While HIPAA compliance is not required for this software, the creators are aware of HIPAA transaction best practices as the founder who works as Civil Engineer e.g Critical Infrastructure and the Software Lead worked in the Healthcare Industry for several years. That is why SERALYNX LLC focus more on implementing the best security practices rather than having a fancy user interface.
Note that to determine HIPAA compliance, a rigorous audit will need to be performed to see how your organization is set up in terms of security implementation of different security control attributes. If you have strong security controls that can pass the HIPAA compliance audits, then using this software is a good complementation for your organization’s security.
No, this is due to the fact that the other edition is in different settings for security purposes. Note that recreating such settings, username and password is easy if you decided to use a higher edition.

Note: Software Delivery May Take 8-24 Hours
Temporary download link will be sent via email within 15 minutes. If you encounter a download issue, please contact us. If Windows Defender flags the zip file, this is a false positive, as long as you verify the CRC64/SHA256, you are safe.
Caveat: Disposable email MAY NOT always work. That said, if you are diligently interested in this product and have nothing to hide, please use a non-disposable one. This website also uses Imunify360 with Proactive Defense enabled to scan malicious scripts.

Security is one of PORTA SFTP SERVER’s top priorities, with that said, the app itself is very easy to use but we’ve implemented rigorous protection to it as well. With the certificate authorization protection, you will have the additional security below.
Note: Do not share your private key or password of your certificate with anyone.
