Armed and Unarmed Security

When it comes to effective security, certain environments and circumstances call for either armed or unarmed security guards. HLSA evaluates each client and job site to tailor the most effective security detail to meet your safety, security, and budget requirements. Our security guards – whether armed or unarmed – are extensively trained to provide the highest caliber of security expertise to each situation.

Whether you require armed or unarmed security for yourself or your business, your safety is our top priority. Our highly trained professional security team operates with integrity, reliability, expertise, and responsiveness, with individual training in conflict resolution and superior customer service.

Cannabis Dispensaries Security

As the cannabis industry continues to grow into a lucrative business opportunity in Chicago, it’s important to also recognize the industry’s security challenges. The large revenues involved with the marijuana industry make dispensaries frequent targets for theft and robbery. Cannabis growing facilities and dispensaries must safeguard their products, employees, facilities, and reputation amid a heavily regulated landscape. Any dispensary security plan must be prepared to protect valuable assets inside the store, on-site funds from sales, and products available for sale, as well as customers and employees.

Our team of cannabis dispensary security specialists can safeguard the most critical areas of risk exposure for your business. Our services include: 

  • Access control
  • Armed security 
  • Monitoring 
  • Escort/transport security

Construction Security

One of the most significant threats to any business owner’s bottom line is theft. It’s an unfortunate reality that thieves, which are often your own employees, will target businesses with valuable merchandise that they can resell for a profit. Due to a large volume of traffic, activity, products, machines, and regular property access by multiple people, warehouses are frequent targets for theft.

HLSA provides professional, highly trained and reliable security guards for warehouse and commercial building owners across the Chicagoland area. Our warehouse security guards serve several important functions in the protection of our clients’ inventory. Warehouses protected by security guards are far less likely to be impacted by theft, unauthorized access, vandalism and workplace violence. Some of the primary duties of our warehouse security guards include:

  • Access control
  • Enforcement of property rules and regulations
  • Employee screening
  • Actively responding to immediate threats
  • Handling security violations
  • Monitoring for potential security issues
  • Investigating and reporting security incidents


Warehouse Security

Theft and vandalism continues to be a persistent challenge for the construction industry. Construction sites are full of valuable materials such as lumber, copper, tools, and machinery. After regular business hours, these sites are deserted until the next work day, leaving the site open to potential criminal activity. 

With the cost of construction materials and tools at an all-time high, loss prevention has never been more critical for the construction industry. 

Regardless of the size or scope of your project, the potential financial risks of theft and vandalism are high. Theft causes major and often unexpected consequences for construction companies, and criminal activity can have a serious impact on your ability to complete the project on time and on budget. When materials and equipment are stolen or damaged, construction projects are delayed indefinitely and can face other unforeseen expenses. 

HLSA works closely with construction industry clients to provide comprehensive construction security services customized to each unique construction site. Our services include: 

  • Risk assessment
  • Loss prevention 
  • Mobile patrols
  • Surveillance
