In 1934, Erik Philip-Sörensen founded Hälsingborgs Nattvakt in Helsingborg, Sweden and after several acquisitions, the company became Förenade Svenska Vakt AB. In 1972, all security companies owned by Philip-Sörensen were gathered under the collective name Securitas. The logotype of three red dots – for Integrity, Vigilance and Helpfulness – quickly became a well-known symbol, first in Sweden, then internationally.
In 1989, Securitas began expanding internationally when it acquired security companies in Norway, Denmark and Portugal and then established an operation in Hungary. The company went public in 1991 and by January 1992, it had acquired two of Europe's leading security companies: Esabe in Spain, and Protectas in France, Germany, Austria and Switzerland. Between 1992 and 1998, Securitas made more acquisitions in Austria, Estonia, Finland, France, Germany, Great Britain, Switzerland, Spain, Sweden, Poland and Portugal. In 1999, Securitas developed a platform in North America with Pinkerton’s, Inc., the company’s largest acquisition to date. During the next year, Securitas purchased several more U.S. security companies, and acquired Burns International in August 2000. In July 2003, the combined American acquisitions became Securitas Security Services USA, Inc., a leading security company that works with more than 80 percent of the Fortune 1000 companies and has annual revenues in excess of $2.5 billion. Today, Securitas has operations in over 30 countries worldwide.
They bought Pinkerton in '99.
