How Cloud Technology Is Changing the Way Businesses Control Building Access

For decades, controlling building access meant issuing keycards, maintaining local servers, and asking someone on-site to change permissions whenever an employee joined, left, or changed roles. That model is quickly giving way to cloud-managed access.

The numbers show how quickly expectations are changing. A 2025 industry survey found that 17% of organizations were already operating fully mobile credential environments, more than three times the share reported in 2023. Another 2025 physical security survey found that 37% of IT professionals prioritized cloud-based security solutions, compared with 27% of physical security professionals. 

Consider a company with offices in New York, Chicago, and Austin. With a traditional setup, removing a departing employee’s access or changing permissions across sites may involve separate systems and local administrators. A cloud platform can bring those controls into one place.

That change is making building access faster to manage, easier to scale, and more useful as a source of security information. Below, we look at how cloud technology is changing access control in practice and what businesses should consider before upgrading.

1. Access Management Is Moving From the Server Room to a Central Dashboard

One of the biggest changes cloud technology brings is centralized administration.

In a traditional on-premises environment, access control software may be installed on a local server at each building. This can work well for a single location, but complexity increases when a company adds offices, warehouses, clinics, or other facilities.

Cloud management allows authorized administrators to manage users, credentials, schedules, and access rules remotely. Instead of maintaining separate policies for every location, a company can establish consistent rules across its portfolio.

That is particularly useful for common business events. When an employee changes departments, for example, administrators can modify the areas that person can access. If a contractor needs access to one building for a week, permissions can be limited by location and schedule. When an employee leaves, credentials can be revoked without collecting every physical key.

The interest in this model is measurable. In a 2025 controller industry survey, 50% of respondents identified cloud connectivity as one of the most important trends influencing controller purchasing decisions. Respondents pointed to centralized management, scalability, real-time monitoring, and simpler updates as important advantages.

For growing businesses, this is less about putting a door “in the cloud” and more about making the administrative layer accessible wherever the security team needs it.

2. Businesses Can Choose Credentials Based on the Risk of Each Door

Moving to cloud management does not mean every company needs to use the same credential at every entrance.

There are several types of door access control systems, ranging from familiar cards and key fobs to PINs, mobile credentials, and biometric authentication. The appropriate choice depends on how a space is used and the consequences of unauthorized entry.

For example, an office lobby might use a mobile credential for convenient employee access, while a server room or sensitive records area could require stronger authentication. Coram provides a useful example of how these components fit together. Its access-control guidance explains that credentials are linked to individual users, while readers pass credential information to a controller that evaluates permissions and schedules. The system can support cards, key fobs, PINs, mobile credentials, and biometric identifiers, with multi-factor authentication available when stronger verification is appropriate.

The broader market is moving in the same direction. Research published in 2025 found that 61% of security leaders considered mobile credentials a leading access-control trend, while biometric use for physical access control was expected to increase from 35% to 48% based on organizations’ stated plans.

This gives businesses an important advantage: authentication can match the risk rather than forcing every door into an identical security model.

3. Access Events Become Useful Security Information

A locked door answers one question: can this person enter?

A modern access control system can answer several more. Who attempted entry? Which credential was presented? Was access approved? What time did it happen? Was the door subsequently forced or left open?

Cloud-connected software makes this information easier to centralize and review.

A properly configured access control chain typically involves five elements: the user’s credential, the reader, a controller, electronic door hardware and sensors, and management software. Coram’s technical explanation notes that this entire access decision can happen in under one second, with the software logging successful and unsuccessful attempts.

Sensors add important context. A door-position indicator can show whether a door remained open, while request-to-exit hardware helps distinguish a normal exit from suspicious door activity.

That context matters in a real investigation. Suppose a business discovers expensive equipment missing from a restricted storage area. Instead of simply knowing that the door was unlocked at 8:42 p.m., security personnel may be able to review the credential involved, access rules, relevant door events, and connected video.

Cloud technology turns individual door events into searchable operational records rather than isolated electronic actions.

4. Mobile Credentials Are Reducing Dependence on Physical Badges

Physical badges remain common, but smartphones are increasingly becoming credentials themselves.

The appeal is practical. Businesses routinely issue, replace, collect, and deactivate physical cards. Employees can forget a badge at home, while lost cards create both administrative work and security concerns.

Mobile credentials allow approved users to authenticate with devices they already carry. The 2025 Wireless Access Control Report found that fully mobile credential deployments represented 17% of respondents, more than triple the level recorded in 2023, while another 26% were planning future mobile deployments.

This can make onboarding and offboarding more efficient. A new employee can receive an appropriate digital credential, while a departing employee’s authorization can be removed centrally.

Mobile access also fits hybrid workplaces. Someone who visits headquarters twice per month does not necessarily need the same physical badge-management process as a person working there every day.

Physical credentials are not disappearing, and some environments will continue to prefer them. The important change is that businesses now have more flexibility in deciding how identity is presented at each door.

5. Multi-Site Expansion No Longer Has to Mean Multiple Security Silos

Access control becomes substantially more difficult when a business expands.

Imagine a company growing from three offices to 30. If every building has separate administration, every new site creates another place to configure users, maintain software, review logs, and troubleshoot problems.

Cloud architecture can reduce that fragmentation.

A centralized platform can allow security teams to:

• Apply access policies across multiple locations
• Add or remove users remotely
• Review activity without visiting individual sites
• Adjust schedules when business hours change
• Add new locations without creating entirely separate management workflows

This does not eliminate the physical infrastructure at each building. Readers, controllers, locks, sensors, and safe emergency egress still need to function correctly.

In fact, modern systems can often continue basic door operation when internet connectivity is interrupted because controllers store access rules locally. Cloud connectivity is primarily responsible for functions such as centralized reporting, remote management, software updates, and dashboard visibility.

That distinction is important for businesses concerned that moving management to the cloud means a lost internet connection automatically locks everyone out.

6. Access Control Is Becoming Part of a Larger Security Ecosystem

Perhaps the biggest long-term change is that access control is becoming less isolated.

Cloud software can connect door events with video surveillance, alarms, visitor management, and other security tools. This helps teams understand the context surrounding an access event rather than evaluating a badge transaction on its own.

Suppose an employee credential is denied repeatedly at a warehouse after midnight. The event itself could be innocent, perhaps the employee is using an expired credential. But if the access platform can connect the event to a nearby camera, security personnel can verify the situation much faster.

This type of integration is one reason businesses should evaluate software architecture rather than focusing only on readers and locks.

Before choosing a system, organizations should consider whether it supports remote management, additional doors and locations, integrations with other security platforms, local operation during network outages, and appropriate reporting. They should also calculate total ownership costs, including installation, cabling, software subscriptions, maintenance, and credential replacement.

The cheapest hardware at installation can become expensive if every future change requires specialized on-site work.

7. Cloud Access Requires Stronger Attention to Cybersecurity

Cloud connectivity creates convenience, but it also means physical security teams need to think more like IT teams.

Credentials, permissions, administrator accounts, access logs, and integrations are valuable security data. Weak administrator passwords or poorly controlled accounts can undermine sophisticated door hardware.

Businesses should therefore treat cloud access control as both a physical and digital security system. Important practices include strong administrator authentication, role-based privileges, prompt account removal, secure integrations, software updates, and regular review of access logs.

The convergence of physical security and IT is already visible. One 2025 survey found that 47% of IT professionals prioritized deploying cybersecurity tools, compared with 27% of physical security professionals. The same research found stronger interest in cloud-based solutions among IT respondents.

For business leaders, this means access-control purchasing should no longer sit exclusively with facilities management. Security, facilities, IT, and compliance teams all have a role in evaluating how the system is deployed and maintained.

Key Takeaways

• Cloud technology centralizes access management, allowing businesses to administer doors, users, schedules, and permissions across multiple locations.
• Mobile access is becoming mainstream, with fully mobile credential environments more than tripling between the 2023 and 2025 editions of one major industry survey. 
• Different doors can use different authentication methods, including cards, PINs, smartphones, biometrics, or multi-factor authentication.
• Modern access control provides context, recording successful and denied access attempts while door sensors can identify forced or propped-open doors.
• Cloud management does not necessarily mean doors stop working when the internet fails, because properly designed controllers can retain rules locally. 
• Cybersecurity is now part of physical access control, making collaboration between security, facilities, and IT increasingly important.

FAQs

What is cloud-based building access control?

It is an access-control architecture in which administrators use cloud-hosted software to manage credentials, users, doors, schedules, logs, and other settings. Physical readers, controllers, locks, and sensors remain at the building.

What types of credentials can modern access control systems use?

Common options include cards, key fobs, PIN codes, smartphone credentials, fingerprints, and other biometric identifiers. Higher-risk areas may use more than one authentication factor.

Will doors stop working if the internet goes down?

Not necessarily. Many systems store permissions and access rules locally on controllers so basic door operation can continue during an internet outage. The exact behavior depends on system design and configuration.

Is cloud access control useful for small businesses?

Yes. Centralized administration can benefit a single office, but its advantages become especially noticeable as a company adds employees, doors, or locations.

Conclusion

Cloud technology is changing access control because businesses now expect more from a door than a simple lock-and-unlock decision.

They want to manage permissions remotely, issue modern credentials, understand denied access attempts, connect doors with other security systems, and expand without building another isolated security environment at every new location.

The technology still depends on fundamentals such as properly installed readers, controllers, locks, sensors, and safe emergency egress. What the cloud changes is how those components are managed and how useful their information becomes.

For growing businesses, that shift can mean faster administration, stronger visibility, easier scaling, and more consistent security across every building they operate.
