CUSTOMER WIN

Digital enterprise customer order $0.7 million

Corero Network Security plc (AIM: CNS), the global network security company, is pleased to announce a $0.7m order for its SmartWall® Threat Defense System ("SmartWall") technology from an existing digital enterprise customer.

The order is part of this customer's ongoing deployment and includes multiple SmartWall products with supporting SecureWatch® services for three years. Corero has generated orders of $1.0m from this customer in 2018 (orders which the Company reported in the Trading Update dated 21 December 2017 were delayed to 2018).

Further additional orders are expected in the second half of 2018 as part of the customer's ongoing global expansion and SmartWall deployment plan.

Andrew Lloyd, Corero President and EVP Sales and Marketing, said:

"The delivery of real-time DDoS protection is fast becoming the critical component in the defence against large scale cyber breaches and this expansion order provides further confirmation that SmartWall and our SecureWatch service combine to deliver on our protection promise.

With many digital enterprise organisations now adopting a zero tolerance approach for any degraded performance or service downtime from a DDoS attack, the resulting potential loss of revenue, reputation or regulatory breach continues to fuel our new business momentum."
