Yes, we have a network level firewall which blocks all but required traffic (HTTP/HTTPS and SSH) in addition to our in-house web application firewall (WAF) that blocks malicious attacks targeting your WordPress site.
Our WAF benefits from the collective intelligence of having had hundreds of rules baked into it from the cumulative exposure of securing all our clients over our 10+ years of hosting WordPress in this space. Pagely customers profit from the security hardening of our WAF over time as we continue to maintain and apply a strategic ruleset to prevent future attacks and protect you against new threats.
