Private Security Is Now a $50 Billion Industry and Growing Fast

A Booming Business Built on Fear and Uncertainty

Revenue in the private security sector climbed 17% over the past decade to above $50 billion in 2025, according to Robert H. Perry & Associates. That figure reflects something profound about the state of American society — a growing, collective sense that safety can no longer be taken for granted, even in the most ordinary settings.

As political and cultural tensions have hit a boiling point in the U.S., even pockets of American life once considered mundane feel at risk of becoming scenes of violence. "Who would have thought 10 years ago that you would need to hire private security at a school board meeting or at a town meeting," said Steve Amitay, executive director of the National Association of Security Companies. That shift in perception — from security as a luxury to security as a necessity — is what's driving billions of dollars into a sector that barely registered in most people's thinking a generation ago.

The Giant at the Center of It All

At the heart of the personal protection boom is Allied Universal, a privately held company with operations in more than 100 countries and annual revenue of about $23 billion. Guards donning Allied Universal's uniforms oversee lines, operate metal detectors and inspect bags at sporting events, music festivals and office buildings. The company's reach is staggering — almost invisible in its ubiquity, yet present at nearly every large gathering Americans attend.

Allied lists more than 80% of Fortune 500 companies among its clients and has supported globally important events such as this summer's World Cup. CEO Steve Jones has publicly shared his ambitions to take the company public. Allied said in a statement that "we continue to assess how the company is capitalized" and that its focus is currently on expanding the business and serving customers.

From Neighborhoods to Houses of Worship

San Diego's Hillcrest neighborhood became a flashpoint after violent acts and hate crimes. In response, members of the Hillcrest Business Association in 2024 began funding third-party unarmed patrols, budgeting about $400,000 per year for eight hours a day. The group plans to add about $150,000 next year to cover a second shift. It's a pattern playing out in communities across the country — local organizations making hard financial decisions to create a visible sense of order and safety.

The stakes couldn't be higher, as one Michigan congregation recently demonstrated. In March, an attacker drove into a metro Detroit synagogue that was filled with children. Its in-house security staff mobilized within seconds, and none of its community members were killed. Leaders at Temple Israel hailed the guards as heroes. "It is a miracle that they kept everybody as safe as they did," said Andy Bocknek, the temple's past president. "Had we not had people who were so committed to the institution, to the people that they see every day, I can't even imagine what this may have looked like."

A Labor Market Transformed

Nearly 1.3 million Americans worked as security guards in May 2025, an increase of around 16% from 2016, according to Bureau of Labor Statistics data. That makes private security one of the more quietly significant employment stories in the modern American economy — a workforce larger than many industries that receive far more attention.

Corporations increasingly operate in an environment where reputational damage can spread instantly, employees expect safer workplaces, customers demand protection, and a single high-profile incident can generate enormous financial consequences. That makes security spending increasingly difficult for businesses to treat as optional. The result is an expanding private security economy built around a simple proposition: companies may not be able to eliminate risk, but they are increasingly willing to pay to manage it — and that could make private security one of the most important growth industries in America's evolving public-safety economy. Whether that trend reflects a society growing smarter about risk management, or one growing more anxious about its own fractures, may be the more uncomfortable question worth asking.
