Building an Enterprise Security Platform: Wazuh on Kubernetes with MCP Integration

In today’s threat landscape, comprehensive security monitoring across hybrid infrastructure isn’t optional—it’s essential. This article details our journey implementing a production-grade Wazuh security platform on Kubernetes (k3s), complete with a custom Model Context Protocol (MCP) server for AI-driven security operations.

What we built:

• Enterprise SIEM platform on self-hosted Kubernetes
• Comprehensive security monitoring across k8s, Proxmox VMs, Cloudflare WAF, GitHub, and UniFi networks
• Custom MCP server with 25+ security tools
• High-availability architecture with KEDA autoscaling
• Annual cost savings: $6,000-$12,000 vs SaaS alternatives

Infrastructure protected:

• k3s cluster (4 nodes, 28 cores, 56Gi RAM)
• Proxmox virtualization platform (multiple VMs)
• Cloudflare edge security (WAF events)
• GitHub repositories (security alerts)
• UniFi network infrastructure
