Add an extra layer of protection to help prevent network attacks.

Use software defined perimeter (SDP) to defeat network-based attacks.

Adversaries continue to get inside your network. A zero-trust security approach is based on the belief that businesses should not automatically trust users or devices inside or outside the network perimeter.

Verizon Software Defined Perimeter (SDP) applies this zero-trust approach to networking for remote-access, internal network segmentation and cloud applications. Verizon SDP can defeat network-based attacks to give you peace of mind.

What is Software Defined Perimeter?

SDP is a protocol specification created by the Cloud Security Alliance that is “designed to provide on-demand, dynamically provisioned, air-gapped networks”1 that are better equipped to defeat network-based attacks. Verizon SDP differentiates itself from other Software Defined Perimeter solutions by being a high-performance implementation of this protocol.

How does Software Defined Perimeter work?

Verizon SDP authorizes users' access to network resources. It isolates servers to defeat server exploitation of vulnerabilities and configuration errors. It integrates multifactor authentication to defeat credential theft, including pass-the-hash. And, SDP builds mutual TLS tunnels to defeat man-in-the-middle attacks.

Architecture of the Verizon SDP service

Verizon SDP Controllers and Gateways are virtual machines that can be located wherever they are needed. Each Verizon SDP instance is dedicated to a single customer — not shared with others.
