Laws on Private Security and Detective Agencies
The controlling statute
RA 11917, the Private Security Services Industry Act, is the current framework for private security and detective agencies; it repealed RA 5487. The PNP-SOSIA administers licensing and regulation under the statute and its implementing rules. Candidates must distinguish the agency license to operate from the individual license to exercise the security profession. A detective agency may not lawfully contract for or deploy personnel without the required agency license, and each detective or security professional must hold a valid individual license and comply with training, identification, uniform, firearm, and permit requirements. The IRR supplies procedural details: applications, qualifications, fees, bonds, training standards, and grounds for suspension or revocation.
Common traps
A frequent exam trap is treating RA 5487 as still the primary law; after RA 11917 it is repealed, though older concepts may appear in transition questions. Another trap is assuming a private detective has police authority. A detective is a private citizen who may act only within law, including citizen's arrest and lawful evidence gathering; he cannot search a home without consent or legal process, wiretap, or detain a person at will. Do not confuse a company's business registration with a PNP-SOSIA license, or a guard's company ID with a professional license.
Rule of thumb
License the entity, license the person, then authorize the post: agency LTO, individual license, and client contract/post orders must all exist before deployment. If one is missing, treat the operation as unlicensed and flag administrative and criminal exposure.
