i'm licensed by the state of Texas to provide a full blown crime prevention inspection, and trained in crime prevention through environmental design. i can get people up to a 15% discount on their homeowner's insurance.

i have tons of hard copy material on the topic.
i've done security surveys for huge construction companies and projects, residences, and all kinds of other commercial establishments. the worst one i did was a chemical company. the terrorist thing all of the sudden got them concerned about security. they had the worst security of any place, and they absolutely did not want to spend a penny on it (i don't know why they even called me). and to think this place was right next to a major highway, in the middle of DFW, and an explosion there would have leveled the radius of a half mile to a mile, and resulted in evacuation of half the metroplex. some people just don't have a clue. luckily they moved a little while after that.
a lot of places don't realize it, but when a security survey is done, it is basically written notification from a subject matter expert that there are known security concerns to the company. i usually have to explain this part in depth before doing the survey, and a handful have declined to continue. part of getting a lawsuit filed against a company for negligence requires foreseeability. in other words, the owner, or person in charge now knows there is a problem, and if they don't take steps to remedy it, they can be held liable, should something happen as a result of them not fixing the issue. in the survey, i might address things they would have not known about otherwise, and could use that as a defense later. when i do a survey, i usually provide the best and most optimal solution, then the most economically feasible option that still addresses the concern. no one should skimp on security, but it's the one thing you won't see any results from. if you beef up security, you might not ever know if it prevented anything. it's hard for managers to justify expenses on stuff that might never happen.
depending on the establishment, and what they're looking to address, these security reports can get pretty involved. the smallest one i ever did for a commercial place was 18 pages. the biggest looked like a novel.
i could go on and on about security issues. a lot of things are pretty simple concepts, and can easily be taught to employees. there are things employers can do to make security a mindset in employees too. if you are serious about it, i can give you my phone number and we can discuss it. like i said, it's a pretty in depth topic.
