For this, we are identifying the companies that are ISO 27001 certified. For this, we have chosen the companies, BSI, Cyber sapiens, Consilium Labs, Bureau Veritas and TÜV SÜD America. We have analyzed how ISO 27001 has helped the companies for protecting the data, risk management and its compliance.
