I read the above with below example :
A residential building has a gate,wall and few security personnel for
safety against theft etc. In two years, there was no major theft or
issues and hence the residents decided to remove the building gate,
security personnel !  Oh yes, the security guards were black cat
commandos !

Your discussion with the security administrator was very interesting
however it would be good to know:
1) How and were are the IPSs placed in the network ?
2) What Signature profile are they using for these IPSs ? Many IPSs
comes with default settings for low detection.
3) Did they tune the IPSs as per their own requirement ?
4) How often they patched the IPSs ?
Lastly, are the IPSs purchased because they were needed *or*  the
company was fooled to buy it or had budget/ policies/ vendor
commitment to buy it   ?

It all depends what are you safe guarding !

For example: A common man's residential building will have 1 security
guard however the President's residence will have range of security
gadgets, various check points, many many security guards !!!
