Questions people ask first
What does Ranger Investigation & Security Services do?
Ranger is a Singapore company licensed by the Singapore Police Force, organised into three business lines. Private Investigation handles matrimonial, family, background, corporate, litigation and bug-sweeping (TSCM) matters. Security Solutions provides licensed security officers, mobile patrols, event security, executive protection and integrated remote monitoring.

Who do I contact for each business line?

Why choose one company for investigation, security and technology?
Many situations need both fact-finding and protection — for example, suspected internal theft followed by tighter site security, or a harassment case that needs evidence and a safety plan. One provider across investigation, manpower and technology means continuity, no hand-over gaps and a more coordinated response.
Is it legal to hire a private investigator or security agency in Singapore?
Yes. It is legal to engage a properly licensed private investigation agency or security agency in Singapore. Ranger holds Private Investigation Agency Licence L/PS/000759/2025 and Security Agency Licence L/SA/2026/000052, and works strictly within Singapore law.
Will my enquiry be kept confidential?
Yes. Every enquiry starts with a confidential, no-obligation discussion. Personal and corporate matters are handled discreetly and in line with the Personal Data Protection Act (PDPA).
Where is Ranger located?
Our office is at 808 French Road, #07-183, Kitchener Complex, Singapore 200808 — near Lavender and Bendemeer MRT stations. We serve clients across all of Singapore and, through licensed partner agencies, overseas.
