Established on June 5, 1968, Sentinel Integrated Security Services, Inc. is a proudly Filipino-owned corporation and one of the country's most established private security providers. Originally serving as the exclusive security partner of San Miguel Corporation, Sentinel has evolved into a trusted provider of comprehensive security solutions for local and international clients nationwide.
Backed by 58 years of industry experience, Sentinel is built on a foundation of integrity, professionalism, discipline, and operational excellence. The company delivers reliable, client-focused security strategies through the deployment of licensed, highly trained, and carefully screened personnel committed to protecting people, assets, and operations with the highest standards of accountability and service.
The company was founded by Col. Jose P. Rueda, a decorated military officer and former Security Director of San Miguel Corporation. A top graduate of the Philippine Constabulary Academy in 1924, Col. Rueda served in World War II — notably as part of the security escort to Gen. Douglas MacArthur in Leyte in 1942.
His dedication to service extended beyond the battlefield — supporting Malacañang Palace, foreign dignitaries, and multinational investors. In 1968, Sentinel Watchman and Protective Agency was officially entrusted to his leadership.
Now in its third and fourth generation of leadership, the Manotok family continues to uphold Col. Rueda's founding values: service, honor, and the dignity of security professionals.
Our organization is driven by a commitment to human resource development, continuous training, and performance-based management. With decades of experience serving both legacy and multinational clients, Sentinel maintains a reputation built on credibility, discretion, and consistent quality.
We balance tradition with innovation to deliver trusted protection for people, property, and reputation — combining field expertise with strategic insight to address evolving security needs.
