serve as a foundational component of OT, providing the essential control infrastructure that enables safe, stable, and efficient opera- tion of continuous industrial processes. “Digitalization initiatives have pushed
DCS towards higher levels of connectivity and automation,” says Veltheim. “Today, DCS are expected to provide open and secure connectivity at all levels, including between operational and information systems.” However, this shift introduces a new
layer of complexity: securing the convergence point where data from physical operations intersects with enterprise IT systems. This is where modern distributed control systems play a pivotal role.
Cybersecure by Design To meet these challenges,
Valmet has launched the newest generation of its DNA distrib- uted control system from the very first lines of code to deliver cutting edge cybersecurity, user interface, data storage and man- agement, and other advanced features
Introduced in 2024, Valmet
DNAe takes a modern and proactive approach to cybersecu- rity, enabling companies to effectively prevent and respond to evolving cyber threats. Valmet DNAe was built
with IT/OT convergence in mind, offering seamless connec- tivity from sensors to the cloud via edge technology and indus- trial-standard interfaces. The integration enables enhanced digital intelligence, paving the way for AI-powered tools at every level. According to David Ding,
OT cybersecurity engineer, Valmet, “DNAe is engineered with security at its foundation, empowering customers to stay ahead of cyber threats as OT environments become more interconnected and complex.” Valmet approached the task
by adopting the cybersecurity philosophy known as “security by design.” This school of thought emphasizes incorporat- ing security measures from the very beginning of a product’s development cycle, rather than adding them later in response to threats.
Valmet recently reached a
significant milestone in indus- trial cybersecurity by becoming the first fully web-based system to receive the ISASecure System Security Assurance (SSA) Security Level 1 certificate. The external assessment conducted by exida, a product certification and knowledge company special- izing in automation system safe- ty, alarm management, cyberse- curity, and availability, ensured that Valmet DNAe meets the strict security requirements and levels specified in the ISA/IEC 62443-3-3 standard. At the core of the Valmet DNAe Distributed Control
System is the Trusted Information Framework (TIF), which serves as the back- bone for communication and data manage- ment. Built upon the TIF foundation, Valmet DNAe architecture includes measures such as role-based access control, authentication, encryption, endpoint protection and compre- hensive audit trails. Valmet DNAe incorporates endpoint
protection measures such as system harden- ing, antivirus software and application whitelisting to reduce the risk of malware, unauthorized access and system compromise. Encryption protocols, access controls,
and VPN tunneling are used to secure data transmissions by encrypting communications

and restricting access to authorized users, protecting sensitive information from inter- ception or tampering. These measures sup- port secure remote access, enabling approved personnel to monitor, operate, and maintain mill systems from any location while preserv- ing the confidentiality and integrity of all communications. For IT teams, Valmet DNAe provides
centralized user management and Active Directory (AD) integration, enabling role- based access control and authentication. The system offers authorization, audit trails, secure communication, encryption mecha- nisms, content-signed software, and compre-
