Why Choose Certificate as a Service for Wildcard Protection

Managing Wildcard SSL Certificates manually becomes increasingly difficult as your subdomain infrastructure grows. Every time a Wildcard SSL Certificate approaches expiration, someone on your team must generate a new Certificate Signing Request (CSR), complete domain validation, download the SSL Certificate files, and install them across every server that hosts your subdomains. Certificate as a Service (CaaS) automates this entire workflow through API-driven management, removing the manual burden from your team.

When you purchase a Trustico® CaaS DV + Wildcard SSL Certificate, you are purchasing an SSL Certificate license for a set period. Throughout your license period, your ACME client automatically reissues Wildcard SSL Certificates as they approach expiration, extending the expiration date of your installed SSL Certificate based on your available license validity. This means you purchase once and every subdomain stays protected continuously for the duration of your license.

When your license period approaches its end, you can extend or renew it without any reinstallation or reconfiguration across any of your servers. The extended license validity is recognized automatically, and your ACME client continues to obtain Wildcard SSL Certificates as usual.

There is no need to update External Account Binding (EAB) credentials, reconfigure Domain Name System (DNS) plugins, or modify any part of your existing automation. Learn About License Extensions 🔗

Trustico® CaaS DV + Wildcard provides full API access to ordering, validation, and deployment for your Wildcard SSL Certificate. DevOps teams can embed Wildcard SSL Certificate provisioning directly into CI/CD pipelines, infrastructure as code workflows, and automated scaling systems. The API provides real-time SSL Certificate status monitoring, automated reissuance triggers, and dynamic subdomain protection across your entire infrastructure. Discover Certificate as a Service 🔗

Full Wildcard Subdomain Coverage

Trustico® CaaS DV + Wildcard protects unlimited subdomains under *.yourdomain.com with a single SSL Certificate, and also secures the root domain yourdomain.com itself. This eliminates the need to manage individual SSL Certificates for each subdomain while ensuring consistent encryption across your entire domain infrastructure. The Wildcard SSL Certificate automatically covers all existing subdomains and any subdomains you create in the future.

When you launch a new service on app.yourdomain.com, staging.yourdomain.com, or api.yourdomain.com, it is protected immediately without any additional SSL Certificate provisioning. This automatic coverage is essential for dynamic environments where new subdomains are created as part of deployment pipelines, feature branches, or customer onboarding processes. Understand Wildcard Benefits 🔗

How Wildcard Automation Works with ACME

Trustico® CaaS DV + Wildcard uses the Automated Certificate Management Environment (ACME) protocol to automate your Wildcard SSL Certificate lifecycle. An ACME client installed on your server handles domain verification, SSL Certificate issuance, installation, and reissuance without any manual steps. The client authenticates with the Certificate Authority (CA) using External Account Binding (EAB) credentials generated through your Trustico® account.

For Wildcard SSL Certificates, the ACME protocol requires DNS-01 validation, which involves creating a temporary Domain Name System (DNS) TXT record to prove ownership of the base domain. Many ACME clients support automated Domain Name System (DNS) record management through API integrations with popular Domain Name System (DNS) providers including Cloudflare, AWS Route 53, Google Cloud DNS, and DigitalOcean DNS.

This means the entire Wildcard SSL Certificate lifecycle, from initial issuance to every subsequent reissuance, can run without any human involvement. Explore ACME Protocol Details 🔗

Supported ACME Clients for Wildcard Deployment

Trustico® CaaS DV + Wildcard works with all major ACME clients that support DNS-01 challenges. Certbot is the most widely deployed option and supports Wildcard SSL Certificates through its DNS plugins for popular hosting providers.

The acme.sh client offers extensive Domain Name System (DNS) API integrations and is well suited to scripted and cron-based reissuance workflows. For Kubernetes environments, cert-manager automates Wildcard SSL Certificate issuance and reissuance as a native cluster resource.

Windows environments are supported through win-acme and Certify The Web, both of which handle Wildcard SSL Certificates for Microsoft Internet Information Services (IIS). Additional clients such as lego (Go-based), dehydrated (shell-based), and Posh-ACME (PowerShell) round out the options for specialized environments.

Regardless of which client you choose, the Wildcard automation workflow follows the same pattern : authenticate with External Account Binding (EAB) credentials, complete the DNS-01 challenge, and receive your Wildcard SSL Certificate. Find Out More About Supported ACME Clients 🔗

External Account Binding for Wildcard SSL Certificates

External Account Binding (EAB) provides the secure link between your ACME client and the Certificate Authority (CA) that issues your Wildcard SSL Certificate. Trustico® generates a Key Identifier and an HMAC Key through your account dashboard, and you supply these credentials when configuring your ACME client for the first time. This one-time authentication step authorizes your client to request and reissue Wildcard SSL Certificates under your account.

You can generate separate External Account Binding (EAB) credentials for different servers, environments, or teams. This separation is particularly valuable for Wildcard deployments where the same *.yourdomain.com SSL Certificate might be managed by different ACME clients across production, staging, and development environments.

Domain Validation for Wildcard SSL Certificates

Trustico® CaaS DV + Wildcard is issued through automated Domain Validation (DV) that validates *.yourdomain.com once to cover all current and future subdomains. Wildcard SSL Certificates require DNS-01 validation, where your ACME client creates a temporary TXT record in your domain's Domain Name System (DNS) zone. The Certificate Authority (CA) checks this record to confirm you control the base domain, and upon successful verification, issues your Wildcard SSL Certificate.

Because DNS-01 validation does not require your web server to be publicly accessible, it works for servers behind firewalls, internal networks, and staging environments that are not exposed to the internet. The ACME client automates the entire process, including Domain Name System (DNS) record creation and cleanup. Learn About Validation Methods 🔗

Preparing for Shorter SSL Certificate Validity Periods

The CA/Browser Forum has approved progressive reductions in maximum SSL Certificate validity. Beginning in March 2026, the maximum drops to 200 days, then to 100 days from March 2027, and ultimately to just 47 days from March 2029. For Wildcard SSL Certificates that protect multiple subdomains across potentially dozens of servers, this creates a reissuance frequency that is impractical to manage manually.

Trustico® CaaS DV + Wildcard with ACME automation ensures your Wildcard SSL Certificate is automatically reissued before every expiration date without any team involvement. At 47-day intervals, a Wildcard SSL Certificate protecting your entire subdomain infrastructure would need to be reissued roughly eight times per year.

With automation, each reissuance is handled silently by your ACME client. Without it, each cycle demands manual Certificate Signing Request (CSR) generation, domain validation, and reinstallation across every server. Explore Traditional vs CaaS Comparison 🔗

Industry Standard Encryption

Trustico® CaaS DV + Wildcard provides 2048-bit RSA encryption with 256-bit symmetric encryption applied consistently across every subdomain. Full support for Transport Layer Security (TLS) 1.2 and Transport Layer Security (TLS) 1.3 ensures broad compatibility with modern browsers and devices.

Every secured subdomain benefits from perfect forward secrecy, SHA-256 hashing algorithms, and Certificate Transparency logging. Elliptic Curve Cryptography (ECC) key types are also supported for environments that benefit from faster cryptographic operations. Compare Encryption Technologies 🔗
