What Cisco Does
Cisco manufactures and sells the backbone hardware that runs enterprise networks globally. Their product portfolio spans physical network switches and routers (Catalyst series), security appliances (ASA, Firepower, ISE), collaboration tools (Webex), and cloud-native platforms (Meraki, ACI). Revenue is 50% hardware, 40% software/subscriptions, 10% services.
Cisco dominates enterprise networking with ~55% routing and ~40% switching market share. Competitors include Juniper, Arista, and Fortinet, but Cisco's installed base ensures deep customer lock-in. The certification program supports both operators maintaining existing infrastructure and architects designing new networks. CCNA is a de facto prerequisite for networking career progression.

Why Cisco Matters in 2026
Cisco certifications dominate enterprise IT hiring. LinkedIn shows 48,000+ open Cisco/CCNA jobs globally, making it the second-most-requested networking credential after CompTIA Network+. Fortune 500 financial services, government, and telecom organisations mandate CCNA for network operations roles. Banks including JPMorgan Chase, HSBC, and Barclays employ thousands of Cisco-certified engineers.
Cisco certification is mandatory for government contracts, especially defence and critical infrastructure. DoD 8570 and UK GCHQ security clearance requirements often explicitly list CCNA or CCNP Security. The CCIE is the gold standard for network expert roles and commands premium salaries.
The certification ecosystem is exceptionally healthy. Cisco invests heavily in learning platforms and maintains one of the most vibrant communities (Reddit, Discord, YouTube channels with millions of subscribers). Exam content is updated annually. CCNA remains secure; unlikely to be retired. CCIE roles remain in strong demand and are increasingly specialist (Security, Data Centre, Service Provider).

Outlook
Cisco remains the dominant networking vendor but faces headwinds from software-defined and cloud-native approaches. The company is investing heavily in AI-driven networking and security-first design. For certification professionals, exam content will evolve to include SD-WAN, intent-based networking, and cloud-hybrid architecture. The CCNA remains secure. CCIE roles remain in strong demand but are increasingly specialist. Professionals should expect exam content to shift toward hybrid cloud and security within 12–24 months.
Frequently Asked Questions
Q: Is Cisco worth investing in for my career? Yes—if you want a networking career. CCNA is the industry standard, and enterprise demand is robust. However, if interested in cloud infrastructure or DevOps, pair Cisco with cloud certifications (AWS, Azure).
Q: How often do Cisco certs expire? All role-based certifications expire after 3 years. Renewal requires passing a renewal exam or a higher-level certification exam. Cisco offers free practice exams and online test engines.
Q: Are Cisco certs recognised in South Africa? Absolutely. CCNA and CCNP are required or strongly preferred by all major SA banks, telcos, and government agencies. Remote opportunities with global firms (Accenture, Deloitte, EY) are common.
Q: What's the best cert to start with from Cisco? CCNA. It's the entry point and prerequisite or strongly recommended for all CCNP specialisations. Expect 3–6 months study with hands-on lab experience.
