Tyler Technology

Dear Valued Tyler Client,

I’m writing to update you about Wednesday’s security incident with our internal phone and IT systems. Because this incident involved a malicious action by a third party, we have been working closely with independent security and forensic experts, in addition to our internal teams, to conduct our investigation. We have also been in direct contact with the FBI, and we are cooperating with their investigation.

We understand that any type of security incident is concerning to you. It doesn’t help that much of the media coverage has included inaccuracies and speculation without factual basis. This is still an active investigation, so we are limited as to what we can share.

Here are some important points we can confirm at this time:

• • After round-the-clock research and examination, all evidence continues to indicate that this incident was limited to our internal corporate network, including our phone systems.

  • There is no indication of unauthorized activity or compromise to client applications we host in our separate hosting data centers, nor do we believe that any client data or client servers have been affected.

  • All Tyler payment processing portals are hosted in the cloud and were not affected. We have detected no outages or suspicious behavior on our payment platforms.

We continue to treat this incident with the highest priority, as we complete a thorough response and secure system restoration. Once we are past this, we look forward to providing more detail about the findings of our investigation. Until then, please refer to the home page of our website at tylertech.com where we will regularly post updates in the “Questions and Clarifications” section.

We apologize for any concern or inconvenience and appreciate your patience and understanding as we work to bring our phone lines and support systems back online. Our Tyler employees are anxious to get back to business at full speed with the superior level of service you’ve come to expect from us.
