What is SSO (Single-Sign On)?

SSO (Single-Sign On) is the functionality that allows users to sign-in (authenticate) only once during a whole session, no matter how many applications are being accessed. They can then access their data transparently, without the constraint of retyping a new user name/password couple.

By creating an obligatory passage point between a user and its applications, an organization can effectively control the accesses. Moreover, a log of these accesses and administration operations is kept centrally, which facilitates audit. This facilitates compliance with confidentiality, integrity and availability requirements.

Evidian Enterprise SSO (Single Sign-On)

Free your users from remembering and typing passwords!
Evidian Enterprise SSO provides agile single sign-on to all users, businesses and organizations. By automating password management, Evidian Enterprise SSO simplifies your users’ lives and lets you drive your security policy.

Why do enterprises invest in SSO?

Facilitate access rights administration

Managing users for multiple applications has become time-consuming and also a financial handicap for companies as certain applications share the same authentication, while others have dedicated user bases.
By centralising usernames and passwords, Evidian Enterprise SSO allows administrators to spend less time on password management tasks. This saved time can instead be spent on development of systems and on improving system performance. Evidian Enterprise SSO is a non-intrusive software and the solution is transparent for the end user. The method to detect an authentication window is easy to use and no modifications to applications are needed.

Simplify technology for users

With Evidian Enterprise SSO, passwords are entered and renewed automatically. Users save time and can access their applications with no restrictions. Current applications need not to be modified, neither Windows software nor web applications ( the Windows domain, CRM portal, Oracle or SAP applications, supplier portals).

Employees can get on with their work without worrying about forgotten passwords, and without having to change them regularly according to ever more complex criteria: special characters, length, case, etc.

Optimize your costs

A support call generally costs €15. Thanks to Evidian Enterprise SSO, these calls can be reduced by up to 30 %, as employees no longer will lose the application passwords. Automating connections avoids account lockouts due to typos or faulty keyboards as much as possible.
The cost of ownership and licences associated with applications can be optimized thanks to Evidian Enterprise SSO allowing creation of a list of active accounts for each application. When using Evidian Authentication Manager/SSPR, if a user lose his Windows password, the user can reset his Windows password at any time and without having to contact support.


Reinforce security

By managing passwords’ lifecycle, Evidian Enterprise SSO ensures that accounts’ passwords correspond to your corporate security policies. With Enterprise SSO you will limit password sharing between your employees as well as passwords written down in an unsecure way
Evidian Enterprise SSO can help you strengthen access to your applications by combining Multi Factor Authentication (MFA) to access your most critical applications.

Increase Productivity

Evidian Enteprise SSO provides one unique authentication to login to authorized applications. Users are no longer required to type or memorize passwords across multiple applications, and significantly reduce time needed for daily tasks.

Furthermore, by reducing password fatigue it will also reduce calls to the helpdesk up to 50%.

Compliance and audit

Evidian Enterprise SSO will help you comply with latest data regulations, such as GDPR he solution is CSPN certified.

The solution will also ensure you to keep track of Who had accessed an application, at what time and date, on which workstation and by using which type of authentication method.

Adapts to your business needs

The main function of the product is to prevent users from entering a username and password for each application used. It also allows a user to delegate access to an application to another user without having to disclose their password

Delegate user accounts

What happens if an employee wishes to be replaced by a colleague while he or she is away?

Previously with an unsecured solution, said employee revealed his or her login and password, with all the inherent risks in terms of security and audit. Evidian Enterprise SSO, on the contrary, allows an employee to temporarily delegate access to a colleague. Of course, he or she can only do so if your security policy authorizes it. Moreover, a record of accesses is kept, so you know which operations have been performed by which user.

Shared application accounts

Evidian Enterprise SSO allows users to access shared accounts without knowing passwords. When the account requires a password change, the Evidian solution proceeds to the generation of a new password, and each authorized user will take advantage of it without realizing it.

The use of the shared account is audited by the solution and the administrator may retrieve which user grants access to which application, and when.


For critical applications, Evidian E-SSO can be easily configured to ask for reauthentication to access application. You can reauthenticate with a Password or force the use of MFA for your most critical applications.

4 eyes authentication

When the need of an approval of a third person is necessary to validate a sensitive operation (use case Bank/Insurance/Pharma…), the user and validator can use Evidian E-SSO to securely validate the operation and enhancing security of this 4 eyes authentication by requesting strong authentication to inject the signature.

Enterprise SSO for mobile device

Enterprise SSO for mobile devices (QRentry for Android and iOS) automatically enters application passwords for you, stores securely personal notes and passwords in your mobile eVault. Those information are securely stored in your SSO directory and available from your workstation and your mobile devices.


Evidian provides a series of IAM consulting services to help you build your identity and access management project. These services cover three principle domains:

Implementation/demonstrator’s assistance with implementation/model

Expert testimony


A major player in the aeronautical sector, let’s call it X, decided to provide shared access for all its branches and divisions. At the same time, X had set up a private cloud to store the access portal and shared services. To facilitate access to these services, X wished to offer a Single Sign-On service to its users, and extend this service to all its divisions.
X wanted to simplify the authentication process for users to access the “cloud”, which had to comply with four successive authentications at the time.

Our proposal

We analysed the existing portal

It was a web application installed in the “cloud”, federating access to all divisions, and allowing access to the shared resources of the company. The “cloud” contributed to direct access to shared services such as the CRM, intranet applications, HR, etc.

Choosing the right technical solutions:

  • E-SSO (Enterprise SSO): An SSO device is installed on each workstation. Whenever the user enters a login/password, the SSO remembers it locally. After the user has successfully logged on, the SSO agent waits for the application’s login request. It intercepts those requests and automatically fills in the fields.
  • Web SSO: Web SSO is an extension of the E-SSO device, designed specifically for web applications. A web portal is the interface between the client and the applications.
  • SSO federation.

Analysing each scenario:

  • Scenario 1: Using E-SSO for various divisions
  • Scenario 2: Using WAM for the main portal and offering E-SSO as an option
  • Scenario 3: Integrating the access portal into the WAM and offering E-SSO as an option.

Analysing the costs: in terms of equipment, licences and effort required to implement each scenario.

Offering an analysis of the different scenarios: selection criteria, decision matrix, SWOT table.
