SMB Protocol Explained

Switching from open-source SMB to Visuality Systems’ jNQ, a global pharma leader modernized its Java-based file transfer, achieving enterprise-grade security and long-term support.

By integrating YNQ, a leading CPE manufacturer enabled telco carriers to deliver value-added storage services, now deployed in over 15 million units.

After Seeburger gained some experience with an open source SMB library, a growing customer base demanded a more robust solution. This was the main driver to look for an independent implementation of SMB3 library, like Visuality Systems’ jNQ.

Metrohm chose Visuality Systems to upgrade existing connections from SMB1 to SMB3 with fully supported software libraries, without changing the application.

If your SMB-enabled Java application is still scanning directories to detect changes, you’re likely consuming more resources than necessary. SMB Notify is the right way to track file system updates and it’s supported by jNQ’s Java SMB stack.

Cryptic exceptions and tricky platform differences are common when trying to integrate SMB file sharing into a Java application. What are the most common roadblocks? How can you work around them?

A KDC (Key Distribution Center) Proxy allows secure communication with a Kerberos KDC, typically over HTTPS, enabling clients to obtain Kerberos tickets when direct access is not available.

Transitioning from NTLM to Kerberos is not just a best practice, it’s an essential step in building a secure authentication infrastructure. CVE-2025-24054 is the latest example of why this shift cannot be delayed.

While CIFS and SMB are often viewed as synonymous, there are significant technical and practical differences between them. SMB outclasses CIFS in every key area, especially when it comes to performance and security.
