Customer Testimonials

"We have recently started using opendnp3 to replace the previous library that we used in our DNP3 master driver. We are very impressed with the functionality, usability and performance of the library."

"I'd really like to use opendnp3 instead if possible, not only because it doesn't cost $15k each for the master/outstation components, but because it's so much nicer to use!"

"I'm quite impressed with how robust this library is in dealing with such a horribly implemented device. It looks like I'm going to have to have a long talk with the people that manufacture the box."

"From our initial prototypes our impressions are very positive; the code is well structured, easy to read and the system looks like it will scale much better."

"We have found the Automatak C++ opendnp3 implementation invaluable in our DNP3 master and outstation simulations focused on cybersecurity. A single easy-to-use client can simulate either master or outstation and multiple peers can use the same compiled program to support end-to-end testing."
