Single Sign On (SSO / IAM) expert to advise best solution for our business

I am looking for an expert in the design and implementation of SSO and IAM solutions to talk me through the best options available for my business (www.crsystems.co.uk). You must have experience of several implementations and be able to explain the pros and cons of SAML , Open ID, Auth0, Okta, and OneLogin from a technical, user and cost point of view. (2 hours)

After completion of the discussion you will provide us with a short document that summarises the agreed best technology route for our company together with a two page (maximum) summary (including diagrams) that we can then pass onto our clients. (2 Hours)

We have our own development team, but we may ask you to project manage the solution, but this is not part of this project.

You must be fluent in spoken and written English and be available during UK working hours via Skype or Zoom.
