Client Face
"Guardian is one of the best auditors we have worked with so far. Paying per vulnerability helps ensure that goals are aligned and we wish this format was more widely adopted. Contract code was thoroughly vetted with high quality reports including detailed recommendations and working proof of concept tests to demonstrate issues."
