Critical infrastructure companies must comply with a range of cybersecurity regulations and standards, including the NIST Cybersecurity Framework, NERC CIP (for energy), CISA guidelines, and other local regulations depending on the sector. These standards ensure that critical infrastructure systems are protected from cyber threats and are resilient enough to continue functioning even in the face of attacks. For companies working with defense contracts or handling Controlled Unclassified Information (CUI), CMMC 2.0 plays a key role in ensuring compliance and safeguarding sensitive information. Compliance with CMMC 2.0, along with other standards, ensures that critical infrastructure systems meet rigorous security standards, reducing the risk of data breaches, service interruptions, and potential national security threats.
