What our clients say

“Invaluable to helping grow our data strategy”

Gladstone Brookes

“We have been very pleased with the outcomes of working with CSS Assure. With their advice and guidance we have been able to develop and implement a full cyber security infrastructure. Having a CISO within the company was important to us so they provided a comprehensive training and mentoring programme to support to a key member of staff to move into this role. Their contribution at board level has been invaluable in growing our data strategy.”

“Very easy, enlightening and rewarding”

Money Management Team

“Working with CSS Assure has been very easy, enlightening and rewarding. We were aware we needed to increase our cyber resilience. We were glad we could rely on their support and guidance to roll out a full cyber security programme across all areas of our business. Their input and advice with cyber insurance reassured us that we had appropriate cover for the scale and nature of our business. We have always found them to be extremely knowledgeable and insightful especially with respect to their ongoing support of our senior management team.”
