At the International Investigators Network (IIN), we firmly believe that prevention is always better than dealing with the consequences. Since our establishment in 2002, we have been guided by this philosophy. Originally the investigation arm of Vigilant Security & Investigation Services (Pvt) Ltd., a pioneering industrial security company established in 1973, IIN was formed as an independent unit to address the gap in the investigation sector in Sri Lanka.

While we are based in Colombo, our investigative services are not limited to the city. Through our extensive network of partner investigators across the globe, we offer our services throughout the island and beyond.

With a strong commitment to excellence, we are proud members of the Council of International Investigators (CII) and the Professional Background Screening Associations (PBSA) APAC Chapter. These affiliations connect us to a global network of experienced investigators and allow us to stay up-to-date with industry standards and best practices.

We take pride in our ISO 9001:2015 certification, which highlights our commitment to quality and continuous improvement in our services.

Over the years, IIN has earned the trust and loyalty of a diverse client base, which includes leading insurance companies, law firms, blue-chip companies, medium to small-scale businesses, and private clients. Our ability to efficiently solve investigations while maintaining anonymity, confidentiality, and quick turnaround times has been instrumental in building strong relationships.

Additionally, investigation companies from the US, Europe, and Asian regions choose IIN as their trusted partner for scrutinizing, fact-finding, and inspection.

At IIN, we are dedicated to providing reliable and effective investigation solutions to meet the diverse needs of our clients while upholding the highest standards of professionalism and confidentiality.
