Corero and Juniper Networks Expand Existing Agreement

Corero (AIM: CNS) (OTCQX: DDOSF), the distributed denial of service ("DDoS") protection specialists, today announced a strategic expansion of its partnership with Juniper Networks ("Juniper"), enabling Juniper to now sell Corero's full portfolio of DDoS protection solutions to customers with any network infrastructure configuration.

This expanded partnership further strengthens Corero's existing relationship with Juniper and is expected to facilitate joint new business opportunities, specifically with tier-one telecommunication providers and enterprises with mixed network environments. Previously limited to Juniper-only deployments, Corero's technology now extends its industry-leading sub-second detection and mitigation to multi-vendor networks through a unified code base supporting both Juniper's ephemeral configuration and BGP FlowSpec for non-Juniper routers.

Carl Herberger, Chief Executive Officer at Corero, commented:

"Corero's partnership with Juniper has played a key role in our joint growth for almost ten years, and I am delighted to be expanding our successful relationship via this mutually beneficial contract extension. This latest joint product offering positions Corero and Juniper well to service tier-one telcos and enterprises, opening up further growth opportunities for both parties and, importantly, incentivises Juniper's leading sales team to sell a broader range of our award-winning DDoS protection products.

Alliance partnerships like this continue to provide Corero with an unparalleled route to market as we remain focused on accelerating our go-to-market strategy and delivering footprint expansion across the globe."
