DBX vs Defensia Database Security

DBX is a web-based security analysis tool for PostgreSQL and Supabase databases. It examines how identities can reach database objects through RLS policies, grants, functions, storage, relationships, and tenant boundaries. DBX inspects live security objects and uses a deterministic rule engine and permission graph to evaluate practical access. It groups individual weaknesses into attack paths and reports severity, confidence, and evidence. Each deterministic finding includes a proposed migration linked to the relevant object, with an expected security effect and compatibility risk. The snapshot contains catalog metadata, including schemas, policies, grants, routines, and relationships, but no database rows. DBX says its snapshot workflow requires no database password, persistent connection, agent, or production write access; scanning is designed for a dedicated least-privilege role with catalog permissions. A language model explains verified findings and drafts remediation for human review. DBX does not test application code, network controls, or client authorization logic, and it makes no compliance certification claims. Free unlimited introspection is available; Full Remediation costs $195, paid once.

Defensia Database Security detects database ports exposed to the network and monitors authentication failures that may indicate brute-force attacks. Its agent monitors authentication logs for MySQL/MariaDB, PostgreSQL and MongoDB, and checks Redis port exposure. At startup, it checks ports 3306, 5432, 27017 and 6379; a port bound to 0.0.0.0 creates a dashboard advisory. Repeated authentication failures can trigger IP blocking through iptables or nftables. The agent runs as a systemd service and detects MySQL, PostgreSQL and MongoDB log files automatically. It requires Linux kernel 4.x or newer, root or sudo access, and HTTPS access to the Defensia panel. Deployment options include Docker, Docker Swarm and Kubernetes, with a Helm chart for Kubernetes. The dashboard shows attack timelines, blocked IPs and port advisories. Free is free, with one server, 2,000 events/month, three days of log retention and monitor mode only. Pro is €9 a month, with unlimited servers and events and 90 days of retention.
