We help creators of intelligent connected devices to design, implement and operate their systems with a sustainable security level.

We want to help to make it a habit to consider security aspects in any man-made system. Since its definition, on to its design and implementation, and during its operation.

Why choose our
“Security Pattern”?

Because of the combination of skills and know-how of our team. We have proved our capability to:

• Master the basic elements of security: from the definition of cryptographic algorithms (e.g. SHA3), to their HW and SW implementation, under many aspects (performance, protection, etc.);

• Know how to specify secure protocols (e.g. Bluetooth);

• Know how to identify the balanced mix of ingredients that is needed to protect a system and how to make them interact properly;

• Listen to the needs of technical people, managers, marketers, customers; harmonize the various viewpoints and goals; define effective action plans to achieve the shared objectives.

Starting from these facts, our experience has led us to define methodologies to study at design-time, to build and ultimately to assess the security of a system.
Because security is a process and standalone components are not enough.

Security Pattern obtained the Certificate of Conformity to IEC 62443-4-1:2018 in recognition of the alignment of the internal processes to the secure product development requirements mandated by the standard
