Stolen personal information, synthetic identities and compromised credentials can all help criminals bypass traditional fraud checks, putting regulated financial institutions and fintechs at risk.
For compliance and fraud prevention leaders, effective identity theft prevention requires more than checking whether documents look genuine. Firms need reliable digital verification, connected risk signals and ongoing monitoring to identify suspicious activity before it leads to financial loss.
Many fraud prevention processes focus on validating identity documents and matching customer information against available records. While these checks remain important, they may not establish whether the person applying is genuinely entitled to use that identity.
Fraudsters can exploit gaps between verification systems, inconsistent data and limited checks at onboarding. A document may appear legitimate, for example, while the information submitted alongside it raises concerns that are not detected by a single verification method.
This is not a theoretical gap. Our 2026 UK Compliance Reality Check, based on a survey of 1,000 senior decision-makers across UK regulated sectors, found that 54% of identity verification checks are still being conducted manually. Where identity relies on human review of documents alone, the opportunity for fraudsters to exploit inconsistencies grows significantly.
These security vulnerabilities can allow fraudulent applications to pass initial checks and create opportunities for financial crime.
Identity fraud commonly involves stolen personal information or synthetic identities created by combining genuine and fabricated details.
Stolen identities allow criminals to impersonate real individuals, while synthetic identities can be more difficult to identify because they may not correspond to one genuine person. In both cases, applications can appear credible when fraud checks rely on incomplete information or isolated signals.
Compromised login details create another risk. Even when an account was opened legitimately, criminals may later use stolen credentials to gain access, change account details or carry out unauthorised transactions.
The scale of this challenge is well understood by compliance leaders. In our 2026 research, 78% of UK regulated firms said they were confident their Enhanced Due Diligence processes would stand up to future regulatory scrutiny, but only 29% described themselves as very confident. That gap between confident and very confident is where identity fraud finds its way through.
This is where identity theft prevention must extend beyond onboarding and account creation.
A stronger approach combines multiple checks to build a more complete picture of identity and risk.
Regulated firms should consider whether their fraud prevention services can:
This matters because the controls that stop identity fraud at onboarding are not the same as the controls that catch it later. Our research found that 52% of UK regulated firms struggle to verify beneficial ownership across complex ownership structures, which is precisely the terrain synthetic identities exploit. Firms that treat identity as a one-off check rather than an ongoing one are the ones most exposed.
Combining these controls can improve fraud detection while helping firms avoid unnecessary friction for legitimate customers.
Account takeover presents a different challenge from fraudulent onboarding. Instead of creating a new account using a stolen or synthetic identity, a criminal gains control of an existing customer account.
Identity verification at onboarding alone cannot prevent every subsequent attack. Firms should consider how they identify suspicious changes in account access, customer information and behaviour, and how those signals feed into their wider risk management processes.
This is also where the manual versus automated question becomes most pressing. Only 30% of UK regulated firms currently use or plan to use AI to triage alerts on PEP and sanctions screening, meaning the remaining 70% rely on human review of every alert. For account takeover specifically, where speed of detection matters most, that gap is where real losses accumulate.
Clear escalation procedures are also essential. When checks identify potential identity fraud, teams need a consistent way to investigate concerns and determine the appropriate next steps.
SmartSearch brings identity verification, AML screening and ongoing monitoring together within a connected compliance workflow. This helps regulated firms strengthen customer due diligence and gain greater visibility across the customer lifecycle.
By reducing reliance on fragmented checks and manual processes, connected compliance technology can help teams identify potential risks more efficiently while supporting a smoother onboarding experience.
For compliance and fraud prevention leaders, the goal is to build a process that supports both effective identity theft prevention and operational efficiency.
Identity theft can evade fraud checks when firms rely on limited verification signals, disconnected systems or one-time onboarding controls. Stolen identities, synthetic identities and compromised credentials each expose different weaknesses.
A layered approach combining reliable digital identity checks, stronger fraud detection, AML screening and ongoing monitoring can help regulated firms reduce security vulnerabilities and account takeover risk.
For financial institutions and fintechs, effective identity theft prevention means looking beyond whether an identity appears genuine and assessing risk throughout the customer relationship.
