7 Workplace Security Risks and How to Prevent Them

Most organizations discover their workplace security risks the hard way - after an incident reveals a vulnerability that should have been identified and addressed months earlier. The unauthorized visitor who walks through the lobby unchallenged. The former employee whose badge still opens the server room. The emergency exit that has been propped open with a brick since last summer.

Workplace security risks are conditions, behaviors, or gaps in an organization’s protective measures that create the potential for harm to people, property, information, or operations. They are not theoretical - they are specific, identifiable, and preventable.

Definition: Workplace security risks are vulnerabilities in an organization’s physical, digital, personnel, or procedural security posture that could be exploited - intentionally or accidentally - to cause harm, loss, or disruption. Identifying and mitigating these risks is the foundation of any effective security program.

According to the Bureau of Labor Statistics and ASIS International’s 2025 Workplace Security Benchmark Report, organizations that conduct formal risk assessments experience 41% fewer security incidents than those that rely on informal or ad-hoc evaluations. The reason is straightforward: you cannot prevent what you have not identified.

This guide examines the seven most common workplace security risks, provides a framework for assessing them, and outlines prevention strategies that work. For the complete strategic picture, visit our workplace security management hub.

Why Understanding Security Risks Matters

Workplace security risks exist on a spectrum. Some are obvious - a broken lock on a ground-floor window. Others are subtle - a visitor check-in process that collects names but never verifies identities. The subtle ones are more dangerous because they persist undetected for longer periods.

Understanding workplace security risks matters for three reasons:

• Prevention is cheaper than response. Fixing a vulnerability costs a fraction of what it costs to manage an incident. The average cost of a workplace security incident involving unauthorized access exceeds $38,000 when legal, investigation, remediation, and productivity losses are included.
• Legal and regulatory obligations require it. OSHA, GDPR, ISO 27001, and industry-specific regulations mandate that organizations identify and mitigate security risks. Failure to do so creates liability.
• People expect it. Employees, visitors, and clients expect that the places they work and visit have been assessed for security risks. When an incident occurs because a known risk was ignored, trust - the foundation of every workplace relationship - erodes.

Knowing what workplace security is provides the conceptual foundation. This guide provides the practical application: here are the specific workplace security risks you need to find and fix.

The 7 Major Workplace Security Risks

1. Unauthorized Access and Tailgating

The risk: Individuals entering secured areas without valid credentials. Tailgating - following an authorized person through a controlled entrance - is the most common method. Others include using cloned or stolen badges, exploiting propped-open doors, and entering through unmonitored entrances.

Why it matters: Unauthorized access is the gateway risk. Nearly every other workplace security risk - theft, violence, data breaches - requires physical access as a prerequisite. If unauthorized individuals can enter freely, no other security measure is effective.

Prevention strategies:

• Deploy anti-tailgating measures at critical entry points (turnstiles, mantraps, guard verification)
• Implement digital visitor management that verifies identity before granting access
• Conduct regular access audits to deactivate credentials of former employees and expired contractors
• Install sensors or cameras at emergency exits to detect propped doors
• Train employees to challenge unfamiliar faces politely but consistently

2. Inadequate Visitor Tracking

The risk: Visitors - clients, vendors, delivery personnel, interview candidates - enter the facility with no record of who they are, where they went, when they arrived, or when they left. Paper logbooks, when they exist, contain illegible handwriting, incomplete entries, and no verification.

Why it matters: Without accurate visitor tracking, you cannot determine who was in the building during an incident. You cannot verify that all visitors have exited during an emergency. You cannot demonstrate compliance with data protection or safety regulations.

Prevention strategies:

• Replace paper logbooks with a digital visitor management system that captures verified identity data
• Require photo ID verification for all visitors
• Issue temporary badges with visible expiration indicators
• Implement host notification so every visitor is expected and accounted for
• Maintain digital records for compliance audits - see our visitor log compliance audit guide for details

3. Employee Theft and Insider Threats

The risk: The threat that comes from inside the organization. Employee theft accounts for an estimated $50 billion in annual losses in the United States alone, according to the U.S. Chamber of Commerce. Insider threats extend beyond theft to include sabotage, data exfiltration, and policy violations.

Why it matters: Insiders have legitimate access, knowledge of security measures, and understanding of valuable assets. They can bypass controls that stop external threats entirely. Workplace security risks from insiders are harder to detect and often cause more damage per incident.

Prevention strategies:

• Implement the principle of least privilege - employees access only what they need for their role
• Conduct background checks during hiring and periodically thereafter
• Deploy access logging that creates an audit trail for sensitive areas
• Establish anonymous reporting channels for employees to flag concerns
• Monitor for behavioral indicators (sudden after-hours access, accessing areas outside normal scope)

4. Data Breaches Through Physical Access

The risk: Information security failures that originate from physical access - stolen laptops, unauthorized access to server rooms, shoulder surfing in open offices, dumpster diving through improperly shredded documents, or visitors viewing confidential screens.

Why it matters: Data breach costs continue to rise. IBM’s 2025 Cost of a Data Breach Report places the average at $4.88 million. Many breaches that are classified as “cyber” have a physical access component that enabled the initial compromise.

Prevention strategies:

• Secure server rooms, network closets, and data centers with multi-factor access control
• Implement clean desk policies and enforce them through regular audits
• Deploy privacy screens on monitors in client-facing or open areas
• Require encryption on all laptops and mobile devices
• Control physical access to IT infrastructure as carefully as you control digital access

5. Workplace Violence

The risk: Any act or threat of physical violence, harassment, intimidation, or other threatening behavior that occurs at the workplace. This includes violence by coworkers, clients, visitors, domestic partners who enter the workplace, and former employees.

Why it matters: Workplace violence affects nearly 2 million American workers annually, according to OSHA. Beyond the obvious human cost, workplace security risks related to violence create lasting psychological impact on witnesses, legal liability for the organization, and reputational damage.

Prevention strategies:

• Establish a zero-tolerance policy for threats and violent behavior
• Train managers to recognize warning signs and escalation patterns
• Create clear reporting mechanisms that employees trust to be confidential
• Implement pre-employment screening that includes criminal background checks
• Develop a workplace security incident response plan that specifically addresses violence scenarios
• Control visitor access to prevent unauthorized individuals from reaching employees

6. Emergency Preparedness Gaps

The risk: The organization is unprepared for emergencies - fire, natural disaster, active shooter, medical crisis, utility failure - that require rapid, coordinated response. Emergency plans are outdated, exits are blocked, drills are infrequent, and roles are undefined.

Why it matters: Emergencies expose every weakness in an organization’s security posture simultaneously. Workplace security risks related to preparedness gaps compound rapidly under pressure. A fire evacuation that does not account for visitors on-site becomes a life-safety crisis.

Prevention strategies:

• Maintain current emergency response plans for all relevant scenarios
• Conduct drills at least quarterly (evacuation, shelter-in-place, lockdown)
• Ensure visitor management systems provide real-time occupancy data for emergency roll calls
• Keep emergency exits clear, marked, and tested
• Assign and train floor wardens and emergency coordinators
• Verify that emergency communication systems reach all occupants, including visitors

7. Vendor and Contractor Risk

The risk: Third parties - contractors, maintenance workers, cleaning crews, delivery drivers - operate in the facility with varying levels of oversight, training, and background verification. They may have keys, codes, or badges that persist long after their work is complete.

Why it matters: Vendors and contractors often have access to sensitive areas (server rooms for maintenance, executive offices for cleaning) during off-hours when oversight is minimal. Workplace security risks from third parties are frequently overlooked because these individuals are “authorized” in a general sense but rarely subjected to the same scrutiny as employees.

Prevention strategies:

• Require verified check-in and check-out for all contractors, with time-stamped records
• Verify safety certifications, insurance, and background checks before granting access
• Issue temporary credentials that expire automatically at the end of the work scope
• Escort contractors in high-security areas
• Conduct regular audits of active vendor access - see our workplace security checklist for specific audit items

Risk Assessment Framework

Identifying workplace security risks is the first step. Prioritizing them is the second. Not all risks deserve equal attention - a risk that is highly likely and highly impactful demands immediate action, while a risk that is unlikely and low-impact can be monitored.

Use this likelihood-impact matrix to classify your workplace security risks:

How to use this framework:

1. List all identified workplace security risks
2. Rate each risk’s likelihood (Unlikely, Possible, Likely, Very Likely) based on historical data, industry benchmarks, and environmental factors
3. Rate each risk’s impact (Low, Medium, High, Critical) based on potential harm to people, financial loss, regulatory consequences, and operational disruption
4. Plot each risk on the matrix to determine priority
5. Address Urgent items immediately, High items within 30 days, Medium items within 90 days, and Low items in the next planning cycle

Prevention Strategies That Work Across All Risks

While each workplace security risk requires specific mitigations, several strategies address multiple risks simultaneously:

Technology Integration

Modern security platforms connect access control, visitor management, surveillance, and incident reporting into a unified system. This integration eliminates the gaps between siloed systems where workplace security risks hide. A comprehensive security management approach ensures no domain is overlooked.

Regular Audits

A structured workplace security checklist applied quarterly catches risks before they become incidents. Audits should cover all seven risk categories and produce documented findings with assigned owners and deadlines.

Employee Training

Every employee is a potential security sensor - or a potential security vulnerability. Regular training on recognizing and reporting workplace security risks transforms the entire workforce into an early-warning system. Untrained employees are the most common vector for tailgating, social engineering, and policy violations.

Digital Visitor Management

A properly implemented visitor management system addresses risks 1, 2, 5, 6, and 7 directly. Pre-registration, identity verification, host notification, badge printing, real-time occupancy tracking, and automatic record retention collectively close multiple workplace security risks with a single system. Request a demo to see this in practice.

Documented Policies

Clear, accessible, enforced policies set expectations and create accountability. Without written policies, security standards drift based on individual interpretation. Every workplace security risk should have a corresponding policy that defines acceptable behavior, prohibited actions, and consequences.

Frequently Asked Questions

What is the most common workplace security risk?

Unauthorized access - specifically tailgating - is the most commonly observed workplace security risk across industries. It occurs because it exploits human courtesy rather than technological weakness. People hold doors for others out of politeness, bypassing access controls entirely. Addressing this risk requires a combination of physical barriers (turnstiles, mantraps), technology (anti-tailgating sensors), and cultural change (training employees that verifying credentials is professional, not rude).

How often should a workplace security risk assessment be conducted?

Formal risk assessments should be conducted at least annually, with interim reviews triggered by specific events: after any security incident, when moving to a new facility, when a significant organizational change occurs (merger, acquisition, rapid headcount growth), or when regulatory requirements change. Many organizations conduct quarterly mini-assessments using a workplace security checklist and save the comprehensive assessment for an annual cycle.

Can small businesses face the same workplace security risks as large enterprises?

Yes, and in some ways small businesses are more vulnerable. They face the same risk categories but typically have fewer resources, less security expertise, and simpler controls. Small businesses are disproportionately targeted for theft and social engineering precisely because attackers assume weaker defenses. The difference is scale, not category - a small business needs the same risk framework, just implemented proportionally to its size and resources.

How does technology help mitigate workplace security risks?

Technology addresses workplace security risks through three mechanisms: prevention (access controls that stop unauthorized entry before it happens), detection (sensors, analytics, and monitoring that identify threats in real-time), and documentation (automated logging that creates complete, tamper-proof records for investigation and compliance). The most significant advancement in recent years is integration - connecting previously siloed systems so that visitor data, access logs, surveillance footage, and incident reports exist in a single, searchable platform.
