Cyber Security

Since 2008 we have provided our clients with bespoke, personal and expert cyber consultancy. We believe strong cyber defences can only be built on a combination of well-trained people and sound policies, underpinned by correctly-configured technology. We work with clients to understand their particular needs and develop secure solutions.

Our technical team brings the benefit of several decades' experience in technology, the intelligence services, information security, international regulations and more. We combine this with corporate understanding to ensure our advice is presented in a way which clients not only understand but, crucially, use to enhance their business.

G3 Cyber clients include global corporations, international law firms and private clients with family offices.
