Secure video conferencing with OpenTalk: Technical measures for administrators

Video conferencing is now an indispensable tool for internal coordination, collaboration with external partners and communication with colleagues. However, as this technology becomes increasingly important, so too do the security requirements. Administrators have a special responsibility here: they must ensure that video conferencing systems not only function reliably, but are also protected against external threats.

OpenTalk, the European video conferencing solution, offers a customisable, scalable and secure platform that is specifically tailored to the needs of public authorities and businesses. This article shows how administrators can use OpenTalk to ensure the security of video conferences.

1. Modern encryption for secure communication

OpenTalk uses modern encryption standards to ensure the confidentiality of audio, video and chat content. The use of established protocols such as TLS for signal transmission and SRTP for media streams ensures that all data is transmitted securely.

Advantages of OpenTalk:

• Hosting in Germany: All data is hosted on secure German servers or on-premises, guaranteeing digital sovereignty and data protection.
• No external control: On-premises, OpenTalk offers full control over the infrastructure.

2. Robust authentication and access control

Unauthorised access to video conferences can pose significant risks. OpenTalk provides administrators with effective authentication and access control mechanisms to prevent such scenarios, which can be activated by administrators.

Measures in OpenTalk:

• Multi-factor authentication (MFA): Enforce MFA for all users to increase account security.
• Individual meeting access: Avoid recurring meeting links by using unique IDs and passwords for each session.
• Queuing function: Participants are first directed to a waiting room to verify their authorisation before joining the meeting.

3. Network security

OpenTalk enables secure integration into existing IT infrastructures. Admins can seamlessly integrate the platform into their networks, further increasing communication security.

Technical recommendations:

• VPN support: OpenTalk can also be operated in isolated networks and works reliably behind virtual private networks (VPNs), even without direct internet access. This makes the solution suitable for particularly sensitive use cases, such as those tested in security-critical organisations.
• DDoS protection: OpenTalk has integrated rate limits, providing software-based protection mechanisms against distributed denial-of-service attacks to ensure service availability.

4. Scalability and performance

OpenTalk was developed from the ground up for high scalability. The platform uses a modern architecture based on Rust, a programming language known for its security, speed and parallelism. This allows a very high number of users and conference rooms to be supported simultaneously without compromising performance.

Technical highlights:

• Containerisation: Each conference runs in its own container, ensuring clear data separation, trouble-free operation and efficient resource management.
• Kubernetes integration: OpenTalk integrates seamlessly with Kubernetes clusters to enable horizontal scaling.
• Efficient resource management: By using RabbitMQ for signalling, reliable performance is delivered even under high load.

5. Data protection and compliance

OpenTalk meets the strict requirements of the GDPR and offers public authorities and companies a secure, compliant alternative to cloud-based solutions.

Important aspects:

• On-premises option: OpenTalk can be operated directly in your own IT infrastructure, which is ideal for public authorities and critical infrastructure.
• Transparent data processing: Clear guidelines for logging, storing and deleting data.
• Certifications: OpenTalk complies with modern security standards and helps administrators meet compliance requirements.

6. Flexible integration and customisation

OpenTalk is not only secure, but also highly customisable. The platform offers extensive API interfaces that enable seamless integration into existing systems.

7. Training and support

OpenTalk not only offers technical solutions, but also comprehensive support for administrators. Regular training and a personal contact person ensure that users can work safely and effectively with the platform.

Conclusion

OpenTalk is the ideal video conferencing solution for public authorities and companies that value security, scalability and compliance. With modern encryption, robust authentication, flexible integration and European hosting, OpenTalk provides administrators with all the tools they need to ensure secure and efficient video conferencing. At the same time, the platform can be seamlessly adapted to individual requirements – for future-proof communication.

With OpenTalk, administrators can rely on a secure, scalable and sovereign video conferencing solution that meets the requirements of modern organisations.
