# Quality and Testing

### Quality and Testing

emSigner follows a structured and disciplined approach to quality and testing to ensure reliability, security, and consistent performance across its SaaS platform and distributed integration ecosystem. Quality practices are embedded throughout the product lifecycle, from design and development to deployment and post-release monitoring.

***

#### Secure and Quality-Driven Development

emSigner follows an **internal Secure Software Development Lifecycle (Secure SDLC)**, where quality and security considerations are integrated at every stage of product development. This approach helps identify and address functional, performance, and security risks early in the lifecycle.

Development and testing activities are aligned with industry best practices and relevant compliance frameworks such as **ISO 27001** and **SOC 2**.

#### Testing Practices

To ensure stability and correctness of core signing workflows and integrations, emSigner performs multiple levels of testing, including:

* **Unit Testing**\
  Individual components and services are validated to ensure correct behavior.
* **System and Functional Testing**\
  End-to-end testing of core product features such as document signing, workflows, notifications, and integrations.
* **Regression Testing**\
  Existing functionality is revalidated during every planned release to prevent unintended impact from new changes.
* **Performance and Load Testing**\
  The platform is tested to handle expected transaction volumes, concurrent users, and peak usage scenarios.
* **Security Testing (VAPT)**\
  Regular vulnerability assessments and penetration testing are conducted to identify and remediate security weaknesses.

***

#### Third-Party Security Testing

In addition to internal testing, emSigner undergoes **third-party security and penetration testing**. These assessments provide independent validation of the platform’s security posture and help ensure alignment with industry security standards.

***

#### Release and Change Management

emSigner follows **planned release cycles** to ensure controlled and predictable delivery of product updates. Each release undergoes defined quality checks before deployment.

Changes are carefully reviewed to maintain platform stability, especially in environments with customer-specific configurations or private deployments.

***

#### Post-Release Monitoring and Improvements

After release, the platform is continuously monitored to identify potential issues in real-world usage. This includes:

* Monitoring system behavior and performance
* Addressing reported issues through hotfixes where required
* Continuous improvement based on operational insights and customer feedback

#### Continuous Improvement

Quality and testing practices at emSigner are continuously reviewed and enhanced to keep pace with evolving security threats, regulatory expectations, and customer needs. This ensures the platform remains dependable, secure, and scalable as usage grows.
