The WCNA is good for three years, but certification holders must obtain a total of 20 continuing professional education (CPE) credits each year in order to maintain their credentials in good standing. To achieve this credential, candidates must pass one multiple-choice exam. The Wireshark Certified Network Analyst (WCNA) recognizes knowledge of network sniffing and analysis using Wireshark, as well as TCP/IP network communications, network troubleshooting and network security. The Wireshark Certified Network Analyst Program strives to test a candidate’s knowledge and ability to troubleshoot, optimize and secure a network based on evidence found by analyzing traffic captured with the world’s most popular and widely-deployed analyzer, Wireshark.įounded in 2007 by major networking geeks Gerald Combs and Laura Chappell, Wireshark University offers only a single certification but makes it very much worth your while.
