Our story
Built on training, accountability, and performance
American Alliance Security Agency was founded in Manchester, New Hampshire in 2018 with a simple objective: provide clients with trained, accountable security professionals. Here is how we have grown since.

2018–2019 Building the Foundation
Founded in Manchester, New Hampshire, in 2018, American Alliance Security Agency began with unarmed and temporary security coverage for local businesses. Training, accountability, and professional service shaped our approach from the beginning.
As our client base grew, we added armed security, executive protection, and mobile patrol to meet a wider range of security needs.

2020 Adapting to Changing Needs
The COVID-19 pandemic brought sudden changes to the properties and businesses we served. We adapted our security coverage to meet changing site requirements and support our clients’ daily operations.
Throughout that uncertainty, our focus remained on dependable staffing, clear communication, and responsive service.

2021 Strengthening the Organization
Formal incorporation in 2021 marked an important step in the company’s development. Building on our first three years, we continued developing long-term relationships with commercial clients, government agencies, and national organizations.
-
2022–2023 Expanding Our Regional Presence
With offices opening in Somerville and Boston, Massachusetts, we began supporting clients in more communities. New government contracts in New Hampshire also expanded our public-sector work.
During this period, our services reached more healthcare, education, residential, retail, and industrial settings, each with its own day-to-day security requirements.

2024 Recognition for Our Service
In 2024, we were named Best Security Guard Service in Manchester, New Hampshire, by Business Rate.
The recognition marked a milestone for our team and the service we provided to local businesses and communities.
-
2025–2026 Expanding in New Hampshire
The opening of our Nashua, New Hampshire, office added another local base for our operations. We were again named Manchester’s Best Security Guard Service by Business Rate in 2025 and 2026, marking three consecutive years of recognition.
As we take on new assignments, our priorities remain the same: prepare our people, remain accountable to our clients, and provide dependable security service.
