Preventing Phishing Links from Free Hosting Domains in Email Attachmen

[DeepakRajAwasthi43351]

How can I prevent emails with links from free hosting websites? I've noticed that some senders are disguising image attachments as small PDF logos. These images contain hyperlinks that lead to phishing websites. Even though ESA shows the URL as reputable, we need a way to block URLs from free hosting domains as a precaution. Is there a feature that can help with this?

Are there any features to set up rules or filters to automatically flag or quarantine emails containing links from free hosting domains in cisco esa: Secure Email, Gateway C395, Version: 14.2.1-020?

So... the trick is that the ESA web filtering doesn't have a category for "Free Web Hosting". There is a "Web Hosting" category that might catch the what you want.
Create a content filter to log them or quarantine them to start and see what's getting captured...
