3 reasons teams choose Cohesity over Rubrik

Overview Beyond Zero Trust
Go beyond Zero Trust

With today’s sophisticated cybercriminals trying to encrypt, exfiltrate, and ransom your data, the need for Zero Trust is a given. You need defense-in-depth capabilities that minimize your attack surface.

Proven Recovery Icon
Gain a proven recovery advantage

When your business is down, every second counts. Recover VMs, databases, and file shares rapidly at scale, without single points of failure risking VM crashes or data loss.

Platform Icon
Streamline with one platform for the future

Get modern data security and backup, either SaaS or self-managed. Use one platform with limitless scale—so you can expand with file services, repurpose data for dev/test, and generally do more.

Comparing Cohesity vs Rubrik



Minimize risk from cyberattacks


Prevention and detection of malicious activity: Modern data immutability/WORM, 2FA/TOTP, VM vulnerability detection, ML-driven anomaly detection, one-click, industry-leading threat protection and data classification


WORM not customizable: Lack of flexibility to lock for different periods in archives vs. local copies, which raises costs, increases compliance risk, shortens protection, and discourages use; no VM vulnerability detection; currently uses manual YARA rules and Regex for threat hunting and data classification


Protection for in-progress backups: Adapters use closed API/RPC protocols and adapterless dump-to-NAS workflows supporting NFSv4.1 ACLs to protect from exfiltration or sabotage


Higher exposure to exfiltration or sabotage: Fewer applications supported by adapters; in-progress NFS dumps may be accessed on the network for exfiltration or sabotage


Strict access control: Quorum support for multi-person concurrence on sensitive actions


Greater risk of rogue actions: No quorum controls to prevent most unilateral admin actions, such as maliciously exporting data


Bank-grade cyber vaulting with FortKnox: Immutability, Cohesity-managed key option; quorum-controlled operations, rapid restore, and time-limited network access (reducing attack surface)


Just a vendor-supplied storage bucket: Customer still responsible for managing multiple risks themselves; fewer layers of protection, doesn’t meet bank requirements or maximize restore speeds

Reduce downtime with rapid cyber recovery


Restore production and populate recovery sandboxes faster: Immediate and scalable restore of VMs and databases for faster forensics, sandboxing, and recovery


Slower recovery: Chain-based metadata processing requires “stitching together” of snapshots when restoring at scale


Reduced downtime: Resume NAS file sharing immediately without restore, and/or rapidly restore to primary storage


Files offline longer: Can’t immediately put file shares online; slow restore to primary


Production-grade I/O reliability: Writes never lost, near instant recovery; not interrupted by reboot or hardware failure


Risk of data loss: Risk of VM interruption or data loss due to node loss or unplanned reboot


Simple closed-loop SIEM, SOAR integration: Complete incident response within Palo Alto XSOAR, Cisco SecureX, Microsoft Sentinel, or Crowdstrike


More complex incident response: Two UIs needed; Palo Alto XSOAR and Microsoft Sentinel integration only

Maximize data value


Speedier data reuse: Rapidly restore to get data immediately for dev/test or analytics


Slower access to data: Less scalable live mounting and restore


Data masking: Anonymize sensitive information before it leaves the backup repository


Potential PII exposure: Dev/test workflows create risk without masking


Single secure data management platform: Enable multiple use cases including file & object services, DR, and copy data management with a reduced attack surface


Just a backup: Single-purpose architecture requires additional silos for use cases beyond backup and recovery

Better TCO


Freedom to choose SaaS, self-managed, or both: Same GUI for SaaS, on-prem workloads, and M365


Either/or: SaaS limited to protecting M365; separate GUI for SaaS administration


25% more space efficient than Rubrik, including across cloud: Typical for most workloads due to superior sliding-window dedupe, Zstd compression1


33% more space required than Cohesity: Typically due to fixed block sizes, limited dedupe across source types and less compression. No dedupe supported for flash media.2


Future proof: Mix between whitebox and your choice of a supported major h/w vendor without an expensive lock-in


Hidden costs: Mixing hardware limited to single vendor

1Space saving estimate based on a typical mix of VMs, databases, and file shares as observed in head-to-head sizing and as relayed to Cohesity by prospects.

2 When Cohesity needs 25% less space, if Rubrik needs 100 TB then Cohesity needs 75 TB; compared to the 75 TB that Coheity needs, Rubrik needs 25 more TB, which is 33% more than Cohesity needs; if Rubrik has not quoted 33% more license than Cohesity, then Rubrik is likely not quoting enough license to provide sufficient in-cluster retention to recover rapidly from sophisticated attackers.
