User Management

To view the users in your SamurAI tenant, select Admin > User Management from the main menu.

The user list displays information including each user’s name, username, assigned role, account status, creation date, and last login.

Tenant Administrators can invite users, assign and change roles, and delete users from the tenant.

Invite users

Invite users through the SamurAI Portal.

Review the role’s permissions before inviting users. If a custom role is required, create and save it under Admin > Roles before assigning it.

1. Log in to the SamurAI Portal as a Tenant Administrator.
2. Select Admin > User Management.
3. Select Invite users.
4. Select the system role or custom role to assign.
5. Enter the user’s email address. To invite additional users with the same role, select + Add another person and enter their email addresses.
6. Complete the invitation using the controls displayed in the portal.

Each invited user receives an email from no-reply@security.ntt with instructions to register their account and complete their account details.

For registration instructions, see Getting Started with SamurAI MDR.

View a user’s role

Select Admin > User Management and locate the user.

The Role column displays the user’s assigned role.

Each user is assigned one role. The role determines which portal features and information the user can access and which actions they can perform.

For information about system roles, custom roles, and their permissions, see User Roles.

Change a user’s role

1. Log in to the SamurAI Portal as a Tenant Administrator.
2. Select Admin > User Management.
3. Locate the user.
4. Open the user’s more options menu.
5. Select Set role.
6. Select the required system role or custom role.
7. Select Save.

The selected role replaces the user’s previously assigned role; it does not add a second role.

Access for users who work across multiple tenants

When reviewing access for a user who works across multiple tenants, confirm which tenants they need to access and which information and actions they require in each tenant.

Federated View does not grant additional access. Ensure that the user has the appropriate access and permissions for Security Incidents, General Tickets, or both in each relevant tenant.

Assign access according to the user’s responsibilities and the principle of least privilege. A need for consolidated visibility does not, by itself, require the Tenant Administrator role.

For more information, see User Roles and Federated View.

Delete users

Delete users who no longer require access to your SamurAI tenant.

Before deleting a user:

• Confirm that you have selected the correct username.
• Check whether the user is a Tenant Administrator.
• Ensure that your organization retains appropriate Tenant Administrator coverage.

To delete a user:

1. Log in to the SamurAI Portal as a Tenant Administrator.
2. Select Admin > User Management.
3. Locate the user and verify their username.
4. Open the user’s more options menu.
5. Select Delete.
6. Follow the instructions displayed in the portal to complete the deletion.

Use Set role instead of Delete when a user still requires portal access but needs different permissions.

NTT recommends maintaining at least two active Tenant Administrators wherever possible, providing a primary administrator and a backup.

User status

The Account Status column shows the user’s registration status.

Review user access

Review the user list regularly and whenever a user changes responsibilities or leaves your organization.

• Assign the lowest-privilege role that supports each user’s responsibilities.
• Review custom-role permissions as well as individual role assignments.
• Keep Tenant Administrator access limited to users with an administrative or coverage requirement.
• Delete users who no longer require access to the tenant.

For information about reviewing role permissions and assigned users, see User Roles.
