Private CA Monitoring

Internal certificates expire too, and external monitoring services can't reach them.

Organizations use private certificate authorities to issue certificates for internal services, development environments, and private networks. These certificates expire just like public ones, but external monitoring services have no way to reach them. Without a dedicated solution, expiration goes unnoticed until something breaks.

On-Premise Monitoring Agents

Deploy a lightweight monitoring agent inside your network. It checks certificate expiration and chain validity, then reports results to the Generator Labs platform over outbound HTTPS. Private keys never leave your network.

How It Works

Secure monitoring architecture for internal certificate infrastructure.

The monitoring agent checks internal service certificates and reports certificate data to the platform via outbound HTTPS. Private keys remain secure within your network. Alerts are delivered through email, Slack, PagerDuty, webhooks, and other channels.

Step 1

Deploy & Configure Agent

Deploy agent as Docker container within your network and configure internal hosts to monitor. Checks any reachable endpoint: websites, APIs, mail servers, databases, or custom ports.

Step 2

Agent Monitors Certificates

Agent connects to configured hosts, retrieves SSL/TLS certificates, checks expiration dates, and validates certificate chains including private CAs.

Step 3

Get Timely Alerts

Agent reports certificate data via encrypted connection. Platform generates alerts based on configured thresholds. Integrate with incident management via webhooks and API callbacks.

Common Use Cases

Anywhere you run internal TLS, the agent can monitor it.

Internal Corporate Services

Monitor certificates for intranet sites, internal APIs, employee portals, and business applications.

Development Environments

Track certificates in staging, testing, and development environments so expired certificates don't disrupt non-production workflows.

IoT and Embedded Devices

Monitor certificates on internal IoT devices, industrial equipment, and embedded systems. Track devices that can't be reconfigured after certificate expiration.

Database Connections

Track TLS certificates on encrypted database connections before an expiration silently breaks application connectivity.

Security Appliances

Monitor certificates on firewalls, VPN gateways, load balancers, and security devices. These systems use internal certificates for management interfaces and encrypted tunnels.

Microservices Architecture

Track service mesh certificates and mTLS configurations. Monitor certificate rotation in Kubernetes clusters and containerized environments.

Frequently Asked Questions

Common questions about monitoring agents.

What are monitoring agents?

Monitoring agents are lightweight Docker containers that run inside your network, connect to internal hosts, retrieve their certificates, and report validation results back to the Generator Labs platform over outbound HTTPS. No inbound firewall rules are required. Full documentation is available on GitHub and in the Certificate Monitoring docs.

How do I deploy monitoring agents?

Agents run as Docker containers on Linux, Windows, or macOS. See the installation guide on GitHub.

Is there an additional cost for monitoring agents?

No. Monitoring agents are included at no additional cost.

How can I know the agent code is secure?

The monitoring agent is open source and available on GitHub. Anyone can review the code, audit the implementation, and submit improvement requests. This transparency ensures the security and integrity of the monitoring agent.
