• Certified Cloud Security Professional (CCSP) for those working in cloud environments 
• Certified in Governance Risk and Compliance (CGRC) exam those in governance and security risk management 
• CompTIA CASP+ for advanced technical professionals like security architects and security engineers 

Also, some security professionals choose to specialize in specific, popular vendors like Amazon Web Services (AWS), Microsoft Azure and Cisco. These show in-depth knowledge of the most in-demand platforms and technologies and offer even more room for specialization, such as the AWS Certified Solutions Architect – Professional certification or the Azure Fundamentals Microsoft certification. 

Other certification bodies like the Information Systems Audit and Control Association (ISACA) and the International Association of Privacy Professionals (IAPP) offer more opportunities for furthering your networking and professional skills.
