TigerTrust vs Google Certificate Manager

Beyond GCP-only certificates.

Google Certificate Manager does exactly what its name says: it manages TLS certificates for Google-fronted workloads on GCP load balancers. Combined with GCP Certificate Authority Service, it covers a slice of the PKI story — the GCP slice. TigerTrust delivers full multi-cloud certificate lifecycle management, private-CA workflows, and machine-identity depth across your entire estate.

Why teams add TigerTrust

GCP-native, but not GCP-only.

Google Certificate Manager is well-integrated for GCP-fronted workloads. Teams add TigerTrust when the estate stretches beyond GCP or when they need lifecycle discipline across every certificate.

Cross-cloud coverage
Discovery and lifecycle across GCP, AWS, Azure, on-prem load balancers, and Kubernetes clusters across every environment.
Discovery beyond GCP
Certificate Manager sees Google-fronted workloads. TigerTrust discovers certificates on GKE workloads, third-party appliances, SaaS callbacks, and on-prem endpoints.
Unified CA layer
Google-managed certs, GCP CA Service, and any other CA in the estate — DigiCert, Sectigo, private roots, ADCS, Vault — under one policy plane.
Alerting and owner routing
Multi-channel notifications with owner assignment and escalation. No Cloud Monitoring + PubSub DIY plumbing required.
The move above

What changes when GCP is one cloud of many.

Without Google
  • Coverage scoped to GCP-managed certs on Google load balancers
  • GCP CA Service is a separate product — not the same lifecycle plane
  • No discovery of certificates outside the GCP surface
  • Alerts require Cloud Monitoring + PubSub plumbing
  • No prebuilt compliance evidence pack (SOC 2, PCI, HIPAA)
With TigerTrust
  • Every certificate — GCP or not — in one inventory
  • Google-managed, CA Service, and third-party CAs on one platform
  • Discovery across GCP, AWS, Azure, and on-prem
  • Multi-channel alerts with owner routing built in
  • Prebuilt compliance evidence packs, audit-ready exports

Capability comparison, head to head.

Google Certificate Manager is well-designed for its scope. Here is where the offerings overlap and where the scope differs.

Add TigerTrust above GCP.

You do not have to leave Google Certificate Manager. Most GCP-first teams keep it in place and add TigerTrust for the CLM layer.

01

Connect GCP

TigerTrust discovers Google-managed certs, CA Service-issued certs, and certificates deployed on load balancers, GKE, Cloud Run, and Apigee.

02

Extend discovery

Add AWS, Azure, on-prem load balancers, and Kubernetes clusters across the estate. Every certificate lands in one inventory.

03

Keep GCP as the front-door issuer

Google-managed and CA Service certs remain authoritative for their targets. TigerTrust adds visibility, ownership, and reporting around them.

04

Wire up policy and compliance

Assign owners, connect alerting channels, enable the compliance evidence pack, and set cross-CA policy for issuance routing.

Frequently asked questions

What does Google Certificate Manager actually cover?

It is scoped to certificates for GCP-fronted workloads — primarily Google-managed public TLS certificates attached to Global External Application Load Balancers, Cloud CDN, and related services. It handles issuance and renewal for those managed certs and lets you import self-managed certs for use with the same targets. It is not a general-purpose CLM.

How is it different from GCP Certificate Authority Service?

They are separate products. CA Service is Google's private CA (comparable to AWS Private CA); Certificate Manager is for provisioning TLS certs to Google load balancers. Neither on its own gives you cross-cloud discovery, lifecycle for non-GCP endpoints, or a compliance evidence pack.

We are fully on GCP. Do we need TigerTrust?

If every certificate you care about is a Google-managed cert on a Google load balancer, you may be fine with Certificate Manager alone. Most GCP-first teams still end up with some workload certs from CA Service, some shadow OpenSSL certs, and often an on-prem or SaaS footprint they did not plan for. TigerTrust unifies all of that.

Can TigerTrust manage the GCP-managed certificates too?

Yes — we discover and inventory them so they appear in the same view as everything else, and we watch renewal state so a GCP outage or misconfiguration on a managed cert still surfaces as an alert with an owner.

What about workload identity with SPIFFE/SPIRE on GKE?

That flow can continue unchanged. TigerTrust complements workload identity systems by covering the wider certificate estate — load balancers, third-party appliances, IoT devices, code signing, and cross-cloud endpoints that SPIFFE is not designed for.

Kept GCP Certificate Manager for storefronts, added cross-cloud coverage for everything else.

Google Certificate Manager was perfect for our load balancers. It could not tell us about the certs on our GKE workloads, our AWS DR site, or our supplier appliances.
