If you're in contract security, you must understand that clients come in various shapes, sizes, professional backgrounds, and varying degrees of knowledge about security. clients who come from sales backgrounds typically have much different expectations from your program and your staff than those who come from law enforcement or military backgrounds. Their position in the company and the nature of the business itself will also dictate their view of the program and guide their expectations. To that end, try to tailor your services as a manager of a program to their needs and expectations. Try to be as objective as possible. And keep in mind that although their views and security are different from yours, had you been in their position, your views may have been similar to theirs.
Try to educate your clients as much as possible about security not only your program, many clients tend to agree with their vendors recommendation to implement a product or a service. If the vendor demonstrated this product or service or even a small practice are common and excessive. There's a standard in the industry. Take the example of people who get access cards coming into work, who should escort them to the security office for Asians of temporary cards. If the client thinks it should be a security officer, you may want to have a conversation with the client that it should be a member of the staff members team instead, due to the lack of security staff available, the inability of security to verify that the person was or was not terminated the previous day, and other considerations and this is a good example of a practice that can be implemented if you as subject matter, expert and security can take some time to educate your client about security.
The respect and trust you can gain from assuming the role of a trusted advisor go very far.
