All the Greek patheon have dual Latin/Greek names. Mercury/Hermes etc.
It’s pronounced about the same in either case. “Cerberus” in Latin is pronounced “Kerberus”, just like “cent” is actually pronounced “Kent”.
That might be something they would be willing to change their name to. It's also a commonly used name although probably nowhere near as bad to google as Kerberus.
I think Siemans has that under the Cerberus Pyrotronics brand.
