Cognitive Security

With the rapid development of digital innovation, we are moving toward an era of interconnection and automation with the focus on technologies such as the Internet of Things, big data, machine learning, etc. Corporations, organizations and people are revolutionizing production, processes and work environments. Trends like Industry 4.0, artificial intelligence and IoT offer enormous benefits for efficiency and connectivity, but they also impose bigger challenges on cybersecurity.

Data volume and complexity are currently scaling up incredibly fast. Security engineers are overwhelmed by the need to handle an exponentially rising number of cyber threats, and it is becoming much easier for attackers to carry out malicious actions on their targets using a vast number of publicly available hacking tools. It is therefore essential to develop innovative security technologies that can help us better understand potential threats and malicious behavior, and to provide more secure and robust protection mechanisms.


Fraunhofer AISEC develops innovative technologies for cognitive security, in which we leverage cutting-edge machine learning algorithms to enhance current IT systems with regard to both software and hardware security. Using techniques like machine learning and deep neural networks, these cybersecurity systems can be enhanced to dynamically adapt to environmental changes. Security engineers can also enhance their ability to handle large-scale and high-complexity cyberattacks. We design and develop cognitive security solutions for the prediction, understanding and deduction of malicious activities, and we provide protection mechanisms as well as best practice. We also collaborate with other security technology teams to provide customisied solutions matching specific customer requirements.
