  • Larger Font Styles

    Just a quick heads-up that I've implemented larger font variants of our forum's light and dark page styles. You can select the style of your choice by scrolling to the footer of any page here. This might be more comfortable (it is for me) for those with high-resolution displays where the standard fonts, while permitting a lot of text to fit on the screen, might be uncomfortably small.

Steve, I manage a few Sonicwalls (I prefer pfSense, but some clients prefer Sonicwall). They are all in the TZ series so not the NSA series you mentioned in the episode. The NSA series are pretty expensive and high end. I can't imagine any of them are installed anywhere there is not an IT staff, but there are probably some at the homes of some IT gurus and such. That being said, if you don't pay for support on the NSA, you cannot do this update. I suspect most of the devices of that size are under support, but just for fun, here are some prices for the device and the yearly maintenance (required if you want patches).

The entry level NSA 2650 is about $1900 for just the hardware. Support is $525/year (24x7) not including any of the subscriptions like antivirus, content filtering, etc.
The top of the line NSA 9650 is $47,000 for just the hardware. Support is $11,000/year (24x7) not including any of the subscriptions like antivirus, content filtering, etc.

So, I can't imagine anyone running one of these in a corporation without maintenance, but can certainly see old units that were replaced going home with a network guy and not having maintenance, but not the 800,000 devices you mentioned.

In the end, I don't think these devices are forgotten, at least not by the asset managers.

Great insight and numbers. Thanks! It'll be very interesting to see how this unfolds, whether the flaw can be weaponized to provide remote code execution, and also how the scan of vulnerable devices evolves over time. (y)

Just listened to your Ryuk Attack. Ugh, scary. Did you know that is an Amazon Technologies IP?
