I like that it is easy to use as well as reliable in terms of protecting my site from attacks such as DDOS's or other malicious activity online.
It has helped me protect against many different types of threats which have been very effective at keeping our website safe for visitors! There are no downsides with this service but if you're looking into using one then make sure its right fit your needs otherwise there will be issues later down the line when things do go wrong (which they sometimes can). We've had some problems over time where we were not able to access certain pages due to being under attack by hackers who used bots etc., however cloud flare was always quick enough to respond & fix any problem within minutes so all good again :).
