Update: We revised this page to include a new partnership announced by our best pick for businesses with multiple locations, Johnson Controls.

Keeping your employees and facility secure is a top priority for any business owner. A facility access control system is one of the most efficient ways to not only prevent unauthorized visitors from entering your business, but also to manage employee access.  

Honestly, it's not practical to give each employee their own set of keys. An access control system is a better option, as it lets employees enter locked facilities with specialized credentials – such as a key card, PIN, key fob or mobile phone app – that they input into a reader to unlock the door. 

Best Picks


Editor's note: Looking for an access control system for your business? Complete the questionnaire below to have our vendor partners connect you with free information.

Access control systems also let employers restrict the locations each employee can enter, setting levels of security to balance their workers' safety and convenience. When an employee leaves the company, their credentials can simply be deactivated to prevent them from gaining unauthorized access.   

With access control security, you know who enters your business, when they enter and what door they use. These systems also include analytics that allow you to track where your employees are. In addition, they allow you to section off rooms or areas to authorized employees and receive reports of suspicious activity, such as if someone tries to enter an area where they don't belong.  

This guide provides reviews of some of the top systems on the market, as well as details on the features these systems include and what you can expect to pay for an access control system. 


Pricing for access control systems vary greatly depending on the specific hardware you want, the number of access points you have, and whether you choose a traditional or IP system. Pricing also changes if you have the system professionally installed rather than doing it yourself. You will likely need to speak with a company representative about your specific needs before you can receive an accurate estimate of what your access control system will cost. Most companies will provide you with a free quote.

What to Expect in 2020

The use of access control systems is predicted to grow in the years to come. Data from the research firm IHS Markit projects the access control market to grow by 6% by 2021.  

The market analysis found that growth is being driven by increased options for small and midsize businesses, as well as enterprise organizations, including more wireless and cloud-hosted solutions.  

Moving into 2020, we expect an increased adoption of biometric tools that have been introduced in recent years. With biometrics, employees only need a fingerprint or facial scan to access their building or office. Biometrics is already widely used in extremely secure facilities, and it is becoming more popular in other B2B services, like time and attendance systems. Thus, we expect a growing number of businesses will adopt this technology for their access control needs as well.   

Control systems that use mobile apps have also become popular, freeing employees from carrying a specific access card. They simply open the mobile app and scan a barcode to enter the workplace.   

Fingerprints, facial recognition scans, and smartphone apps increase security and ease of use for employees, and they can save businesses money in the long run. All of these options do away with the traditional access card, and not having to continue purchasing these cards could positively affect the bottom line of some organizations.


An access control system does just what it sounds like: It controls entry or access to your business or facility by securing your building or sensitive areas with specialized credentials, advanced readers, alarm systems. Most systems also include reporting software.

What Features Do You Need?

We looked at each access control company for the features we believe are most important to your business's security. We examined the technical aspects of the products and checked to see if companies offered certain services. We gathered this data by browsing these companies' websites and contacting them anonymously to gather information and gauge the level of customer service we received. 

Security: Keep Your Employees and Your Business Safe

Security should be the most important factor when choosing an access control system. Services that offer outdated technology, cut corners or are missing key safety features, such as lockdown modes and alarms, did not score well in our evaluation.

Door readers and physical credentials come in many varieties, but the best services include readers with their own memory and processors, as well as credentials that incorporate some form of encryption. Proprietary technology, rather than open source, is more secure and less likely to be taken advantage of.

The door access readers themselves should be physically secured with specialty screws, and the wiring tucked away and protected. Some readers even have tamper alarms that go off if they are physically altered or removed. Door hold alarms can alert you when select doors are held open too long. Options for different types of credentials, as well as allowing for multiple credential authentication, are a must.

Not all systems offer emergency alarms, so you must decide if these are necessary for your business. Crucial safety protocols include fire and carbon monoxide alerts, along with break-in alarms. In case of emergencies, you should be able to customize lockdown scenarios, programming the system to automatically open and lock selected doors on such occasions.

Protection 1 does well in easily integrating these added security features with its access control systems. While some companies on our list don't offer these security features, they are increasingly standard for access control providers.   

Reporting and Administrating: Manage Your System the Way You Want

A detailed reporting interface allows you to observe the movements of your employees throughout the building, keeping tabs on who enters when and at which door. The best access control software integrates with surveillance cameras, recording anytime an employee uses a credential to open a door. These records are useful when investigating suspicious activity, allowing you to verify if it was indeed an employee who used the credentials. The best systems can store these records indefinitely, so you can go back to any date and examine the history. This is extremely useful if you must perform an audit on security or are investigating an event that happened at your business.

If you're away from your business a lot, opt for a service that allows you to manage your access control from mobile devices. If your company regularly receives visitors, your system should have options for allowing temporary access to such guests.

Consider also whether you want your access control system to tie into your time and attendance system, which some services do. If you're concerned about spending too much time monitoring your access control system, some companies offer to manage the monitoring and security for you so you can focus on running your business.


Nearly all the companies we evaluated provide professional installation, either by their own professionals or through third-party installers or dealers. The number of doors that an access control system can cover varies by company. Some companies cover as many doors as you need but are limited by how many door readers each control panel supports. You may need to install multiple control panels if you need to cover more than just a few doors, and that can be costly and take up space. Other services have the capacity to host unlimited doors.

In most cases, systems can accommodate an unlimited number of employees. It's also rare that a company does not push free firmware updates to the system once they are released.

Help and Support

We tested customer support thoroughly, looking to see if customer service representatives for the companies were knowledgeable, transparent and accommodating. We also took into account the timeliness of each company's response, as well as whether it has 24/7 support available or offers live chat on their website. A company that conducts training for employees on how to use the system is a must. Typically, access control companies are also security companies and offer a bevy of resources on their websites on how to improve your security.

State of the Industry

Access Control: Traditional vs. IP Systems

There are two main types of access control systems. The first is the traditional method where control panels act as hubs for door readers, door locks, cameras and the system's interface, usually a PC. The door readers and control panels connect with proprietary power and communication wiring. The second, newer type of access control is called an IP system, or a cloud-based system, in which the door readers connect directly to a network, usually through Ethernet or wireless signals. Instead of control panels, these systems are usually run with a less bulky and easier-to-install network hub.

IP systems are newer and have been gaining popularity as cloud storage becomes more commonplace in both business and personal realms. Many businesses choose IP systems for their ease of use, accessibility and reliability, though there is still contention in the security market over which method is better.

IP systems are much simpler to set up, usually just needing Ethernet connections to your company's network rather than serial connections to multiple control panels. There is no limit to how many door readers can be connected to an IP system, while in a traditional system, control panels can only be connected to a handful of doors, so you'd need several panels to secure a building with many access points.

Critics say IP systems are less secure than traditional proprietary access control setups because network outages can affect performance and they are more susceptible to hackers. Ultimately, the system that would best suit your company depends on your needs. Some access control services offer both options and will work with you to determine which type would work best.

Working With Credentials

There are four main forms of authentication: a physical credential like a card or key fob, a password or PIN, a mobile app, and something biometric like your fingerprint. Biometric credentials are becoming more popular. Many of the companies we reviewed offer biometric devices.

For optimal security, use at least two of these methods for authentication. This practice is known as layered security, which requires employees to go through multiple safeguards before entering your business.

If an employee leaves the company, whether they resign or are terminated, their credentials should be voided immediately. Most control systems have an option to instantly revoke an employee's access, and some can even automatically suspend credentials if the system detects suspicious behavior.

Additional Tips

Enhancing Your Security

Security professionals recommend that businesses do a yearly review of their security and access control. Consider your security needs and how your current system has served you. If there have been any security incidents over the past year, reflect on whether your current system is at fault and if it could be more secure.

As part of your company's routine security inspections, regularly examine the hardware involved with the access control system and check door readers, along with the wiring that connects them to the system, for signs of tampering. If the system is connected to a control panel, be sure it is installed in a secure location that remains locked at all times.

You can enhance your security by setting up what is called an anti-passback system. This means setting up a reader on both sides of a door, requiring employees to use their credentials to exit the building as well as to enter. An anti-passback system will prevent credentials from being used to enter a door twice because it detects that the user is already in the building and knows they haven't left until they've used the exit reader. This can protect against cases of copied cards, cards being passed to others after opening the door or passcodes falling into the wrong hands.

You can't improve security if you can't measure its effectiveness. - Amrit Williams (security expert and blogger) If it works and protects, then it is functioning well. The moment it fails is the moment it needs to be improved and upgraded. Until then, you can't measure it with a yardstick. The value of security, it sounds a bit vague at the moment.
