What would be the best SSL CERTIFICATE to purchase for FMS 14

[Will Xu]

I work at a school and they access the school information system throughout the campus using WiFi.  Ever since starting there a few months ago the fact that the data in transit is not secure has been erking (if such a word exists) at me.  They are using fms 14.  I finally got the IT guys on board to install an SSL certificate on the server.  They have asked  who we should buy the cert from and what cert I recommend.  I am no security expert and now reaching out to those who are for advice.  Thank you

You could use a Lets Encrypt certs (though they're not officially supported) with FM. Free.
