About MagnoSec Corp · Kissimmee, Florida
Florida's
Risk Management Group
Security officers, executive protection, fire watch, disaster response, investigations and digital risk under one leadership team. Led by a former UN Peacekeeper and federal task force investigator, advised by a retired NATO Lieutenant General. Built in Florida and growing through acquisition.
Who We Are
One company accountable for every layer of risk
Corporate and community risk is never just one thing. A company, a property or a community faces physical threats, internal fraud, emergencies and online exposure at the same time. Protecting them takes several services and divisions working together. MagnoSec brings them under one leadership team, so each client gets the combination it needs today and can integrate everything under one plan as it grows.
Our leadership learned risk management where the stakes were highest: UN peacekeeping in Haiti, antiterrorism deployments in Iraq and Afghanistan, federal investigations with a Homeland Security Investigations task force, and command at NATO. Today we apply that discipline to HOAs, hotels and resorts, apartment communities, construction sites, assisted living facilities, executives and their families, corporations and public agencies.
