At Microsoft, we invest a lot of time researching and investigating possibilities in our journey to memory safety. Because the massive majority of existing codebases are written in unsafe programming languages, the task of protecting legacy code is very important. Hardware solutions are an attractive approach because they introduce very powerful security properties with low overheads compared to purely software solutions.
