wolfSSL 2019 Annual Report

We not only remained far ahead of our competitors in 2019, but we also proceeded to extend our lead with massive success and growth. We grew our business dramatically, primarily based on our technological superiority and ongoing investments in testing and quality. We delivered TLS 1.3 ahead of the market, MISRA-C cryptography for the automotive market, FIPS for our government consumers and DO-178 for avionics. We also remain the best-tested product on the market, as witnessed by our additional fuzz testing resources from both internal and external sources. We have also been through a number of additional code audits from our large consumers. Finally, we engaged some of the best code auditors and testers in the world to review our code. Lots of testing and lots of eyeballs have come together to produce the best-tested TLS and cryptography code on the market today. Thank you for your interest in wolfSSL! We are off to a great start in 2020 and will strive to live up to your expectations again in the rest of 2020!

Reminder: If your TLS and cryptography provider does not do fuzz testing, you are exposed.
