@jaredbusch Right but my question was related to ACLs, not IDS/IPS.
Did they have compliance requirements that would drive IDS/IPS? Honestly, I wouldn't deploy an office network without some sort of layer 7 edge inspection. Users are just too dumb...
No compliance related things, yet at least.

@scottalanmiller Right, but now almost everything is HTTPS.
Oh, I see what you mean.

@jaredbusch I know firewalls use rules. In Sophos and Sonicwall and others, I'm sure, you can define a host, network and service and call it something like ServerA and drag and drop the hosts/ip address, services and networks to create the rules.
An ACL provides rules applied to IP address and ports.
What you are describing is not an ACL. It is a group or list of information applied to an ACL.
In the VyOS/EdgeMax world, you can see an example in my router snippet above. I have a firewall group named Strongarm.io that is an address group of two addresses.
That group is applied to rule 1 of ACL named WAN_OUT

An object based rule engine. This is what most modern firewalls have moved to.

@wrx7m Inbound attacks on systems you are hosting it's still an issue (and yes, your IDS/F5/LB's need to terminate SSL for this to work). On the outbound traffic, there's a lot that can be inferred from what/where you are talking to. If someone is phoning home to a known bot C&C system then you likely want to know that...

A lot of malware such as ransomware is delivered from legitimate SSL sites that have been hacked.
So if you don't have some kind of SSL Inspection (like SonicWALL's SSL-DPI), then you are solely relying on your users' AV and ability to spot fake "java update" ads for example.

You are relying on the same thing in both cases, just one runs no a central processor and one runs closer to the end user. Same scanning functionality, though.

No, that's not how that works. Anything that runs on the router can be run on the client machine. The idea that UTM can do something that traditional AV cannot is incorrect. It's the same thing, just one runs on a low powered shared machine and one runs on the high powered desktop.

Security in layers... why not one at the gateway?

It works because one protects against stuff that bypasses the firewall... like if you plug in an infected USB stick, or some other means of bypassing the firewall.
And the other helps against things that pass do through the firewall (like a pc connecting to the internet). Both together are better.
The SonicWALL may catch something the other does not.
The SonicWALL may deny something that an unprotected device can't see... like an iPAD with no antivirus or a cell phone on the wireless network.

Why do you need to pay so much money when you can get the same functionality free? That's my beef, not that security in-depth isn't a good thing.

Where do you get good SSL-DPI for free, with reliable gateway AV?

I meant the user spot fake ads there.

What makes you think your favored solution isn't using ClamAV and Snort under the hood?

My favored solution is local A/V on every device, such as ESET, plus at the network gateway / firewall (and using SSL inspection when possible), local firewall enabled on all network clients, etc etc.
What are you using? or are you just relying on a single layer? Can you guarantee A/V is running and up to date on every device on your wired and wireless network at all times?

I don't know what size your company is, but when you have thousands of devices and hundreds of users... you need layers. You need layers no matter what actually.

It doesn't matter what "size" the organization is, you need layered security everywhere, period.

Right now, Sophos. Soon to be Wazah and snort/clamav instead.
or are you just relying on a single layer?
No, and nobody should.

Part of the job is dealing with the public, so no. I guarantee the guest network is littered with junk.
The secured network tho, yes.
