The Blast-RADIUS issue is a good reminder that network security should not depend on a single layer of authentication. Along with applying vendor patches and recommended protocol protections, businesses can reduce credential-related risks by requiring a second verification step for network access. Protectimus RADIUS authentication with MFA can add this extra check to existing RADIUS environments, helping secure VPN and other network access while still working with Active Directory or LDAP. This layered approach gives enterprise IT teams stronger control over who can access internal resources.
