Post Alarm, a third-generation, family-owned provider of Southern California security services, announced the acquisition of Jadtec Security Services Inc.

The acquisition expands Post Alarm’s footprint in Southern California and unities two community-focused security providers with a shared commitment to protecting homes and businesses through advanced technology, responsive service, and local expertise.

“We are honored to welcome the Jadtec team and its loyal customer base into the Post Alarm family,” said Rob Post, president, Post Alarm. “Together, we’re strengthening our ability to provide faster service, broader support, and enhanced security offerings to clients throughout Southern California.”

Founded in 1956 by former Police Chief Sam Post, Post Alarm is now led by third-generation siblings Rob Post and Gina Post-Franco. Under their leadership, Post Alarm has experienced steady growth, including its 2023 acquisition of Peninsula Security in the South Bay/Palos Verdes and an expansion in 2024 into Santa Barbara/Montecito communities.

“We are excited about this new chapter for Post Alarm,” said Gina Post-Franco, vice president, Post Alarm. “The Jadtec team brings decades of trusted service to the table, and we’re committed to maintaining the personal, local approach their clients have come to expect, while introducing the added resources and technology that Post provides.”

Post Alarm now serves clients throughout Los Angeles, Ventura, Santa Barbara, Orange, Riverside, San Bernardino, and San Diego Counties with a full suite of security services, including:

• Intrusion and fire alarm systems
• Video surveillance
• Shield Services, Post's suite of live video monitoring and verification solutions
• Patrol and Armed Response
• Smart home/business automation
• 24/7 monitoring from its local TMA Five Diamond-certified central station

Through this partnership, Jadtec clients will gain:

• Access to faster service and installation windows via a larger team of local technicians
• Enhanced alarm monitoring via Post Alarm’s locally owned and operated central station
• Access to enhanced services aimed at providing proactive protection to layer onto their existing alarm service

Most of the Jadtec team will remain in place, providing continuity for clients and ensuring a smooth transition. The shared goal is to maintain the trusted relationships built over decades while expanding the services and support available to customers.

“We’re proud to unite with an organization that not only shares our values of integrity, responsiveness, and community-focused service but also understands the deep responsibility that comes with being a multi-generational, family-owned business,” said Jeri De Martini, former president, Jadtec. “As a second-generation company joining forces with a third-generation company like Post Alarm, we're confident this partnership will carry forward the pride, personal commitment, and high standard of care our clients have always relied on.”
