How's this played by you experienced GM's? This does seem to obsolete ceramic/plasteel components almost completely.
Honestly, I rarely roll for security systems anymore and treat it more like an extended perception test for scanners to detect illegal items. Unless specific security is an important part of the run that's been prepared in advance, or they're taking weapons into public buildings, I allow the PC's a lot of lee-way for if and when security comes a calling.
Also, my group is particularly paranoid about that stuff. One even gets hermetically-sealed caseless ammo for his custom ceramic Heavy Pistol. Heinously expensive, but lets him feel a bit more secure when the other runners have decided to ditch the weapons....
Also, none of them have cyber-weaponry (no embedded shotguns or spurs) so even if Cyber is detected, most of it is legal anyway,
In public places, very few queries are raised if an R4 sin with a permit for their heavy Pistol shows up in the scanner with Smartlink-ware. The world is a much more armed and armoured place in the Shadowrun universe
As for on runs, the rigger/hacker normally own components of the security system before the sammies set foot inside, so who cares if the chem-sniffer smells C3, when the Hacker is the only one watching the alarm?
