Answer:
Both insurance and surety provide protection against financial loss. Insurance anticipates losses and charges a premium with that in mind where surety companies expect no loss and the premium charged is a 'service fee'. Surety bonds involve three-parties the surety company, principal and obligee. Insurance involves two-parties the insurance company and the insured. With insurance the risk is transferred to the insurance company where as with surety the risk remains with the principal. The surety is providing a guarantee against loss by agreeing to be responsible for the obligation of the principal.
