From the CNDA FAQ....
 
7. I am deciding between attending a training on CEH or CNDA. Which one should I go for?

You should take the CEH training unless you work for an US government department and they approve you to take the CNDA course instead of CEH.

8. Can I obtain CNDA certification?

No. The CNDA certification is awarded only to employees who work for United States Government and Military Agencies
