Good — I can help. Below I’ll (1) show how to find and verify licensed security (guard/investigation) firms in Malaysia using the official regulator, (2) list a few established companies you can contact, and (3) give a short checklist of what to confirm before hiring.

1. Official way to find and verify licensed private security agencies

• Private security and private investigation agencies in Malaysia are licensed under the Private Agencies Act 1971 and regulated by the Ministry of Home Affairs (Kementerian Dalam Negeri, KDN). The KDN website explains licensing types, requirements and provides a system to check agency licences and security vetting. (moha.gov.my)
• Action to take: ask any provider for their KDN licence number and then verify it using the KDN “Sistem Semakan Lesen Agensi Persendirian” (or by contacting the Security & Public Order Division, Ministry of Home Affairs). The KDN pages list licence requirements (capital, shareholder requirements, permitted activities) so you know what a lawful licence looks like. (moha.gov.my)

2. Examples of established security firms (to consider contacting) Below are reputable, widely known security-service companies that operate in Malaysia or the region. I’m listing them as starting points — always verify each firm’s current KDN licence, service scope, contract terms and references before hiring.

• Safeguards / G4S (Malaysia) — operates security guards, electronic security, central monitoring and training academies in Malaysia. (Search results and company profiles show active operations in Malaysia.) (malaysia-canada.com)
• Prosegur — global security group offering guarding, alarms, cash-in-transit and hybrid security services; has global and regional presence and offers local security solutions. Confirm local Malaysia presence and licence for any local branch/partner. (Prosegur.com)

(If you’d like, I can compile more locally-focused names — there are many local private agencies across Peninsular Malaysia and East Malaysia — but because licences and company status change, it’s best to verify each via KDN before engagement.)

3. Quick checklist before hiring a security firm

• KDN licence number: request it and verify on the Ministry of Home Affairs system. (moha.gov.my)
• Scope of licence: confirm they are licensed for the service you need (guarding, personal protection, private investigation, electronic monitoring, cash services, etc.). (moha.gov.my)
• Insurance: public liability and employer liability for guards.
• Personnel vetting & training: ask about their vetting process, whether guards undergo KDN security vetting and what training/certificates they hold.
• Contract terms & pricing: clear scope, response times, supervision, replacement policy, termination clauses.
• References & site visits: get client references and (if possible) visit a current client site or the firm’s operations/monitoring centre.
• Local presence & backup: ensure they have supervisors in your area and a 24/7 control/response capability (important for alarm monitoring and rapid response).

If you want, I can:

• Look up and compile a short list (5–10) of licensed private agencies in a specific Malaysian state or city (e.g., Kuala Lumpur, Penang, Johor Bahru) and include their KDN licence status where available (I’ll verify each via KDN and company sites). This requires a brief web search — shall I proceed and focus on a particular location or service type?
