Sophos Group plc is a security software and hardware company. Sophos develops products for communication endpoint, encryption, network security, email security, mobile security and unified threat management. Sophos is primarily focused on providing security software to the mid market and pragmatic enterprise from 100 to 5000 Seat organisations. Whilst not a primary focus, Sophos also protects home users, through a free anti virus software trial (Sophos Home) intended to demonstrate product functionality. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.
Sophos was founded by Jan Hruska and Peter Lammer and began producing its first antivirus and encryption products in 1985.
During the late 1980s and into the 1990s, Sophos primarily developed and sold a range of security technologies in the UK, including encryption tools available for most users (private or business).
In the late 1990s, Sophos concentrated its efforts on the development and sale of antivirus technology, and embarked on a program of international expansion. Meanwhile, Sophos opened several subsidiary operations and moved to selling exclusively with channel partners.
In the late 1990s and early 2000s, Sophos added a series of data security and protection tools and remote device administration tools to its product range.
In 2003 Sophos acquired ActiveState, a North American software company that developed anti-spam software. At that time viruses were being spread primarily through email spam and this allowed Sophos to produce a combined anti-spam and antivirus solution.
In 2006, Peter Gyenes and Steve Munford were named chairman and CEO of Sophos respectively. Jan Hruska and Peter Lammer remain as members of the board of directors.
In 2011, Utimaco Safeware AG (acquired by Sophos in 2008-9) were accused of supplying data monitoring and tracking software to partners that have sold to governments such as Syria. Sophos issued a statement of apology and confirmed that they had suspended their relationship with the partners in question and launched a thorough investigation.
In February 2014, Sophos announced that it had acquired Cyberoam Technologies, a provider of network security products. 
In June 2015, Sophos announced plans to raise $US100 million on the London Stock Exchange.
Acquisitions and partnerships
From September 2003 to February 2006, Sophos served as the parent company of ActiveState, a developer of programming tools for dynamic programming languages. In February 2006, ActiveState became an independent company when it was sold to Vancouver-based venture capitalist firm Pender Financial.
In May 2011, Sophos announced it had entered into an agreement to acquire Astaro, a privately held provider of network security solutions, headquartered in Wilmington, Massachusetts (US) and Karlsruhe, Germany.
In April 2012, Sophos acquired DIALOGS, a privately held provider of mobile management solutions, headquartered in Germany.
In October 2014, Sophos acquired Mojave Networks, a leading cloud based security startup.
November 2015, E-rong Consultants Co., Ltd (former Cyberoam Thailand Distributor was joined to be Thailand Distributor of Sophos.
