Adding too many blocklist URLs in Content Filtering

Hello, 

I have thousands of URLs that I need to block in content filtering (around 20,000) will this put the SD WAN under too much load in anyway and affect performance?

@TLO3346 : there is no such limit define of the number of the URLs to be blocked as per my knowledge. I would say you try it and check experience !

This one's a popular internal question with newer people on our support team, so just for some additional context here: the pre-loaded categories contain hundreds of thousands, up to millions of URLs. Unless you're really determined, you're not likely to ever be able to outpace any of those 🙂

@AlexP : Yeah correct, Hope @TLO3346 checked on pre-loaded URLs as well.

This seems like an old school way of doing things.  Any reason why you can't use the built-in content filtering and threat protection system which dynamically updates without you having to do anything?

 

It's probably doing something similar, but better.

Built in? Do you mean the category filtering?

Was told by company to do it.
