PDMR Change; Strengthening of the Sales Organisation with a new Go-To-Market Configuration

Corero Network Security plc (AIM: CNS), a leading provider of real-time, high-performance, automatic Distributed Denial of Service (DDoS) cyber defense solutions, announces that its VP Global Sales, Michael Connolly, a Person Discharging Managerial Responsibility, is pursuing a new career opportunity and therefore leaving the Company. 

The Company will now take the opportunity to strengthen and expand its Sales organisation. It has already begun a recruitment process to hire three new senior executives for a Head of North America Sales, a Head of International Sales and a senior Channel Sales executive.  These new hires will spearhead Corero's drive to both expand the Group's international sales footprint and broaden its blue-chip customer profile. 

In the transition period, the Company plans to create a dual executive leadership structure for North America and Rest of World Sales, with additional executive emphasis on channels, with interim Sales responsibility being split between Ashley Stephenson, for North America and Will Hamber, for Rest of World. 

Lionel Chmilewsky, Corero's CEO, said:

"I would like to thank Michael for his service to the Company and we wish him well for the future in his new position.  Separately, I am convinced that the changes we are implementing for the Sales Organisation in the near term will strengthen our position on the DDoS protection market and I look forward to the continuing growth in our business."
