Yes, absolutely.
There's no increased cost for SSL content. We have 4 options to support SSL.
Shared SSL Certificate: this uses a shared certificate under the domain worldssl.net. When using a shared SSL certificate, your content is accessible through a URL like yourdomain.r.worldssl.net.
LetsEncrypt SSL Certificate: using our control panel, you can automatically generate an SSL certificate from LetsEncrypt.
Custom SSL Certificate: you can bring your own SSL certificate, and upload it to CDN.net at no cost.
CDN.net Provided SSL: we can provide, and manage an SSL certificate for you. Please contact sales@cdn.net so we can find the best solution for you.
