Common Criteria evaluations can vary significantly in duration, depending on the complexity of the product or system being evaluated or the maturity of the vendor in developing the necessary product or system artefacts to support the evaluation process. A typical Common Criteria evaluation however can be expected to take between 6 - 12 months. Engagement of a licenced Common Criteria laboratory such as Viden, to provide formal training on the Common Criteria process or advice on artefact development requirements, can significantly reduce evaluation delays caused by product or documentation re-work during the evaluation process.
