NIS2 Compliance: How TrueConf Server Keeps Your Communications Secure

The directive draws a clear line between two types of organizations:

Essential entities: large organizations in sectors like energy, transport, banking, healthcare, digital infrastructure, and public administration. These face the most rigorous supervision and mandatory incident reporting requirements.

Important entities: mid-sized organizations spread across a broader range of sectors. Oversight is somewhat lighter, but the underlying security obligations are largely the same.

What NIS2 actually requires organizations to do:

• Maintain risk analysis and information security policies
• Handle and report incidents within defined timeframes
• Plan for business continuity and crisis scenarios
• Assess supply chain security
• Ensure secure acquisition, development, and maintenance of systems
• Run cybersecurity training and awareness programs
• Apply cryptography and encryption where appropriate
• Enforce access controls and manage assets properly
• Implement multi-factor authentication (MFA) across secure communications

Why Your Communication Stack Is a Compliance Risk?

Here’s something that often gets overlooked: NIS2 risk-management obligations apply to the network and information systems organizations use to store, process, and transmit data, including communication tools that carry sensitive organizational information.

These systems touch strategic decisions, client communications, and internal data that organizations genuinely cannot afford to expose.

Where standard communication tools tend to fall short:

• Unauthorized access to live meetings or archived message histories
• Video, audio, and file transfers sent without encryption in transit
• Data sovereignty gaps when content is processed or stored by non-EU cloud providers
• Weak access controls that let unauthorized participants into calls or file repositories
• Absent audit trails that make incident investigation, and NIS2 reporting, practically impossible
• Uncontrolled third-party integrations that quietly expand your attack surface

How TrueConf Server Addresses NIS2 Requirements?

TrueConf Server is a self-hosted unified communications platform that organizations deploy on their own infrastructure, whether that’s on-site servers, a private cloud environment, or a fully air-gapped network. The organization controls the deployment environment, security configuration, data flows, and integration choices, which can make the communications layer easier to align with internal security and compliance policies.

Data Sovereignty

In an on-premises or isolated deployment, video conferences, chats, files, and recordings can remain within the organization’s own infrastructure. This reduces reliance on third-party cloud processing and supports NIS2 supply-chain risk management, although external integrations, federation, streaming, SMTP, and push-notification flows should still be reviewed as part of the organization’s security assessment.

Encryption

TrueConf Server protects communications traffic with encryption mechanisms built into its architecture:

• TLS-based protection for signaling and control data
• AES-256 for media traffic in the TrueConf protocol
• DTLS/SRTP for WebRTC media paths
• H.235 for H.323 scenarios

These protections are part of the platform’s communications architecture. For stored recordings, chat files, and other data at rest, organizations should also apply appropriate infrastructure-level controls, such as disk or partition encryption, retention policies, and access restrictions.

Access Control and Multi-Factor Authentication

• Integration with Active Directory and LDAP for centralized enterprise identity management
• Role-based access controls applied consistently across all platform functions
• MFA support for all users, directly aligned with NIS2’s explicit MFA requirement
• Administrator-defined permissions governing who can schedule meetings, access recordings, share files, and manage the system

Audit Logging

TrueConf Server provides reports and logs covering user connections, calls, messages, conference recordings, server events, and settings-change history:

• Ongoing internal security monitoring
• Meeting NIS2’s incident reporting obligations
• Providing the evidentiary record needed for post-incident forensic reconstruction

Isolated and Air-Gapped Deployment

TrueConf Server can operate in completely isolated environments with zero internet connectivity. For organizations in defense, critical infrastructure, government, and other high-assurance environments where strict network segregation may be required, this capability is essential rather than optional.

Secure External Collaboration

Guests and external participants can join TrueConf meetings through a browser-based WebRTC client, without installing a dedicated conferencing application or creating accounts on external conferencing platforms. Access is controlled through:

• Guest permissions
• Conference-level access restrictions
• Registration and approval settings
• Administrator-defined policies for external usersl

There’s no dependency on external authentication providers or third-party identity systems.

Business Continuity

TrueConf Server can support business continuity planning by giving organizations control over the deployment environment and operational procedures:

• Backup and restore of server settings
• Real-time and historical server monitoring
• Organization-controlled maintenance windows
• Disaster recovery planning based on the organization’s own infrastructure architecture
