Everything Shield stops, everything it speeds up, and how you prove it
One DNS layer filters content, stops threats and strips ads for pages up to 500% faster, across every device on every network you run, with a policy per SSID, VLAN and venue and one dashboard that proves exactly what was stopped. Nothing to install, nothing to rack.
- Up to 500% faster pages, ads stripped
- 241k threats blocked a week at St George's
- Threats flagged up to 10 days earlier
- 30-day free trial
- Filtering to the Internet Watch Foundation bar

Stop the threat before the connection starts
Shield stops the lookup before a connection starts. At St George's Healthcare NHS Trust it blocks around 241,000 threats a week on the guest WiFi. Threats means malware, phishing and command-and-control lookups stopped by Shield.
- Blocks command-and-control callbacks from infected devices
- Blocks known phishing and malware domains at the lookup
- AI detection flags threats up to 10 days before standard blocklists
- Fails closed, across multiple data centres
- Protects every device, including iOS and Windows, with no agent

Ad blocking
Faster pages and less data, on every device
Most security costs you speed. Here, ads, trackers and bloatware never arrive. Pages load up to 500% faster and web traffic drops 20 to 40%, so shared WiFi carries less contention and lower data costs.

Policy
A policy per SSID, VLAN and venue
A guest network, a staff network and a children's area never share one set of rules again. Each network and each site carries its own, and each changes by the hour.
- Set per SSID, as a network setting or a DHCP change on your controller
- Separate rules for paid and free WiFi
- Change by time of day and day of week
- Start from a ready-made policy or build your own lists

Feature questions
Can Shield enforce family-safe browsing?
Yes. It blocks adult, gambling and other content categories, enforces Safe Search on Google, Bing and YouTube, and supports allow and block lists per venue. Filtering meets the bar set by the Friendly WiFi and Internet Watch Foundation standards.
Does ad blocking speed up the network?
Yes, and it is the reverse of what most people expect. Stripping ads and trackers at the DNS layer makes pages load up to 500% faster, cuts web traffic by 20 to 40%, uses up to 44% less data and makes up to 62% fewer DNS queries.
Can I show my own page when a site is blocked?
Yes. Anyone who reaches a blocked site sees your branded block page instead.
Can guests get round it with a VPN or encrypted DNS?
Shield answers every DNS lookup on the network it protects, on every device, with nothing on the device to switch off. A Shield expert shows you exactly how your network handles VPNs and encrypted DNS before you trial.
