All-round protection for your VoIP network

The advantages of the Session Border Controller
How to turn your VoIP network into a fortress
Internet-based telephony offers many advantages, but also carries certain risks. The secunet SBC ensures that no one can infiltrate the internal network unnoticed.
Our session border controller securely connects and links VoIP networks with different security levels. At the network border, it serves as a central access point for VoIP calls and can forward or reject calls depending on whether the security criteria are met.
This also enables secure web conferences without a browser plug-in. In addition, the SBC monitors VoIP traffic, thereby protecting against attacks. This allows tap-proof telephone calls and conference calls via VoIP between different organizations and within different locations of the same organization.

BSI certified and Mitel compatible
Secure connection in times of crisis


The secunet SBC Performance plans are ideal for medium to large infrastructures, with optional high availability and geo-redundancy. The plans can be scaled as needed—even retrospectively. Depending on the plan, between 25 and up to 1,000 calls can take place simultaneously.
The Entry plans enable IP telephony for small infrastructures. Depending on the plan, 10 to 60 calls can be made simultaneously.

The secunet SBC administration interface allows you to configure settings with a high degree of granularity. A central interface also allows you to remotely administer and configure multiple SBCs.
Detailed session monitoring also offers numerous options for scanning the network for errors and inconsistencies.

With the audio conference server, we offer an integrated solution for your audio conferences.
Would you also like to participate securely in video conferences using your web browser? The WebRTC gateway enables secure access to your protected video infrastructure. This means that participants from the internet can be integrated into the existing SIP infrastructure without hesitation.

The secunet SBC ensures optimal data protection with the Zero Trust Monitor. This means that the collected data is pseudonymized before it is stored in the session border controller monitor.
