Who regulates and registers private security companies?

DIGESSP (the General Directorate of Private Security Services), a unit of the Ministry of the Interior (Gobernación) founded on May 2, 2011, authorizes entities and issues licenses (series A/B/H) and agent credentials. Its register of entities (a 56-page PDF) publishes, for each company: corporate name, trade name, legal representative, address, license number, and issue and expiry dates, a direct input for vetting a supplier before contracting.
