Description:
Is a home NAS reliable and secure enough to replace corporate cloud storage for daily work, team collaboration, and backups? What security, compliance, and availability measures should I implement (VPN/TLS, disk encryption, user permissions, offsite/air-gapped backups, UPS) and how do I handle versioning and sync for multiple collaborators? Also, how should I raise this with my employer to avoid policy, legal, or audit problems?

Home isp has no sla and limited upload, use dual uplinks or a colo relay, keep encryption keys off-site and maintain hardware warranty
A home NAS can work, but don't fool yourself, the system would rather you rent cloud storage forever. Add MFA, SSO or AD integration, host-side antivirus and endpoint controls, send logs to a SIEM, and make immutable, offsite snapshots that you actually test by restoring. Use S3-compatible object versioning or Nextcloud with file locking for multi-user sync, and treat RAID as not-a-backup. When talking to your employer, present a short risk assessment, recovery time SLA, legal review, and a signed IT exception or pilot agreement so audits and compliance teams can sleep at night.
