Elastio looks in the data. Rubrik looks above it. Rubrik keeps backups immutable and available. Elastio proves whether the data inside those backups is clean. They answer different questions and work best together.
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?"
Outcome: data is available for restore
Elastio
"Is the data we are restoring actually clean?"
Outcome: restore point integrity is provable
Latest Rubrik Release
In December 2025, Rubrik announced Behavioral Anomaly Analysis and the general availability of Turbo Threat Hunting for NAS Cloud Direct. Both strengthen Rubrik's metadata-layer detection. Neither changes the layer at which detection occurs.

Bottom line
Rubrik's December 2025 release improves how well Rubrik reads the signals above the data. The layer where ransomware actually lives, inside the file, is still unread. That is the gap Elastio closes.
Every Rubrik detection capability, including Anomaly Detection, Threat Monitoring, Turbo Threat Hunting, and Behavioral Anomaly Analysis, operates on file system metadata, pre-computed hashes, or YARA patterns. None open the file.
Extension analysis, burst activity, and entropy are signals about the file. Not observations of what is inside. A payload engineered to leave metadata unchanged leaves Rubrik's engine with nothing to flag.
Turbo Threat Hunting queries pre-computed hashes of executables and scripts. Up to 100 hashes per hunt. A zero-day variant with no known hash is invisible by design.
Modern ransomware encrypts alternating 4KB blocks. Entropy change stays negligible. File sizes unchanged. The backup completes flagged clean. The restored data is not.
Metadata-based models require calibration to manage false positive volume. SOC teams running Rubrik at scale know this. Real events get buried in noise.

After a Breach
01
How was the recovery point selected?
Rubrik answers this. Immutable snapshots and orchestration are designed for exactly this question.
02
How did you confirm the restore was clean?
This is the question Rubrik's architecture is not built to answer. It requires inspection inside the file, not signals above it. Elastio answers this.
03
What caused the downtime to last that long?
The answer depends entirely on whether question two could be answered before the incident started. Without a provable clean point, recovery becomes serial trial-and-error across snapshots.
Rubrik's own 2025 research, covering more than 1,600 security leaders, found that 74% of organizations had their backup and recovery systems at least partially compromised, and 86% paid a ransom to recover. The question is no longer whether backups exist. It is whether recovery is provable.

Proof of Concept
Thirty minutes. Your data. Your Rubrik deployment. We show you exactly what Rubrik's current detection catches and what it does not.
1
Advanced ransomware techniques are applied against a copy of your backup data. You see what your current detection surface catches in place.
2
Elastio hunts the same data with Deep File Inspection. Any payload found is surfaced. The Last Known Clean recovery point is identified.
3
Side by side output. Alert volume, precision, and the confirmed clean recovery point. Documented. Timestamped. Audit ready.
If no material gap is found, you retain validated confirmation of your current posture. If a gap is found, you reduce recovery exposure before an adversary tests those assumptions.
30 minutes. We run the demo in your environment.
Rubrik asks "Can we restore our data if we are hit?" Elastio asks "Is the data we are restoring actually clean?" Rubrik keeps backups immutable and available; Elastio inspects file contents to prove the data inside those backups is clean.
No. Behavioral Anomaly Analysis operates on file system metadata — it does not open the file or examine the contents. Turbo Threat Hunting relies on pre-computed hashes; a zero-day variant with no published hash is outside its scope by design.
Executable and script file types under 15 MB, including Windows extensions such as .exe, .dll, .bat, .ps1, .cmd, .js, and .vbs. Payloads embedded in databases, logs, archives, or structured data files fall outside what Rubrik inspects.
Modern ransomware encrypts alternating 4KB blocks. Entropy change stays negligible. File sizes are unchanged. The backup completes flagged clean. The restored data is not.
Rubrik reports scanning approximately 80,000 snapshots per minute against the hash catalog. Each hunt supports up to 100 hashes.
Yes. Rubrik handles availability (immutable snapshots, orchestration, rapid restore). Elastio handles content integrity (Deep File Inspection, Last Known Clean recovery point). They answer different questions and work best together.
