Not sure about whether it&#x27;s subversion or basic hacking. You should assume, though, that they might have hacks in any common product that can be used for a security bypass. Here&#x27;s why: IT markets usually become oligopolies where a few players products are all over the place. Firewalls, routers, VPN&#x27;s, OS&#x27;s on desktop, OS&#x27;s on mobile, net configuration, build systems... handfuls of implementations in each dominate in market share. So, rather than beating everything, you can focus on 0-days in a tiny few to beat almost everyone [that matters to a TLA].<p>Another side of this coin is that they&#x27;ll add to their hitlist whatever they encounter the most. They probably run into Juniper firewalls all the time. So, it&#x27;s higher priority. Using high-quality, but lower-priority-to-them, components reduces you risk of being hit by them. So, one of my recommendations is to build&#x2F;use strong systems, use diverse components of good quality, and obscure the workings of both at the interface. They&#x27;ll trip your alarms trying to figure out what you&#x27;re using before they hack you.
