This updating summary prospectus provides updated information about Opportunity+ Variable Annuity (the "contract"), an individual deferred flexible premium variable annuity contract. The contract is issued by us, Union Security Insurance Company ("Union Security," "we," "us," and "our") and administered by Talcott Resolution Life and Annuity Insurance Company ("Talcott Resolution," "we, "us," "our")
