Fidelity Guarantee comes most of the time as a complement of your Property All Risks policy.
If with your Property All Risks insurance, you are covered from burglar or theft from thirds party. This policy does not cover such acts when they come from one of your employees.
Therefore, Fidelity Guarantee Insurance protects your business against the loss of money or any of the company assets result from fraud or dishonesty by one of your staff or a group of employees.
Also, this line of insurance is known as Employee Dishonesty cover or referred to as a fidelity bond, crime coverage, and crime fidelity insurance.
