Smart City IoT Security Solutions

Maximize smart grid efficiency by protecting real-time
data sharing using PKI-based security solutions.


Why Smart Cities Need Security

Organizations collecting data from smart meters, switches, and other sensors can reduce electricity, water, and gas usage, save money, and institute more efficient demand response-type programs, including quicker outage checking and resolution. However, with so many different devices and services connected, there are risks of large data loss, system tampering, and downtime.

How to Secure Smart City IoT

A Public Key Infrastructure (PKI) solution secures smart city IoT by using digital certificates to authenticate a device, system, or network, encrypt all communications, and uphold data integrity.

PKI Addresses Common IoT Security Challenges

Electrical engineers, software engineers, and manufacturers are just some of the roles tasked with the important job of deciding the best way to secure data in an IoT ecosystem.

Using the DigiCert Cloud PKI service and with knowledge from our PKI engineers, we can help you design a customized solution, implement it on your desired timeline, and succeed from the start.
