Enhanced visibility and exposes vulnerabilities but needs more integration
I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"It seems to be better at protecting from cyberattacks."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"It has things like conditional access. For example, if someone is accessing sensitive information, then we could force them to do multi-factor authentication. Therefore, we can stop access if it is coming from a location that we did not expect."
"The implementation of Microsoft Entra ID has definitely made app access easier and more seamless for working with Azure registered apps by allowing them to be integrated within the system and setting up SSOs and secure authentication through Entra."
"The most valuable feature of Azure AD is its ability to connect with services outside of Microsoft, although documentation is necessary to properly implement these connections."
"What I appreciate the most about Microsoft Entra ID is that it integrates seamlessly with other Microsoft products, which streamlines the process."
"The user management groups are valuable. It is a pretty basic product, but user management, in general, is valuable with the ability to differentiate between business lines and add different policies, group-based management, and dynamic user groups."
"It has made our work easier in that it’s simplified everything for us."
"Technical support has been great."
"Active Directory itself is the best feature it has. It also gives us a single pane of glass for managing user access."
 

Cons

"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"With Microsoft, support is always crazy, it's not easy to get support."
"In my opinion, Microsoft sometimes releases products too early without providing enough documentation. Our team works with innovative solutions like verified ID, identity governance ,and lifecycle workflow. When we started with lifecycle workflows, we had only two integrated worklows. Still, we couldn't find much of the information we needed in the documentation about our use case or how to leverage IDs in our proof of concept."
"Some of the features that they offer, e.g., customized emails, are not available with B2C. You are stuck with whatever email template they give you, and it is not the best user experience. For B2C, that is a bit of a negative thing."
"Microsoft should work on enhancing its machine-learning algorithm to prevent unnecessary lockouts of users."
"I rate Microsoft support four out of 10. Tier 1 and Tier 2 support could be better. It's not timely or professional."
"Whatever business requirements we needed in the past three years, users were created, with the name of the user and they were not connected with the Active Directory. We were trying to in house in three years and with directory, but we were not able to achieve it."
"Many people believe that the Azure Active Directory is overly complicated and antiquated."
"I'm satisfied with the features provided by Microsoft. They are continually improving their offerings, and I don't have any downsides or issues with Microsoft Entra ID. We're integrating a lot of Azure virtual machines and utilizing the Azure side. We love Microsoft licensing, all that stuff. And Yeah. It's just, you know, just using the CSP portal as well has just been a game changer for us too."
"The variety of different group types has caused challenges in areas where we have Microsoft 365 groups, distribution groups, and security groups, and the different types do not always make programmatic management clear."
 

Pricing and Cost Advice

Information not available
"I give the cost a three out of ten."
"Microsoft Authenticator is included in the package when we purchase a license from Microsoft."
"The pricing for companies and businesses is okay, it's fair. But if you are trying to teach someone about Azure AD, there is no licensing option for that... It would be nice to have a 'learning' license, one that is cheaper for a single person."
"Be sure: You know your userbase, e.g., how many users you have. You choose the right license and model that suit your business requirements."
"It is bundled with other services and the pricing is quite reasonable."
"Entra's pricing is somewhat higher compared to AWS."
"It's really affordable."
"I don't pay for it. Going by how I feel, I see the prices for any MFA solution going down because the more different alternatives there are, the cheaper things should be. Microsoft Authenticator app would be the preferred application, but there are too many ways to implement MFA. I don't know how much it cost, but the price should go down."
