Teros develops quick-to-deploy, self-configuring security appliances that protect web servers, web applications and databases from known and undocumented security vulnerabilities and attacks without relying on signatures. Teros customers are Fortune 1000 companies, government agencies, and large web site operators that need to protect sensitive web-based applications and data from unauthorized access or malicious use, and comply with regulatory requirements such as HIPAA and California Law on SSN Confidentiality. At the heart of the Teros Gateway is a web application firewall that reduces web application vulnerability to near zero by protecting against threats that are not detected by network-based firewalls and intrusion detection systems. The Teros Gateway operates at the application layer and uses patent-pending technology that learns an application's behavior, inspects incoming and outgoing traffic, and allows acceptable behavior to be executed while blocking unacceptable behavior. As a result, it protects against known and undocumented security vulnerabilities and attacks without relying on signatures.
