The Security Guard Shortage: Why Turnover Is Accelerating the Shift to Automation

The United States private security industry is facing a structural labor crisis that shows no signs of resolving. With 1.2 million security guards employed nationally (Bureau of Labor Statistics, 2024) and 162,300 annual job openings — almost entirely replacement positions driven by turnover rather than growth — guard companies are running on a perpetual recruitment treadmill that is degrading service quality across the industry.

For commercial property owners, construction companies, campus administrators, and facility managers who rely on manned guarding, this is not an abstract workforce trend. It is an operational reality affecting the security coverage they are receiving today: guards who are unfamiliar with their assigned properties, rising billing rates that are not accompanied by rising performance, and coverage gaps when shifts go unfilled.

This article examines the security guard shortage with current data, analyzes what is driving it, and explains why the structural nature of the problem makes it likely to persist — accelerating the transition to automated security technology that is already underway across the industry.

The Data Behind the Security Guard Shortage

The Bureau of Labor Statistics' Occupational Outlook Handbook projects 0% net employment growth for security guards through 2034 — yet the industry will generate 162,300 openings annually over the same period. This apparent contradiction resolves when you understand the driver: annual openings are overwhelmingly driven by turnover replacement, not growth. The industry is not expanding meaningfully; it is simply trying to replace the guards it loses every year.

The Turnover Numbers

Average annual turnover: 100–300% across the industry (IBISWorld, 2024) — many guard companies replace their entire workforce every year
Industry context: The security services sector had a turnover rate of 77.0% in 2024, compared to the pre-pandemic rate of 69.3% in 2019 (UC Berkeley Labor Center, August 2025)
Comparison to private sector: Overall private sector turnover in comparable markets was 58.1% in 2024 — security guard turnover is 33% higher than the private sector average
Annual openings: 162,300 guard openings annually — one of the largest replacement-driven opening volumes of any occupation in the BLS database

The Wage Reality

The median annual wage for security guards nationally is $38,370 ($18.46/hour) according to the Bureau of Labor Statistics (2024). In the New York City area, a 2025 UC Berkeley Labor Center analysis found that the median security guard wage represents less than 40% of the Area Median Income — qualifying guards as very low-income for affordable housing purposes. When wages do not cover basic living costs in the markets where guards are needed most, turnover is the inevitable result.

The wage situation has a compounding effect: guard companies facing labor shortages raise wages to attract workers, which drives billing rates higher for clients. The 2024 Annual Guarding Report from Security Magazine identified rising hourly pay rates (cited by 61% of respondents) and labor shortage (52%) as the primary operational challenges facing the industry. Higher billing rates without improved performance is the worst-case outcome for buyers of guard services.

What Is Driving the Shortage

Wage Competition from Other Industries

Security guard wages have remained essentially flat in real terms for two decades, while the cost of living — particularly housing — has risen significantly. A 2025 Center for American Progress analysis found that the median security guard in 2022 earned two cents per hour less (in inflation-adjusted terms) than in 2003, while rent costs grew 14.3% over the same period. When warehouse work, delivery driving, and retail roles pay comparable wages with less responsibility and better hours, security becomes a difficult recruiting proposition.

Working Conditions

Security guard work involves overnight shifts, holiday duty, solo positions in isolated or high-risk environments, and the psychological burden of being the first responder to potentially dangerous situations — all for wages that do not reflect these demands. The mismatch between job demands and compensation is a primary driver of both the turnover rate and the recruitment difficulty.

Aging Workforce

The average age of an employed security guard in the United States is 43 years old (Belfry, 2025). An older workforce is more prone to health-related attrition and less likely to fill the physically demanding aspects of the role. As older guards retire or exit, they are being replaced by a smaller pool of willing younger workers at an industry that has not invested sufficiently in the career development and compensation structures needed to make guarding an attractive long-term occupation.

How the Shortage Affects Security Quality

The guard shortage does not just create coverage gaps — it degrades the quality of the coverage that is provided:

Unfamiliarity with assigned properties: High turnover means guards are frequently assigned to properties they have never patrolled. Site-specific knowledge — knowing which areas are high-risk, where authorized vehicles park, which entrances are normally secured — takes weeks to develop and is lost every time a guard turns over
Training inadequacy: Guard companies facing constant replacement pressure reduce training to get workers deployed faster, compressing the training that would otherwise build the judgment and protocol knowledge effective guarding requires
Shift coverage gaps: When guards call in sick or quit without notice, companies must fill shifts with whoever is available — frequently untrained temporary workers who do not know the property or the client's protocols
Fatigue effects: Guards covering overtime shifts to compensate for understaffing are more fatigued and less alert — particularly during the overnight hours when most incidents occur
Morale and engagement: Guards who know they are undervalued and underpaid are less invested in the job — and less likely to perform the vigilant observation that effective guarding requires

The Structural Shift to Automated Security

The guard shortage is accelerating an industry transition that was already underway: the shift from labor-intensive manned guarding toward automated security technology. The economics are clear — a robotic patrol system costs $7–$11 per service hour compared to $25–$45 per hour for a fully burdened guard, with superior coverage consistency, zero fatigue, and no turnover.

This is not a prediction — it is a description of what is happening in the market right now. The global security robot market is projected to reach $4 billion by 2027, up from $785 million in 2020, according to Allied Market Research. Drone-as-a-Service security deployments are growing at double-digit annual rates. Remote Security Operations Centers are expanding their client portfolios as guard companies struggle to staff accounts.

The guard shortage has clarified the strategic question for security buyers: continue paying more for less reliable human coverage, or invest in automated systems that deliver better performance at lower total cost? An increasing number of property owners, construction companies, and campus operators are choosing the latter.

The Hybrid Model: Where Guards Still Matter

The transition to automated security does not mean guards become obsolete. Functions requiring physical presence — access control gates where manual credential verification is required, customer-facing reception security, physical incident response when law enforcement is delayed — remain appropriate for human guards. The emerging model deploys guards in their genuine areas of advantage while replacing the overnight patrol, wide-area surveillance, and perimeter monitoring functions with automated systems that outperform guards in those roles.

For clients currently spending 80% of their guard budget on overnight patrol functions, a hybrid model — RSOC-connected drones and robotic patrol for overnight coverage, guards for daytime access control — typically reduces security cost by 40–60% while improving coverage quality during the highest-risk overnight window.

How DSP Addresses This Challenge

DSP's Physical Security as a Service model replaces the staffing dependencies and turnover costs of traditional guard services with autonomous drone patrol, robotic units, and 24/7 RSOC monitoring — delivering consistent coverage at a predictable monthly cost.

Frequently Asked Questions: The Security Guard Shortage

Why is there a security guard shortage?

The security guard shortage is driven by a combination of wage stagnation (median guard wages have been essentially flat in real terms since 2003 per CAP analysis), demanding working conditions (overnight shifts, isolated positions, high-risk environments), intense competition from better-paying industries, and an industry structure that has underinvested in career development and compensation. The result is 100–300% annual turnover at many guard companies, creating a perpetual replacement cycle that cannot keep pace with demand.

How does guard turnover affect the security I'm receiving?

High guard turnover means the person patrolling your property tonight may have been assigned there for the first time — without site-specific knowledge, without familiarity with your protocols, and without the established situational awareness that effective guarding requires. It also increases the probability of shift coverage gaps when turnover creates unfilled positions, and reduces the quality of the security presence during the critical overnight hours when guard fatigue and motivation are at their lowest.

Is automated security a real alternative to security guards?

For the functions where guards perform least reliably — overnight patrol, wide-area perimeter surveillance, consistent monitoring of large outdoor spaces — automated security technology is a demonstrably superior alternative at lower cost. Drones, robotic patrol systems, and RSOC monitoring deliver consistent, documented coverage without fatigue, turnover, or the wage escalation pressure that is making guard services increasingly expensive. For functions requiring physical presence and human judgment, guards remain the appropriate choice — but those functions represent a minority of typical guard contract hours.

Will security robots replace all security guards?

No — but they are replacing the specific functions where guards add the least value and perform least reliably. The industry consensus, reflected in BLS employment projections (0% net growth through 2034), is that technology augments rather than eliminates the guard workforce. What is changing is the ratio: the optimal security program in 2026 uses significantly fewer guards — deployed for their genuine strengths — supported by significantly more technology than programs designed five or ten years ago.
