About Us

Product security is a craft. We built a guild around it.

Product Security Guild is a team of senior practitioners who secure regulated and safety-critical products. Leadership, engineering, testing, regulatory evidence, and lifecycle support come from one group, not from a chain of handoffs between vendors.

Why “The Guild”

The name is the operating model.

A guild is a body of practitioners who hold a standard, train the next people into it, and are proud of the work that carries their mark.

A specialized craft

Product security is its own discipline, not a task bolted onto an engineering or IT role. It is learned by doing it repeatedly, on real products, under real review.

Multiple disciplines, one team

A connected product needs embedded, software, cloud, regulatory, and risk expertise working the same problem at the same time, not queued behind each other.

Our mission

Make safety-critical products more secure, resilient, and trustworthy by helping organizations turn complex cybersecurity risks, regulatory expectations, and technical challenges into practical engineering solutions throughout the total product lifecycle.

How we work

Our Five Truths

01

Practical and defensible security

Every control, document, and test result should survive one question: why is this adequate? If it cannot answer that for a regulator, a customer, or a court, it is decoration.

02

Technical quality and professional judgment

Findings get assessed, not counted. A severity rating that ignores how the product is actually deployed and used is noise, and it costs you the budget you needed for the real issue.

03

Clear communication and transparency

Plain explanations of what we found, what it means for the product, what it costs to fix, and where we are not certain. Uncertainty stated up front is cheaper than uncertainty discovered later.

04

Collaboration across disciplines

Security decisions land on architecture, safety, quality, and regulatory. We work with those teams rather than around them, because a control that the product team will not maintain is not a control.

05

Security throughout the product lifecycle

Premarket evidence is the opening, not the finish. Products stay in the field for years, and the vulnerability, disclosure, and support obligations follow them the whole way.
