A Leading Enterprise-level Electronic Security Integrator

Access Systems Integration (Access SI) was established in 2000 with a commitment to deliver exceptional security systems integration solutions coupled with a unique-to-the-industry end-to-end customer service component.  The company was acquired by MSA Security in 2008, and was successful in expanding its product and service line, reaching new markets and expanding its footprint throughout the country.

In April of 2015 Access SI Founder and President Jim Hennessy led a management buyout of the company, and the company officially rebranded in September 2015, reverting back to its original name – Access Systems Integration.

“The carefully-planned company re-branding is meaningful – representing our enhanced commitment to our clients, and indicative of our aggressive plans for innovation and growth.”

Access SI President Jim Hennessy
