AutoSSLs: Agent-Based SSL Certificate Automation

AutoSSLs is an agent-based SSL automation system developed by SSL2BUY that runs on your server and takes over routine certificate tasks. It handles CSR generation, validation, SSL installation, and HTTPS configuration on supported servers, then replaces eligible certificates before they expire. Once configured, it reduces manual work across each certificate cycle.

AutoSSLs handles the recurring steps from certificate request to deployment. The agent generates key pairs and CSRs, submits certificate requests, completes supported validation, and retrieves issued certificates. It then installs them and updates HTTPS bindings and web server configuration where needed.

The agent checks certificates on a schedule and starts automatic replacement 21 days before expiry. It applies the new certificate and updates the server configuration, reducing the steps your team needs to repeat each cycle.

Why it matters now: Publicly trusted SSL/TLS certificates issued since March 15, 2026 have a maximum validity of 200 days. The limit drops to 100 days on March 15, 2027, and 47 days on March 15, 2029. Shorter lifetimes mean more frequent certificate replacements and more recurring work to automate. See the validity timeline.
CSR & Certificate Request

CSR & Certificate Request

The agent generates a key pair and CSR on your server, then submits the CSR to request a certificate from SSL2BUY. The private key is never sent externally.

No CSR tools or copy-pasting
Validation

Validation

The agent completes domain validation through your selected method: an HTTP file it places automatically, a supported DNS API, or Managed DNS after a one-time CNAME setup.

No validation values to place each cycle
Certificate Retrieval

Certificate Retrieval

Once issued, the agent retrieves the certificate from SSL2BUY over TLS and prepares it for installation on your server.

No downloading or moving files
SSL Installation & HTTPS Setup

SSL Installation & HTTPS Setup

The agent installs the certificate and updates HTTPS bindings or web server configuration on supported servers. It reloads the web server where needed.

Fewer manual configuration steps
Replacement Before Expiry

Replacement Before Expiry

The agent checks certificates on a schedule and starts automatic replacement 21 days before expiry. It installs the new certificate and updates HTTPS bindings.

Prevents expired-certificate errors

Validation Methods

Choose How Your Certificate Is Validated

AutoSSLs currently automates domain validation through file validation, a supported DNS API, or Managed DNS. Choose the method that fits your web server and DNS setup. Once configured, AutoSSLs handles recurring domain validation during certificate replacement.

File Validation

File Validation

The agent places the validation file on your web server automatically, removing the need to upload it manually.

Initial setup
Select File Validation on your order.
Keep in place
The validation file must be publicly accessible over HTTP when validation runs.
Suitable for
Single-domain and multi-domain certificates on public web servers.
DNS API Validation

DNS API Validation

AutoSSLs connects to your DNS provider’s API to create and verify the records needed for domain validation.

Initial setup
Select your provider, enter the required API credentials, and click Verify & Save.
Supported providers
Cloudflare · AWS Route 53
Keep in place
Maintain valid API credentials with permission to manage validation records in the domain’s DNS zone.
Suitable for
Domains using supported DNS providers, including wildcard certificates.
Managed DNS Validation

Managed DNS Validation

Add a one-time CNAME record to delegate domain validation to SSL2BUY. AutoSSLs then handles future domain validation automatically.

Initial setup
Add the CNAME record provided on your order. After DNS propagation, click Verify & Save.
Keep in place
Retain the CNAME record while automation is active. Removing or changing it can interrupt validation and certificate replacement.
Suitable for
Domains where you can add a CNAME record, including those using DNS providers without API integration.
Note: Available validation methods depend on your certificate type. Your order details page displays the applicable options.

Common Questions

AutoSSLs Frequently Asked Questions

Straight answers about eligibility, validation, replacement and access.

What is AutoSSLs?

AutoSSLs is an SSL certificate automation agent developed by SSL2BUY. It runs on supported servers and handles certificate requests, validation, retrieval, installation, HTTPS setup, and replacement before expiry for eligible certificates.

Which certificates work with AutoSSLs?

AutoSSLs currently supports eligible SSL2BUY Domain Validated (DV) certificates, including single-domain, multi-domain (SAN), and wildcard certificates. Eligible orders display an Automatic Installation option on the order details page.

Which servers does AutoSSLs support?

AutoSSLs supports IIS on Windows Server, Apache and NGINX on Linux, and Apache or LiteSpeed through cPanel + WHM. Setup requires administrator access on Windows and root access on Linux and WHM.

Which validation method should I choose?

Choose file validation for a publicly accessible web server, DNS API validation for Cloudflare or AWS Route 53, or Managed DNS if you can add a CNAME record. Your order displays the methods available for your certificate.

Does AutoSSLs renew my SSL2BUY subscription?

AutoSSLs automates certificate requests, installation, & replacement within active subscription. It doesn’t extend your subscription or process renewal payments. Renewals and billing are managed separately in your SSL2BUY account.

When does AutoSSLs replace a certificate?

AutoSSLs starts automatic replacement 21 days before expiry. The agent requests the new certificate, completes supported validation, retrieves it once issued, and installs it with the required HTTPS configuration.

Do I need to keep the Managed DNS CNAME record?

Keep the CNAME record unchanged while Managed DNS automation is active. Removing or changing it can interrupt validation and certificate replacement.

Do my private keys leave my server?

No. Private keys are generated and stored on your server and are never transmitted externally. The agent submits the CSR to request the certificate.

Is there a separate charge for AutoSSLs?

No. Right now, AutoSSLs is included at no extra cost with qualifying SSL2BUY certificate purchases. You only pay for the SSL certificate itself.

Can I switch between manual and automated installation?

You can switch between manual and automated installation from your order details page whenever you need to.

What if my server is not supported?

Choose Manual Installation on your order and install the certificate yourself. SSL2BUY Support can help you check compatibility and review alternative automation options, including ACME SSL certificates.

How do www and non-www names work on a multi-domain certificate?

The www and non-www versions of a domain count as separate names. Include both if you need coverage for both. Your order shows the number of names included with your certificate.
