About us

Security teams around the world have a job to do: Safeguard their organisation’s assets, people and visitors. Therefore, they need:

  • Assurance their security measures are operational
  • Information about threats to their organisation

SIRV’s threat, incident and event reports satisfy these needs.  

Founded in 2012, SIRV is a specialist team working out of London, Melbourne, Johannesburg and, Vancouver. Our backgrounds are computer, political and data science with a focus on research.

SIRV stands for Systematic Intelligent Risk Valuation. Thank heavens for acronyms!


In 2012 brothers Phil and Andy began building SIRV.

Andy was the design champion whereas, Phil only cared for function. Andy would claim he and Phil were like two members of a rock band. They would fight for days but eventually make great music (software). In contrast, Phil thought Andy plain wrong.

By 2015 they finished arguing and SIRV was born. Since 2016 SIRV has either won or been shortlisted for innovation awards.

About us founders
