Missouri by the Numbers
Missouri has 3,273 government organizations, but only 723 (22%) have trackable websites. That means 2,550 government bodies have no online presence we can monitor for security.
Missouri earned an overall grade of D+ -- meaning most government websites and email systems lack basic security protections. Taxpayers in Missouri are at elevated risk for government data breaches, phishing attacks, and ransomware incidents.
