I have MFA enabled…but I never get prompted on my PC

With the adoption of MFA (multi-factor authentication) ramping up significantly to help thwart BEC (Business Email Compromise), some people have noticed that the end-user experience isn’t quite what they expected when using their PC.  They aren’t getting prompted the first time each day they use their browser for Office 365, or even when their password [...]

How do I monitor redundancy?

I frequently reference a conversation I had with a client a while back.  It went something like this: Client:  I thought we had redundant firewalls!  Why are we down?!? Me:  You do have redundant firewalls, and it has worked great for the past 9 months while one of the units was failed.  However, the second [...]

Importance of periodically validating your Sender Policy Framework record

A frequent topic of my blogs is the need to confirm that what you did 6 months ago is still valid today.  While there are improved methods for protecting your domain from being spoofed (such as DKIM/DMARC), one of the core methods is using the Sender Policy Framework (SPF) record.  This DNS record essentially defines [...]

Still have ADFS? Time to reconsider.

Microsoft keeps adding and enhancing features in Office 365 and Azure which help simplify and reduce the dependency of on-premises resources. A few recent enhancements have made it possible to replace ADFS in many of our client’s environments.

Are you staying current? Some Windows 10 builds don’t receive updates. Keep up!

Were you an early adopter of Windows 10?  Are you wondering why you’re not receiving security updates anymore?
