Elastio vs. Rubrik

Rubrik keeps your backups immutable and available. Elastio proves whether the data inside those backups is actually clean. They answer different questions — and work best together.

Two questions. Two products.

Rubrik and Elastio each answer a fundamentally different question about what happens after an attack.

Rubrik
"Can we restore our data if we are hit?"
·Immutable snapshots: ransomware cannot encrypt or delete backups
·Snapshot orchestration and rapid restore workflows
·Anomaly detection: entropy-based, triggers on statistical deviation
·Cloud vault isolation for offsite copies
·SOAR / SIEM integration for backup events
Outcome: Data is available for restore
Elastio
"Is the data we are restoring actually clean?"
·File-level integrity validation, not entropy
·Deterministic pass / fail on every restore point
·Intermittent and zero-day ransomware detection
·Last Known Clean recovery point, continuously maintained
·Provable recovery evidence for regulators and boards
Outcome: Restore point integrity is provable
The GapRead the Accuracy Gap report →

Rubrik was built to detect noisy attacks. Modern ransomware is designed to be quiet.

Entropy detection has a floor.
Rubrik Radar triggers on a sharp entropy increase across snapshot diffs. High-volume attacks cross it. Advanced variants are engineered not to.
Intermittent encryption stays invisible.
Attackers encrypt alternating 4KB blocks. Entropy change stays negligible, file sizes unchanged. Backup completes flagged clean.
Alert fatigue is a real cost.
Entropy-based models require calibration to manage false positive volume. SOC teams running Rubrik at enterprise scale know this. Real events get buried in noise.

After a breach, three questions get asked

1.How was the recovery point selected?
2.How did you confirm the restore was clean?
3.What caused the downtime to last that long?

Rubrik answers question one. Elastio answers question two. Question three depends entirely on whether you had the answer to question two before the incident started.

Proof of concept

Run a recovery integrity assessment in your environment.

1
Advanced encryption techniques deployed against your backup data. You see what your current detection catches and what it does not.
2
The same data hunted by Elastio. Corruption confirmed, Last Known Clean identified.
3
Side-by-side output: alert volume, precision, and confirmed clean recovery point.

If no material gap is found, you retain validated confirmation of your current posture. If corruption is found, you reduce recovery exposure before an adversary tests those assumptions.
