Our web site before was not completely secured, and we used self-signing certificates as an interim measure to ensure that the site was secure.
Since we are not conducting e-commerce of any kind, the need for über super-secret security wasn’t necessary. Our choice was to use a more cost-effective CA provider called ‘Comodo’. Widely used and recommended for general use, Comodo services hundreds of thousands of web sites worldwide.
Thus, this web site is now secure.
