Azure MFA NPS Extension: Limitations, Costs & On-Prem Alternatives (2026)
The Azure MFA NPS Extension has been the go-to answer for adding a second factor to Microsoft NPS and securing VPN, Wi-Fi, and other network access protected by RADIUS authentication for years. It’s free (if you have the right license), it installs in under an hour, and it works. Until it doesn’t — and when it doesn’t, the failure mode is usually a structural one, not a configuration problem you can fix with a...
Host-Level vs Network-Level MFA: Credential Provider (RDP/Windows Logon) vs RADIUS Proxy (VPN/Wi-Fi)
Managing remote access security requires a decision most teams avoid until something goes wrong: where exactly should MFA be enforced? At the network edge, or on the host itself? The answer isn’t binary — but getting the layer wrong means either leaving critical servers exposed after a perimeter breach, or blocking legitimate administrators from getting in when the network stack misbehaves. This article breaks down the two...
Protectimus vs RSA: MFA Comparison of Features, Pricing, and Integrations
When looking for a reliable multi-factor authentication (MFA) solution, it’s easy to get lost in the variety of options available on the market. To help navigate these choices, we continue our comparison series by examining how Protectimus stacks up against other well-known authentication vendors. In this article, we compare Protectimus and RSA. Both companies offer strong authentication solutions, but they approach the problem from...
How Secure Is Two-Factor Authentication: 2FA Attacks and How to Prevent Them
Two-factor authentication security has improved dramatically in recent years, but attackers continue developing new ways to bypass 2FA protections. Two-factor authentication (2FA or MFA) is one of the most widely used security mechanisms for protecting online accounts and corporate systems. By adding an additional verification step to the login process, it significantly reduces the risk of unauthorized access. However, attackers...
MFA Fatigue Attacks: How They Work, Risks, and Prevention
Multi-factor authentication (MFA) is a well-known and effective measure of protecting access to user accounts. MFA helps to reduce the number of attacks associated with stolen login data. Due to the use of two or more different authentication factors, it’s almost impossible to access the account even if an attacker has the user’s login and password. However, attackers constantly find new ways to bypass two-factor...
