As a Cyber Security Analyst, you could manage the security of the organisation you work for or offer security services and consultancy to other companies. 

An organization employs Internal Cyber Security Analysts directly to protect its digital infrastructure. They have an in-depth understanding of the company’s systems, policies, and culture. Their responsibilities as previously detailed, include continuously monitoring internal networks, implementing security measures, responding to incidents, and ensuring compliance with internal policies and regulations.  

External Cyber Security Analysts, on the other hand, work for third-party security firms or as independent consultants. They provide specialized expertise to multiple clients, often conducting security assessments, and audits. They offer a fresh perspective on security vulnerabilities and provide recommendations for improving an organization’s security posture. Outside analysts are sometimes brought in for certain projects or to handle security issues. However, they may not have the same level of familiarity with the company's internal systems as internal analysts do.

Salaries for Cyber Security Analysts can vary significantly based on experience, location, and the specific industry. According to recent data: 

• United Kingdom: The average salary for a Cyber Security Analyst is approximately £40,000 per year. For those with more experience and advanced certifications, salaries can exceed £60,000 annually. 
• United States: The average salary for a Cyber Security Analyst is about US$90,000 per year. In major tech hubs like Silicon Valley, salaries can go beyond US$120,000 annually. 

These figures highlight the lucrative nature of this career, reflecting the high demand for skilled professionals in the field. Entry-level positions may start lower, but with experience and additional certifications, there is significant potential for salary growth.
