Only individuals and agencies holding a valid KDN licence under the Private Agencies Act 1971 (Akta 27) 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 27, and evidence gathered may be inadmissible in court.

Fees depend on case type, duration, and how many investigators are deployed. Straightforward services like background checks are often quoted as a fixed fee, while surveillance-based matrimonial or corporate cases are billed by time and duration. Optimal Security provides a free, no-obligation consultation and a written quote before any work begins.

No. Immigration entry-exit records are held exclusively by the Malaysian Immigration Department and other government agencies; licensed private investigators have no lawful access to this data. Be cautious of any agency that claims otherwise — it is a red flag for an unlicensed or non-compliant operator.

Yes. This is commonly searched in Chinese as  抓小三 or 婚外情取证. A licensed investigator conducts lawful surveillance in public spaces, documents patterns and evidence, and prepares a report usable in divorce or custody proceedings — without illegal wiretapping, device planting, or trespass, which would make evidence inadmissible and expose both investigator and client to legal risk.

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.

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.

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.

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.

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.

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.

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.
