CMS Security Vulnerabilities Statistics in Vietnam (2026)

Vietnam's web ecosystem in 2026 remains heavily reliant on WordPress, which accounts for 70% of CMS usage. However, nearly half of the websites still operate on outdated CMS versions, exposing them to known vulnerabilities. The average Vietnamese website has over three vulnerabilities, emphasizing the need for better security practices. The rise of website builders now comprises 35% of sites, reflecting a shift towards easier, less secure development tools.

Cybersecurity awareness in Vietnam must increase as vulnerabilities persist across many sites. Many businesses underestimate the risks associated with outdated CMSs, often neglecting regular updates. The growing adoption of website builders offers convenience but also introduces new security challenges. Strengthening security protocols and regular patching are essential steps to protect Vietnamese digital assets in 2026.
