Heimdall Database Proxy review
A broad database proxy with pooling, routing, analytics, security, and failover.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Heimdall Database Proxy is a data access layer for application developers, database administrators, and architects. It sits between applications and SQL databases in cloud or on-premise environments, providing connection pooling, multiplexing, SQL-aware routing, read/write splitting, load balancing, caching, analytics, security controls, and automated failover. Heimdall supports MySQL, PostgreSQL, Amazon RDS, Oracle, SQL Server, MariaDB, DB2, Greenplum, and Redshift, and is designed to operate without application code changes.
The published plans show a freemium structure. Community Edition includes connection pooling with multiplexing, LDAP group and role synchronization, SQL performance analytics, and database metadata filtering; it is specifically for Greenplum deployments. Standard Edition adds a single proxy VM, query caching, read/write splitting, and connection pooling. Enterprise Edition builds on Standard with distributed auto-scaling proxies and enterprise-level support. Enterprise Plus adds multi-tenant routing for SaaS platforms, database PAM auditing, data masking, and GDPR auditing. Paid purchases are handled through direct licensing or cloud marketplaces.
Platform fit is a central strength. Integrations include AWS RDS, Amazon Aurora, Amazon ElastiCache, Azure, Google Cloud, Google Cloud SQL, AlloyDB, Oracle Cloud, Redis, and SailPoint. The proxy also includes SQL result caching with configurable backends, replication-lag detection, persistent automated failover, LDAP or Active Directory authentication and authorization, and SQL firewall and injection-anomaly detection. Heimdall Database Proxy suits organizations that need one layer for database traffic management across varied environments, especially where routing, resilience, analytics, and governance matter together. Teams seeking only a focused connection pooler or a narrowly scoped database proxy may find its edition structure and wider capabilities more than they need.
