Board and senior management changes

Corero Network Security plc (AIM: CNS), the AIM listed network security company, is pleased to announce that Andrew Lloyd, currently a non-executive director of the Company, has been appointed President and Executive Vice President Sales and Marketing for Corero. Andrew will move into an Executive role on the Board following his appointment.

Andrew Lloyd has been involved in the IT software and systems sector for more than 25 years. His career has included successful roles with large corporations including Oracle and Computer Associates, as well as high-growth ventures including PrismTech and, most recently, private equity-backed Workplace Systems.

At Oracle, over an eight year period Andrew held a number of leadership sales roles on both sides of the Atlantic. Thereafter, as VP Security Management at Computer Associates ("CA"), Andrew was responsible for sales and marketing of CA's security management business (known as e-Trust) across the EMEA region.

From 2008 to 2013, Andrew held the position of Senior Vice President of PrismTech Group's OpenSplice business. In 2013 he joined Workplace Systems, where he was Chief Customer Officer and part of the leadership team which subsequently sold the business to US-based WorkForce Software in June 2016. Following the sale, Andrew was appointed SVP Sales for WorkForce Software with responsibility for leading the sales teams in EMEA and Asia Pacific regions while completing the post-acquisition integration of the Workplace Systems business.

Andrew will be responsible for leading Corero's commercial expansion and sales growth.

In conjunction with Andrew's appointment, Dave Larson, Chief Operating Officer, will be leaving Corero to pursue other interests. Dave Larson was not a Board member but considered a PDMR.

Jens Montanana, Chairman of Corero, commented:

"We are delighted that Andrew has agreed to join Corero as President and Executive Vice President Sales and Marketing. His skillset and experience of both growth companies and large multinationals will be invaluable as we drive our revenue growth and establish Corero as a leading player in the DDoS mitigation market."
