To protect from Malware and phishing, do not open or click on any attachments in suspicious emails. If you are concerned about an email you receive from ASC, please call us and we will confirm that it was sent by us. ASC support will send emails with sensitive data securely. You could receive an email from ASC support that indicates you need to setup an account or request a one-time passcode each time you receive a secure email from ASC support members. If you have questions about any email from our staff or specifically secure emails please contact us.
To insure the security of your sensitive client information, we ask that ALL Support requests come via this *Secure* CSC Client Support Center web page, where data is encrypted when transferred. This is particularly important when sending us portable copies of plans. Since email transmissions are not as secure, we ask that you avoid sending emails directly to Support or an individual on the Support team. We strongly recommend that you strip sensitive data from files and use the option to mask or print blank SSNs when creating portable copies of cases or any pdfs of reports.
