Why people choose DSIFD School for their career

The Network Security & Firewalls course gave me a strong foundation in configuring and managing firewalls. The practical labs on setting up IDS/IPS and analyzing network traffic were amazing. I now feel much more confident securing enterprise networks!

This course explained complex firewall concepts in a very simple way. I loved learning about VPNs, NAT, and how to block suspicious traffic. I even applied the skills to secure my home network and passed my Network+ certification exam.

If you want to build a career in network security, this is the course for you. I enjoyed the hands-on practice with different firewall types and real-world attack prevention techniques. Now I’m ready for my first role as a network security analyst!

I was struggling to understand how firewalls actually protect data flow until I took this course. The instructor showed step-by-step configurations using Cisco and pfSense firewalls. I feel ready to implement secure network solutions for any organization.
