Performance, et al.
In terms of performance, I think it's also important to look at how NGFWs perform in "regular" tests and how they perform in real-world or simulated real-world environments for the purposes for which they'll be used.  Testing by companies such as NSS Labs has shown substantial differences here.

And, of course, don't forget total cost of ownership!  ;)

gotta love stateful walls.
i love my big ngfw's...have did all the training on dell and fortinet and cisco with the certs and cant move on without becoming a "partner" of dell or pay sans crazy $ to proceed :(

sonicwalls integration with rsyslogs and some of the new logging and analytics (splunk) and machine data aggregation is cool too.  What worries me is the fact that you are in essence sending your most crucial logs and means of tracking down an attacker to another network (cloud) and having faith that the data wont be mined and activities tracked by a 3rd party.

It seems as if this would be a prime target with a large attack surface for a big brother type to harvest and there are a lot poping up nowadays.

Or perhaps all you can do is have your logs done in house or at best smtp smnp or ftps behind said firewall and block all the ports and protocols that you can and auth as much as u can ;) 

the ssl/tls dpi, vpn, ids, ips, application filtering, l2 bridging are bonus's imho

#EDIT  the log system i was thinking of was "smnp (v3)", "not as earlier smtp"

Reply to Joe...

The throroughput on some of these puts you off when u first realize it.


Every ips, ids, deep packet inspection feature costs you crazy thoroughput/

On a 350mb/s connection i only get 175mb/s

"... Every ips, ids, deep packet inspection feature costs you crazy throughput"

Not only that but also the false positives of IPS. Ceratin packets would be dropped and that would increase traffic in the network so waste of effort.

Good point. If this is your perimeter firewall everything coming to your network in passing over it so it has real sensitive information where your log is actually your data. I could not give it to a third party.

Re: gotta love stateful walls.
@hewent: You're not the only one with such concerns.  Indeed, the US cloud industry has lost dozens of billions of dollars since the Snowden revelations because of people being concerned about federal spooks spying on their cloud-stored data (or, for that matter, hackers using the same backdoors the feds were).

I agree. The performance of doing its job with a high speed so it is not a bottleneck in the network but also with a high quality so it does not make false positive decisions.

Firewall vs. Security
I enjoyed reading the article. Firewall and security are not the same think anymore. It is good that IPS is part of modern firewalls but  that is not what is helping in reality today. There is no intrusion but there is an attack.  We just heard a ransomware  attack today where they had bot IDS and IPS enabled in their network.

Firewalls and cost
 

Another point I would like to make is that the more complex the firewalls get the more expensive they will be for sure.  The problem is that does not solve our security issues, we need a layered approach when it comes to implementing security measures in our infrastructures to avoid vulnerabilities being exploited.

Re: Firewalls and cost
@Dr.T: It's worth pointing out that if you consider total cost of ownership (TCO) as opposed to initial purchase price, the most secure or most cost-effective NGFW is not necessarily going to be the most expensive.

NSS Labs just did an interesting study on this; I reported about it for Dark Reading's sister site, Network Computing, here: networkcomputing.com/network-security/next-generation-firewalls-put-test/379303122

(That said, however, the Palo Alto NGFW tested in this reportedly has a huge initial purchase price and TCO, but performed extremely well in almost all security and performance tests.  It didn't make the "Recommended" cut for NSS Labs strictly because of cost issues.)

How Machine Learning, AI & Deep Learning Improve Cybersecurity
Machine intelligence is influencing all aspects of cybersecurity. Organizations are implementing AI-based security to analyze event data using ML models that identify attack patterns and increase automation. Before security teams can take advantage of AI and ML tools, they need to know what is possible.
