Use Azure MFA With Microsoft NPS (RADIUS) Server
KB ID 0001759 Problem I was in a forum last week and someone asked, “Can I enable Azure MFA, on my RADIUS server, to secure access to my switches and routers etc”. It turns out if you want to enable Azure MFA with Microsoft NPS it’s actually quite simple. So, I’m using RADIUS auth (above) on my NPS server, and it’s simply checking the authenticating user is a member of a domain security group....
O365 with Duo MFA (Without a P1 License?)
KB ID 0001737 Problem Working for a cloud service provider, (and a Duo partner). I get a lot of queries about Duo MFA for Office 365. Typically (I think) the best solution is to enable Azure Conditional Access and couple that with Trusted sites, so clients get challenged when out on the road, but not in the office.

I was initially skeptical but I tried...
Adding Duo 2FA to Microsoft ADFS
KB ID 0001656 Problem I did a Duo run through a few weeks ago, and to be honest their documentation is usually pretty good. I was spinning this up as a PoC for a client so I thought I’d put my take on the procedure here. ADFS Duo Pre-Requisites I already have a Duo Authentication Proxy server setup and my users are enrolled, you will need to set this up first. See the following article; Duo: ADSync and Enroll Users via SMS Log...
AnyConnect: Enable Duo 2Factor Authentication
KB ID 0001650 Problem I was asked if I’d ever set this up the other week. Surprisingly I had not, I’d deployed Duo for other things, but not for Cisco AnyConnect. As I had some other ‘Duo’ related tasks coming up, I was deploying it on the test bench, then adding in my Cisco ASA and AnyConnect wasn’t much more work! Here’s my topology; My ASA is running version 9.1 My Duo Authentication Proxy is...
