使用siteground共享主机，是否提供安全防护？

首先看一下官方的解释：https://www.siteground.com/kb/how_does_siteground_protect_my_website/

安全措施如下：

1. We have sophisticated IDS/IPS systems which block malicious bots and attackers (Intrusion detection/prevention systems).

We are constantly monitoring for vulnerabilities in the most popular applications and modules and whenever possible we develop virtual patches in the form of WAF rules (Web application firewall).

2. 安装了ModSecurity

ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx that is developed by Trustwave’s SpiderLabs.

综上所述：SG是提供了WAF防火墙错误的。
