No. While helpful, many successful security researchers are self-taught or come from non-traditional backgrounds. Demonstrable skills matter more than credentials.

With dedicated study, 12-18 months of focused learning can prepare you for entry-level positions. However, true expertise takes years.

Absolutely not. As software complexity grows and IoT devices proliferate, the need for automated vulnerability discovery is greater than ever.

Both are valuable. Web application fuzzing has more entry-level opportunities, while embedded/IoT fuzzing is more specialized and often better compensated.

Very important. It demonstrates real-world skills and gives hiring managers confidence in your abilities.
