Help me with this work, please

Suppose you are a field manager in the operations and security management department at Meta. Following the events mentioned in this article, you announce to the Management Team that you have found an insurer who agrees to protect Meta against these new attacks which would cost it less than the one Meta is currently doing business with, while offering additional or even improved protection. Despite the appearance of obvious optimization of security and protection of customer data, the management team refuses to change insurers. It is claimed that Meta has done business with this insurer since the beginnings of Facebook and that we do not want to change this business relationship. What cognitive bias influences the decision of the Management Team? (2 points) Briefly explain or justify your answer.
