Cybersecurity firm Siren accelerates momentum with EUR 12 million European Investment

EIB support global fight against crime

Siren, the investigative intelligence company on a mission to keep people, assets and networks safe, today announced that it had received EUR 12 million in funding from the European Investment Bank

The announcement comes off the back of a record year for Siren. The firm reported 162% revenue growth, it achieved its first patent with four additional pending, established a brand new headquarters in the Galway Innovation District and was acknowledged in the Deloitte Technology Fast 50 as one of the fastest growing companies in Ireland. 

In the same period, Siren signed several partnerships to bring a more complete suite of intelligence sources to its customers and differentiate itself in the marketplace as a single search experience across all third party data. The new data partnerships provide commercial risk intelligence, open source intelligence (OSINT), dark web intelligence and cyber threat intelligence. In addition, Siren launched Siren Consulting, a new strategic and applied projects unit of the company.

Data For Good

Siren provides an advanced intelligence platform to law enforcement agencies and organisations responsible for maintaining public safety around the world. Siren allows investigators to make complex searches, organise the results visually and create advanced reports to share findings with their teams. The platform is also used by large Corporations to protect their assets and networks against fraud and cyber threats. 

Siren has partnered with US based non-profit organisations like the Anti-Human Trafficking Intelligence Initiative (ATII) and the National Child Protection Task Force (NCPTF) who use its patented technology to solve complex intelligence problems, identify traffickers and reduce human trafficking. 

“It’s a real milestone that Siren has been endorsed by the European Investment Bank and we are very grateful. For a company at Siren’s stage of growth, access to funding of this magnitude will fuel our rapid expansion plans and allow us to provide many more organisations with access to our unique technology,” said John Randles, CEO of Siren.

“The European Investment Bank is committed to supporting cybersecurity innovation and accelerating development of cutting-edge technology to improve security of citizens around the world. The EUR 12 million backing for Siren will enhance analysis and investigation of data to combat human trafficking, strengthen law enforcement and tackle fraud.” said Kris Peeters, European Investment Bank Vice President.

This latest funding will further support the development of the Siren platform at the new global R&D centre in Galway, to increase headcount by 50% over the next two years, to elevate the Siren brand and to market Siren capabilities to a wider global audience. Crucially, it will enable Siren to provide increased value for clients specifically in cyber threat intelligence, operational monitoring, financial crime, and law enforcement and intelligence. In 2019, Siren received $10 million in Series A funding led by Atlantic Bridge.

The Demand for Investigative Intelligence

The 2022 INTERPOL Global Crime Trend Summary Report found that the five types of crime it monitors globally have either endured or escalated, notably through the global pandemic and continue to pose a serious threat to the security and well-being of public and private entities and actors, from government agencies and corporate businesses to individual citizens. According to the FBI, the number of murders rose in 2021 nearly 30% from in 2020, the largest single-year increase ever recorded in the U.S.

In addition to these violent crime trends, synthetic narcotics trafficking syndicates are continuing to expand the scale and scope of their operations. This trend is most acute in the Five Eyes nations of the United States, United Kingdom, Australia, Canada and New Zealand. Given the deliberately decompartmentalized and highly networked nature of these syndicates, Siren’s multi-domain data aggregation and network graph generation capabilities are essential for investigators.

Siren enables organisations to close cases faster by accelerating investigations with easier access to previously unconnected data. Organisations can visualise, analyse and subsequently disseminate a more precise set of data relationships at machine speed and scale.
