Reducing risk in Asset Digitisation

Choosing to embrace asset digitisation carries significant financial and reputational risk. In the UK alone, the number of high value cyber-attacks have doubled in the past five years. The costs are enormous, in terms of lost assets, lost productivity, financial penalties and accumulated costs and reputational risk

Cybersecurity problems have multiplied with the rapid development of digital technology in wealth management and have dramatically increased corporate exposure to cyber-crime.
