Janet Network resolver
Benefit from advanced DNS and malware protection by using our protective DNS service, available at no additional cost to member and customer organisations connected to the Janet Network.
The Janet Network resolver helps to protect your organisation by preventing your devices and network from accessing known malicious or compromised websites.
When you configure your systems to utilise the Janet Network resolver, you benefit from an immediate security improvement, we’ll help you to maintain a safe digital environment for your connected students, staff and users.

These feeds are continuously curated by our cyber threat intelligence team, ensuring that the Janet Network resolver is able to adapt to emerging threats.

Case study: Trafford College Group’s belt and braces approach to cyber security
The Trafford College Group were already in the middle of a programme to upgrade their web filtering and firewall systems when their Jisc relationship manager recommended adding Janet Network resolver.
“Janet Network resolver helps to protect our devices and any other devices that connect to our systems including students’ own devices and anyone using the guest wifi.”
“We see it as an added-value ‘belt and braces’ service. It gives us extra reassurance and it’s something we can take advantage of as part of our Jisc subscription.”
Dave Fitton, TCG’s director of IT and digital services
