Private Client Services
Since SIP International was founded in 1983, private clients have always been welcome to utilise our services, and we ensure they receive the personal attention their cases require. We recognise that the first step in contacting an investigation firm can sometimes be stressful, especially knowing they will need to discuss their personal lives and concerns with a stranger. Rest assured, our team will make every effort to help you feel comfortable when discussing these matters so we can understand your current situation and recommend the most economical and professional approach to achieving your objectives.
We have listed below some of the many services we offer to private clients. Therefore, if the investigative service you require is not mentioned, please still contact us as we are confident that we will have the solution.
Private Client Services We Provide
SIP delivers specialised global investigation services designed 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, asset recovery solutions, and strategic protection across complex cross-border matters.
Domestic Surveillance & Investigations
At SIP, we recognise that effective surveillance relies on highly skilled individuals with the experience and expertise to handle unpredictable situations while exercising discretion. Consequently, our specialist surveillance teams work seamlessly together to deliver the best possible outcomes. We have dedicated surveillance teams in the UK and the USA that are frequently deployed to support our global surveillance partners and ensure that surveillance aligns with the client’s objectives.
SIP surveillance services are provided for lawful reasons, often to gather evidence of links between the target and other individuals or organisations. In many business situations, it may be necessary when an employee is suspected of selling confidential information or trade secrets to a competitor, or involved in other white-collar crimes, thefts, proof of physical fitness due to fraudulent insurance claims, and similar offences. Likewise, in family matters, it can be required as proof of infidelity or concerns regarding a child’s welfare in custody disputes, among other circumstances.
At SIP, we recognise that your surveillance has unique objectives, so all tasks are carried out by a skilled team with a proven track record, and we are committed to securing any available evidence to meet your aims.
If you have a surveillance requirement, contact us today to discuss your case in the strictest confidence.
Missing Person & Debtor Trace
Although there is always a demand to locate a missing friend, family member, beneficiary, or debtor, tracing methods have advanced considerably since the 1990s, when our investigators would personally visit addresses and conduct door-to-door enquiries. Nowadays, SIP boasts a very high success rate thanks to sophisticated search technologies and data-mining techniques that enable us to track individuals and hard-to-find information buried deep within the hundreds of global public and subscriber databases we can access, as well as software tools and a team of expert research analysts capable of extracting data from the surface, deep, and dark web in a compliant manner. When necessary, SIP still has on-the-ground resources in most jurisdictions to verify a person’s location or to interview them for any other purpose the client may request.
We offer trace services to a wide range of clients, from individuals seeking to trace a single person to corporate clients and financial institutions that regularly instruct us to handle bulk traces, often exceeding 200 cases, due to our consistent success.
If you need to trace a person or multiple persons, contact us for a quotation.
Scam, Fraud Investigations
In March 2026, Interpol reported, “worldwide losses related to financial fraud in 2025 alone have been estimated at USD 442 billion.” In reality, this figure refers to cases that have been investigated; therefore, given the number of innocent people who have been scammed but feel ashamed or embarrassed to report it to the authorities, this figure is likely considerably higher.
SIP represents numerous lawyers and corporations when they require us to investigate complex frauds that often cross multiple jurisdictions. We also handle a large number of investigations for individuals who have suffered losses due to romance, investment, or impersonation scams. Because of the nature of these scams, we understand how traumatic and stressful they can be for private clients.Therefore, we have the patience to listen carefully and recommend a course of action that may help them recover their losses, provided we believe there is a reasonable chance of success.
SIP believes that individuals can greatly reduce the risk of falling victim to romance or investment scams by learning more about the person they are dealing with. This is why this website offers them the chance to purchase a social media and flag search from SIP to uncover detailed information about the individual, enabling a risk assessment before any serious commitment.
If you have been targeted by a scam or fraud, or if you are concerned that you might become one, contact us today.
Blackmail & Extortion Investigations
Nowadays, it is common for victims to be blackmailed over a past relationship, photographs taken while using drugs, or because someone has obtained confidential documents or data that could harm them. This results in the blackmailer making demands for money to prevent the release of images or private information in their possession to other parties or publishing them in the public domain.
We have observed a rapid increase in cases of Sextortion, where the client has engaged in an online romance or a casual one-time encounter, during which the victim is persuaded to perform a sexual act that is filmed or to provide explicit images. This is then followed by threats to share the media with the victim’s friends and family, or even to publish it online, unless demands are met, usually a substantial amount of money is paid into a cryptocurrency wallet.
There has also been an increase in extortion cases, which can range from stolen pets, artwork, or other valuables being taken with demands for their return, to more serious threats against a family member or property.
Clients turn to SIP for support when they prefer not to report incidents to the Police or other authorities, mainly because they are concerned about their identity and the details of the demands being leaked to the press. SIP has handled many cases of blackmail and extortion over the years, and several have been resolved satisfactorily for the client. As a result of perpetrators being identified through intelligence and surveillance resources, SIP then implements a strategic approach, which includes an exchange of carefully drafted “gagging” agreements that have been signed and securing the client’s property.
If you are a victim of blackmail or extortion, contact us for a confidential consultation.
Visa & Immigration Due Diligence
If you plan to apply for a visa or immigration status to the U.S. or many other countries around the world,applicants are generally required to provide usernames or handles for social media and other online platforms they have used within the past five years at the time of application.
We suggest taking a proactive step by instructing SIP to perform a pre-application due diligence check on you. This can help identify potential risks and notify you of possible delays or refusals in the application process. If the report is favourable, as our reports are independent, you might want to submit it with your application, as it could help to expedite the process.
The recommended extent of pre-application due diligence varies depending on the type of application being made, so contact us for further information.
