This work proposes the Crypto-Agility Maturity Model (CAMM for short), a maturity model for determining the state of crypto-agility of a given software or IT landscape. CAMM consists of five levels, for each level a set of requirements have been formulated based on literature review. Initial feedback from field experts confirms that CAMM has a well-designed structure and is easy to comprehend. Based on our model, the crytographic agility of an IT landscape can be systematically measured and
