In this episode, host Etienne Nichols sits down with Jose Bohorquez and Mohamad Foustok from CyberMed to dissect the complex world of Software as a Medical Device (SaMD) and cybersecurity. They emphasize that SaMD is first and foremost a medical device and should be treated as such from the very beginning of the development process. The conversation highlights the most common mistakes companies make, like treating security as an afterthought and jumping straight into coding without a solid architectural plan.

Mohamad Foustok introduces the concept of "zero trust" and the critical importance of designing for security across the entire product lifecycle, from initial concept to post-market surveillance. The discussion clarifies that cybersecurity is not limited to network-connected devices but applies to any medical device with a software function, regardless of its connectivity. They also touch on the historical context of FDA guidance, noting a significant shift in recent years that has raised the regulatory bar and put a greater emphasis on robust cybersecurity documentation.

The guests provide actionable advice for MedTech professionals, stressing the value of a balanced approach that integrates security and functionality from day one. They explain that a well-thought-out process, though seemingly slower at the outset, ultimately saves time and resources by preventing costly and time-consuming redesigns later on. This episode serves as a vital guide for anyone looking to build a secure and compliant medical device in today's evolving regulatory landscape.

Quotes

"Software as a medical device ultimately is a medical device, and so you want to be developing it from the get-go with that mindset." — Jose Bohorquez

"Security can't be an afterthought. You have to consider security at the inception of your approach to a product." — Mohamed Fustok

Takeaways

A "Security-First" Mindset is Essential: Integrate cybersecurity from the initial architectural phase of your project. This proactive approach saves significant time and money by avoiding costly redesigns and delays later in the development process or after an FDA submission.
Cybersecurity is for All Software-Driven Devices: Don't assume that only cloud-connected devices need cybersecurity documentation. The FDA requires documentation for any device with a software function, including embedded systems and programmable logic, even if it's not connected to a network.
Regulatory Compliance is a Process, Not a Document: The FDA is not just looking for a checklist of documents; they want to see a well-defined and consistently followed process for how you build and secure your software. This includes a "reasonable assurance of cybersecurity" that stands up to scrutiny.
Hospitals are Your New Regulators: Beyond FDA compliance, be prepared for hospitals and other buyers to conduct their own rigorous cybersecurity audits. A strong cybersecurity posture is becoming a key differentiator and a prerequisite for market access.

MedTech 101

Zero Trust: A cybersecurity principle that means you should never automatically trust anything inside or outside of your network perimeter. Instead, every access request must be verified before granting access. Think of it like a strict security guard who checks everyone's ID, even if they claim to work there. In a hospital setting, this means a medical device should not assume the hospital's Wi-Fi is secure; it should treat every connection as potentially hostile and build in its own protections. This is in contrast to the old model where everything inside the network was trusted by default.
