Kapersky Lab is set to open a London office to serve as its base for European operations.
The endpoint security firm will be able to house more than 100 employees in the building near Paddington Station come October as it seeks to bolster its trade in Europe.
Its UK MD, Malcolm Tuck, will become the company's European director of strategic alliances, and will report to Europe MD Alexander Moiseev.
Kirill Slavin will become UK MD this month after tenures at Pepsi, Deloitte & Touche and Rinaco Plus.
Moiseev said: "The move to make the UK operation more prominent is testament to the importance the company places on the UK and European markets.
"A flagship office in the thick of the business centre of London, together with these new appointments, will bring us closer to our customers, and our goals."
The relocation from Kapersky's Abingdon offices will be rolled out over two years, with sales and marketing teams the first due tomove in in mid-October.
Moiseev said: "We are confident that having UK, European and global functions in one dynamic new office will aid synergy and integration across the business, resulting in an all-round better customer experience."
