One of my many roles as a founder and CTO is to meet with customers and talk about their network security issues. These visits are not only informative, they can be humorous as well. For example, a recent visit to a large, fortune 500 company, they told me that one of our firewall competitors explained [...]
There’s a great article on SearchEnterpriseWAN about a Palo Alto Networks customer. IDT spoke to SearchEnterpriseWAN about its experiences using next-generation firewalls from Palo Alto Networks, and discussed some of the benefits and changes their team recognized in managing security across their enterprise. IDT describes many of the usual benefits around application visibility and control [...]
There is a somewhat erroneous assumption that the web provides anonymity – in particular when someone is posting a comment on an article. And then there is the old saying that knowledge is power. The challenge some people face is what to do with it.

In reality, [...]
This Mashable news article talks about how companies are blocking social networking sites. I would call this an exercise in futility. I say this because users will find a way. Social networking, along with IM, Twitter and streaming music have become part of many employees’ daily fabric. When companies try to block these applications, several [...]
As some of you may have heard, Palo Alto Networks dropped an iPhone app late last week. We built it primarily so that our customers and partners could have an in-pocket version of our Applipedia, but there are a couple fun features in there too (e.g., access to this blog, Palo Alto Networks videos).
The most recent discovery of the first lady’s safe house (Laura Bush) and a detailed list of the civilian nuclear complex, including precise locations of weapons grade nuclear fuel follows closely on the heals of previous P2P discoveries of Marine One blueprints and healthcare records.

This Network World article talks about the hidden threat posed by rogue IPv6 usage. To a certain extent, this is a bit of a red herring and here’s why.
