We can help as much or little as you want – e-Contego has many years of experience in regards to developing solid processes and procedures for various operational and Information Security tasks.
If you decide to perform all remediation on your own, as a partner, we do recommend regular checkpoints to ensure you are on track and that the remediation will satisfy the certification audit. ISO 27001 do require that certain mandatory documents/policies exist.
e-Contego can provide a set of policy templates that you can easily modify and use to create your own mandatory ISMS documents.
