Why does encryption matter?

GDPR 2018

The EU Data Protection Regulation coming into force in May 2018 will levy significant fines for businesses who fail to protect the data they hold. If you transmit personal data by telephone,  you should add an extra level of encryption to demonstrate that you are taking steps to adhere with the regulation.

Information Security

Calls made over the Public Internet are vulnerable to remote wiretapping.If you have an Information Security policy or are compliance driven you must protect your business communications from malicious hackers. The interception of sensitive information could see you suffering from intellectual property theft.


Organisations no matter how small amass sensitive information relating to all their stakeholders from customers, partners, suppliers, employees to investors. Not taking measures to protect this data from falling into the wrong hands risks damage to your reputation at the very least.

“You wouldn’t leave your laptop open on the train with all your critical business information for all to see.
Why do this with your phone?”
