Four Decades of Trusted

SIP International has earned the trust of lawyers and professionals since its founding in 1983 and is now recognised as a leading global provider of comprehensive factual intelligence to support sound decision-making in risk assessments and other areas. Our investigators have extensive experience gathering evidence in complex cross-jurisdictional fraud cases, white-collar crime, cybercrime, extortion, counterfeit product manufacturing, intellectual property infringement, murder, and more. They also excel at locating assets within offshore structures, trusts, and cryptocurrencies by analysing the techniques and mechanisms used to hide beneficial ownership. Other services include conducting physical surveillance of individuals for real-time intelligence, 24/7 online monitoring of social media posts and blogs, geofencing to capture all posts within a radius, technical surveillance countermeasures (TSCM), and various security support services.

Professional intelligence and investigation services delivered with discretion, accuracy, and legal compliance.

Corporate Investigations & Brand Protection

At SIP, we possess extensive experience in handling highly sensitive cases across the corporate and financial sectors, including fraud and other white-collar crime investigations, ransom demands, pre M&A intelligence, counterfeit products, brand and IP infringement, TSCM, 24/7 online monitoring, and more.

Fraud & Complex Global Investigations

Whether it's a fraud or any other complex investigation, at SIP, we have a team of intelligence and investigation specialists and the resources to access and extract data from the surface, deep, and dark web, as well as hundreds of public and subscriber databases worldwide. This ensures that no avenue of inquiry is left unexplored and that you receive a comprehensive, compliant, and factual report you can rely on.

Due-Diligence & Background Checks

In this era, standard KYC flag searches or general research on an individual or entity before a partnership, investment, or other purposes can be insufficient, exposing you to financial losses or fines. Not only do we possess the expertise and global resources to secure the data, but we also have human analysts who verify the facts, ensuring you receive a comprehensive report you can rely on to make informed risk assessment decisions.

Civil – Domestic - Criminal Defence – Asset Trace

For decades, SIP has provided support services to lawyers and professionals by collecting evidence for a wide range of litigation cases, including global asset tracing for financial settlements, identifying individuals involved in extortion or other crimes, tracking and recovering children following kidnapping by a parent, as well as gathering evidence for criminal defence by disproving the prosecution's case, which has often led to a not guilty verdict.

Physical Surveillance & 24/7 Online Monitoring

Surveillance is a specialised skill, and our experienced teams work seamlessly together to achieve optimal results. Whether the case involves an employee selling trade secrets, a fraudulent insurance claim, political demonstrators, the sale of counterfeit goods, or infidelity, at SIP, we gather evidence as it occurs. Our online monitoring service operates 24/7 to detect posts on social media or blogging sites for reputation management and online crime investigation. Additionally, we provide geo-fencing for VIP protection, event and venue security, crisis management, and legal research.

Technical Surveillance Countermeasures (TSCM)

Since 1983, we at SIP have specialised in Technical Surveillance Countermeasures (TSCM) for a diverse range of global clients, including financial institutions, corporations, celebrities, high-net-worth individuals, government departments, and embassies. Our head of the TSCM Department is renowned for training government agencies in TSCM and is one of a select few worldwide authorised to perform TSCM on commercial aircraft. With SIP, you can trust our expertise, professionalism, and unwavering commitment to your safety to deliver effective TSCM solutions that offer peace of mind to our clients.

SIP delivers specialised global investigation services to support corporate organisations, legal professionals, and private clients worldwide. With decades of international experience, advanced intelligence tools, and discreet investigative strategies, our teams provide accurate insights that enable you to make well-informed commercial or legal decisions, improving your chances of success.

Global Investigation Services

SIP has extensive experience supporting businesses and corporations in conducting investigations into extortion, protecting their brands and reputations, ensuring regulatory compliance, preventing financial losses from fraud and theft, uncovering facts about internal breaches and workplace misconduct, gathering competitor intelligence, and other investigation requirements. These investigations are crucial for effective corporate governance and risk management, particularly in complex, high-risk, or hybrid work environments.

White-collar crimes, such as money laundering, corruption, and sophisticated fraud and scams, are rapidly increasing, driven by digital advancement, work vulnerabilities, and economic instability. SIP investigates these cases daily, as it is one of our specialist areas, and our evidence has successfully identified those responsible for the crimes and helped recover multimillion-pound sums and other currencies, including those held in crypto accounts.

SIP is recognised by lawyers, bankers, and corporate professionals as a leading expert in global asset tracing and recovery support, leveraging its expertise to avoid common pitfalls in complex cross-jurisdictional enforcement.

Since 1983, SIP has handled thousands of private client cases. Objectives have included everything from finding a missing pet to investigating kidnappings, blackmail, and murder. Most cases involve checking a partner’s background, character, and fidelity during marriage; pre-marital checks for details on finances, employment, and reputation; due diligence for potential investments, partnerships, or threat assessments; and technical surveillance countermeasures (TSCM).

SIP has been gathering evidence for criminal defence from the initial CPS charges through pre-trial and post-trial appeals for decades. The intelligence we collect often results in the CPS dropping the initial charges, the Defendant being found not guilty, and those convicted being released after successful appeals.

Debtor and missing person tracing is a crucial service provided by SIP and used by a wide range of clients, from individuals and small businesses seeking to locate someone who has “gone off the grid,” absconded, or is deliberately avoiding contact due to debts or other reasons, to financial institutions and corporations needing to trace hundreds of former employees linked to pension schemes, among other matters.
