Trust is the currency of whistleblowing.
An employee who witnesses fraud, harassment or a regulatory breach will only report it if they believe their concern will be taken seriously, handled confidentially and acted upon without personal consequences. Where that trust is absent, the concern goes unreported – or is taken to an external regulator, the media or a lawyer, with far greater risk to the organisation.
A growing body of research suggests that the structure of the reporting channel – specifically whether it is managed internally or by an independent external provider – has a measurable impact on whether employees trust the process enough to use it. This resource examines what the available evidence tells us about trust, channel design and reporting behaviour.
The Evidence on Internal Channel Trust
The Freshfields Whistleblowing Survey 2023, conducted across the United States, United Kingdom, France, Germany and Hong Kong, found a notable decline in the proportion of employees who would report concerns to their direct line manager: 40% in 2023, compared with 46% in 2020. At the same time, overall involvement in whistleblowing increased significantly – from 32% in 2020 to 43% in 2023, with the US seeing the sharpest rise.
This divergence is significant. People are not becoming less willing to raise concerns – they are becoming more selective about how and to whom they raise them. The decline in line manager reporting suggests that employees increasingly doubt whether internal management-led channels will handle their concern impartially, particularly when the concern involves someone in their direct reporting line or a senior figure within the organisation.
Data from Protect, the UK’s leading whistleblowing charity, reinforces this pattern. In its 2025 Impact Report, Protect handled 3,589 cases – an 8% increase on the previous year. A significant majority of callers to Protect’s advice line had already raised concerns with their employer before seeking external support, suggesting that the internal process had either failed to resolve their concern or had not given them confidence that it would be taken seriously. Protect noted as an encouraging sign that the proportion of callers whose concerns were under investigation internally had increased by around 10%, but the overall trend remains one where employees seek external validation when internal confidence is lacking.
Why External Channels Build Greater Trust
The structural advantages of an externally managed reporting channel align directly with the trust barriers that research identifies. Three factors are particularly relevant.
Independence from Internal Hierarchies
When a report is received by an external provider, the reporter does not need to worry about whether the person handling their concern has a relationship with the accused, a stake in the outcome, or a reason to minimise the issue. This structural independence removes a conflict of interest that internal channels – however well-intentioned – cannot fully eliminate. For reports involving senior management, this independence is not merely reassuring; it is essential to a credible process.
Professional Handling and Confidentiality
External providers typically employ dedicated, professionally trained staff whose sole function is to receive and process whistleblowing reports. This contrasts with internal channels where the recipient may be an HR generalist, a compliance officer with multiple responsibilities, or a line manager with no specific training in handling sensitive disclosures. The perception – and the reality – that the report will be handled by someone with relevant expertise and no competing loyalties increases the reporter’s confidence in the process.
Safecall’s own Whistleblowing Benchmark Report 2024 provides quantitative evidence for this effect. The data showed that 22.7% more reporters chose to identify themselves when speaking to a Safecall call handler than when using written reporting channels. This is a meaningful indicator of trust: a reporter who provides their name is demonstrating confidence that their identity will be protected and that the process will be handled fairly. The expertise of the call handler – in Safecall’s case, former UK police officers with over 25 years’ investigative experience each – appears to be a significant factor in generating this trust.
Consistency of Process
An external provider applies the same intake process, categorisation framework and confidentiality protocols to every report, regardless of the seniority of the accused or the sensitivity of the subject matter. Internal channels are more susceptible to inconsistency – a report about a junior employee may be handled differently from one about a board member, whether by design or through unconscious institutional bias. This consistency is not just an operational benefit; it is a trust signal that employees recognise and respond to.
What Anonymous Reporting Patterns Reveal About Trust
The relationship between anonymity and trust is more nuanced than it first appears. High rates of anonymous reporting are often interpreted as a sign of low trust – employees feel they need the protection of anonymity because they do not trust the system to protect them if identified. But the availability of anonymity itself builds a form of trust: it tells employees that the organisation prioritises hearing about wrongdoing over identifying the messenger.
The ACFE’s 2024 Report to the Nations found that organisations with anonymous reporting mechanisms experienced fraud losses that were 50% smaller than those without. This is not simply a volume effect – more reports leading to earlier detection – but an indication that anonymous channels reach reporters who would otherwise remain silent entirely. The option of anonymity is, in effect, a trust mechanism that expands the pool of people willing to engage with the programme.
Importantly, anonymity does not have to be permanent. Research consistently shows that a significant proportion of reporters who initially choose anonymity later identify themselves once they see that their concern is being taken seriously. Protect has observed this pattern, and Safecall’s data confirms it: the trust built through professional handling of the initial report creates the conditions for the reporter to engage more openly as the process progresses.
Implications for Programme Design
The research evidence supports several conclusions about the relationship between channel design and trust:
- External operation of reporting channels addresses the structural trust barriers – conflicts of interest, inconsistency, lack of professional handling – that internal systems struggle to overcome.
- The decline in line manager reporting does not reflect declining willingness to speak up; it reflects a shift in channel preference towards more independent, professional options.
- Anonymous reporting should be viewed not as a weakness but as a trust-building mechanism that expands participation and leads to earlier detection of serious misconduct.
- The quality of the person receiving the report – their training, independence and professional manner – directly influences whether reporters trust the process enough to identify themselves.
For compliance officers building or reviewing a whistleblowing programme, these findings argue strongly for a multi-channel approach anchored by an independent external provider. The technology matters, but the trust equation is ultimately determined by the structural independence, professional credibility and consistent confidentiality of the service behind it.
