Internal SSL Monitoring for Private Networks and Internal PKI

Use Case

Monitor internal certificates and TLS endpoints that public scanners can’t reach.

Certhelm combines cloud-based visibility for public services with LAN collectors for private-network SSL/TLS monitoring, so internal APIs, load balancers, VPN gateways, and internal PKI endpoints do not fall out of view.

See Collector Pricing Learn About LAN Collectors

Cover private hostnames, internal IPs, branch services, and internal load balancers
Track internal PKI certificates that never appear on public internet scans
Keep customer-owned visibility for network zones where external tools cannot see enough
Use the same workspace for public and internal certificate health

Where Public Checks Fall Short

Internal services still carry certificate risk even when the internet cannot see them.

Private hostnames and RFC1918-addressed systems are invisible to public scanners
Internal PKI environments still expire, drift, and break client trust
Teams need certificate observations from inside the network boundary
Operational ownership is often spread across network, platform, and application teams

Why Certhelm Fits

LAN collectors extend the product instead of creating a separate monitoring silo.

Cloud checks cover public services while collectors cover internal ones
Customer teams keep one shared model for assets, alerts, and certificate workflows
Delivery settings stay customer-scoped, which matters in private environments
Growth paths align with how much internal coverage you actually need

Visibility layers

Combine public internet checks and LAN collector observations in one workspace.

Ownership model

Keep internal and public certificate health tied to the same customer account.

Private paths

Scale from one internal segment to broader branch and datacenter coverage.

Related Paths

Pair internal visibility with adjacent use cases.

LAN collector monitoring for branch, datacenter, and segmented network coverage
SSL certificate monitoring for public and private expiry risk tracking
Website reachability monitoring when certificate and availability signals belong together

Next Step

Start public, then add collectors where internal visibility matters.

You do not need to deploy everywhere on day one. Start with the services that cannot be seen from outside your network, then expand collector coverage as your operating model matures.
