Greyhawk provides a rapid response to whistle-blower allegations and suspicions of corporate wrongdoing.


We have supported investigations in 74 countries.

We gather facts about people and companies to enable clients to assess allegations of corruption, conflicts of interest, fraud and other serious misconduct. We can work alone or in support of internal audit teams, counsel or forensic investigators, particularly in unfamiliar and opaque jurisdictions where reliable information is elusive.

Our discreet and independent approach allows the rapid triage of whistleblower claims.

We adapt our approach to match each challenge. We combine different investigative approaches as required and in close consultation with clients. These include intelligence gathering from our human source network, covert surveillance, the analysis of public information sources across multiple jurisdictions, and specialist analysis of social media.
