In a DevSecOps environment, several types of security professionals are typically involved to ensure a comprehensive approach to security. These may include:

• Security Engineers/Analysts: They focus on designing, implementing, and maintaining security measures within the DevSecOps pipeline.
• Application Security Specialists: These experts concentrate on securing applications, identifying vulnerabilities, and ensuring secure coding practices.
• Penetration Testers (Ethical Hackers): They conduct controlled attacks on systems to identify vulnerabilities and weaknesses in applications and infrastructure.
• Security Architects: They design and implement security systems, including the selection of appropriate tools, technologies, and processes.
• Compliance and Risk Management Experts: They ensure that security practices align with industry regulations, standards, and internal policies.
• Security Automation Engineers: They focus on automating security tasks, integrating security tools into the DevOps pipeline, and enabling continuous security testing.
• Security Auditors and Compliance Officers: They evaluate processes and systems to ensure they meet regulatory and compliance requirements.
• Security Incident Response Team (SIRT): They handle security incidents, conduct investigations, and coordinate responses to security breaches or incidents.
• Security Awareness and Training Specialists: They educate development and operations teams about security best practices and promote a security-conscious culture.
• DevSecOps Evangelists/Advocates: These are individuals who promote security awareness and advocate for security practices within the DevOps and development teams.

Remember that the specific roles and titles may vary depending on the organization's size, structure, and industry. It's crucial for these professionals to work collaboratively with developers, operations, and other stakeholders to integrate security seamlessly into the development process.
