We deliver. We don’t just advise.

Veeam Backup & Replication design, immutable backups to Azure Blob, RPO/RTO validation, and DR runbooks tested end to end.
Active Directory & Hybrid Identity
AD design and cleanup, Group Policy, Entra Connect sync, Conditional Access, and MFA. Clean hybrid identity, isolated by tier.

Azure Hybrid Cloud Advisory
Migration, identity, governance, and cost optimization. Production-ready architecture, validated before a single resource ships.
