Siemens has been in building technology longer than most access control companies have existed, and it still sells the way it always has, through the partner who also handles your fire panel and your HVAC. Kisi sells access control on its own, directly to you, with pricing published before you speak to anybody. That is not a small distinction and it decides most of what follows. Here is what each one can offer.
At a glance #
Siemens, access control as one system inside a building #
Siemens sells access control as part of its building technology portfolio, next to fire, intrusion, video and building management. The flagship platform, SiPass integrated, runs on an on-premises server, works with readers from most manufacturers and handles credentials from smart cards through to biometrics. A cloud layer sits on top of it for central identity management and phone-based entry.
It scales to sites with tens of thousands of doors and it is built to be run by people whose job is security. That is the part worth weighing. Siemens suits buildings where access control is one input into a wider security operation, rather than buildings where somebody in operations needs to add a user between meetings.
Kisi, access control as its own platform #
There is no server. The Controller Pro 2 sits at the door and everything else runs in the cloud, which means the administrative dashboard opens in a browser and firmware updates arrive on their own.
The controller is built to take over existing Wiegand wiring and readers, so most retrofits skip the part where somebody pulls new cable through a finished building. Cards and fobs still work. On top of that you get Apple Wallet and Apple Watch badges, so people tap in without waking their phone, and MotionSense for hands-free unlocking.
Video is not Kisi hardware. Tailgating detection and surveillance come through camera partners, which means you pick your own cameras rather than inheriting a vendor's.
The integration library is the clearest signal of who Kisi is built for. Siemens connects deepest to other Siemens building systems. Kisi connects to the software your team already opens every morning: identity providers, HR systems, gym management platforms, coworking tools, with an open API for whatever is not on the list.
How you buy it, and who touches it afterwards #
Siemens goes through its partner network. An integrator scopes the site, specifies the hardware and quotes the job, then handles the installation and usually the changes after it. For a large facility that is a sensible way to buy, because an engineer is designing the system and stands behind it.
Kisi sells directly. You can read what it costs before talking to anyone, and deployment can go to your own facilities technician, a local electrician working from published wiring documentation, or a certified installer from Kisi's network if you would rather hand it over.
The difference shows up most on the small stuff. Under an integrator model, changing a door schedule is a ticket and a callout. Under a direct model it is a setting you change yourself in about a minute.
What it costs #
Siemens doesn't publishes pricing. What you pay depends on the site, the integrator, the licensing your configuration needs, the installation labour and the maintenance contract attached to it. That is normal enterprise procurement, but it is slow, and you cannot compare it against anything until the quote arrives. If you are still working out the shape of the budget, our breakdown of access control installation costs covers what the hardware and labour typically run regardless of vendor.
Kisi starts at $99 a month for software, with hardware quoted separately, and plans scale on the metric that matches how the space works. Membership businesses scale on active users rather than door count, so putting readers on interior doors does not raise the bill.
Which industries are targeted #
Siemens is the stronger choice when physical security is a department with its own staff and its own regulator. Pharmaceutical and life sciences facilities, data centres, hospital networks, university campuses and industrial sites all sit squarely there, particularly where access has to coordinate with fire, intrusion and building management, and where audit requirements are written into the operating licence.
Kisi fits buildings where access control is an operations problem instead. Offices that want door permissions to follow the identity provider without anyone touching a spreadsheet. Gyms and studios where the door needs to know whether a membership lapsed last night. Coworking operators running members across floors and locations. Multi-tenant commercial buildings connecting access to the tenant tools they already pay for.

Siemens reviews #
Siemens access control has effectively no presence on G2 or Capterra. If you are evaluating SiPass seriously, plan on reference calls arranged through your integrator and ask for sites the same size as yours.
Which one is right for you? #
Choose Kisi if:
- You want to see pricing and try the platform before entering a sales process
- Access control has to connect to software you already run, whether that is Okta, a gym management system or a coworking platform
- You would rather change a door schedule yourself than raise a ticket
- You are retrofitting and want to keep the wiring, readers and cards already in the building
- Apple Wallet credentials or hands-free unlocking matter to how people move through the space
Choose Siemens if:
- You already run SiPass or SIPORT and want to modernize the management layer rather than replace the system
- Access control sits inside a wider Siemens deployment covering fire, HVAC or building management
- Your site is a regulated industrial, pharmaceutical, healthcare or campus environment with a dedicated security team
- Entry data needs to feed time and attendance
- You prefer to buy complex systems through an engineering partner who scopes, installs and supports the whole thing
Looking for a Siemens alternative? #
If you want access control you can price, deploy and manage without a building technology contract sitting behind it, get a Kisi quote and see how it fits the space you already have.
