Product Cybersecurity Assessment

A Product Cybersecurity Assessment is an expert review of a digital product’s security architecture, attack surface, trust boundaries and operational controls.

The assessment considers the product as a complete system. Depending on the agreed scope, this may include:

• Physical or embedded hardware
• Firmware and operating systems
• Web applications and customer portals
• Mobile applications
• Cloud platforms and remote services
• Application programming interfaces
• Network services and communication protocols
• User, administrator and service accounts
• Software libraries and third-party components
• Update, patching and vulnerability-management processes

Unlike a basic automated vulnerability scan, the assessment evaluates how product components interact, where trust changes between systems and whether security controls are appropriate for the product’s intended use and risk profile.

The service is suitable for organisations that develop, manufacture, supply or operate products with digital elements, including:

• Connected consumer and professional products
• Internet of Things devices
• Embedded systems and controllers
• Industrial automation components
• Smart equipment, sensors and gateways
• Software products and SaaS platforms
• Mobile applications linked to physical products
• Cloud-connected machinery or equipment
• Monitoring, measurement and laboratory systems
• Products containing firmware or remotely updateable software

An assessment can be performed during development, before a major release, before market placement, after significant architecture changes or when an organisation needs stronger cybersecurity evidence for customers and compliance activities.

The exact scope is agreed according to the product, intended use, technical architecture, available evidence and applicable cybersecurity requirements.

These assessment areas reflect widely recognised product-security concerns and are consistent with the methods publicly described for the ComplyMarket Cybersecurity Lab.

1. Define the Product Boundary

The first step is to determine what belongs to the product ecosystem. This includes the product itself and any connected application, API, cloud service, update server or remote-processing function required for its operation.

Clear boundaries prevent important components from being overlooked.

2. Review Architecture and Product Evidence

Available technical information is reviewed to understand how the product works and how security decisions have been made.

Relevant inputs may include:

• Product descriptions and intended-use information
• Architecture and data-flow diagrams
• API documentation
• User and administrator roles
• Firmware or software information
• Update packages and update procedures
• Software Bills of Materials or dependency lists
• Security requirements and test results
• Installation and configuration instructions
• Vulnerability disclosure and incident procedures

3. Map Threats, Trust Boundaries and Attack Surfaces

The assessment identifies important assets, possible threat actors and realistic misuse scenarios. Product interfaces are mapped to determine how an attacker could attempt to reach sensitive data, privileged functions or connected systems.

4. Evaluate Security Controls

Authentication, authorisation, cryptography, secure configuration, logging, updates and other relevant controls are examined against the product’s risks.

Where agreed, selected controls may also be technically validated through targeted security testing.

5. Rate and Prioritise Findings

Findings are assessed according to their likely impact, exploitation conditions, affected components and relevance to the product’s operation.

This helps teams separate urgent security issues from lower-priority improvements.

6. Prepare the Assessment Report

A typical report may contain:

• Assessment scope and product boundary
• Architecture and attack-surface summary
• Identified trust boundaries
• Risk-rated findings
• Affected products or components
• Supporting technical evidence
• Recommended corrective actions
• Remediation priorities
• Compliance observations where applicable
• Management-level summary

ComplyMarket’s published cybersecurity service describes risk-rated reports, attack-surface inventories, threat-model summaries, remediation roadmaps and retesting as possible project outputs.

Define Security Requirements Early

Document security objectives during product planning. Requirements should address the complete ecosystem, including devices, software, applications, cloud functions and external interfaces.

Maintain Current Architecture and Data-Flow Diagrams

Security assessments become less reliable when architecture documentation no longer reflects the actual product. Diagrams should show where data is collected, stored, processed and transmitted.

Remove Unnecessary Exposure

Disable unused ports, services, protocols, test accounts and debugging functions. Every unnecessary interface can increase the product’s attack surface.

Separate Authentication from Authorisation

Confirming a user’s identity does not automatically mean that the user should have access to every function. Permissions should follow clearly defined roles and the principle of least privilege.

Protect Credentials and Cryptographic Material

Passwords, API keys, certificates and private keys should not be hardcoded or stored without suitable protection. Key generation, distribution, rotation and revocation should be governed throughout the product lifecycle.

Use Secure Default Settings

Products should not rely on users to correct insecure configurations after installation. Default accounts, passwords, network services and permissions should be reviewed before release.

Secure the Update Process

Products should verify the source and integrity of updates before installation. Update mechanisms should also consider interrupted installations, unauthorised downgrade attempts and recovery from failed updates. OWASP’s IoT testing guidance specifically addresses verification and protection of firmware update mechanisms.

Record Meaningful Security Events

Logs should support investigation without exposing passwords, tokens, personal information or other sensitive data. Organisations should define which events are recorded, how long they are retained and who can access them.

Monitor Third-Party Components

Open-source and commercial dependencies should be inventoried and reviewed throughout the support period. New vulnerabilities can affect a product even when its own source code has not changed.

Retest Important Corrections

Critical or high-risk findings should be retested after remediation. A written correction does not confirm that the issue has been resolved effectively or that the change has not introduced another weakness.

Supporting Product Cybersecurity Compliance

Product cybersecurity is increasingly connected to product compliance, technical documentation and lifecycle responsibilities.

The EU Cyber Resilience Act establishes cybersecurity requirements for many products with digital elements, including requirements concerning secure design, vulnerability handling and product support. The regulation covers both technical product requirements and the processes manufacturers use to manage vulnerabilities after products are placed on the market.

Depending on the product and compliance objective, an assessment may be mapped against relevant requirements or recognised references such as:

• EU Cyber Resilience Act requirements
• IEC 62443 for industrial automation and control products
• OWASP application, API, mobile and IoT guidance
• NIST secure software development guidance
• Vulnerability disclosure and handling practices
• Secure configuration benchmarks
• Software Bill of Materials formats and component records

Framework selection should always be based on the product type, sector, target market and agreed assessment purpose. A product cybersecurity assessment supports readiness and evidence development, but it does not automatically constitute formal certification or regulatory approval.

Is a Product Cybersecurity Assessment the Same as Penetration Testing?

No. Penetration testing attempts to identify exploitable technical vulnerabilities within an authorised scope. A Product Cybersecurity Assessment is broader and can include architecture, trust boundaries, development practices, update processes, logging, vulnerability management and compliance evidence.

Penetration testing may be included as one part of a wider assessment where appropriate.

When Should a Product Be Assessed?

Assessment is most valuable before market release, following major product changes, when new connectivity is introduced or when cybersecurity documentation must be strengthened. Periodic reassessment may also be necessary because dependencies, threats and known vulnerabilities change over time.

What Information Is Needed to Begin?

Useful information normally includes a product description, intended use, architecture diagrams, data flows, account roles, interface documentation, update information and available security records. The final evidence request depends on the agreed product scope.

Can the Assessment Support Cyber Resilience Act Readiness?

Yes. Where the Cyber Resilience Act is relevant, assessment findings can help identify gaps involving product security controls, attack-surface reduction, secure updates, vulnerability handling, logging and technical evidence.

Formal conformity assessment or certification, where legally required, must be performed by an appropriately authorised body.

ComplyMarket combines cybersecurity assessment, product-compliance knowledge and technical-documentation support to help organisations move from security uncertainty to a practical improvement plan.

Depending on the agreed scope, ComplyMarket can support your organisation with:

• Product architecture and attack-surface reviews
• Trust-boundary and data-flow analysis
• Authentication and authorisation assessments
• Cryptography and secure-configuration reviews
• Software-update and rollback-protection reviews
