Security is a must for every cloud-based service that’s plugged into your business, and the attack vectors evolve every day. For an internet-connectrd application like VoIP, one that’s serving as the hub of your business communications, inside-out security measures are even more imperative. Do your due diligence on vendors to know where the responsibility lies for data stored in a cloud-based service, and if possible negotiate security terms into your contract. Look for services that offer end-to-end encryption, encryption for data at rest (if there is any), and not just basic authentication, but advanced options, too, especially multi-factor authentication and biometrics. The good news is that VoIP solutions are built for enterprise and many put a premium on their security stack.
Behind your firewall, talk to your IT staff and make sure security is top-of-mind there, too. Make sure your on-premises networking hardware is VoIP aware and has business-grade security features available…then make sure they’re enabled where they need to be. For example, virtual LANs (VLANs) are often used to segregate voice traffic for call quality reasons as having a dedicated network for that traffic means other network apps’ data can’t interfere and cause audio artifacts during calling or even dropped calls. But VLANs are also great for securing VoIP conversations as long as IT sets them up with that in mind.
