“Organizations around the world, regardless of their size and marketplace, are rapidly realizing that their networks are the constant target of cyber attacks. These attacks negatively impact network performance and ultimately have a detrimental effect on their business, which has elevated intrusion detection and prevention as a chief concern,” said Ron Brumback, president and CEO of Top Layer Networks. “Our market-proven technology positions us as the leader in intrusion prevention, providing companies with the essential elements for a comprehensive response to the growing number of attacks. We are fortunate to have attracted a strategic investment group that provides much more than capital – most notably a broad global reach – and we look forward to working with our partners to deliver industry-leading products as we aggressively expand worldwide.”

Top Layer utilizes its deep network infrastructure origins and extensive experience in both ASIC and embedded software development to build inline security appliances with the purpose of actively blocking attacks and preventing intrusions.
