CallGuard is our phone management tool that ensures you don’t fall victim to the ever-growing threat of phone fraud and hacking. CallGuard can protect your business from criminals hacking into your phone system and making expensive international calls using your phone number.

With CallGuard activated on your lines, our network detects unusual usage and automatically bars the line, meaning that you are only ever liable for the calls up until the bar is in place, giving you peace of mind that your service is being constantly monitored.
