How hospital can secure medical devices and building automation against cyberattacks

The situation of OT cybersecurity remains challenging in 2025. Although only a few attacks - compared to the total number of cyberattacks - targeted industrial facilities directly in 2024, the attack surface continues to evolve.

In our blog post “How useful is AI in OT security monitoring?” we examined the added value and risks of artificial intelligence in OT security solutions. Time to put the some common arguments for AI to the test.

Artificial intelligence seems to be seen as a panacea these days – from tomorrow’s shopping list to world peace.

Artificial intelligence (AI) is currently hailed as a silver bullet against almost everything. So it's no wonder that OT security is also expected to benefit from a self-learning system. Together with Rhebo and other technology partners, the Fraunhofer IOSB has investigated the possibilities in the AICAS project. The automation of AI-triggered mitigation mechanisms is not (yet) recommended in OT.
