About Rida

Cybersecurity and digital transformation expert, I leverage over a decade of experience to secure and strengthen the resilience of your information systems. My goal: to make your digital environment a fortress, capable of anticipating and countering cyber threats while supporting your business ambitions.

With in-depth expertise in risk management, I excel in applying ISO 27005 and EBIOS Risk Manager methodologies to identify, prioritize, and address vulnerabilities. My tailor-made strategies, perfectly aligned with regulatory requirements (GDPR, NIS2), protect your critical assets and ensure business continuity.

Specializing in offensive security, I conduct advanced penetration tests on web applications, APIs, mobile environments, and cloud infrastructures. By rigorously exploiting the OWASP Top 10 and CWE/SANS Top 25 frameworks, and by developing custom tools in Python, Bash, and PowerShell, I automate vulnerability analysis to ensure optimal responsiveness to attacks.

As a natural leader, I manage cross-functional projects by integrating best DevSecOps practices into your CI/CD pipelines. My ability to simplify complex technical concepts and train your teams fosters a sustainable and collaborative security culture, essential in an ever-evolving digital landscape.

Always staying updated on emerging threats – including those related to artificial intelligence – I propose innovative solutions to anticipate tomorrow's risks. Together, we will build a robust and agile digital infrastructure, ready to meet the challenges of the cyber-revolution.

Your security is my priority: let's turn your digital challenges into a strategic and lasting success.
