Why Automated SSL Management Matters
For developers and IT teams managing multiple domains, manual SSL certificate handling poses two critical challenges: operational complexity and renewal risks.
- Complex Workflows: Manually applying, deploying, and renewing certificates across servers consumes valuable time.
- Expiration Risks: Free certificates (e.g., Let’s Encrypt) expire every 90 days. Missed renewals can cause service outages.
Certimate solves these challenges through localized automation, ensuring seamless certificate lifecycle management.
Key Advantages of Certimate
1. Self-Hosted Deployment for Data Control
Run Certimate as a binary, Docker container, or compiled from source. All certificate data remains on your infrastructure, eliminating third-party dependencies and security risks.
2. End-to-End Automation
Certimate automates certificate issuance (via ACME protocols), format conversion (PEM, PFX, JKS), and deployment to 70+ targets (Kubernetes, CDNs, load balancers). Renewals begin 30 days before expiration, ensuring zero downtime.
3. Broad Compatibility
- Certificate Types: Single-domain, multi-domain, wildcard (RSA/ECC encryption).
- Provider Support: Integrates with 20+ DNS providers (Cloudflare, Alibaba Cloud) and platforms like AWS, Tencent Cloud.

Advanced Features Explained
1. Multi-CA Flexibility
Choose from Let’s Encrypt, ZeroSSL, Google Trust Services, and other CAs. Balance cost (free vs. commercial) and trust chain requirements.
2. Smart Notifications
Configure alerts for:
- Events: Issuance success, renewal failures, expiration warnings.
- Channels: Email, Slack (via Webhook), DingTalk, Feishu, or custom integrations.
3. Enterprise-Grade Security
- Audit Logs: Track all certificate operations with timestamps and user IDs.
- Role-Based Access: Assign permissions as Admin, Operator, or Viewer for team collaboration.
Real-World Use Cases
Case 1: Multi-Domain Management
An e-commerce platform manages 10 domains. Certimate issues a wildcard certificate once, deploying HTTPS across all subdomains (e.g., shop.example.com, blog.example.com).
Case 2: Hybrid Cloud Deployment
Sync certificates across AWS, Alibaba Cloud, and on-prem servers. Certimate updates Kubernetes Ingress and cloud load balancers simultaneously via plugins.
Case 3: Ephemeral Certificates for Staging
Generate short-term certificates for dev.example.com with auto-cleanup, avoiding configuration clutter in testing environments.
FAQs
Q1: Does Certimate work in air-gapped networks?
Yes. Configure internal DNS servers for DNS-01 challenges without public internet access.
Q2: How to migrate existing certificates?
Use the “Import Certificate” feature to upload PEM files. Certimate auto-detects expiration dates and schedules renewals.
Q3: Is SM2/SM4 (Chinese cryptography) supported?
Not natively, but extensible via custom CA configurations.
