The ISMS component hierachy

When building an ISMS, it's important to understand the different levels of information hierarchy. Here's how Cyberday is structured.

Framework

Sets the overall compliance standard or regulation your organization needs to follow.

Requirements

Break down the framework into specific obligations that must be met.

Tasks

Concrete actions and activities your team carries out to satisfy each requirement.

Policies

Documented rules and practices that are created and maintained as a result of completing tasks.

Never duplicate effort. Do it once - improve compliance across frameworks.

Reach multi-framework compliance in the simplest possible way‍

Security frameworks tend to share the same core requirements - like risk management, backup, malware, personnel awareness or access management.

Cyberday maps all frameworks’ requirements into shared tasks - one single plan that improves all frameworks’ compliance.

Do it once - we automatically apply it to all current and future frameworks.
