You can't block RF unless you buy materials that are meant to block RF.

Your question is asked often. If you are trying to block signals coming from inside your building you will have challenges.

Unless you shield the building and or windows wireless will leak into your building.

If you have a rogue on your network you can do rogue containment. There are legal ramifications if you contain wireless aps that aren't on your network.

I need blockling for security of the building the outside wireless network signals, for example a SSID,

My company has a MSE(MObility Service Engine) wIPS but I do not configure.

There is no equipment that will prevent your signal from going outside. This is how wifi works. You can always lower the power or even place AP's closer to the inside of your building but you have to also consider the signal your users will get at the edge of your building.

You can look at RF Blocking material like this, but if your in a multi tenant building, you will have bleed between floors.

Tell your manager you need to build a RF faraday cage around your building ..

You can't stop RF signal from going outside. There is no equipment that will do that.

If you want to stop wireless signals from going outside the four walls, you need to wrap your structure with a Faraday mesh. It's very, very expensive.

Otherwise, you may need to consider putting wall-mounted single-directional antennas of your four walls. This'll help but it won't eliminate some signals leaking out.
