VoIP is as safe as traditional telephone systems as long as the internal IT infrastructure is secure. Many VoIP providers have added security to ensure calls cannot be intercepted by hackers. All exchanges have strong security as the hosted phone platform is a closed, data-encrypted system.
According to a report published by Accenture Security, as many as 70% of business leaders are concerned about cyber security. This inevitably means that there are going to be some questions asked about VoIP security.
The truth is that VoIP is as secure as your current IT infrastructure. If your business already has strong protections in place, there should not be an issue.
In addition, most high-quality VoIP phone system providers have a data-encrypted system to ensure that calls cannot be intercepted by hackers.
