Sumafu199267dWhy do you think so?
Cisco still uses IOS for their devices,
Their own OS, that they have written before the time of Linux and FreeBSD.
Its lacks many features that are a staple in modern OSes, like preemptive multithreading, virtual address spaces, namespacing,...
You know, shit that is actually relevant for performance and security.
Furthermore IOS doesn't even have a fucking posix-shell, but a hacked together mess of none sensical commands (at least if you're used to proper OSes).
Voxera704167dWell I tried to use one if their higher end firewalls for 6 months.
Anytime w tried to do anything beyond the most basic things, rules stopped working without explanation or logic pattern
And since I have experience of old windows firewall, ipchains, iptables, enternet(now clavister) and fortigate I consider my knowledge above beginner bu their java based gui (requiring an obsolete java version) was completely horrible with multi level popups and almost no overview.
unclekev16464dCisco is overpriced & insecure junk.
arcsector183563dIm late to this rant, but i really do believe this is one of the main reasons that people are going to cloud; this is all abstracted, and you don't really have to deal with this kind of hardware.
