Does Firepower eat too much bandwidth?

[srussel01]

I was talking to my reseller about buying a Firepower Module for my ASA 5516-X.

Her expert told me not to do it because it will eat too much Internet bandwidth up. (500 Mbps - 700 Mbps!!)

So I went to look online and only found one thread about this.

I have 1 GB Internet and 1GB LAN.

Does anyone have experience with this problem?

I would challenge your reseller's assertion. 500 Mbps or more is absurd. I have customers running it (Firepower Threat Defense device as Internet edge plus an FMC) on a site with a 50 Mbps circuit just fine.

The security intelligence updates will use some bandwidth but they are periodic - 2 hours by default and can be tuned to lower frequency if desired.

Thanks so much.

I appreciate your expertise on the matter.

It did not seem right to me either.
