Active Directory Certificate Based Multi-Factor Authentication with Office365

Customer: Chemicals Manufacturer

Chemicals Manufacturer uses Office 365 services including Exchange and Skype for Business and wanted to implement multi-factor authentication using their internal Active Directory Certificate Services as the second authentication challenge. I was responsible for configuring ADCS certificate templates, online responder, CRL lists and ADFS so that SSO would challenge for certificate based MFA only from external networks and exclude Skype for Business from MFA as it was unsupported at the time.
