Reviews & Testimonial
I always treated networking as a black box. After this course I can actually open Wireshark and follow a TCP stream without panicking. The packet-reading sessions were the highlight.
The subnetting module finally made CIDR click for me. Doing it by hand and then verifying in a lab was exactly the practice I needed.
Perfect bridge from IT support into security. The DNS and DHCP walkthroughs explained things I had been faking an understanding of for years.
Beginner friendly but never dumbed down. Seeing the ARP spoofing demo made the theory stick instantly.
The three-way handshake and TCP flags finally make sense when you watch them live. Great foundation before moving into any security track.
