Hello, I am a network security engineer working for the largest ISP in my country and also a CCNA trainer at a local IT training company. I deal on a daily basis with Cisco and Fortinet networking devices, including Cisco IOS, IOS-XE, IOS-XR, NX-OS, Fortigate and Fortianalyzer. I am also familiar with Juniper Networks Junos and VMware and various tools used for network design and management.
