VoIP Security & Encryption

Voice over Internet Protocol (VoIP) is one of the fastest growing segments in networking technology. Companies are moving their telephone communications from their traditional Public Switched Telephone Network (PSTN) to modern converged IP networks that offer high-speed access and lower costs.

Since VoIP utilizes the shared infrastructure of an IP network, any VoIP communication is subject to the same security vulnerabilities as any other form of data on a shared infrastructure. These security concerns were addressed in the National Institute of Standards and Technology's (NIST) paper Security Considerations for Voice over IP Systems:
"The prevalence and ease of packet sniffing and other techniques for capturing packets on an IP based network makes encryption a necessity for VoIP."
Until now, the biggest issue with VoIP security has been the tradeoff between protection and performance. Standard link encryption and the use of VPNs added latency, degrading VoIP call quality to the point where companies were forced to abandon VoIP encryption. The same NIST report mentioned above suggests that the way to negate the protection vs. performance tradeoff is with improved security policy and encryption key management.

the CipherOptics encryption solution


CipherOptics' VoIP encryption solution delivers just that. Whether you need to protect a single link, or your entire network, we eliminate the complexity of encrypting today's networks.

Our solutions combine standards-based, wire-speed encryption appliances with CipherEngine, the only policy definition and key distribution technology designed for multi-node networks. Together, they give you the highest level of data protection at the lowest total cost.

With CipherOptics, you get a VoIP encryption solution that is:
  • High-speed - Operates at wire speed to meet your bandwidth requirements
  • Low-latency - Does not add jitter to your VoIP communication
  • Transparent - No need for router upgrades or infrastructure changes
  • Quick to install and easy to manage - Will not disrupt network or application performance

    • The case study below details how we helped a U.S. regional bank secure their VoIP communications between their 250 branch locations.
