The National Institute of Standards and Technology (NIST) was founded in 1901 and is now part of the U.S. Department of Commerce. NIST is one of the nation's oldest physical science laboratories.
The NVD is the U.S. government repository of standards based vulnerability management data represented using the Security Content Automation Protocol (SCAP). This data enables automation of vulnerability management, security measurement, and compliance. The NVD includes databases of security checklist references, security-related software flaws, misconfigurations, product names, and impact metrics.
So, in a nutshell, if a vulnerability in any software has ever been identified, it will be included in the NIST NVD.
Now, we claim that Syncplify Server! is the only commercial SFTP/FTPS/HTTPS server that doesn't have any known vulnerability in the NIST NVD, and we don't ask you to take our word for it. You can verify it yourself:
Search the NIST NVD website for Syncplify Server! or even just Syncplify: you'll find exactly zero results
Now try and search for any other enterprise-grade competitor in the same database: that's right, Syncplify is the only one with no known vulnerabilities (and has never been hacked since its first inception in 2013)
