URL filtering with regex

[newton.travis]

Hello,

In an ongoing cat and mouse game, we're trying to filter out using proxies and sites that bypass web filtering. Since it's impossible to block everything, I'd like to do some regex filtering to look for keywords like "bypass", "proxy", "youtube", etc.

Does Firepower have the ability to do regex on policies?

Thanks!

Manual URL Filtering

• You can override URL Categories and Groups by configurating manual URLs

• Wildcard isn't support

• For example, if you block a URL category which contains a single URL to be whitelisted, you can configure a rule with the whitelisted URL added manually before the blocking rule
• When configuring Manual URLs, any match of the URL string will trigger action.
