Why choose CIS Controls?

Small and medium-sized enterprises face two main challenges when implementing most information security standard and frameworks:

  1. Many information security management systems, such as ISO 27000 series, NIST, GDPR, SOC2, COBIT, HITRUST, and E-ITS (Estonian Information Security Standard – primarily designed for the public sector), are intended for large organizations, requiring significant time and resources for implementation.
  2. Frameworks often lack detailed guidance and a clear starting point, leaving small and medium-sized enterprises unsure of how to address specific information security topics.

CIS Controls framework is well-suited for small and medium-sized enterprises, offering a manageable approach to implementation. You can choose and implementation group with reasonable security measures tailored to your company's size and needs.

CIS Controls framework provides clear understanding of which cyber security measures offer maximum protection against today's cyber threats.
