adaptmicrosys is a proactive cybersecurity & HPC solution company.

Our solutions are to immunize processors (i.e., CPU/GPU/DSP/AP/MCU/etc.) from all cyber threats. This is the cybersecurity of the future. Our immunized Unit (iU) with our IPs and proprietary technologies transforms any types of vulnerable processors into immunized versions (i.e., immunized processing units (iPUs)) by randomly switching between millions of machine languages at any time. The iPU provides solid protection. But what’s more, it actually contributes processors run faster, consume less energy, and cost less to manufacture, all while guaranteeing code compatibility.

adaptmicrosys’ vision is this:

We will end this cyber pandemic without endless vaccination or worries about future variants;

We will make cybersecurity comprehensive, foolproof, and accessible for all; and

We will no longer have to imagine a world without cybercrime.
