The long-term deal will see G4S Events supply specialist response teams, hospitality and stadium safety stewards, crowd and turnstile management and car parking for the stadium's international rugby fixtures and high-profile concerts.
It will also include the provision of services to Edinburgh and Glasgow rugby fixtures.
"We have worked with the management team at G4S Events for more than ten years, and felt that introducing a long-term contract would enable both parties to further invest in the development and training of the security and stewarding staff working for us at the ground," said Murrayfield stadium manager Mark Laidlaw.
G4S Events managing director Mark Hamilton added: "Scottish rugby's long-term commitment to our services enables us to offer a bespoke stewarding and security programme to the organisation. We can recruit staff with confidence from the local area, in the knowledge that we can offer them long-term job prospects and development opportunities."
