Companies always looking for solutions to improve their security and simplify collaboration. In today’s workplace, it’s very common for organizations to work with external partners. Office 365 is a great solution to collaborate with people both inside and outside your organizations, as it provides an easy way to share documents with external users or invite them to join your Microsoft Teams. Unfortunately, when you share using the default methods, your external users aren’t subject to the same security policies, such as multifactor authentication, that you’ve set up for your internal users.
What most organizations are looking for is a way to manage external access that is predictable and consistent with their security practices. A hidden gem that is part of Azure Active Directory and solves this problem is leveraging Azure Active Directory B2B users. Azure AD B2B is not a different version of Active Directory, but just an additional feature that allows one organization to invite members from other organizations to share application access. This tool is beneficial not only for seamless collaboration, but it decreases the worry of security issues.
When working with external organizations or contractors, granting access to your files and resources is important, but it's also important to manage these privileges. The issue does not lie with granting access to new users, but in managing them. Here are the common problems:
Azure AD B2B works by allowing external users access to another organization’s resources, but it applies that companies’ original security policy and leaves the management of the account to the host organization. You can granularly control which resources the account can access in your tenant and can enforce your security policies—like Multi-Factor Authentication (MFA) if they weren’t required before. We can even automate the process in most cases.
Here’s how it works:
When partnering or working alongside other companies, they are some things to be considered:
Azure AD B2B aims to solve these problems and still allow you to be in control. When you invite a new user to your application, they will get access using their Azure AD account. There is no need to create multiple new accounts or multiple new passwords. The new user will sign into your app with their credentials. You are still able to manage and control your application because you can decide if the login will require MFA and who has access.
Azure AD B2B provides an Application Programming Interface (API) so you can build onboarding processes and send invitations to apps or you can use the default service. This simplifies things by creating safe and secure collaboration.
Guest access for the free tier of Azure Active Directory is included with the Office 365 service. This allows you to create users within Azure Active Directory and assign rights to them. A guest user is defined as someone who is not a member of your organization or your organization’s affiliates. Some types of users are specifically prevented from using guest access. These include employees, on-site contractors, and on-site agents.
The Azure Active Directory Premium Plan 1 (AAD P1) is the next step up in functionality and includes features like multifactor authentication and conditional access. It is sold standalone, as part of the Enterprise Mobility and Security Suite (EMS) E3 and the M365 E3 bundle. If the host organization owns AAD P1, then they get external sharing rights included. The rights are granted on a 1:5 ratio. For each AAD P1 license (or bundle that includes it) that is assigned to a user, the company can invite up to five guest users and leverage the same features. Microsoft calls this functionality and licensing privilege Azure AD B2B. Plus, if the guest user already has an AAD P1 license assigned to their identity by their own employer, then it will not even count against the guest license allocation. For more details, read Azure Active Directory B2B Collaboration Licensing Guidance – an article from Microsoft.
The Azure Active Directory Premium Plan 2 (AAD P2) works the same way. So, if document level encryption and control are needed, guests can also share in that functionality on a 1:5 basis.
