Eon vs. Cohesity

Why Are Cloud Teams Upgrading from Cohesity to Eon in 2025?

Feature Comparison:Eon vs. Cohesity

1. Deployment & Architecture

Cohesity’s virtual cluster nodes must be deployed inside your cloud, where they require ongoing maintenance, scaling, and patching. You also foot the bill for those nodes, including compute, storage, and all operational overhead.

Eon skips all of that:

  • Fully agentless and SaaS-based
  • No provisioning or scaling required
  • Zero customer compute

2. Backup Posture Management

Cohesity users still manage backup scope via tagging and static policies, which don’t scale well in dynamic multi-account environments.

Eon introduces full Cloud Backup Posture Management (CBPM):

  • Auto-discovers workloads, databases, volumes, and storage
  • Classifies resources by compliance tier
  • Applies protection policies automatically
  • Flags under-protected data at backup time, not just at restore

3. Recovery & Access

Cohesity offers strong snapshot capabilities, but often at the VM or full-volume level.

Eon enables:

  • Instant restore of files, RDS records, EC2 images, and S3 objects
  • Searchable snapshot index across clouds
  • Sub-minute RTO with no full-system restore
  • Live exploration of backup contents before recovery
  • Restores across clouds, giving hybrid and multi-cloud teams unprecedented agility without retooling

4. Ransomware Protection

Cohesity emphasizes immutability, but its capabilities are limited beyond that.

Eon adds intelligence:

  • Anomaly detection based on data entropy and config drift
  • Alerts for unusual backup behavior
  • Clean snapshot preservation beyond policy limits
  • Smart rollback with point-in-time restore from known good versions

5. Cost & Operational Efficiency

Cohesity adds cost through infrastructure, versioning-based storage, and licensed ransomware modules.

Eon reduces spend across the board:

  • True incremental S3 backup
  • No object rounding or versioning waste
  • Deduplication across regions
  • Handles massive data volumes without rehydration delays or proxy sprawl
  • No upcharges for posture, detection, or query features
  • Makes backups usable for more than just recovery (data lakes)
