In an era where data privacy is paramount, securing your home or small business network storage is non-negotiable. Synology Network Attached Storage (NAS) devices, running the intuitive DiskStation Manager (DSM) operating system, offer robust features for file sharing, backups, and media streaming. However, by default, they use self-signed certificates that trigger browser warnings and leave connections vulnerable. Enter SSL/TLS certificates from trusted authorities like GoDaddy—these provide encrypted, verified connections, ensuring your data stays safe from eavesdroppers.
This guide focuses on installing a GoDaddy SSL certificate on a Synology NAS running DSM 7 (the current standard as of late 2025). Whether you’re accessing your NAS remotely via a custom domain or just want to eliminate those pesky “Not Secure” alerts, follow these steps carefully. We’ll assume you have administrative access to your NAS and a GoDaddy account. If you’re on DSM 6, the process is similar but check Synology’s legacy docs for tweaks.
