Anomaly and entropy monitoring cannot detect modern ransomware. Elastio uses Deep File Inspection and produces a deterministic verdict per file, per recovery point.
Backup vendors ask whether your backup looks unusual. Elastio asks whether the file itself is corrupt.
“Does this backup look unusual?”
OutcomeStatistical inference. Not evidence.
“Does this file show any sign of ransomware?”
OutcomeProvable recovery. Not assumed.
The ransomware families that cause incidents today were engineered specifically to evade entropy and anomaly detection.
Encrypts every other 4 KB block. The overall entropy change stays below the statistical noise floor. Anomaly tools see nothing unusual.
Encryption schemes that mimic the statistical signature of compressed or benign data. Entropy-based detection produces no alert.
Attacks file headers or metadata while leaving bulk data statistically normal. The file reads as intact until restore is attempted.
Side-by-side view across detection method, evasion resistance, data coverage, and outcome.
| Capability | Backup Vendors | Elastio |
|---|---|---|

| Entropy-based detection (measures data randomness) | Yes | No |
| Anomaly detection (monitors behavioral deviation) | Yes | No |
| Deep File Inspection (validates internal file structure) | No | Yes |
| Deterministic pass / fail per file | No | Yes |
| Known malware signatures (YARA / hash matching) | Partial | Yes |
| Zero-day ransomware detection | No | Yes |
| Evasion Resistance | ||
| Intermittent encryption detection | No | Yes |
| Low-entropy encryption detection | No | Yes |
| File header / metadata corruption detection | No | Yes |
| Detection independent of entropy or statistical noise | No | Yes |
| Coverage | ||
| Live data (VMs, filers, object stores) | No | Yes |
| Replicated data (snapshots, replicas) | Partial | Yes |
| Backup data | Partial | Yes |
| Last Known Clean recovery point identification | No | Yes |
| Resilience RPO (R-RPO) | No | Yes |
| Outcome | ||
| False positive rate: operationally actionable | No | Yes |
| Provable recovery compliance reporting | No | Yes |
| Confirmed clean restore point before recovery | No | Yes |
The Hunt Engine runs Deep File Inspection across live data, replicated data, and backup data. It produces two outputs: Verified Data and a Provable Recovery point. No statistical guessing. No tuning required.
How was the recovery point selected?
How did you confirm the restore was clean?
What caused the downtime to last that long?
Your current backup vendor detection runs against a data set containing intermittent and low-entropy encrypted files. You see exactly what it catches.
Elastio Hunt Engine runs against the same data. Corruption is confirmed. Last Known Clean recovery point is identified.
Side-by-side output: alert volume, false positive count, confirmed clean recovery point, and R-RPO exposure.
If no gap is found, you retain validated confirmation of your current posture. If corruption is present, you reduce recovery exposure before an adversary tests those assumptions.
Modern ransomware families are engineered specifically to evade entropy and anomaly detection. Neither method opens or inspects the file. They observe signals about the file rather than what is inside it.
Intermittent encryption encrypts every other 4 KB block. The overall entropy change stays below the statistical noise floor, so anomaly tools see nothing unusual.
Encryption schemes that mimic the statistical signature of compressed or benign data. Entropy-based detection produces no alert.
An attack on file headers or metadata that leaves bulk data statistically normal. The file reads as intact until restore is attempted.
Deep File Inspection validates the internal file structure and produces a deterministic pass or fail per file, per recovery point, independent of entropy or statistical noise.
Yes. Elastio covers live data (VMs, filers, object stores), replicated data (snapshots, replicas), and backup data with all hunt types. Backup vendors typically partially cover replicated and backup data and do not cover live data.
Statistical detection produces alert volume that renders alerts operationally unusable. Elastio produces a deterministic pass or fail per file with an operationally actionable false positive rate.
Yes. Elastio identifies the Last Known Clean recovery point and provides Resilience RPO (R-RPO) measurement and provable recovery compliance reporting. Backup vendors do not.
