# Secure code from the first commit.

> Secure development means building security into every phase of software and firmware development: requirements, design, coding, testing and maintenance. Zyberum provides secure coding training for development teams, manual source code review supported by SAST, threat modelling, and secure SDLC and DevSecOps implementation aligned with the Cyber Resilience Act, ISO/SAE 21434 and IEC 62443-4-1.

Secure coding training, source code review, threat modelling and DevSecOps. Build secure software and firmware and meet CRA and ISO/SAE 21434 requirements.

Most vulnerabilities are written, not deployed. We help your developers avoid them with secure coding training, expert code review, threat modelling and a secure development lifecycle that fits your tools and pace.

## Secure development services

### Secure coding training

Hands-on workshops for developers: common vulnerability classes, secure C/C++ for embedded systems, web and API security, with exercises on real code.

### Source code review

Manual review by experienced security researchers, backed by SAST tooling. A thorough review can eliminate up to 90% of future vulnerabilities.

### Threat modelling

Identify threats and security requirements early, in design workshops with your architects (STRIDE, attack trees, TARA).

### Secure SDLC & DevSecOps

Security gates, SAST and SCA, secrets scanning and SBOM generation integrated into your CI/CD pipeline.

### Security requirements

Testable security requirements derived from threats, regulations and standards, traced through to verification.

### Process gap analysis

Your development process assessed against the CRA, ISO/SAE 21434 or IEC 62443-4-1, with a prioritised roadmap.

## Cheaper to prevent than to patch

A vulnerability found in code review costs a fraction of one found after release, especially in firmware for devices and vehicles that are hard to update.

Regulation now demands it: the Cyber Resilience Act, ISO/SAE 21434 and IEC 62443-4-1 all require a documented secure development process and evidence that it is followed.

- Fewer vulnerabilities reach production
- Faster and cheaper remediation
- Audit-ready evidence for CRA, ISO/SAE 21434 and IEC 62443
- Developers who think like attackers

## FAQ

**What is secure coding?**

Secure coding is the practice of writing software that avoids common vulnerability classes such as buffer overflows, injection flaws and broken authentication. It combines developer knowledge, coding guidelines such as SEI CERT C, MISRA or OWASP, and tool support.

**What is the difference between a code review and a penetration test?**

A code review analyses the source code directly and finds root causes, including issues that are hard to reach from outside. A penetration test attacks the running system like a real attacker would. They complement each other; for critical products we recommend both.

**Can the training be tailored to our code base?**

Yes. In-house workshops use examples from your technology stack and, on request, anonymised findings from your own code.
