Security & Tracking
As EV adoption accelerates, charging infrastructure is becoming a critical part of modern energy systems. With this development comes a clear requirement for robust cyber security.
“In a world where every charge point is also a connection point, the strength of our energy future will be defined not just by how we generate power, but by how well we protect it”, says Ole Christian Tvedt, CIO of DEFA Group.
EV chargers are no longer standalone devices. They are connected systems that communicate with vehicles, cloud platforms, payment solutions, and energy management systems.
This connectivity makes cyber security essential to:
- protect user data and privacy
- prevent unauthorized access and control
- ensure system integrity and uptime
- safeguard energy infrastructure
Without sufficient protection, charging infrastructure can become a point of vulnerability in larger networks.
Built for compliance
DEFA Power is developed to comply with key international standards and regulations. It is designed to deliver secure, compliant, and reliable charging, giving operators and users full confidence in connected environments.
Radio Equipment Directive (RED)
Compliance with RED ensures that DEFA Power meets EU requirements for safety, electromagnetic compatibility, and efficient use of the radio spectrum. It also includes cyber security requirements that help protect against fraud, data breaches, and misuse.
Ole Christian Tvedt:
“RED is an important step toward creating a secure and reliable charging infrastructure across Europe. By combining technical safety with clear cyber security requirements, the directive helps build trust among both users and stakeholders in the energy system.”
Open Charge Point Protocol (OCPP)
OCPP 2.0 enabling secure communication between charging stations and backend systems. This ensures interoperability and reliable data exchange across platforms.
“By supporting OCPP 2.0, DEFA Power ensures open, secure, and future-proof communication between charging infrastructure and backend systems—giving our customers the flexibility to integrate, scale, and operate with confidence”, says Tvedt.
Secure communication
Data exchange between the charger and backend systems is protected using established industry protocols, reducing the risk of interception or manipulation.
Authentication and access control
Access is restricted through defined authentication mechanisms, ensuring that only authorized users and systems can interact with the charger.
Regular software updates
DEFA Power supports secure firmware updates, enabling efficient handling of vulnerabilities as requirements evolve.
Data protection
User and operational data are handled according to best practices for privacy and secure storage.
Future-ready charging infrastructure
Cyber security requirements evolve continuously. DEFA Power is built with scalability and adaptability in mind, aligned with evolving standards and regulatory frameworks.
This ensures long-term resilience for charging networks.
A trusted solution for a connected world
Ole Christian Tvedt:
“DEFA Power is a secure, compliant, and future-ready charging solution. It is designed to deliver reliable performance and advanced features across residential, commercial, and public use cases, while maintaining control and trust in an increasingly connected energy ecosystem.”
Key security and technology strengths include:
- A secure boot process that ensures attackers cannot run unsigned or unauthorized software on DEFA Power.
- Tamper-proof transaction data with cryptographically signed measurements, enabling trusted validation by operators and end users.
- Fully local load balancing logic, reducing dependency on cloud connectivity and helping prevent denial-of-service attacks against critical charging infrastructure.
Together, these capabilities reinforce DEFA Power’s position as a trusted, intelligent, and future-ready charging platform for the next generation of EV infrastructure.
