Key Customer Contract Extension for new Web Application Security Product

Corero (AIM: CNS) (OTCQX: DDOSF), the distributed denial of service ("DDoS") protection specialists and champion of adaptive, real-time service availability, is pleased to announce it has secured a $1.1 million, 3-year contract for its Web Application Security ("WAAP") with TierPoint, a global provider of comprehensive IT solutions, including colocation data centres and managed cloud recovery services.

First announced in Q3 2025 as part of Corero's CORE platform offering, the WAAP product has been co-developed with TierPoint, extending Corero's product capabilities to support customers with an innovative WAAP solution.

Following completion of the development phase, and a successful production implementation, Corero has secured a $1.1 million, 3-year contract to provide WAAP services to TierPoint.

This agreement further strengthens Corero's existing partnership with TierPoint, one of the world's leading data centre providers. Furthermore, successful deployment of Corero's WAAP product demonstrates the continued commercial success of the CORE platform and the growing customer need for innovative and market-leading cybersecurity solutions.

Carl Herberger, CEO of Corero, commented:

"I am pleased to extend and deepen our partnership with TierPoint, a key customer and partner, and a global leader in the ever-expanding data centre market.

Our WAAP product, along with other capabilities of the CORE platform, provide non-DDoS revenue opportunities that were not available to Corero two years ago."

Paul Mazzucco, Chief Information Security Officer of TierPoint, commented:

"The Corero WAAP solution is really correcting the WAAP market gaps in my opinion. The launch is key to enhancing our corporate and our customers' application security needs and expanding TierPoint's growing security offering.

Corero is a key partner to TierPoint, and I am delighted to extend our partnership once more."
