DatabaseGuard

DatabaseGuard is a database security platform designed to protect relational databases from unauthorized access, tampering, and data exfiltration. The product implements multiple layers of protection, including real‑time intrusion detection, encrypted communication, fine‑grained access controls, and continuous logging and auditing of database activity. It supports major database systems such as MySQL, PostgreSQL, Microsoft SQL Server, and Oracle.

The software was first announced in 2018 by a startup founded by former database administrators and security researchers. Early releases focused on database firewall rules that could be defined via declarative policies. Since then, DatabaseGuard has expanded to include automated threat hunting dashboards and integration with SIEM platforms. The company has raised several rounds of venture funding and announced a partnership with cloud‑service providers to embed the solution in managed database services.

Key functional components include a Proxy‑based architecture that sits inline between application clients and the database server, a policy engine that parses declarative rules, a helically monitored event engine that flags suspicious SQL patterns, and an optional sandbox sandbox for testing new policy changes. The platform also offers built‑in protection against SQL injection, privilege escalation, and storage‑of‑sensitive data. For auditing and compliance, DatabaseGuard generates detailed reports that satisfy standards such as GDPR, PCI‑DSS, and HIPAA.

Deployment models cover on‑premises, virtual appliances, containers, and cloud‑native microservices. A subscription‑based licensing model provides different tiers, including a free community edition with core firewall features. The product is written in Go and C++ for high performance and is distributed under a commercial license that permits use under the terms accepted by the vendor.

DatabaseGuard is frequently cited in security whitepapers and has been evaluated in independent penetration‑testing studies. It remains a niche but growing solution for organizations that require tight regulatory controls and high‑confidence threat detection on operational databases.
