In an era where financial fraud in the UK has ascended to unprecedented levels, with losses reaching £580 million in just the first half of 2023, the need for innovative and proactive fraud prevention strategies has never been more critical. bigspark stands at the forefront of this transformation, championing a shift from mere detection to comprehensive fraud prevention. The introduction of the contingent reimbursement model by the Payment Systems Regulator also highlights the urgency for the industry to strengthen their fraud prevention as their exposure to Authorised Push Payments Fraud has now increased.

Why Prevention Over Detection?

The landscape of financial crime is evolving rapidly, propelled by advancements in technology and the adoption of faster payment methods. This evolution has rendered traditional fraud detection systems inadequate, unable to keep pace with sophisticated fraud techniques. bigspark addresses this gap by advocating for a proactive approach that not only detects but prevents fraud before it occurs, safeguarding customers and ensuring the integrity of the financial system.

Our Approach: Data-Driven, Customer-Centric

bigspark leverages its deep expertise in data analytics, engineering, and financial crime prevention to offer bespoke solutions tailored to the unique challenges of UK banks. Our approach is holistic, focusing on continuous improvement, ongoing monitoring, and the integration of advanced analytics and machine learning models. This ensures not only the immediate resolution of fraud challenges but also the establishment of a resilient, long-term system capable of adapting to emerging threats.

Building In-House Fraud Prevention Capabilities

Our consultancy empowers financial institutions to build and enhance their in-house fraud prevention capabilities. Through a comprehensive suite of services, including data and analytics assessment, fraud data engineering, custom model development, and fraud operations optimisation, we enable banks to harness the power of their data, improve operational efficiencies, and significantly reduce their exposure to fraud.

Why UK Financial Services Must Act Now

The cost of compliance operations for UK banks has skyrocketed to £1 billion, highlighting the economic impact of financial fraud beyond the immediate financial losses. By adopting a prevention-first strategy, banks can not only mitigate these costs but also enhance customer trust and loyalty, crucial assets in today’s competitive financial landscape.
