Point of Sale

Point of sale systems are a staple of the retail and service industry, allowing customers to conduct transactions via credit card or other digital payment methods.  Security of these systems is mandatory and critical.  As the best-tested cryptography and SSL/TLS implementation available today, wolfSSL and wolfCrypt are used to secure point of sale systems worldwide.

Home Energy Monitoring

wolfSSL and wolfCrypt are being used to develop home energy monitors being used in the cloud. wolfSSL is used to secure the connection between the device which resides at an individual’s home and the cloud used to store and process data. This allows individuals and companies to actively monitor their energy usage, take a more forward view on energy conservation, and gain control over something that was previously viewed only by power companies.

Electronic Games

wolfSSL has become a go-to solution for game developers wanting to secure online in-game communications. There are several companies actively using wolfSSL to secure the games that you play every day! wolfSSL’s support for stream ciphers, its portable nature, and its easy license model have made it perfect for gaming.


Database communication can be vulnerable if left unsecured, and the risk of data exposure is increasing with the growth in available data. For this reason, many individuals and companies use SSL and TLS to provide a secure communication link between database clients and servers. Having been built into some of the world’s largest database software, wolfSSL products are widely used throughout the world to secure database communication. Visit our Media Page to read our presentation on securing MySQL with SSL.


Although they may be small and extremely resource-constrained, the advent and proliferation of network-connected sensors has brought about a concern for communication security. wolfSSL has met that need by creating wolfSSL to be extremely small in size while maintaining fast speeds and a full feature set.


Voice over IP devices and networks are a natural consumer of SSL and TLS technology. Although the two fit together very well, the use of VoIP brings with it many challenges to an SSL library - including the need for high reliability and robustness under extremely heavy traffic loads. With a strong support team and a solid design, wolfSSL has met this challenge, and is currently being used to secure some of the most widely-used VoIP applications on the market.


wolfSSL has been integrated with and is being used to help secure several popular routers and router firmware packages.  The portability of wolfSSL allows it to be easily and quickly ported to new operating environments - in either the embedded or enterprise world.

SSL Inspection

Do you have a need to analyze or monitor SSL/TLS traffic?  It turns out that there are quite a number of people who need this functionality for one reason or another, including analyzing network problems, detecting network misuse by internal or external users, monitoring network usage and data in motion, and debugging client/server communication.  wolfSSL offers SSL Inspection (or “sniffer”) capabilities which are very easy to use.  For more information on wolfSSL’s SSL Inspection feature, please see Chapter 4 of the wolfSSL Manual.
