Public Security

What Public Security does

Public Security LLC is a private security and investigation firm headquartered in Chester, Maryland, founded in 2013 by Barry Donadio, a former U.S. Secret Service agent who served at the White House protecting Presidents George W. Bush and Barack Obama. The company provides armed and unarmed security guards, executive protection, private investigations, drone surveillance patrols, fire watch services, and wedding and event security, operating across Maryland and New York and serving the Washington D.C. metropolitan area and Long Island. In February 2026, the company was designated a Special Police Agency in Maryland, granting its officers police powers and arrest authority on client properties — a legal status unavailable to standard security guard companies. The firm is a U.S. Government Contractor (CAGE Code #72SY5) and is registered under CISA's Emergency Services Sector as part of the Federal Critical Infrastructure designation.

The company monetizes through three revenue streams: security services priced per incident or ongoing contract (executive protection, event security, residential patrols, fire watch); firearms and tactical training (HQL at $150, Wear & Carry 16-hour at $600, ASP Baton at $100, private firearms training at $125/hour); and private investigation services (surveillance, criminal/civil cases, court testimony). Distribution runs through direct phone sales (855-589-2267), website bookings, SAM.gov federal contracting, and an on-call, no-contract-required model that targets both enterprise clients (politicians, schools, churches, businesses) and individual consumers (wedding parties, training students). Customer segments include Members of Congress and Presidential candidates, schools and places of worship, event organizers, wedding parties, residential communities, and municipalities supplementing police services.

Supporting the operations is a Security Academy that delivers 12-hour Maryland-mandated guard training and a full suite of firearms certification courses taught by Donadio at partnered facilities (American Legion Post 278 in Stevensville and Schrader's Outdoors in Henderson, Maryland). The company maintains seven physical offices across Maryland and New York, a workforce drawn from off-duty and retired police, military veterans, and former federal agents, and a multi-channel digital presence including a website, social media, earned media via Donadio's 80+ TV appearances, and partner platforms like WeddingWire, Nextdoor, and Alignable.

Expansion highlights6 records

Broad incumbents

• Kroll: Global security consulting and investigations firm offering executive protection, cyber, and due diligence. Overlaps with Public Security's private investigations, executive protection, and national security consulting lines, but at significantly broader enterprise scale.
• Allied Universal: Largest U.S. manned guarding and security services provider offering armed/unarmed guards, event security, and patrol services. Overlaps with Public Security's manned guarding and event security offerings, but lacks the executive protection specialization and Special Police designation.
• Pinkerton (a Securitas company): Iconic investigative and corporate security provider offering executive protection, investigations, and security consulting globally. Comparable to Public Security across investigations and protective services, but operates at much larger scale as part of Securitas.
• Hillard Heintze (part of Securitas): Corporate security risk management firm providing executive protection, investigations, and security consulting. Comparable to Public Security's national security consulting and protective services, with broader Fortune 500 client base.
• Securitas USA: Major security services provider with guarding, protective services, and security consulting. Comparable to Public Security's broader security services portfolio, but at national scale and without the boutique Congressional protection positioning.

Direct peers

• USPA Nationwide Security: Multi-state licensed private security and executive protection firm offering armed guards, VIP protection, and investigations. Directly comparable to Public Security's full-service security, executive protection, and investigations stack across Maryland and New York.
• MVM Inc. U.S. security and investigative services firm focused on protective services, law enforcement support, and government contracts. Comparable to Public Security's government contractor positioning (CAGE Code, CISA) and protective detail work for federal clients.
• Gavin de Becker & Associates: Premier U.S. executive protection and threat assessment firm built around a high-profile founder. Directly comparable to Public Security's protective detail model for politicians, celebrities, and high-net-worth individuals, with similar Secret Service-grade positioning.
• AS Solution (ARC / CriticalMention): Boutique executive protection firm focused on close protection and protective intelligence for corporate and high-net-worth clients. Closely matches Public Security's premium protective detail offering for high-profile individuals and corporate executives.

Regional players

• Walden Security: Regional U.S. security guard and protective services firm with multi-state operations. Comparable to Public Security's manned guarding and fire watch offerings across the Mid-Atlantic, though less specialized in executive protection.
