Not many hosters provide protection against DDoS attacks. This service will be especially relevant for loaded and popular projects and sites in very competitive commercial niches. That is, where there is a high risk of unfair competition or attracting the attention of various hackers and other "pests".I would advise you to use a hosting service that already provides protection for example https://host.discount .I have been using it for a very long time and my online store has not once been subjected to such an attack and has been working steadily for 3 years.
