Cyber Security Internship-8 week summer placement in London

At Gallagher, we help clients face risk with confidence because we believe that when businesses are protected, they’re free to grow, lead, and innovate. You’ll be backed by our digital ecosystem: a client‑centric suite of consulting tools making it easier for you to meet your clients where they want to be met. Advanced data and analytics provide a comprehensive overview of the risk landscape at your fingertips. Here, you’re not just improving clients' risk profiles, you’re building trust. You’ll find a culture grounded in teamwork, guided by integrity, and fueled by a shared commitment to do the right thing. We value curiosity, celebrate new ideas, and empower you to take ownership of your career while making a meaningful impact for the businesses we serve.

This 8‑week work experience placement is designed to provide a practical, structured introduction to cyber security within a large global professional services organisation. You will gain exposure to how cyber and information security operates in a real‑world business environment, supporting both UK and EMEA activities, and working closely with the Cyber Security team. The placement is designed to be educational and developmental, balancing observation, hands‑on support, and guided learning. It does not require prior cyber security experience, only an interest in technology, security, and how businesses manage cyber risk. This will be based from our London Lombard Street office and will be regularly on site. The start date is 1st June and this is a paid internship.

The Global Cyber & Information Security (GCIS) team is responsible for protecting Gallagher’s information, systems, and technology estate against cyber threats. The team works across regions and business units, partnering closely with IT, legal, risk, compliance, and business leadership.

With an educational focus, you will gain exposure to cyber security fundamentals and how security supports the wider business.
