Defensia Database Security

Purpose: Defensia detects exposed database ports and monitors database authentication failures for brute-force attacks.
Database coverage: It provides full authentication-log monitoring for MySQL/MariaDB, PostgreSQL, and MongoDB, plus Redis port-exposure detection.
Port checks: At startup, the agent checks ports 3306, 5432, 27017, and 6379 and creates a dashboard advisory if a port is bound to 0.0.0.0.
Automatic blocking: Repeated authentication failures can trigger IP blocking through iptables or nftables.
Installation: The agent installs as a systemd service and automatically detects MySQL, PostgreSQL, and MongoDB log files.
Requirements: The agent requires Linux kernel 4.x or newer, root or sudo access, and HTTPS internet access to the Defensia panel.
Supported deployment: The product supports Docker, Docker Swarm, and Kubernetes deployment, including a Helm chart for Kubernetes.
Dashboard and events: The dashboard displays attack timelines, blocked IPs, and port-exposure advisories.
Pro integrations: The Pro plan lists Slack, Discord, and webhook alerts.
Free-plan limit: The free plan allows one server and detects attacks in monitor mode without blocking them.
Privacy and data: The privacy policy says account passwords are cryptographically hashed and that connected-server data includes hostnames, IP addresses, operating-system information, and security events.
Privacy compliance: The privacy policy says Defensia is committed to handling personal information in compliance with GDPR and other applicable data-protection laws.
Support: The Free plan includes community support, while Pro includes priority email support.
Headquarters: Barcelona, Spain
