Arcserve Cloud Cyber Resilient Storage vs Keepit Backup for Microsoft Entra ID: Side-by-Side Comparison (2026)

Arcserve Cloud Cyber Resilient Storage

Mid-market and enterprise teams that treat ransomware recovery as a business continuity problem, not just a backup problem, should evaluate Arcserve Cloud Cyber Resilient Storage. The platform maps directly to NIST RC.RP (Incident Recovery Plan Execution) and PR.IR (Technology Infrastructure Resilience), meaning it's architected around restoration speed and immutability rather than just data storage. Skip this if your priority is real-time threat detection or preventing the initial compromise; Arcserve assumes the attack succeeds and focuses on how fast you can get operational again.

Keepit Backup for Microsoft Entra ID

Mid-market and enterprise security teams managing Entra ID across multiple tenants need Keepit Backup for Microsoft Entra ID because it stores identity data outside Microsoft's infrastructure, eliminating the risk of a single compromised tenant taking your backups with it. The immutable storage architecture with ransomware prevention directly addresses NIST RC.RP recovery requirements that most identity backup tools skip. Skip this if your organization treats Entra ID recovery as a nice-to-have rather than critical path; the API-only integration requires intentional deployment planning that doesn't suit teams wanting zero-touch setup.
