Toan Bill

Hello there! 

I am Bill Toan.

I have a master degree in computer system information. I've been a Cisco instructor since 2010. I hold CCNA, CCNP security and Security+ certification. My favourite teaching courses are CCNA and CCNP Security. I come from a background of network security engineer, and now I am focusing on IoT and OT security and applied machine learning techniques on network security. 

I have worked for over 14+ years on building enterprise security solutions using Cisco products. I have been a super-moderator of a network security forum named whitehat for more than 10 years.  I love sharing my experience to students and inspire them to the cyber security world.

Happy Learning!
