Contact questions
Response times, what to prepare, and how your details are handled.
How quickly will someone respond?
During business hours — Monday to Saturday, 9:00 AM to 7:00 PM Central Time — the median callback is under 60 minutes. Requests received outside those hours are answered first thing the next business day.
Is the quote call really free?
Yes. The discovery call, the written quote and the deployment plan are all free and carry no obligation. Setup assistance is included with a license purchase rather than billed separately.
What information should I have ready?
A rough device count, the operating systems in use, the names of any business-critical applications, and details of security software currently installed. If you do not have all of that, we can work with what you know.
Can I contact you about an existing order?
Yes — email support@coredefendsystem.online with your order reference, or call and quote it. Existing clients can also reach their assigned deployment specialist directly.
Do you offer support outside your business hours?
For business clients with an active deployment we arrange cover for critical issues. Tell us your requirements during the quote call and we will confirm what is available for your tier.
Will you contact me repeatedly after I submit the form?
No. We contact you to answer your request. If you do not want to proceed, tell us once and we close the file. We do not sell or share your details with third parties — see our Privacy Policy.
Where are you located?
Our registered office is at 2200 Enterprise Security Plaza, Suite 410, Austin, TX 78701, US. All deployments are handled remotely, so clients are served worldwide.
