Executive Summary

Silent TLS certificate expirations are a persistent, low-noise failure mode that leads to customer-facing outages, degraded telemetry, and expensive incident response. Operations, SRE and security teams running cloud-native fleets—including the 1,000,000 companies captured in our $6.0B addressable market—struggle with rapidly rotating certificates (e.g., 90‑day ACME certs), ephemeral workloads on Kubernetes, and certificate sources spread across cloud providers and secrets stores. You could build a Prometheus-native certificate-exporter that discovers certs across ingress controllers, Kubernetes secrets, cloud certificate stores (ACM, Key Vault, ACM), and ACME/Vault workflows, and exposes expiration and validation metrics with rich labels for alerting and dashboards. Ship an open‑source core (lightweight, Helm-ready) plus an enterprise add-on for multi‑tenant inventory, compliance-grade audit logs, RBAC and managed integrations, so teams get immediate metric-based alerts in their existing Prometheus/Grafana stacks without a heavy new control plane. This is an attractive moment because observability-first ops and broad Prometheus/Grafana adoption make metric-based remediation the path of least resistance, and security/supply-chain scrutiny raises demand for auditable certificate tooling; a $6.0B TAM at ~$6,000 ACV per company shows commercial plausibility for a focused add-on. To stand out, prioritize being Prometheus-first, Kubernetes-native discovery, and privacy-friendly operation (no mandatory central collection), plus turnkey dashboards and alert rules for fast time-to-value. Be honest about the challenges: competition is medium, integrations across many certificate vendors and enterprise procurement cycles are nontrivial, and building trust with security teams requires strong auditability and predictable maintenance.

Market Opportunity

Prevent silent TLS certificate outages by exporting expirations to Prometheus targets a $6.0B = 1,000,000 companies x $6,000 ACV (global addressable market for certificate monitoring/observability add-ons and lightweight cert management) total addressable market with medium saturation and a year-over-year growth rate of 15-20%.

Key trends driving demand: Cloud-native adoption -- more apps run on Kubernetes, increasing ephemeral certs and the need for scalable monitoring.; Observability-first operations -- teams standardize on Prometheus/Grafana, making metric-based alerts the preferred remediation path.; Security & supply-chain focus -- audits and SBOMs push orgs to adopt secure, auditable tooling with reproducible builds.; Automation of cert lifecycle -- more automation increases issuance frequency and chances of unnoticed expiry without monitoring..

Key competitors include Venafi, Keyfactor, Smallstep (step-ca), HashiCorp Vault, Open-source exporters & workarounds (prometheus-blackbox, custom scripts, cert-manager metrics).
