In general, we're big supporters of the open source movement. But it can be pretty difficult to use open source security tools effectively in constrained device environments. When you're evaluating security solutions for your next embedded device design project, it's important that you understand the Total Cost of Ownership (TCO) of tools like OpenSSL and OpenSSH. Often, you'll discover that licensing a fully-supported professional solution like Mocana's NanoSSH - which has been purpose-built specifically for embedded device environments - is, in the end, less expensive than trying to "shoehorn" OpenSSH into your device. You'll get much better performance out of Mocana's software, too. And for the record – all of Mocana’s security solutions are based on open standards, and are available to you as full source code at no extra charge. You’ll also find that Mocana’s SDKs offer an RFC feature-set depth and breadth that you won’t find anywhere else.
The table below will help you calculate the Total Cost of Ownership incurred by building, porting and/or integrating a typical OpenSSL or OpenSSH implementation. Complete the inputs table with numbers specific to your business, and your results will automatically be calculated in the 'Results' table below. Don't worry about getting your numbers exactly right; make your best guess and you can always adjust the figures later.
