Subject: D-Link Removes Switch Firmware Backup Function to Strengthen Product Security with Digital Signature Implementation 
Date: November 24, 2025 

D-Link, a leading provider of networking solutions, announced the complete deployment of a digital signature from switch firmware backup function removal. This strategic move marks a significant step in D-Link's ongoing commitment to cybersecurity, offering an unchangeable seal of authenticity and integrity for its products. 
This advanced security measure acts as a cryptographic guarantee, ensuring that every piece of software released by D-Link is genuine, unmodified, and directly traceable to our secure source. The deployment provides three main benefits: 

Guaranteed Integrity: Each firmware update is cryptographically signed. Any attempt to alter or corrupt the software—whether during transit or storage—will be detected, preventing the installation of compromised code and safeguarding users from potential malware or ransomware. 

Verified Authenticity: Users and devices can now confidently verify that the software comes from an official D-Link source. This eliminates the risk of installing counterfeit or malicious firmware from any unauthorized modifications. 

Enhanced Trust: By establishing this security foundation, we give our customers and partners peace of mind, knowing their network infrastructure is built on products that are secure from the start. 

This update is a vital part of D-Link's layered security approach, designed to protect users throughout the entire product lifecycle.
