High-Performance FPE Encryption: SecuPi vs. Legacy Encryption
For global enterprises, Format Preserving Encryption (FPE) often becomes a bottleneck for Cloud Analytics. While legacy solutions like OpenText Voltage and Thales rely on resource-heavy external functions, SecuPi delivers a application-transparent, application-transparent approach that eliminates latency and operational risk.
| Capability | Legacy FPE (Voltage, Thales) | SecuPi FPE Solution |
|---|---|---|
| Performance Impact | High: Full column decryption via External Functions for every query with a condition on an encrypted column. | ✓ 10x Faster: Decryption uses SQL optimization and is applied to result sets only to optimize costs. |
| Implementation | Heavy: Requires code changes & view maintenance. | ✓ No-Code: Transparent plug-ins (No SQL changes required). |
| Identity Context | Blind to end-users (Sees Service Accounts only). | ✓ Rich: Captures user name, role, location, purpose, and clearance. |
| Cloud Cost | High: Massive compute overhead on Snowflake/data platforms for decryption. | ✓ Low: Minimal compute footprint using result-set decryption. |
1. The Flaw in Traditional Cloud Encryption
Traditional FPE implementations on platforms like Snowflake and Databricks typically rely on External Functions. This architecture forces the system to decrypt entire columns for every query, adding minutes to execution times and skyrocketing compute costs.
The Risk: The system sees “Service_Account” requesting data, not “John Doe (HR Manager, London).” This violates the NIST Zero Trust Principles of continuous, context-aware authorization.
Application-transparent plug-ins, Identity context, SQL optimization and Result-Set Decryption
SecuPi redefines FPE by instrumenting analytics application calls through Application-Transparent Plug-ins. Instead of decrypting data at the storage layer, SecuPi applies SQL encryption optimization techniques and decryption transparently to the result sets returned to the user.
- ✓
10x Query Performance: By avoiding full-column decryption, SecuPi reduces query times from minutes to seconds. - ✓
Overcoming “Service Account” Blindness: Provides total visibility into the human user. - ✓
User Attribution: Captures the actual end-user identity (Name, Role, IP, Location) before the query is sent. - ✓
Policy Enforcement: If a user’s location changes to an unauthorized region, SecuPi automatically redacts data in real-time.
