A one hundred percent availability guarantee. Nobody can give one because no data centre gives one. Whoever promises it either has not read their own hosting contract or hopes you will not check.
A promise that the site will not be hacked. Maintenance reduces the risk considerably and does not remove it. What a contract can promise is a response in an emergency and a backup the site can be restored from.
And automatic renewal for twelve months with three months notice. For a service delivered monthly that is unusually long. Our contracts run monthly and can be cancelled at the end of any month.
