Rubrik protects the backup. Elastio proves what is inside. Deep File Inspection detects zero-day ransomware, slow encryption, and threats that anomaly detection was not built to see.
The risk
Rubrik stores immutable snapshots, enforces retention policies, and orchestrates recovery. None of that tells you whether the data inside the snapshot is compromised.
If ransomware encrypted files before the snapshot was taken, Rubrik faithfully preserves an immutable copy of compromised data. The backup did its job. The threat is inside.
The question is not whether your backups are protected. It is whether they are clean.
What Rubrik delivers
These capabilities are in production across thousands of enterprise environments.
Policy-driven immutability, role-based access, and logical air gap across the backup estate.
Backup data cannot be modified, encrypted, or deleted by an attacker who compromises the production environment.
Flags statistical deviations in backup patterns, file counts, and entropy scores that may indicate an encryption event.
Single pane for backup policy, compliance, and recovery orchestration across hybrid environments via Rubrik Security Cloud.
The gap in the stack
Modern ransomware is designed to stay below it.
What Elastio adds
Elastio adds the inspection layer that Rubrik was not built to provide.
Inspects inside the file content. Not metadata. Not entropy. The actual data. Every file in every recovery point.
Ensemble of detection models trained on 2,300+ ransomware families and 10,000+ variants. 99.995% precision. Catches threats with no known signature.
Identifies intermittent and partial encryption that accumulates below anomaly thresholds across backup windows.
Continuous recovery readiness. The CISO knows the actual recovery posture at any point in time, not the timestamp of the last backup job.
Every inspected recovery point produces enumerated evidence of what was checked, what was found, and what is clean. Recovery you can prove, not recovery you assume.
One inspects. One infers.

How it works
Rubrik creates immutable snapshots, enforces retention, and manages recovery orchestration. Nothing changes in the backup workflow.
Elastio connects to the Rubrik backup environment at the storage layer. No agents. No data movement. No changes to Rubrik policies.
Deep File Inspection runs against Rubrik backup data. Identifies ransomware, malware, and threats that anomaly detection cannot see, including zero-day variants and slow encryption.
Verified Data and R-RPO are delivered to the security operations team. Clean recovery points identified with evidence. Compromised points flagged with classification detail.
FAQ
Everything a CISO, CTO, or security architect needs to evaluate Elastio alongside Rubrik.
Elastio runs real attack simulations against your Rubrik backup data, including slow encryption, zero-day variants, and partial encryption, to show what anomaly detection misses. Most assessments complete within days. Your data. Your environment. Real results.
