Cathryn Halton, who joined last week from transport operator FirstGroup, has more than 10 years marcoms experience across a range of sectors. She has also previously worked at G4S.
She said: "Working with the regional teams, my aim is to enhance the local and national profile of the brand, positioning Securitas as one of the leading security companies in the UK. Critical to this will be connecting and engaging our external and internal stakeholders with our vision and demonstrating that we have the experience and expertise to deliver on this commitment."
Brian Riis Nielsen, UK country president at Securitas, said: "Cathryn has proved herself to be a highly respected, competent and confident leader who can engage and influence people at all levels. I'm delighted to welcome her to the team and am looking forward to working with her to achieve our business priorities."
She will be based at the new Securitas Operations Centre in Milton Keynes.
