 certctl fills that gap. It's **CA-agnostic** — plug in any certificate authority: Let's Encrypt via ACME, Smallstep step-ca, HashiCorp Vault PKI, DigiCert CertCentral, your enterprise ADCS via sub-CA mode, or any custom CA through a shell script adapter. Run multiple issuers simultaneously for different certificate types.

Agents generate ECDSA P-256 private keys locally, create CSRs, and submit them to the control plane for signing — private keys never leave agent infrastructure. Agents also handle certificate deployment to target systems (NGINX, Apache httpd, HAProxy fully implemented; F5 BIG-IP, IIS interface only with V2 implementations planned) and report job status. They communicate with the control plane via HTTP and authenticate with API keys.

They communicate with the control plane via HTTP and authenticate with API keys.
 
 The agent runs two background loops: a heartbeat (every 60 seconds) to signal it's alive, and a work poll (every 30 seconds) to check for actionable jobs via `GET /api/v1/agents/{id}/work`. Jobs may be `AwaitingCSR` (agent needs to generate key + submit CSR) or `Deployment` (agent needs to deploy a certificate). Private keys are stored in `CERTCTL_KEY_DIR` (default `/var/lib/certctl/keys`) with 0600 permissions.

+
+The Sectigo connector integrates with Sectigo Certificate Manager's REST API for ordering and managing DV, OV, and EV certificates. Like DigiCert, it uses an async order model: submit an enrollment, receive an sslId, then poll for completion.
+
+**Configuration:**
+
+| Variable | Default | Description |

+| `CERTCTL_SECTIGO_CUSTOMER_URI` | — | Sectigo customer URI (organization identifier) |

+| `CERTCTL_SECTIGO_TERM` | `365` | Certificate validity in days |
+| `CERTCTL_SECTIGO_BASE_URL` | `https://cert-manager.com/api` | Sectigo API base URL |
+
+The connector submits certificate enrollments to Sectigo's `/ssl/v1/enroll` API. DV certificates may issue immediately; OV/EV certificates require validation (handled by Sectigo) and poll-based completion. The connector periodically checks enrollment status via `/ssl/v1/{sslId}` and downloads the PEM bundle via `/ssl/v1/collect/{sslId}/pem` when issued.
+
+**Authentication:** Three custom headers on every request — `customerUri`, `login`, and `password`.
+
+**Note:** CRL and OCSP are managed by Sectigo. certctl records revocations locally and notifies Sectigo via `/ssl/v1/revoke/{sslId}`.

+The Postfix/Dovecot connector is a dual-mode mail server TLS connector. It writes certificate, key, and chain files to configured paths and reloads the mail service. The `mode` field selects between Postfix MTA and Dovecot IMAP/POP3, which determines default file paths and reload commands.
+
+This connector pairs with certctl's S/MIME certificate support (email protection EKU, email SAN routing) for a complete email infrastructure story — TLS for transport encryption, S/MIME for end-to-end message signing and encryption.

 ### F5 BIG-IP (Interface Only)
 
 The F5 BIG-IP target connector interface is defined with the iControl REST flow mapped out, but the actual API calls are not yet implemented. F5 appliances can't run agents directly, so this connector uses the **proxy agent pattern**: a designated agent in the same network zone picks up F5 deployment jobs and calls the iControl REST API. The server assigns the work; the proxy agent executes it.

+# Deployment Examples
+
+Five turnkey docker-compose scenarios, each runnable in under 5 minutes. Pick the one closest to your setup.
+
+## Which Example Should I Use?
+
+| I need to... | Example | Issuer | Target |
+|--------------|---------|--------|--------|
+| Get Let's Encrypt certs for NGINX on a public server | [ACME + NGINX](#acme--nginx) | ACME (HTTP-01) | NGINX |
+| Issue wildcard certs without opening port 80 | [Wildcard DNS-01](#wildcard-dns-01) | ACME (DNS-01) | Any |
+| Run an internal CA for services behind a firewall | [Private CA + Traefik](#private-ca--traefik) | Local CA | Traefik |
+| Use Smallstep step-ca as my PKI backend | [step-ca + HAProxy](#step-ca--haproxy) | step-ca | HAProxy |
+| Manage both public and internal certs from one dashboard | [Multi-Issuer](#multi-issuer) | ACME + Local CA | Mixed |
+
+**Already using another tool?** See the migration sections below each example for Certbot, acme.sh, and cert-manager users.
+
+---
+
+## ACME + NGINX
+
+**Scenario:** You have one or more public-facing domains, NGINX as the reverse proxy, and want automated Let's Encrypt certificates with HTTP-01 challenges.
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent + NGINX, all on one Docker network. The agent generates keys locally (ECDSA P-256), submits CSRs to the server, receives signed certs from Let's Encrypt, and deploys them to NGINX with automatic reload.
+
+**Prerequisites:** A domain pointing to your server, ports 80 and 443 open, Docker Compose v20.10+.
+
+```bash
+cd examples/acme-nginx
+cp .env.example .env   # Edit with your domain and email
+docker compose up -d
+```
+
+The full walkthrough — including how HTTP-01 challenges work, adding multiple domains, switching to staging for testing, and a production checklist — is in the [example README](../examples/acme-nginx/acme-nginx.md).
+
+**Migrating from Certbot?** certctl discovers your existing `/etc/letsencrypt/live/` certificates automatically. You keep your ACME account, disable the Certbot cron, and certctl takes over renewal with centralized visibility and deployment verification. The step-by-step process is in [Migrating from Certbot](migrate-from-certbot.md).
+
+---
+
+## Wildcard DNS-01
+
+**Scenario:** You need wildcard certificates (`*.example.com`) or your servers aren't reachable from the internet (no port 80). DNS-01 validates ownership by creating a TXT record at your DNS provider.
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent. Includes a Cloudflare DNS hook script as a working reference — swap in your own DNS provider (Route53, Azure DNS, Google Cloud DNS, or any provider with an API).
+
+**Prerequisites:** A domain, API credentials for your DNS provider, Docker Compose.
+
+```bash
+cd examples/acme-wildcard-dns01
+cp .env.example .env   # Edit with domain, email, DNS provider credentials
+docker compose up -d
+```
+
+The full walkthrough — including DNS-PERSIST-01 (set a TXT record once, never touch DNS again on renewals), adapting scripts for other providers, and propagation troubleshooting — is in the [example README](../examples/acme-wildcard-dns01/acme-wildcard-dns01.md).
+
+**Migrating from acme.sh?** Your existing `dns_*` hook scripts are compatible with certctl's DNS-01 — they use the same pattern (shell scripts creating TXT records). The migration guide covers script adaptation, discovery of existing acme.sh certificates, and phasing out the acme.sh cron. See [Migrating from acme.sh](migrate-from-acmesh.md).
+
+---
+
+## Private CA + Traefik
+
+**Scenario:** Internal services that don't need public CA validation. You run your own certificate authority — either a self-signed root for development, or a subordinate CA chained to your enterprise root (e.g., Active Directory Certificate Services).
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent + Traefik. The Local CA issuer signs certificates directly. Traefik watches a cert directory and auto-reloads when new files appear.
+
+**Prerequisites:** Docker Compose. For sub-CA mode, you'll need a CA certificate and key signed by your enterprise root.
+
+```bash
+cd examples/private-ca-traefik
+docker compose up -d    # Self-signed mode (no .env needed for demo)
+```
+
+The full walkthrough — including sub-CA setup with `CERTCTL_CA_CERT_PATH` and `CERTCTL_CA_KEY_PATH`, creating certificates via the API, monitoring deployments, and production hardening — is in the [example README](../examples/private-ca-traefik/private-ca-traefik.md).
+
+---
+
+## step-ca + HAProxy
+
+**Scenario:** You use Smallstep's step-ca as your private PKI and want automated lifecycle management for certificates deployed to HAProxy load balancers.
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent + step-ca (with JWK provisioner) + HAProxy. certctl issues certs via step-ca's native `/sign` API, combines them into HAProxy's expected PEM format (cert + chain + key in one file), and reloads HAProxy.
+
+**Prerequisites:** Docker Compose.
+
+```bash
+cd examples/step-ca-haproxy
+docker compose up -d
+```
+
+The full walkthrough — including step-ca provisioner configuration, integrating with an existing step-ca instance, HAProxy PEM format details, and advanced features (approval workflows, policy-based renewal, multi-instance HAProxy) — is in the [example README](../examples/step-ca-haproxy/step-ca-haproxy.md).
+
+---
+
+## Multi-Issuer
+
+**Scenario:** You manage both public-facing services (needing Let's Encrypt or another public CA) and internal services (using a private CA) and want a single dashboard for everything.
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent configured with both an ACME issuer and a Local CA issuer. Demonstrates issuer assignment via profiles — public services get ACME certs, internal services get Local CA certs, all visible in one inventory.
+
+**Prerequisites:** Docker Compose. For real ACME certs, a public domain and port 80 access.
+
+```bash
+cd examples/multi-issuer
+docker compose up -d
+```
+
+The full walkthrough — including profile-based issuer assignment, testing with ACME staging, Local CA enterprise sub-CA mode, and scaling beyond Docker Compose — is in the [example README](../examples/multi-issuer/multi-issuer.md).
+
+**Using cert-manager for Kubernetes?** certctl complements cert-manager — cert-manager handles in-cluster certs, certctl handles everything outside: VMs, bare metal, network appliances, Windows servers. They can share the same CA (ACME, step-ca, Vault PKI). See [certctl for cert-manager Users](certctl-for-cert-manager-users.md).
+
+---
+
+## Beyond These Examples
+
+These 5 scenarios cover the most common deployment patterns, but certctl supports 7 issuer backends and 10 target connectors. Once you have the basics running, you can mix and match:
+
+**Issuers:** ACME (Let's Encrypt, ZeroSSL, Buypass, Google Trust Services), Local CA (self-signed or sub-CA), step-ca, Vault PKI, DigiCert CertCentral, OpenSSL/Custom CA script, Sectigo (coming soon).
+
+**Targets:** NGINX, Apache, HAProxy, Traefik, Caddy, Envoy, IIS (local PowerShell or WinRM proxy), Postfix, Dovecot, F5 BIG-IP (coming soon).
+
+See [Connector Reference](connectors.md) for configuration details on every issuer and target.

 # Why certctl?
 
-Certificate management is broken at every scale between "one domain on Let's Encrypt" and "Fortune 500 budget for Venafi."
+Certificate management is broken at every scale between "one domain on Let's Encrypt" and "Fortune 500 budget for Venafi." certctl fills that gap: a self-hosted platform that automates the entire certificate lifecycle, works with any CA, deploys to any server, and keeps private keys on your infrastructure. It's free, source-available, and you own everything.
 
-If you run a personal blog, Certbot works fine. If your company spends $200K/year on Keyfactor, you're covered. But if you're an ops engineer managing 20-500 certificates across NGINX, Apache, HAProxy, and maybe a private CA — the tools available today either don't do enough or cost too much.
+## The Math That Forces the Decision
 
-certctl fills that gap.
+The CA/Browser Forum passed [Ballot SC-081v3](https://cabforum.org/2025/04/11/ballot-sc081v3-introduce-schedule-of-reducing-validity-and-data-reuse-periods/) in April 2025, mandating a phased reduction in TLS certificate lifetimes: **200 days** as of March 2026, **100 days** by March 2027, and **47 days** by March 2029.
 
-## The Problem
+At 47-day lifespans, a team managing 100 certificates is processing **7+ renewals per week**, every week, forever. At 200 certificates, it's two per day. Manual processes, calendar reminders, and certbot cron jobs don't scale to this — a single missed renewal becomes a production outage at 3 AM. Certificate lifecycle automation is no longer optional; the only question is what tool runs it.
 
-The CA/Browser Forum passed [Ballot SC-081v3](https://cabforum.org/2025/04/11/ballot-sc081v3-introduce-schedule-of-reducing-validity-and-data-reuse-periods/) in April 2025, mandating a phased reduction in TLS certificate lifetimes: 200 days as of March 2026, 100 days by March 2027, and 47 days by March 2029. That means every organization needs automated certificate renewal — not eventually, but now.
+## The Landscape Today
 
-The existing options for automation are:
+If you're evaluating your options, here's what you'll find:
 
-- **ACME clients** (Certbot, Lego, CertWarden): Handle issuance and renewal for ACME-compatible CAs, but don't manage deployment to target servers, don't provide inventory visibility, don't support non-ACME CAs, and don't offer audit trails or policy enforcement.
-- **Kubernetes-native** (cert-manager): Works well inside Kubernetes, but if your infrastructure includes bare-metal servers, VMs, or network appliances alongside Kubernetes, you need a separate solution for everything cert-manager can't reach.
-- **Commercial SaaS** (CertKit, Sectigo CLM): Handle more of the lifecycle but are proprietary, cloud-dependent, and priced per certificate — costs scale linearly with your infrastructure.
-- **Enterprise platforms** (Venafi, Keyfactor, AppViewX): Comprehensive but start at $75K/year and require dedicated teams to operate.
+**ACME clients** (certbot, lego, acme.sh) handle issuance and renewal for Let's Encrypt and similar CAs, but they don't deploy to target servers, don't track inventory, don't support private CAs, and give you no audit trail or policy enforcement. You end up writing glue scripts and hoping they don't break.
+
+**Kubernetes-native tools** (cert-manager) work well inside the cluster, but most organizations run mixed infrastructure — NGINX on VMs, HAProxy at the edge, IIS on Windows, maybe an F5. You need a separate solution for everything outside Kubernetes.
+
+**Commercial SaaS platforms** handle more of the lifecycle but are proprietary, cloud-dependent, and priced per certificate. At 100 certs and 20 agents, SaaS pricing runs $3,000-5,000/year and scales linearly. You're paying rent on your own infrastructure's security.
+
+**Enterprise platforms** (Venafi, Keyfactor, AppViewX) are comprehensive but start at $75K/year and require dedicated teams to operate. If you have a 50-server environment, the licensing costs more than the servers.
 
 ## What certctl Does Differently
 
-certctl is a self-hosted certificate lifecycle platform. It handles issuance, renewal, deployment, revocation, discovery, and monitoring — with three design decisions that no other tool at any price point combines:

+Every connector implements the same interface. Running multiple CAs in parallel — Let's Encrypt for public certs, Vault for internal services, your enterprise CA for legacy systems — is configuration, not code.
 
 ### 3. Post-Deployment Verification
 
-Every other tool in this space stops at "the deployment command succeeded." certctl goes further: after deploying a certificate to a target, the agent connects back to the target's TLS endpoint and verifies the served certificate matches what was deployed, using SHA-256 fingerprint comparison.

+A reload command can exit 0 while the certificate doesn't take effect — wrong virtual host, stale cache, config that validates but doesn't apply. certctl catches this automatically.
+
+## What Else Ships Free
+
+The three differentiators above get the headlines, but the feature surface is wider than most paid platforms:
+
+**10 deployment targets** — NGINX, Apache, HAProxy, Traefik, Caddy, Envoy, IIS (local PowerShell + remote WinRM), Postfix, and Dovecot. All use a pluggable connector model. The control plane never initiates outbound connections — agents poll for work, meaning certctl works behind firewalls, across network zones, and in air-gapped environments.
+
+**Network certificate discovery** — active TLS scanning of CIDR ranges finds certificates you didn't know existed. Agents also scan local filesystems for PEM/DER files. Everything feeds into a triage workflow where you claim, dismiss, or import discovered certs into management.
+
+**Immutable audit trail** — every API call recorded (method, path, actor, body hash, status, latency). Every certificate lifecycle event tracked. Append-only, no update or delete. Mapped to SOC 2, PCI-DSS 4.0, and NIST SP 800-57 compliance frameworks with published evidence guides.
+
+**Policy engine** — 5 rule types (allowed issuers, allowed domains, required metadata, allowed environments, renewal lead time) with violation tracking and severity levels.
+
+**PKI compliance** — DER-encoded X.509 CRL signed by issuing CA, embedded OCSP responder, RFC 5280 revocation with all reason codes, short-lived certificate exemption.
+

 ## How certctl Compares
 
-### vs. CertKit
+### vs. ACME Clients
 
-Closest competitor architecturally — agent-based, private key isolation (Keystore), multi-platform. certctl leads on issuer coverage (ACME + step-ca + Local CA + OpenSSL + EST vs. ACME-only), PKI compliance (CRL, OCSP, RFC 5280 revocation, immutable audit trail — all missing from CertKit today), policy engine (5 rule types vs. none), and network discovery (CIDR TLS scanning vs. none). certctl is source-available (BSL 1.1 → Apache 2.0) with no cert limit; CertKit is proprietary SaaS with a 3-cert free tier. Where CertKit leads: more deployment targets today (adds LiteSpeed, IIS, auto-detection), Windows support, Kubernetes, and polished SaaS onboarding.
+ACME clients solve one slice of the problem — issuance and renewal from ACME CAs. certctl replaces the ACME client, adds 6 more CA integrations, deploys the cert to the right server, verifies it's live, tracks it in an inventory, alerts on expiry, logs everything to an audit trail, and enforces policy. If you're currently running certbot behind a cron job and a prayer, certctl replaces all of it.
 
-### vs. KeyTalk
+### vs. Agent-Based SaaS
 
-Commercial (proprietary) PKI platform from a Dutch company — on-prem appliance, cloud, or managed service. Broader cert type coverage (TLS, S/MIME, device auth, VPN) and DigiCert + SCEP integrations. No public documentation on policy engine, API surface, or audit capabilities. No free tier, no public pricing. certctl trades breadth of cert types for full transparency — source-available, public API spec, free community edition with no limits.
+The closest architectural competitors use the same agent model — local key generation, CSR submission, push-based deployment. Where certctl differs: it supports 7 issuer types (not just ACME), provides CRL/OCSP/revocation infrastructure (not just issuance), includes a policy engine and network discovery, and is source-available with no certificate limit. SaaS alternatives are typically proprietary, priced per certificate ($2+/cert/month), and cap their free tiers at 3-5 certificates. certctl is free for any number of certificates, forever.
 
-### vs. Enterprise Platforms (Venafi, Keyfactor)
+### vs. Commercial PKI Platforms
 
-Comprehensive solutions with decades of features — at $75K-$250K+/yr. certctl targets organizations that need 80% of those capabilities at 1% of the cost. The trade-off: no SSO/RBAC yet (coming in certctl Pro), no F5/IIS target connectors yet, no SLA-backed support.
+On-prem or hosted commercial platforms offer broader cert type coverage (VPN certs, device auth, SCEP) and deeper CA integrations. The trade-off: no free tier, opaque pricing (often €13K+/year for 1,500 certs), proprietary codebases, and no public API documentation. certctl trades breadth of exotic cert types for full transparency — source-available code, 97-operation OpenAPI spec, and a free community edition with no artificial limits.
 
-## Getting Started
+### vs. Enterprise Platforms
+
+Venafi and Keyfactor offer decades of features at $75K-$250K+/year. certctl targets organizations that need 80% of those capabilities at a fraction of the cost. What certctl doesn't have yet: SSO/RBAC (coming in certctl Pro), vendor SLA-backed support. What certctl does have that enterprise platforms don't: an MCP server for AI-assisted management, ACME ARI (RFC 9702) for CA-directed renewal timing, and a deployment model that works in 5 minutes instead of 5 months.
+
+## Who Should Look Elsewhere
+
+certctl isn't the right tool for everyone:
+
+- **Single-domain sites** — if you have one certificate on one server, certbot is fine. certctl is designed for managing tens to hundreds of certificates across multiple servers and CAs.
+- **Pure Kubernetes environments** — if every workload runs in-cluster and you're happy with cert-manager, there's no reason to add another tool. certctl shines when your infrastructure extends beyond Kubernetes.
+- **Organizations that need a vendor SLA today** — certctl is source-available software maintained by a small team. If you need contractual uptime guarantees and a support hotline, an enterprise platform is the right choice (for now).
