Support

DenyFirst is run by a small team, and support is handled directly by the people who build it. There is no ticket maze and no bot. Email us and a human reads it.

How to reach us

• General and product questions: hello@denyfirst.com
• Billing, invoices, refunds: billing@denyfirst.com
• Security issues, in our product or found by our scanner: security@denyfirst.com (see responsible disclosure)

We aim to answer within one business day. We are a US company operating on Eastern time; a message sent overnight is answered the next morning.

What to send

If something went wrong with a scan, the single most useful thing you can include is the scan id shown in your dashboard. It lets us find exactly what happened without asking you a chain of questions.

• The scan id, and the app it ran against.
• What you expected, and what you saw instead.
• Never send us credentials. We do not need your API keys, service-role keys, or passwords to help, and we will not ask for them.

Billing

Charges appear on your statement as DENYFIRST. If you see a charge you do not recognise, email billing@denyfirst.com before disputing it. We would rather refund you directly than have you spend a month in a chargeback process.

Every paid month is covered by an unconditional 30-day money-back guarantee. Ask within the window and we return it in full, whatever the scans did or did not find. The exact terms are on the legal page.

What support can and cannot do

We can help you read a report, understand a finding, work out which rule to change, and get a scan running against a backend you own.

We cannot scan an app you have not proven you own. That is not a policy we can make an exception to: authorization is bound to the backend project through the provider, and support has no override. If you have lost access to a project you genuinely own, recover it with your provider first, then connect it here.
