Newtek is firmly committed to providing the highest level of security for out merchants developers and partners. In 2015 the PCI Security Standards Council mandated that merchants discontinue the use of Transport Layer Security (TLS) 1.0 by June 2018. The TLS 1.0 encryption standard no longer meets minimum security requirements due to vulnerabilities in the protocol that cannot be fixed. It is critically important that all entities upgrade to a TLS 1.2+ and disable any fallback to TLS v1.0 as soon as possible.
Newtek will begin phasing out TLS 1.0 and 1.1 over the next few months. The date each environment will be phased out is listed below:
|Sandbox||sandbox.newtekgateway.com||February 1, 2018|
|Primary URL||secure.newtekgateway.com||June 29, 2018 at 10 AM PST|
We encourage merchants and developers to migrate an outdated software as soon as possible.
Testing Your Update
The easiest way to test that you are no longer using an insecure encryption protocol is to test against the our sandbox environment after the insecure protocol has been depreciated on 2/1/2018.

Below we have outlined some environments we have determined may be effected by this change as well as some workarounds for each.
.Net Framework 3.5 and below does not support TLS 1.2.
.Net Framework 3.5.1 Microsoft Support has an update and instructions: https://support.microsoft.com/en-us/help/3154518/support-for-tls-system-default-versions-included-in-the-net-framework
.Net Framework 4.5 supports TLS 1.2 but does not use it by default, the following needs to be added before connecting:
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
4.6+ Should support TLS 1.2 by default.
If you are using the DotNet DLL, you will not need to recompile your software, just update the .NET Framework as noted in the section above. Then drop in the replacement DLL file listed below according to the current version you are using.
|If you are using version...||Update to version:|
|Versions 1.** or 2.**||DotNet DLL 2.0|
|Version 3.0 and above||DotNet DLL 4.0|
DotNet DLL Scanner Tool
The scanner tool listed below should locate your current DLL version, update it to be TLS 1.2 compatible and update your .NET Framework as well. Simply download and run the tool.
.NET Payment Engine SDK
If you are using the .Net Payment Engine SDK, you can use the instructions above to update your .Net Framework, or download the latest version of the .NET Payment Engine SDK here.
If you are using the Mac or Linux versions of EpayCharge, no updates are necessary.
If you are using the Windows version of EpayCharge, you will need to download the newest Windows version of EpayCharge which can be found here.
For more information on installing new EpayCharge version 3.3 and setup click here.
Please Note: USB swipers must be encrypted to be compatible with the new EPayCharge version.
If you already have version 3.1 installed, EPayCharge will update your current version to the newest version and save your previous history.
If you already have version 3.3 installed, and you run this installer, you will be prompted to either remove the existing version or repair the existing version.
If no previous version is detected, the program will be installed normally as a new program with no history.
If you process transactions on the merchant console through your browser, you will need to verify that the browser you are using to process payments is TLS 1.2 compatible. To test your current browser compatibility you can use this third party browser testing service from Qualys' SSL Labs: https://www.ssllabs.com/ssltest/viewMyClient.html
Please Note: that this test and some others may not run successfully depending on your exact system and network configuration and should only be used as a guide.
These browsers do support the latest encryption standards:
You can also use the guide below to check to see if your current browser is compatible.
