Surge Protector question

I have Fios with the ONT/modem in the garage, which is plugged into power by a grounded outlet. I have a CAT6 ethernet cable that routes the internet into the house from there. Would it be valuable to add a surge protector to the FIOS ONT/modem in order to protect the equipment and, most importantly, the CAT6 ethernet cable run? If a surge protector is recommended, is there a good one that is recommended that can operate in a garage?
