About Opendium

Opendium develops internet filtering and monitoring systems, firewalls and networking consultancy. Its products include the Opendium Web Gateway, a filter for 50 to 50,000 users, and the Opendium UTM, a unified threat management system that adds firewall rules for networks, subnets, IP addresses, users and groups.

Its customers are UK schools, which use the systems to meet the Prevent and Keeping Children Safe in Education guidance and the UK Safer Internet Centre's Appropriate Filtering requirements. Revenue comes from the filtering and firewall systems and from network design and support services for schools.

The company was established in 2005 and is based in Bruton, Somerset. Its engineers provide technical support, and it offers network consultancy for school networks, including BYOD and visitor networks.

Product: Opendium Web Gateway and Opendium UTM systems for web filtering, monitoring and firewall protection, plus network consultancy.
