Spirent Communications plc is a British provider of automated test and assurance solutions for networks, cybersecurity, and positioning, headquartered in Crawley, West Sussex. The company traces its corporate roots to Bowthorpe Holdings, which was incorporated in 1949 and renamed Spirent in 2000 during a strategic refocus on communications testing. In October 2025, Keysight Technologies completed its acquisition of Spirent, and Spirent’s shares were delisted from the London Stock Exchange effective October 17, 2025.[1][2]
Design and History
The Spirent identity was created by London design consultancy CGI, which had developed a new identity for Bowthorpe the previous year and then rebranded the group as Spirent following major corporate changes, including a new chief executive and revised strategy.[3] The name Spirent was chosen to reflect the spirit of “inspired innovation,” which the company said went to the heart of all its activities.[3]
The current Spirent logo mark is registered as a trademark consisting of a circle comprised of two stylized arrows.[4] In August 2018, Spirent launched a company-wide business initiative called “Promise. Assured.” supported by a new branding campaign emphasizing the company’s capabilities to bring clarity to increasing device and network complexity.[5][6] A Chinese industry publication reported that on August 2, 2018, Spirent released a new logo, new image, and new business strategy, with “Promise. Assured.” becoming part of its brand logo.[7]
Meaning and Symbolism
The Spirent name itself carries documented meaning: it derives from the phrase “inspired innovation,” as stated by the company during the 2000 rebranding.[3] [4]
Typography and Design
No official documentation has been published identifying the specific typeface used in the Spirent wordmark or the exact color specifications of the logo. The trademark registration describes the mark as consisting of a circle comprised of two stylized arrows, which is the extent of the officially documented visual description.[4]
