DHS and SecureLogix Battle TDoS

We're also researching crucial defense strategies for businesses, individuals, and the government when they're faced with Telephony Denial of Service (TDoS) attacks.

Lock-tight caller authentication will be the key, and our work under the DHS' Cyber Security Division's Science and Technology Directorate could unlock next-gen voice network security capabilities.
