From 2004 to today, there have been a number of dramatic data breaches, as shown in this interactive data visualization from InformationIsBeautiful.net. Organizations as varied as AOL.com and the 2016 Clinton presidential campaign have had records stolen.
In this climate, Avalara is working to ensure your records remain secure.
One of the upcoming Avalara security changes is to switch the trusted certificate chain from SHA-1 to SHA-256. These chains are used for encryption to protect your communications with Avalara services. The changes will be finished by May 18, 2017.
Avalara has organized this upgrade so most customers won't see any change in stability and access to their AvaTax system. However, the company is being proactive to reach out and work with customers, ensuring a smooth transition. They have set up test URLs where your IT team can verify they have made the needed changes, so service will continue without any turbulence.
Details for your IT team (including the new certificate chains and the test URLs) are available from the Avalara Help Center.
