Trustico® CaaS DV Single Site Information

Automate your website security with Trustico® CaaS DV, a Certificate as a Service (CaaS) SSL Certificate built for programmatic deployment. This Domain Validation (DV) SSL Certificate delivers API-driven management and rapid issuance for single domain protection.

Whether you are provisioning SSL Certificates through CI/CD pipelines, managing infrastructure as code, or integrating security into automated deployment workflows, Trustico® CaaS DV provides the programmatic control your team requires.

When you order a Trustico® CaaS DV SSL Certificate, simply provide your domain without the www prefix. Trustico® automatically adds the www version as an additional domain free of charge. For example, ordering yourdomain.com results in coverage for both yourdomain.com and www.yourdomain.com, so your ACME client can request SSL Certificates for both versions.

For domain types that would not normally include a www prefix, such as mail.yourdomain.com or ftp.yourdomain.com, the www version is not added automatically. You can request it to be added manually if needed. If you order www.yourdomain.com directly, that is the only domain that will be issued with no additional domain included.

Why Choose Certificate as a Service

Traditional SSL Certificate management requires manual steps at every stage, from generating a Certificate Signing Request (CSR) and completing validation to downloading files and installing them on your server. Certificate as a Service (CaaS) replaces this entire manual process with API-driven automation that handles ordering, validation, issuance, and reissuance programmatically.

When you purchase a Trustico® CaaS DV SSL Certificate, you are purchasing an SSL Certificate license for a set period. Throughout your license period, your ACME client automatically reissues 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 your domain 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. The extended license validity is recognized automatically, and your ACME client continues to obtain SSL Certificates as usual. There is no need to generate new External Account Binding (EAB) credentials, update your ACME client configuration, or make any changes to your server. Learn About License Extensions 🔗

Trustico® CaaS DV gives DevOps teams the ability to incorporate SSL Certificate provisioning directly into CI/CD pipelines, infrastructure as code configurations, and automated deployment systems. Real-time monitoring of SSL Certificate status, automated reissuance triggers, and dynamic management are all accessible through the API, allowing your team to streamline SSL Certificate deployment across your entire infrastructure without interrupting existing workflows.

How Automated SSL Certificate Management Works

Trustico® CaaS DV uses the Automated Certificate Management Environment (ACME) protocol to handle the SSL Certificate lifecycle programmatically. Your server communicates directly with the Certificate Authority (CA) through an ACME client, which manages domain verification, SSL Certificate issuance, and reissuance without any manual intervention.

The process begins when you install an ACME client on your server and authenticate using External Account Binding (EAB) credentials provided through your Trustico® account. The ACME client then proves domain ownership through either an HTTP-01 challenge or a DNS-01 challenge. Once the Certificate Authority (CA) verifies domain control, your SSL Certificate is issued and installed automatically.

Before expiration, the ACME client repeats the validation process and fetches a reissued SSL Certificate, ensuring continuous protection without downtime. Explore ACME Protocol Details 🔗

Supported ACME Clients and Server Environments

Trustico® CaaS DV works with all major ACME clients, giving you the flexibility to choose the tool that fits your existing infrastructure. Certbot is widely used on Linux systems running Apache or Nginx, while win-acme and Certify The Web provide native Windows support for Microsoft Internet Information Services (IIS). For containerized environments, cert-manager integrates directly with Kubernetes, and acme.sh offers a lightweight shell-based option suitable for scripted deployments.

Additional clients such as lego, dehydrated, and Posh-ACME provide further options for Go, shell, and PowerShell environments respectively.

These ACME clients support deployment across Apache, Nginx, Microsoft Internet Information Services (IIS), cPanel, Plesk, Docker, Kubernetes, Caddy, and all major cloud platforms. Regardless of your server environment, the automation workflow remains consistent : authenticate with External Account Binding (EAB) credentials, complete the domain challenge, and receive your SSL Certificate.

External Account Binding Credentials

External Account Binding (EAB) is the secure authentication mechanism that links your ACME client to the Certificate Authority (CA). When you set up your ACME client for the first time, you provide a Key Identifier and an HMAC Key that Trustico® generates through your account dashboard. These credentials verify that your ACME client is authorized to request SSL Certificates under your account.

Each set of External Account Binding (EAB) credentials can be managed independently, allowing you to maintain separate bindings for different servers, environments, or deployment pipelines. This separation provides clear tracking of which systems are requesting SSL Certificates and simplifies management across complex infrastructure. View Our EAB Credential Setup Guide 🔗

Instant Domain Validation

Trustico® CaaS DV is issued through automated Domain Validation (DV) that typically completes within minutes. The ACME client handles domain ownership verification automatically by responding to a challenge from the Certificate Authority (CA). With HTTP-01 validation, the client places a verification file on your web server that the Certificate Authority (CA) retrieves to confirm domain control.

With DNS-01 validation, the client creates a temporary Domain Name System (DNS) TXT record that serves as proof of ownership. DNS-01 validation is particularly useful for servers behind firewalls, internal networks, or environments where port 80 is not publicly accessible. Both methods are fully automated through the ACME client, requiring no manual file uploads or e-mail approvals. Learn About Domain Validation 🔗

Industry Standard Encryption

Trustico® CaaS DV uses 2048-bit RSA encryption paired with 256-bit symmetric encryption to secure data in transit between your server and your visitors. Full support for Transport Layer Security (TLS) 1.2 and Transport Layer Security (TLS) 1.3 ensures broad compatibility across modern browsers and devices.

SHA-256 hashing algorithms and Certificate Transparency logging provide additional layers of trust and accountability. Elliptic Curve Cryptography (ECC) key types are also supported for environments that benefit from smaller key sizes and faster handshakes. Compare Encryption Standards 🔗

Why Shorter SSL Certificate Validity Periods Make Automation Essential

The CA/Browser Forum has approved a phased reduction in maximum SSL Certificate validity periods. From March 2026, the maximum validity drops to 200 days. This reduces further to 100 days from March 2027, and eventually to just 47 days from March 2029. These changes mean that SSL Certificates will need to be replaced far more frequently than the current annual cycle that most organizations are accustomed to.

Without automation, each reissuance cycle requires manual Certificate Signing Request (CSR) generation, domain validation, SSL Certificate download, and server installation. At 47-day intervals, this creates a significant operational burden that grows with every domain you manage.

Certificate as a Service (CaaS) with ACME automation handles these reissuances programmatically, ensuring your SSL Certificates are always current without any manual effort. Trustico® CaaS DV is purpose-built for this new reality of shorter validity periods. Explore Traditional vs CaaS Comparison 🔗
