Secure Wi-Fi Authentication with Device Certificates
Protect your WiFi network from unauthorized use, data interception, and more with easy-to-implement WiFi certificates starting at just $16/yr.
WiFi Authentication Certificates
The Internet exposes us to a multitude of threats like Man-In-The-Middle attacks and session hijacking. To counter these risks and secure online communications, we rely on SSL/TLS certificates. But what about the threats that involve public or enterprise WiFi networks?
A WiFi certificate secures access to public networks – like universities and organizations – by attaching digital identifiers to users, devices, and apps through certificate-based authentication. With a WiFi authentication certificate, every device is authenticated and interactions between devices and the network become encrypted, securing data from prying eyes and preventing unauthorized access, data interception, and other security risks. Plus, using WiFi Certificates allows you to identify each device to fine-tune network permissions and set access restrictions that align with your security strategy.
Which WiFi certificate best aligns with your needs? Check out our CA certificate options – we have solutions for nearly every scenario.
Convenience Without Compromising Security
See why universities, government organizations, and corporations choose WiFi authentication certificates to secure their networks.
Added Protection
Access to the WiFi network is only granted after each device’s identity is verified through certificate-based authentication.
Reduced Friction
Ditch the password hassle – once a WiFi certificate is set up, users won’t have to log in every time they connect to the network.
Improved Network Security
Prevent unauthorized access and potential attacks by encrypting connections and allowing access only to verified devices.
Make Network Security a Priority
Purchase one or many WiFi certificates to secure your organization against the latest threats to network security.

How WiFi Certificates Work
A WiFi certificate, also known as a CA certificate for WiFi, is a specialized device certificate that helps confirm the user’s identity, ensuring that only authorized people can connect to the WiFi network. Compared to other authentication methods, WiFi authentication certificates are generally considered more secure because they depend on unique digital signatures and private keys, both of which are far stronger than passwords. The digital signatures make it extremely difficult for attackers to imitate authorized users or use stolen credentials to gain access to the network. So, with a WiFi authentication certificate, sneaking in with stolen credentials or impersonating authorized users simply won’t fly.
Let’s suppose a WiFi certificate is tied to a student’s laptop at a university. The student’s device will use their WiFi certificate, public key, and private key to complete authentication and create a secure connection between the user or device and the university’s WiFi network.
In a nutshell, WiFi authentication certificates work in 3 simple steps.
1. The WiFi network admin sets up a special server that distributes digital certificates to authorized users and devices.
2. When a user/device attempts to join the network, they’ll have to show their digital certificate (i.e., WiFi certificate) to the network.
3. The network confirms the certificate is real and that the device has the corresponding private key – if it matches, the user/device will be granted access to the network.
