Cybersecurity technologies and best practices have rapidly evolved alongside the digital world, providing a wide array of tools to address vulnerabilities and threats. However, security breaches remain a significant concern for 21st-century businesses. According to the Federal Bureau of Investigation Internet Crime Report, cybercrime losses reached a [record $12.8 billion in 2023](https://www.ic3.gov/Media/PDF/AnnualReport/2023_IC3Report.pdf).

Given this challenging context, introspection is crucial. Is your company doing enough to protect itself and maintain robust **network security**?

To assist organizations in facing these challenges, ne Digital's experts have developed a comprehensive **Cybersecurity Incident Response** checklist framework based on the five core functions recommended by the National Institute of Standards and Technology (NIST):
