Having an SSL certificate is a must these days. A lot of hosting providers offer free ssl integrated with their cpanel. If your hosting provider doesn’t or you just need an ssl certificate, say for a server; then SSLs.com is the cheapest place i have found.
This Basic (Positive SSL) SSL is just $3.77 USD Per Year. With other companies charging upwards of $100 for an SSL, you wont beat their prices. If you need an SSL definitely check them out.
P.S not sponsored, I really do just use them all the time
