Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.\nFor more information refer to the Schneider Electric Recommended Cybersecurity Best Practices document. \n",

When outside of a trusted Wi-Fi environment, we strongly recommend the use of a secure communication channel, like a secure VPN service, to remotely access the product. Customers will receive reminders to utilize secure VPNs upon opening the Ritto Wiser™ Door app. For residential use, we recommend placing this product on a segmented network separate from the main home Wi-Fi to ensure privacy and security.",
