Thom Langford
Global Security Advocate, SentinelOne

Thom Langford

In December 2020 Thom joined SentinelOne as a global Security Advocate. Thom established himself as CISO at large global organisations, having founded their security teams and services from the ground up. He also founded (TL)2 Security, an international strategic information security consultancy. He is an information security professional, award winning blogger, industry commentator and international speaker appearing regularly as a speaking head and presenter on topics relating to information security, risk management and compliance. Thom lives in the beautiful countryside of Chippenham in Wiltshire (UK).

As Chief Information Security Officer of Publicis Groupe, Thom was responsible for all aspects of information security risk and compliance as well as managing the Groupe Information Security Programme. Additionally the role was responsible for business continuity capabilities across the Groupe’s global operations.

Having successfully built security and IT programmes from the ground up Thom brings an often opinionated and forward thinking view of security risk, both in assessments and management, but is somehow able to do so with humour and pragmatism (mostly).

Thom contributes to a number of industry blogs and publications, including his own award-winning blog. Thom is also the sole founder of Host Unknown, a loose collective of three infosec luminaries combined to make security education and infotainment films, podcasts and other media.
