Choosing authentication for strict environments
Hi everyone. I am currently evaluating different options for multi-factor authentication setup within our corporate network. We need to comply with rather strict data residency regulations and I have some doubts about cloud options. Has anyone here recently migrated or deployed a self-hosted MFA solution?

Cloud-based authentication seems to be a popular choice nowadays because it is fast to deploy. However my team faces strict compliance requirements like GDPR and NIS2 which makes us look at the infrastructure differently. When authentication data leaves the internal network it creates additional compliance risks. For organizations operating under rigid data residency rules or running air-gapped networks keeping everything local is often the only realistic path. I found this guide https://www.protectimus.com/on-prem-mfa/ useful during my research on how self-hosted multi-factor authentication architectures handle these isolation constraints. It provides a dry and structured breakdown comparing cloud and private-cloud alternatives. In our case keeping complete control over the authentication logs and user data within our own data center helps avoid uncomfortable questions from auditors. It requires more maintenance but the isolation benefits for critical infrastructure seem to justify the resources.
