Defensia Database Security review
A low-cost Linux defense layer for exposed database ports and authentication attacks.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Defensia Database Security is an agent-based security tool for teams running MySQL, PostgreSQL, MongoDB, or Redis on Linux servers. It checks database port exposure, monitors authentication logs in real time, detects brute-force patterns, and presents events in a hosted web dashboard. The product suits teams that need practical visibility into publicly exposed database services and a way to respond to repeated authentication attacks. It is less suited to organizations seeking broad database vulnerability assessment, privilege analysis, compliance templates, or cloud-provider database review.
Pricing is straightforward. The Free plan covers 1 server, monitor mode only, 2,000 events per month, a real-time dashboard, 3 days of log retention, and community support. The Pro plan costs €9 per server per month with monthly billing and adds unlimited servers, protected mode, unlimited events, a Web Application Firewall, CVE advisory intelligence, and priority email support. Pro also enables automatic blocking through iptables or nftables. A 14-day free trial is available. The free tier is appropriate for a small, observation-focused deployment; Pro is the practical choice when active blocking, broader server coverage, or higher event volume matters.
Its main strength is focused Linux exposure defense: it checks ports 3306, 5432, 27017, and 6379, automatically discovers supported database logs, and provides remediation advisories for exposed ports. Docker and Kubernetes fit teams managing containerized workloads, while Slack, Discord, and webhooks support alert delivery. The trade-off is the required server agent and the product’s narrow scope. Choose Defensia for affordable monitoring and authentication protection on Linux servers; choose an alternative when agentless scanning or deeper database security analysis is a priority.
Defensia Database Security pros and cons
- Where it wins
- Checks common MySQL, PostgreSQL, MongoDB, and Redis ports
- Detects brute-force patterns and can block repeat offenders
- Open source with Docker, Kubernetes, Slack, and webhook integrations
- Where it doesn't
- Agent installation is required on each protected server
- Free plan limits coverage to one server and monitor mode
- Focuses on exposure and authentication defense, not deep assessment
