The second is Pure Access Manager, on-premises software that lets you manage your access control system from any device in your network.

Although you need to contact ISONAS directly to get an accurate quote for its hardware and software, we were able to get some pricing information from third-party sites. Our research shows that a Reader-Controller is $817. A one-year, one-to-five-door license for Pure Access Cloud costs $412, while a 251+ door license is priced at $4,120. ISONAS also offers web-based training to help you with setup.

Best for Large Teams : Honeywell



A global provider of security products, Honeywell offers fully integrated and scalable access control systems for unlimited users and guests, making it our choice as the best for large teams.

  • Simple installation

  • Easily scalable

  • Supports unlimited cardholders

  • Uses third-party contractors and installers

  • No mobile phone access options

Honeywell’s first product was a thermostat when it started business in 1906. Today, the multi-billion-dollar corporation is an international provider of aerospace, building, and performance safety solutions. Its single interface integrates access control, video surveillance, and intrusion protection with unlimited user access, making it our top choice for large teams.  

Honeywell’s premier access control system is its WIN-PAK integrated security software. This robust platform combines access control, video surveillance, and intrusion detection through a browser-based interface. WIN-PAK can be scaled from a single site business to multi-regional enterprises with no limits on the number of users. The software also supports third-party integrations, including biometric readers, point-of-sale (POS) systems, visitor management, and HR applications.  

Honeywell also offers a variety of control panels, keypads, expansion modules, and sensors for just about any security need. While its door controllers are compatible with major security products in the marketplace, this versatility can decrease the security of Honeywell’s systems.  

As you would expect, Honeywell offers security readers that can be accessed with ID cards, key fobs, biometric recognition, and smartphones. Its system also integrates with alarms, fire safety, video surveillance systems, and more.

Honeywell does not sell or support its products directly, relying instead on third-party vendors, contractors, and installers. As a result, you will need to contact a Honeywell sales team to get a quote for products, software, installation, and maintenance.

Best Identity Authentication Access Control : HID Global

HID Global

HID Global

HID Global provides physical and digital security access solutions to governments, universities, hospitals, financial institutions, and companies in over 100 countries. We chose it as the best for identity authentication access control due to its sophisticated multi-factor authentication.

  • Biometric security options

  • Multi-factor authentication

  • Custom ID cards and badges

  • No cloud-based option

  • Requires a local server

HID Global began in 1991 as a division of the Hughes Aircraft Company tasked with creating technology that could identify radio frequencies. It soon moved into developing access control and proximity card readers and currently provides access control systems around the world. It takes our top spot as the best for identity authentication access control due to its multi-factor biometric authentication technology.

Although HID offers standard security badges similar to other providers, it takes security one step further by using the same level of encryption as electronic passports and major credit cards. HID also offers sophisticated access via smartphones and watches as well as applications targeted to specific industries, including education and hospitality.

Most impressive of all is HID’s biometric security features that combine unique physical ID data with a secure card for the ultimate in multi-factor authentication. Without getting too technical, it uses multispectral fingerprint imaging to capture fingerprints on both surface and subsurface levels using multiple wavelengths, angles, and orientations, and can even verify that a fingerprint scan is from living tissue.   

One downside is that HID does not offer cloud-based software, requiring a system to be locally hosted on a local server which you must provide. Pricing is also not available without requesting a detailed consultation with a sales rep.

Frequently Asked Questions (FAQs) 

What Is an Access Control System and How Does It Work?

At its most basic, an access control system secures doors with electronic locks that can be opened with special access codes or devices like key cards, key fobs, or even a smartphone.

Each system uses electronic door locks which can only be accessed with a key card reader or keypad. These readers are then connected to a central control hub which in turn is linked to access software that can be used to monitor and control the whole system. Access control systems are typically either hardwired into a dedicated network or connected to an existing network.        

What Are the Three Types of Access Control Systems?

Access control systems can be broken down into discretionary, mandatory, and role-based access control.

The least restrictive, discretionary access control (DAC), allows administrators to customize access based on need. It typically grants access permissions based on set lists and directories with administrators being able to pass access controls to other users. 

On the other end of the spectrum is the mandatory access control (MAC) system. This restricts the ability of administrators to grant access permissions based on parameters defined by the software or its owner. In this model, users are granted access based on their specific classification level and will have to create a new profile if their access needs change.

Perhaps the most widely used control system, role-based access control (RBAC), grants pre-defined access permissions based on a user’s position or role in an organization. While this is the easiest type of access to set up, it’s also the least flexible as administrators typically can’t grant users access beyond their role.       

What Does Access Control Cost?

Because of the differing needs of each business as well as the variety of available devices, the price of an access control system can vary widely.

In our research, the lowest price for the software for a small system that controls five or fewer doors came in at just over $400 per year, while enterprise solutions can range into an annual cost of thousands of dollars. The cost of door readers can range from $600 to $800 per device.

Other costs to consider are consultation, installation, software and hardware upgrades, and maintenance, which can vary by provider.    

Can Access Control Systems Save Your Business Money?

Businesses that have sensitive or secure areas with restricted access can save money on more elaborate security protocols with a simple access control system. Think manufacturers that need to secure areas with dangerous machinery that only qualified specialists can use or medical facilities that need to protect patient records.    

Similarly, investing in an access control system can potentially save businesses money in litigation or fines that other businesses might suffer by exposing sensitive customer records to unauthorized employees or from visitors being injured by wandering into dangerous areas.     

How We Chose the Best Access Control Systems 

We looked at over a dozen access control system providers for this review. We started with companies that had a long history or deep expertise in electronic security. Next, we focused on providers with systems that were easy to set up and use, thus providing flexibility and accessibility to a wide range of users.

While pricing was a consideration, we also looked at providers that offered specific solutions or support for specific industries or scales of business. As a result, some of these providers might be more expensive but offer the best solution for the job.
