From ifconfig(8). Please read both paragraphs.
Code:
     nwflag flag
             Set specified flag.  The flag name can be either `hidenwid' or
             `nobridge'.  The `hidenwid' flag will hide the network ID (ESSID)
             in beacon frames when operating in Host AP mode.  It will also
             prevent responses to probe requests with an unspecified network
             ID.  The `nobridge' flag will disable the direct bridging of
             frames between associated nodes when operating in Host AP mode.
             Setting this flag will block and filter direct inter-station
             communications.

             Note that the `hidenwid' and `nobridge' options do not provide
             any security.  The hidden network ID will be sent in clear text
             by associating stations and can be easily discovered with tools
             like tcpdump(8) and hostapd(8).
