Advantages of cloud-based security for access control
Published on 21st November 2025
If you told someone ten years ago that they wouldn’t need a physical key to start their car or open their front door, they probably wouldn’t have believed you. Yet here we are, moving rapidly towards the reality where metal keys are going to one day become obsolete.
We have all had to juggle keycards and fobs in the past, dealing with the hassle of forgetting them at home, losing them in the canteen, or accidentally wiping them with a stray magnet. Cloud-based access removes that clutter and replaces it with something that actually works for the people using the building.
Here is our take on why moving your access control to the cloud is the logical next step for modern buildings.
Management that adapts to you
The biggest advantage of a cloud-based system is that access can be controlled by administrators from absolutely anywhere. We don’t believe you should have to be physically standing in front of a door to decide who gets to walk through it. This means updating permissions becomes a simple digital task you can handle from your laptop, rather than a logistical headache that requires a site visit.
Stopping the hardware money drain
When you choose wallet passes as an access credential, you immediately stop the cycle of buying and replacing plastic cards and keyfobs. Since there are no keys to get cut or cards to re-issue when they inevitably get lost, your overall running costs reduce - and it’s not just the card or keyfob - it’s the whole process around replacing it and the time it takes. It shifts access permissions into a purely software activity, which is where the real cost savings happen.
Real authentication with wallet passes
It has always been far too easy to hand a keycard to a friend so they can sneak into the gym or the office, but people are much less likely to hand over their unlocked phone. When you use a phone based wallet pass, it’s much harder for someone to imitate the user or share their access with someone else. Plus, when your digital management is cloud-based, authorised staff can see exactly who is in the building in real-time, which is vital for keeping track of occupancy.
Tighter security and better monitoring
It becomes incredibly easy to issue and revoke access remotely when your controls are in the cloud. This is a vast improvement over the old method of having to be on the premises to reprogram a physical card, or worse, having to call a locksmith to change the barrels because a master key has gone missing. If someone leaves the company or a tenancy ends, we can simply revoke their access instantly - and if you use your directory or membership system as the authoritative data source, this process of issuance (for both activation and revocation) can be automatic.
Systems that actually talk to each other
Modern wireless door locks are designed to fit in with the other tools you use to run your building. This creates a much better experience for members and visitors, who can simply use their credential to enter the building and then use that same digital identity to use the printer or book a meeting room. It removes the need to fumble with keys or memorise four-digit codes, allowing people to just get on with their day.
Cloud-based security represents a significant step forward in how we move through spaces. By removing the limitations of physical keys and cards, we can all enjoy greater flexibility, better security, and sensible cost savings.
We believe that cloud-based access isn't just a nice-to-have feature anymore. Being able to manage access remotely, see who is coming and going, and link it up with your other building systems makes it essential for any business that cares about creating a frustration-free environment.
