National cybersecurity strategy (NCSS) is an essential element as cybersecurity is needed to protect and enable digital economy. This article seeks to gain insights on the relationship between the development of the NCSS and the success of digital economy of the nation based on literature from journal articles, global reports, current industry happenings and market trends. NCSS of nine nations were analyzed centered on digital economy success.

In order for digital economy to thrive, the digital confidence of the stakeholders should be high. Nations with high digital confidence depend less on the national level NCSS to strengthen the trust and confidence in digital space. Nevertheless, the NCSS is still a need as a foundation for long term strategy to cement the cybersecurity of the nation, as cyber threats and risks keep evolving and will remain a challenge. A country like Singapore is intensifying its efforts and commitment in national cybersecurity. The existing top ten nations in digital economy has NCSS providing the necessary foundation for digital economy to flourish further.
