Instead of Defensia Database Security
Defensia Database Security alternatives
Defensia Database Security centers on exposed database ports and authentication attacks. Its Linux agent checks ports at startup, monitors authentication logs for MySQL/MariaDB, PostgreSQL, and MongoDB, and detects Redis exposure. Repeated login failures can trigger IP blocking through iptables or nftables. The dashboard brings together attack timelines, blocked IPs, and exposure advisories, and deployments include Docker, Docker Swarm, and Kubernetes. Free covers one server in monitor mode; Pro adds blocking, longer log retention, unlimited servers, and Slack, Discord, and webhook alerts.

A different tool may fit better if you need cloud posture rules, broader engine benchmarks, external asset discovery, secret management, or focused SQL Server, PostgreSQL, or Oracle assessment. Defensia requires Linux kernel 4.x or newer, root or sudo access, and HTTPS access to its panel; it does not offer agentless scanning. Its free plan limits use to 2,000 events per month, three days of retention, and monitoring without blocking, while Pro costs €9.00 per month. When switching, weigh database coverage, deployment and access requirements, whether the product monitors attacks or assesses configuration, and the evidence and remediation it provides.
