CST VerdictBased on our analysis of NIST CSF 2.0 coverage, company size fit, deployment model, here is our conclusion:
Arcserve Cyber Resilient Storage
Mid-market and enterprise teams building ransomware recovery capacity should consider Arcserve Cyber Resilient Storage for its immutable backup architecture, which isolates recovery copies from production networks where encryption spreads fastest. The vendor maps directly to NIST RC.RP (incident recovery plan execution), meaning the product is built around getting you operational again post-attack rather than preventing it upstream. Skip this if your priority is detecting threats before they land; Arcserve emphasizes recovery speed over prevention, which is the right bet only if you've already invested in detection layers elsewhere.
Teams running mission-critical applications on AWS who need sub-hour recovery times without buying dedicated disaster recovery infrastructure should start here; AWS Elastic Disaster Recovery eliminates the capital expense of standby hardware by recovering directly into AWS at scale, and the free tier lets you test failover before committing. The service handles continuous replication of on-premises and cloud servers, so your RTO is limited by your network throughput, not your backup window. Skip this if your applications live outside AWS or if you need orchestrated failover across multiple cloud regions; Elastic Disaster Recovery is AWS-centric by design.
