You’ve likely crossed paths with a security firm's services today without realizing it.

From CCTV surveillance and cybersecurity to the guard by the ATM, or even your office keycard — good security is essential, and often invisible.

It impacts our daily lives by keeping people, businesses, property, assets, and information safe.

So, what is a security firm? And what exactly does a security firm do? Keep reading to explore the key aspects of security firms and explain their vital role in modern security.

Whether you're a security professional looking to learn more, or you’re simply curious about this industry, let’s dive into the world of security firms.

What is a security firm?

Here’s the short answer: Security firms are businesses that specialize in providing security services.

These services are designed to protect people, property, and assets from theft, vandalism, violence, and other threats.

Here's a breakdown of what a security firm can do:

  • Onsite security guard services: Security firms provide trained security guards to patrol property, deter criminal activity, and enforce access control measures. These guards can be armed or unarmed, depending on the specific needs and local regulations.
  • Security systems and monitoring: Many security firms handle the installation and monitoring of security systems. This includes alarms, video surveillance cameras, and electronic access control systems. These systems provide 24/7 footage of a property and allow for a quicker response to possible security breaches.
  • Security consulting and training: Security firms test the security of systems to identify any gaps or vulnerabilities in the current security plan.

Then they design a customized plan to address these weaknesses. 

Plus, some security firms offer training programs for staff on security procedures and emergency response protocols.

What are the types of security firms?

Security firms come in all shapes and sizes, each with a specific area of expertise. Here's a breakdown of the most common types:

  • Manned guarding services: This involves security personnel that are trained to protect or safeguard something. Here are the main types of manned security services:
  • Armed vs. unarmed: Armed guards carry firearms for high-risk situations (banks, jewelry stores). Unarmed guards provide a visible security presence (office buildings, apartment complexes).
  • Static vs. mobile: Static guards stay at a designated post (entrance gate). Mobile guards patrol larger areas on foot or in vehicles (construction sites, large properties).
  • Executive protection (Bodyguards): Specialists who protect high-profile individuals (CEOs, celebrities).
  • Event security: Professionals who manage crowd control and VIP safety (concerts, conferences).
  • Electronic security services: These firms install and monitor electronic security systems like alarms, cameras, and access control. They design systems based on what needs security, and can offer emergency response when alarms are triggered (warehouses, retail stores).
  • Security consulting firms: These firms assess security risks, develop security plans, and train staff. They identify weak spots, create strategies, and ensure the team is prepared for emergencies through training (businesses of all sizes).
  • Private investigation: These firms conduct investigations for various purposes (insurance claims, employee theft, personal matters). They use surveillance and analysis to gain information (legal cases, missing persons).

What types of services can security firms perform?

Security firms are your partners in keeping things safe and secure. They offer a range of services designed to fit specific needs. Here's a breakdown of what they can do for you:

Access control and screening

Security firms establish access control systems at entry points of buildings, campuses, or events. They provide security personnel to verify IDs, issue visitor passes, conduct bag searches, and use metal detectors to prevent unauthorized access.

Example: Security guards are tasked with checking IDs at building entrances to prevent unauthorized access. You'll find them in office buildings, apartment complexes, and other secure locations.

Armed security services

For high-risk environments like banks, government buildings, and high-value properties, armed guards offer an elevated level of security. These guards are licensed to carry firearms and trained to respond to situations that pose immediate threats.

Examples: Banks, museums, government buildings, and some schools have armed security staff readily available to monitor and respond to security concerns.

Surveillance and monitoring

Firms also take on the task of setting up surveillance systems, including CCTV cameras and motion detectors. They monitor these feeds in real-time to detect suspicious activities. They also conduct virtual patrols where live footage is analyzed by security experts who alert local guards or authorities when necessary.

Examples: Security cameras and motion detectors help deter crime and make it easier to monitor suspicious activity. Warehouses, retail stores, and parking lots often use these systems.

Loss prevention

Retailers often employ security firms to conduct loss prevention activities like detecting shoplifting or internal theft. Security professionals monitor store floors, provide training to store employees, and assist with investigations of theft incidents.

Examples: Security personnel in retail stores are trained to spot shoplifters and prevent internal theft. Warehouses and distribution centers also have staff who monitor high-risk areas and investigate suspicious activity.

Escort and transportation services

There are security firms that provide personnel to accompany high-profile individuals during travel or public appearances, ensuring their safety.

Examples: Bodyguards are often employed to accompany executives or celebrities during travel or public appearances. For valuables like cash or documents, armored vehicles and secure transport protocols are available.

Emergency response and crisis management

Security firms don't just react — they plan ahead for emergencies. In situations like natural disasters, violent incidents, or accidents, security firms can quickly deploy emergency response teams to give medical aid, evacuate affected individuals, or secure vulnerable facilities.

They also offer crisis management training to staff, helping them remain calm and effective during emergencies.

Examples: They develop a protocol to follow in case of a fire or an earthquake. The goal is to minimize risk and keep personnel and assets safe even amidst crisis situations.

Why do companies hire a security firm?

Running a business comes with a lot of responsibility, and keeping people, property, data, and assets safe is a top priority.

That's where security firms come in. Here are some of the key reasons companies choose to hire them:

  • Reduced risk and liability: Preventing security incidents is far less costly than managing the aftermath. A strong security plan can help mitigate potential risks and losses. Security firms can identify security vulnerabilities and recommend solutions to minimize liability in case of incidents.
  • Peace of mind and focus: By outsourcing security concerns to a qualified firm, companies can free up time and resources to focus on core business operations. Security firms handle the day-to-day tasks and offer 24/7 oversight, giving you peace of mind.
  • Expertise and resources: Security firms have the know-how and the resources to develop and execute security plans. They use their knowledge of security best practices and the latest technology to keep businesses safe.
  • Access to technology: Security firms often have access to cutting-edge technology, such as advanced surveillance systems, facial recognition software, and data analytics. This tech-driven approach enhances their ability to monitor, detect, and respond to potential threats effectively.
  • Specialized services: Many firms provide specialized services like executive protection, event security, or cybersecurity solutions, catering to specific needs and industries.
  • Rapid response to emergencies: During emergencies like natural disasters or active shooter situations, security firms can quickly deploy teams to contain the situation, coordinate with authorities, and safeguard lives and assets. This swift action helps bring things back to normal as quickly as possible.
  • Cost-effectiveness: Hiring and managing an in-house security team can be expensive and time consuming. Security firms offer flexible solutions, allowing businesses to pay only for the services they need, whether it's short-term event security or ongoing property surveillance.

Who can own or manage a security firm?

Security firms play an important role in keeping communities and businesses safe. But who exactly gets to be the brains behind the operation?

Here's a breakdown of what it takes to own or manage a security firm:

  • Know business management: First, you'll need a solid grasp of business management principles. This includes understanding how to run a company, manage finances, attract clients, and figure out legal requirements.
  • Know YOUR business: Those with a background in law enforcement, military service, or private security often have the skills and knowledge needed to operate a security firm. Their firsthand experience in managing threats and understanding security protocols gives them an edge in this field.
  • Study licensing requirements: Security firms operate under specific licensing regulations that change based on which state you’re in. You'll need to research and get the appropriate licenses to operate legally. Some states may require the owner or a designated manager to hold a specific security license.
  • Ensure you have a clean criminal background: Security firms are entrusted with protecting people and property, so a clean criminal background check is typically mandatory for ownership or management positions.

Remember: These are general guidelines. Specific requirements for ownership and management may vary depending on the location and the size and type of security firm you want to establish. It's always best to check with your state's licensing authority for the most up-to-date information.

What to look for in a security firm

Choosing the right security firm is a critical decision. You're entrusting them with safeguarding your most valuable assets, whether it's physical security, personal information, or even lives. If you’re looking to hire a security firm, here’s a checklist of things to ask about:

Find out about their experience and qualifications:

  • Look for a firm with a proven track record and experience in the specific industry.
  • How long has the firm been in business?
  • Are they licensed and insured in your state? Verify their license status online.
  • What certifications do their security guards hold? Look for guards with relevant training (e.g., first aid, CPR).

Find out what services they offer:

  • Identify your specific security needs (e.g., access control, mobile patrol, alarm monitoring).
  • Does the firm offer the services you require?
  • Can they customize a security plan to fit your specific needs and budget?

Find out about their operations:

  • How do they handle emergencies?
  • What is their response time for alarms or security incidents?
  • Do they have a 24/7 operations center to monitor your security system?

Find out about their costs:

  • Get quotes from several security firms before making a decision.
  • Carefully review the contract terms, including service details, pricing structure, and termination clauses.
  • What is included in the pricing (e.g., guard hourly rates, equipment costs, monitoring fees)?

BONUS — Here are some things that only a security expert would tell you to keep in mind when choosing a security firm:

  • While many firms highlight their role in preventing crime, a security expert would emphasize how a strong security plan can actually reduce your insurance premiums. By demonstrating a proactive approach to security, you can become a lower-risk client for insurance companies.
  • Modern security systems offer a powerful advantage — integration. Look for a firm that can seamlessly integrate electronic security systems (cameras, alarms) with on-site security personnel.

This creates a layered security approach where electronic alerts trigger a rapid human response, maximizing effectiveness.
