Check that your installation method supports both your server and your certificate type.Use automatic renewal where supported. Check completed tasks and any issues that need your attention in the dashboard.
Renewals require a working connection, successful validation and the appropriate plan or account balance.INSTALLATION OPTIONS
Install Agent on the server that will use the certificate, or use Gateway to reach several servers remotely.
Agent runs on your Windows or Linux server. It carries out the certificate installation and renewal tasks sent from your dashboard.
Gateway runs on a Windows machine and connects to the servers you authorize. It uses WinRM HTTPS for IIS and SSH for Linux servers.
Gateway currently installs single-domain certificates only. You can purchase wildcard and multi-domain (SAN) certificates, but Gateway cannot install them.
Connect to supported cloud services, network devices and hosting control panels through their APIs. Validation and installation steps depend on the system you use.
SUPPORTED SYSTEMS
Find a supported connection for your server or service. The documentation explains the permissions and setup steps you need.
Manage HAProxy certificates through Gateway, and Tomcat or IBM HTTP Server certificates through Agent.
The steps for importing and activating a certificate depend on the service or device.
cPanel/WHM and Plesk connections are in beta. Test them in your own environment before using them in production.

Certinite lets you buy commercial SSL, install certificates on supported systems and track renewals in one dashboard. Choose brands including Sectigo and GeoTrust with different coverage options. Automation for free Let's Encrypt certificates is also available.
Agent is installed on the server that uses the certificate and runs tasks there. Gateway connects to several servers remotely from a Windows machine. It uses WinRM HTTPS for IIS and SSH for Linux. Choose based on how you want to access your servers.
Yes. You can buy wildcard, multi-domain and multi-domain wildcard certificates. However, not every installation method supports every product. Gateway, for example, currently installs single-domain certificates only.
No. Automatic renewal depends on the certificate type, validation method, system and plan. Supported DNS providers can automate validation. With manual DNS validation, you may need to add a new DNS record yourself. Connection problems or insufficient balance can also stop a renewal.
Let's Encrypt certificates are free. Certinite helps you obtain them, install them on supported systems and manage renewals from one dashboard. You can also track certificate details and task status. Management features and pricing depend on your plan.
It depends on the certificate and validation method. Current Let's Encrypt and DNS validation processes may generate the key in Certinite's central system and send it to the server in a PFX file. For commercial certificates validated over HTTP, when the CSR (certificate signing request) is created on the server, the private key is generated there too. See the setup and security documentation for details.
