Problem
You can monitor your database. But you cannot intervene.
Performance, security, and compliance — three forces pushing at once. Today's tools all speak after the fact.
You can monitor.
But you cannot intervene.
- Missing indexes
- Lack of query optimization
- Maintenance deficiencies
- Insufficient DBA capacity
- Hardware bottlenecks
- SQL injection attacks
- Brute force attempts
- Audit
- Data leaks
- Data masking
- Backup management
- DB metrics
- Query diagnostics
- Bottleneck detection
- Alarm generation
All-in-one SQL Control Layer
One layer. Five capabilities that matter.
Quentra unifies gateway, firewall, audit, monitoring and anomaly detection in a single control point. No application changes required.
Smart Gateway
Intercepts SQL traffic at the protocol layer — enabling real-time control without changing applications.
DB Firewall
Detects and blocks malicious or risky queries before they reach the database engine.
Audit
Captures every query with full context — for compliance, traceability and deep analysis.
DB Monitor
Provides real-time visibility into query performance, bottlenecks and system behavior.
Anomaly Detector
Uses AI to identify unusual query patterns, attacks and performance anomalies instantly.
