Hugslock exists to defeat the inadequacy of current manhole security arrangements and to provide the most advanced monitoring of critical infrastructure available. The vulnerabilities associated with traditional and manual locking covers have been reported by publications worldwide in recent years. The Sun Newspaper included the following article:
