Wildcard SSL Certificate — One Certificate for Unlimited Subdomains

A wildcard SSL certificate is issued for *.yourdomain.com, where the asterisk matches any single-level subdomain. This means one certificate simultaneously secures www.yourdomain.com, mail.yourdomain.com, shop.yourdomain.com, api.yourdomain.com, and any other subdomain you create — without needing to reissue or reconfigure the certificate.

The wildcard covers subdomains that exist now and subdomains you create in the future. When you spin up a new staging environment at staging.yourdomain.com or add a customer portal at portal.yourdomain.com, the existing wildcard certificate automatically applies. There is no additional cost and no additional setup required.

AnubizHost wildcard certificates use the same industry-standard 256-bit encryption as single-domain certificates. Every subdomain benefits from full encryption, browser trust, and the padlock indicator. The only difference is scope — instead of protecting one hostname, you protect an entire level of your domain hierarchy.

If you run five subdomains with individual DV certificates at $9 each, you spend $45 per year and manage five separate certificates with five different expiration dates. A single wildcard certificate at $49 per year costs only marginally more while eliminating four management headaches — and it covers every additional subdomain you add at no extra cost.

The savings compound as your infrastructure grows. Organizations running ten, twenty, or fifty subdomains save hundreds of dollars annually compared to individual certificates. More importantly, they eliminate the operational risk of forgetting to renew one certificate in a large portfolio and having a subdomain suddenly display security warnings.

AnubizHost offers multi-year wildcard certificates with increasing discounts for longer terms. A 3-year wildcard brings the annual cost below $40, making it the most economical approach for any website using more than three subdomains. Combined with our auto-renewal, your entire subdomain infrastructure stays encrypted without manual intervention.

Modern development workflows rely on multiple environments — dev.yourdomain.com, staging.yourdomain.com, qa.yourdomain.com, and preview.yourdomain.com. Without SSL, these environments trigger browser warnings that interfere with testing and make it impossible to accurately reproduce production behavior. A wildcard certificate solves this by encrypting every environment automatically.

Many web applications behave differently over HTTP versus HTTPS. Secure cookies, service workers, geolocation APIs, and camera/microphone access all require HTTPS. Testing these features on an unencrypted staging server gives misleading results. A wildcard SSL ensures your development and staging environments mirror production security settings exactly.

For teams using continuous deployment, our wildcard certificates integrate with automation tools. Deploy a new feature branch to feature-xyz.yourdomain.com and it is immediately served over HTTPS with no certificate provisioning step needed. This eliminates SSL as a bottleneck in your deployment pipeline and keeps your team moving fast.

Managing a wildcard SSL certificate through AnubizHost is as simple as managing a single-domain certificate. Your dashboard shows the certificate status, expiration date, covered domains, and installation locations in one view. When the certificate renews, it updates everywhere simultaneously — no per-subdomain action required.

If you need to reissue your wildcard certificate due to a key compromise or server migration, the process takes minutes. Generate a new CSR, request reissuance through your dashboard, and the new certificate is available for download immediately. We also provide one-click reinstallation for all hosting accounts linked to the wildcard.

Our API supports wildcard certificate management for customers who automate infrastructure. Retrieve certificate details, trigger reissuance, download PEM files, and check expiration dates programmatically. Integrate with Ansible, Terraform, or custom scripts to keep your wildcard SSL synchronized across every server in your fleet.
