I can only recommend what I know myself. I have a quite large shop and for the first time I learned about the ddos attacks when the site didn’t work for a day and I lost a large number of orders. When the situation repeated I realized that it's time to move to a hosting with protection. In the process of searching the right service I came across an unknown to me earlier StormWall, I took a chance and was pleasantly surprised! At least everything works well and for me this is the major criterion.
