Not so long ago I have obtained ssl certificates for all of my domains, including thedatawise.com. So from now on it will be safer to browse my blog. Also whole traffic from http is redirected to https, so there is no way to use unsafe version of the website.
The certificates were issued by Let’s encrypt, and it is fairly easy to install them on webfaction.comm, which I use as a hosting service. If you have any questions regarding the procedure, or the hosting itself feel free to ask them in the comments below.
