Client Feedback

Listen to what our clients have to say about our consultancy services

"In order for BMJ to the right way forward we looked for a VCISO to advise us on the right way to do things and give us expertise. We went to Cyber Management Alliance and it's been about a year now and we ran workshops, looked at our response to incidents, created the incident response plan and we are in a position now where we understand our way forward. Our VCISO keeps us on our toes and overall it's been a very effective way of delivering expertise into the organisation that we wouldn't have normally had."

Aaron Townsend, Service Delivery Manager, British Medical Journal
