You can install SEP with IPS to block some attacks, but SEP does not provide full protection against web attacks.
To protect web sites you should look into a Web applicaton firewall (WAF). A WAF will protect your web server against hacking attempts. See: https://www.symantec.com/products/web-application-firewall-reverse-proxy
