Business continuity is the continuation of business operations in the event of an interruption to the “normal” means of conducting business. The interruption could be the loss of computer systems due to natural disaster or cyber attack, loss of a facility due to fire or natural disaster, or even the ability to gather everyone in the same location due to a pandemic.
A business continuity plan (BCP) lays out how to continue to conduct business in the event of such an interruption.
They want to be sure that if there is an interruption to your business that you can recover and continue to offer service to them as their business processes will be relying on the use of your service.
They may ask for a copy of the Business Continuity Plan. Additionally, they may request to see the results or report from business continuity exercises whether they be full exercises or tabletop exercises. These reports will give an indication of the ability to recover in the event of an interruption to your business.
