About
About Hellebore Security
A cybersecurity firm specialising in proactive security, offensive security research and the advanced protection of critical infrastructure. Founded in early 2023 by Morgana Arreni and headquartered in Rome, Italy.
Hellebore Security was founded to respond to the growing and increasingly complex digital threats facing high-risk sectors, where cyber resilience is a fundamental operational requirement.
By combining a rigorous methodological approach with a deep understanding of threat intelligence, we help complex organisations and industrial ecosystems identify and mitigate structural vulnerabilities before malicious actors can exploit them.
Our core expertise ranges from application security to complex network architectures. Our specialist focus is offensive security for medical devices and the Internet of Things (IoT): sectors where protecting data and the integrity of systems directly affects the continuity of essential services.
The hellebore is a winter flower: it blooms when everything else is dormant, and every part of it is poisonous. It felt like the right name for a firm that stays alert when others are not, and that thinks like an attacker.
What we stand for
Integrity
We report what we find, including when we find little. We never inflate severity to justify effort.
Curiosity
We take the time to understand how your systems really work, because that's where the interesting flaws hide.
Care
Your systems, data and people deserve to be handled carefully. Safety and confidentiality come before speed.
Let's talk about what you need to protect.
Tell us a little about your environment and goals. We'll reply with questions, a suggested scope, or an honest note if we're not the right fit.
