Offers strong identity unification but needs better customization
Microsoft Entra External ID can be improved with additional features, specifically customizable flexibility and a customizable user interface for the login dialog. Currently, the login dialog has very limited customization options, which only include font styles, colors, text messages, or brand icons. Last month, Entra ID introduced some customizable features in their login dialog, but this does not apply to Microsoft Entra External ID, indicating a significant gap between the two. In theory, Entra External ID can support many external identity providers where custom login dialogs could be integrated, potentially via SSO feature coordination, although I have not yet confirmed this. Hence, enhanced customizable login options and the ability to use attribute password logins are critical features that are required for Microsoft Entra External ID to gain dominance in the authentication market.

Journey orchestration has improved fraud prevention but still needs shared rules and better usability
The main improvement needed is that with the tool, you have to build rules for each and every application. There is no common place where you can write the rules and use that rule for all your applications, which is missing. This is a big feature that is missing compared to the other products in the market. Additionally, the SDKs, Journey Player, and other components are not business-friendly, so you really have to be technical to get into it and do those things. A non-technical person would find it really hard to implement and learn things inside Transmit Security. Even though it requires less coding, you still have to have some technical people in your team to really write the rules and integrate those rules into your application.

Quotes from Members

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

Pros

"The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use."
"For policy management in my organization, I would say it is perfect."
"It's quite easy to manage and monitor."
"The impact of having multiple authentication types available significantly helps with security practices using Microsoft Entra External ID."
"I have not encountered any stability issues with Microsoft Entra External ID."
"Primarily Microsoft Entra External ID SSO is valuable as it works with everything when it comes to integration."
"Microsoft Entra External ID is more secure, offering a secure environment."
"The most beneficial feature for us is the ease of setup. With about five clicks, we can generate unique IDs and keys and set up in less than 30 minutes. We can also generate these for multiple years simultaneously, which is convenient."
"Transmit Security has played a major role for our organization, especially in the authentication areas."
"Transmit Security has positively impacted my organization by improving the development of workflows in order to help the user experience."
"Transmit Security has impacted my organization positively because it is reassuring to know that we are building on top of a trusted tool, and we do not rely on developers that could make mistakes, and because it is an authentication platform, that could be detrimental."
"Transmit interface is flexible and user-friendly, which is important for our workload. Switching from one authentication code to multiple exposure or two-factor authentication (MFA) is seamless."
 

Cons

"The training generally is complicated to understand, leading us to often go through a managed service provider."
"The only problem that you might face with Microsoft now is their complex licensing model."
"Technical support needs improvement."
"The authentication methods available are very limited, and this presents a weak point."
"The cost is very high."
"Microsoft Entra External ID isn't a complete cloud-based account solution, as it must handle internal employees and collaborate with internal Active Directory."
"As of latest, when it comes to my experience, I am not satisfied."
"A common concern among the customers I visit is the unpredictability of Microsoft's costs at every renewal. This is really bothersome for the customer, and I would say it is the worst element I have seen in these years."
"The main improvement needed is that with the tool, you have to build rules for each and every application."
"Pricing is an area where Transmit Security could improve. The pricing needs to be more competitive."
"The customer support varies, but overall, we are satisfied."
"The scalability of Transmit Security is a little bit tricky. It is not easy to scale and depends on the complexity of my workflows and how many users I am going to support."
 

Pricing and Cost Advice

"We don't pay separately for Microsoft Entra External ID as it's part of our Microsoft Exchange subscription."
