KDN-Licensed Private Investigation Agency in Malaysia
Optimal Security Services Sdn. Bhd. is authorised by the Ministry of Home Affairs Malaysia (Kementerian Dalam Negeri / KDN) under KDN Lesen 2B — the agency-level private investigation licence governed by the Private Agencies Act 1971 (Akta 174). Every investigation we conduct is legally authorised, professionally documented, and produces evidence that is admissible in Malaysian courts.
What Is a KDN-Licensed Private Investigator?
A licensed private investigator (PI) in Malaysia is an individual or agency formally authorised by the KDN (Kementerian Dalam Negeri) under Akta 174 to conduct lawful surveillance, gather evidence, and produce investigation reports for legal, corporate, or personal purposes.
Akta 174 defines two PI licence categories: Lesen 2A — issued to individual investigators — and Lesen 2B — the agency licence. Optimal Security holds Lesen 2B, authorising us to field a coordinated team across multiple concurrent investigations anywhere in Malaysia.
Why You Must Only Engage a KDN-Licensed PI Agency
Engaging an unlicensed private investigator in Malaysia carries serious legal risk. Under Section 3 of the Private Agencies Act 1971 (Akta 174), operating as a PI without a KDN licence is a criminal offence — and any evidence gathered may be inadmissible in court. The client may also face liability for facilitating unlicensed activity.
A KDN Lesen 2B agency ensures every investigation is conducted within Malaysian law — producing documented, chain-of-custody compliant evidence accepted in civil litigation, employment tribunals, insurance disputes, and family court proceedings.

Why Optimal Security — Experience, Credentials & Legal Standing
Legally Licensed Under Malaysian Law
We hold KDN Lesen 2B under the Private Agencies Act 1971 (Akta 174) — the agency-level licence issued by Kementerian Dalam Negeri (KDN). This is not a business registration; it is a specific investigative licence granted only after regulatory vetting. You can verify our licence directly with the Ministry of Home Affairs.
Evidence That Holds Up in Court
Our investigators are trained in chain-of-custody documentation, evidence handling protocols, and report preparation to Malaysian legal standards. Reports produced by our team have been used in civil litigation, employment tribunals, family court proceedings, and insurance dispute resolutions.
Specialists Across Investigation Disciplines
Our team includes investigators with backgrounds in corporate compliance, law enforcement, human resources, and insurance. This means your case is assigned to an investigator with relevant domain experience — not a generalist operative.

Private Investigator Malaysia — Frequently Asked Questions (2026)
Answers to common questions about hiring a KDN-licensed private investigator in Malaysia, covering legal authority, investigative methods, evidence admissibility, and confidentiality under the Private Agencies Act 1971 (Akta 174).
Who can legally operate as a private investigator in Malaysia?
Only individuals and agencies holding a valid KDN licence under the Private Agencies Act 1971 (Akta 174) may lawfully operate as private investigators in Malaysia. Individual investigators require a Lesen 2A; agencies require a Lesen 2B. Operating without a licence is a criminal offence under Section 3 of Akta 174, and evidence gathered may be inadmissible in court.
What is the difference between KDN Lesen 2A and Lesen 2B?
Lesen 2A is issued to an individual private investigator. Lesen 2B is the agency-level licence, authorising a company to employ and deploy multiple investigators across concurrent cases. Optimal Security Services Sdn. Bhd. holds Lesen 2B, enabling a coordinated team for complex, multi-location investigations.
What services do licensed private investigators provide in Malaysia?
Licensed agencies handle corporate fraud and financial misconduct investigations, employee misconduct and workplace surveillance, matrimonial and infidelity investigations, insurance claim verification, background screening and due diligence, asset tracing, witness location, and covert surveillance with documented evidence.
Is evidence collected by a private investigator admissible in Malaysian courts?
Yes — evidence gathered by a KDN-licensed private investigator using lawful methods and a documented chain of custody is admissible in Malaysian civil and criminal proceedings. Evidence from an unlicensed operative or illegal surveillance is not admissible and may expose both investigator and client to criminal liability.
Can a private investigator conduct matrimonial or infidelity investigations in Malaysia?
Yes. A KDN-licensed investigator can conduct discreet surveillance of a spouse or partner, document activities with photographic and video evidence, and produce a formal report that is court-admissible for divorce proceedings, custody disputes, and family court hearings.
How much does a private investigator cost in Malaysia?
Fees vary based on case type, duration, the number of investigators deployed, and geographic scope. Matrimonial surveillance, corporate fraud investigations, and multi-state asset tracing each carry different cost structures. Most licensed agencies, including Optimal Security, provide a free initial consultation before issuing a quote.
Are private investigators allowed to use GPS tracking and surveillance equipment in Malaysia?
Licensed investigators may use legal surveillance equipment, cameras, and GPS tracking within the bounds of Malaysian law and a lawful engagement. Unauthorised device placement on another person's property or illegal interception of communications is prohibited regardless of licensing status.
How do I verify a private investigator's licence in Malaysia?
You can verify a PI agency's licence with the Ministry of Home Affairs Malaysia (Kementerian Dalam Negeri). A legitimate agency should display its licence certificate and provide its Lesen 2B number on request. Optimal Security displays its licence certificate publicly and on request.
How confidential is a private investigation in Malaysia?
Licensed agencies operate under strict confidentiality protocols. Your identity, case details, and gathered evidence are shared only with you or your legal representatives, using secure communication channels and document storage throughout the investigation.
How long does a private investigation take in Malaysia?
Timelines depend on case type. Background checks and verification can often be completed within days, while surveillance-based matrimonial or corporate fraud cases typically run from one to several weeks depending on the patterns being documented.
What happens after a private investigation is complete?
You receive a written investigation report with supporting evidence, delivered only to you or your nominated legal representative. The report can then be used for legal proceedings, HR decisions, or your own personal record.
