Corporate Investigations & Covert Surveillance Services
Independent Investigative Support for Businesses and Organisations
Businesses sometimes encounter situations where conventional management procedures, internal enquiries or existing security arrangements are insufficient to establish the facts.
Suspected employee misconduct, workplace theft, fraud, misuse of company resources, breaches of contractual obligations and other forms of commercial wrongdoing can create significant financial, operational and reputational risks.
SIASS provides specialist corporate investigation services and covert surveillance support to businesses and organisations throughout the UK.
We help clients establish relevant facts, gather independent information and obtain evidence that can support informed management decisions and appropriate further action.

Covert Surveillance for Corporate Investigations
Where necessary, lawful and proportionate, covert surveillance may form part of a wider corporate investigation.
SIASS can provide specialist surveillance support to help organisations establish relevant facts where conventional investigative methods have proved insufficient.
All proposed activity is considered in the context of applicable privacy, employment and data protection requirements.
Independent Evidence Gathering
Effective corporate investigations depend upon obtaining reliable information and maintaining appropriate evidential records.
SIASS places considerable emphasis on accurate reporting, evidential continuity, professional documentation and appropriate handling of investigative material.
Our objective is to provide clients with information that supports informed decisions, internal disciplinary processes or further legal consideration where appropriate.
Confidential Corporate Investigation Enquiries
We understand that corporate investigations can involve sensitive personnel matters, commercially confidential information and significant organisational risks.
SIASS provides a confidential initial discussion to understand the circumstances, identify the investigative objectives and consider whether our specialist services may be appropriate.
