enhancement of Microsoft Entra ID's implementation is relatively straightforward. My main concern is the occasional lack of documentation and the frequency of changes, which can make feature location challenging.
