Cybersecurity in Product Development

Cybersecurity Is Now a Core Part of Product Development

Cybersecurity is no longer an IT concern handled after the fact. It is being driven directly into product development by regulation, standards, and real‑world incidents.

Frameworks and regulations such as NIS2 and the EU Cyber Resilience Act (CRA), together with standards like ISO/SAE 21434, IEC 62443, and IEC 81001‑5‑1, all point in the same direction: cybersecurity must be built into the product lifecycle, not bolted on later. Responsibility is clearly shifting toward manufacturers and product developers.

Almost every product today contains software, connectivity, remote access, or update mechanisms. That means cybersecurity decisions are made continuously during system architecture, software design, hardware partitioning, and supplier integration, whether they are recognized as such or not.

If cybersecurity is treated as a late compliance task, the result is architectural rework, certification friction, safety concerns, and long‑term inefficiency.

We help organizations embed cybersecurity directly into system, software, and hardware development in a way that supports safety, compliance, and productivity.

Cybersecurity Is a Design Constraint, Not an Add‑On

Modern products operate in environments they do not fully control. They interact with users, other systems, cloud services, suppliers, and field tools throughout their lifetime.
This makes cybersecurity a design constraint that influences:

• System partitioning and trust boundaries
• Interface definitions and assumptions
• Update, diagnostics, and maintenance concepts
• Supplier responsibilities and integration models

Addressing cybersecurity early is not about adding overhead. It is about protecting architectural choices, avoiding late rework, and maintaining control over system behavior across the lifecycle.

Cybersecurity and Functional Safety Are Tightly Linked

In cyber‑physical systems, cybersecurity is not just about data protection. Security failures can become safety hazards.

Examples seen in real systems include:

• Compromised communication paths that disable safety functions
• Unauthorized software modifications that change control behavior
• Loss of system integrity that invalidates safety assumptions
• Denial‑of‑service scenarios that prevent monitoring or safe shutdown
• Loss of control in remote controlled ora automated systems

This is why modern standards increasingly connect cybersecurity risk management with functional safety. A safety concept that ignores cybersecurity assumptions is often incomplete.

We treat cybersecurity and functional safety as one coherent system engineering problem, addressed together through architecture, requirements, risk analysis, and verification.

Cybersecurity Is Defined by Process Standards — Not Product Feature Checklists

A common misconception is that cybersecurity is mainly about fulfilling a fixed set of product‑level requirements.

In reality, most cybersecurity standards do not prescribe specific security features that every product must implement. Instead, they define how product development must be performed: how risks are identified, how decisions are justified, how evidence is created, and how security is maintained throughout the lifecycle.

This means cybersecurity is primarily a process discipline, not a one‑time technical checklist.
In practice, cybersecurity standards require organizations to:

• Identify and assess cybersecurity risks systematically
• Derive security requirements from risk, context, and intended use
• Make architectural and design decisions explicit and reviewable
• Manage assumptions, interfaces, and trust boundaries
• Maintain traceability from risks to requirements, design, and verification
• Handle changes, updates, and vulnerabilities over the product lifetime

The concrete security mechanisms used in a product are context‑dependent outcomes of this process — not predefined obligations.

This is why cybersecurity cannot be “added” late, nor solved by a single team. It must be integrated into day‑to‑day development work, using processes and tooling that engineers actually use.

What We Do — and What We Don’t

We are not an IT security consultancy, a penetration‑testing vendor, or a compliance documentation factory.
We work inside product development, focusing on:

• Embedding cybersecurity into system, software, and hardware engineering
• Aligning cybersecurity with functional safety
• Translating standards into practical, usable development processes
• Enabling traceability, evidence, and audit readiness
• Supporting long‑term, multi‑year product lifecycles

Our work is grounded in systems engineering, not checklists.

Processes, Tooling, and Evidence That Scale

In regulated product development, the primary objective is not compliance, but sustainable productivity — the ability to develop, change, and verify products efficiently over time.

This productivity is determined by the tight interplay of processes and tooling. When governance, workflows, and tools are aligned, cybersecurity activities become a natural part of everyday engineering work rather than separate compliance tasks.

Compliance then emerges as a by‑product: risks are managed, traceability exists, and evidence is available — not because teams optimize for compliance, but because the development system itself works and scales.

Polarion ALM

Polarion ALM ensures full traceability and transparency across all project data, enabling clear tracking of changes and seamless requirements management for enhanced compliance and collaboration.

Relevant Across Industries

Cybersecurity is now a baseline expectation across regulated industries, even though the drivers and emphasis differ.

Automotive
Driven by ISO/SAE 21434, cybersecurity is essential for software‑defined vehicles, lifetime updates, type approval, and liability management.

Machinery & Off‑Highway
IEC 62443 reflects the reality of connected, automated, and remotely serviced machines where cyber incidents can lead to unsafe operation or production downtime.

Aviation
DO‑326A / ED‑202A require cybersecurity to be addressed without compromising deterministic behavior, certification assumptions, or safety cases.

Defense
NIST‑based and NATO‑aligned frameworks make cybersecurity integral to system trust, mission assurance, and safe operation in adversarial environments.

Medical Devices
IEC 81001‑5‑1 highlights that cybersecurity failures can directly affect patient safety and post‑market compliance obligations.

Energy & Infrastructure
IEC 62443 addresses systems where cyber incidents can have large‑scale safety, environmental, and societal consequences.

Marine
IMO cyber risk management guidance and IACS Unified Requirements UR E26 and UR E27 drive cybersecurity into ship and marine system design. Cybersecurity failures can affect navigation, propulsion, and safety‑critical onboard systems, making cybersecurity a core part of marine product development.

Across all of these industries, cybersecurity is no longer optional. And no longer separable from product engineering.
