Every time you connect to Wi-Fi, send an email, or join a video meeting — there’s a good chance Cisco technology is behind it.
Cisco powers the invisible infrastructure of the modern internet, connecting businesses, cities, and cloud systems across the globe.
And if you want to speak the language of modern networking, there’s one certification you must know:
CCNA (Cisco Certified Network Associate).

Cisco Systems, founded in 1984 in California, is the world’s largest networking, cybersecurity, and data center technology company.
Its routers, switches, and firewalls are the backbone of global enterprise networks.
