Our team at Wissen Research is proficient in conducting tests across various abstraction layers in the OSI model using packet sniffing and probing tools such as Airpcap, Wireshark, Charles Proxy, Fiddler and mHotSpot. We can also perform GUI or functionality-based testing, depending on the specific case requirements, to supplement the evidence obtained from product documentation and other sources such as code review.
