How does Telnyx prevent and detect fraud?
Currently, Telnyx detects fraud by using a statistical model to detect outliers in the minutes of use data within a certain time frame.
To do this, we aggregate the minutes of use (MoU) for each account during a specified period of time. Then, we calculate the standard deviation of each data point and compare that to the mean MoU for each account. If the MoU is more than a certain number of standard deviations away from the mean, an alert is logged in our cache and a support representative will respond accordingly.
To prevent fraud, we suggest you take a number of measures to protect your account.
1. Secure your account passwords.
2. Review access logs on a regular basis
3. Restrict web access to your PBX/VoIP system
