Securing local networks without cloud reliance
Has anyone here migrated their multi-factor authentication back to an on-premise setup recently? We are evaluating our data residency options and I would like to know if managing the infrastructure locally is worth the extra maintenance overhead.

For organizations operating under strict regulatory frameworks like GDPR or NIS2 cloud authentication often introduces unnecessary compliance risks. When user data leaves the network to hit a third-party server auditors tend to ask very specific questions about data residency. This is why a self-hosted architecture remains relevant. I was researching implementation strategies and found this comprehensive guide https://www.protectimus.com/on-prem-mfa/ which outlines how local deployments keep authentication data entirely within your own perimeter. For air-gapped networks or critical infrastructure this approach eliminates reliance on external uptimes. It requires more internal resources than a quick cloud fix but the complete control over encryption keys and logs justifies the effort for high-security environments.
