What is AT&T Dynamic Defense?
Built-in threat protection with your connectivity solution
As you adopt as-a-service models, grow your business, and extend your network to the cloud, your network’s attack surface grows. Add-on solutions can be effective, but they add complexity and can strain your resources. AT&T Dynamic Defense helps you stay ahead of ever-evolving threats and have the right policies and protections in place.
Built-in network protection
AT&T Dynamic Defense is the first network solution with threat protection that’s built in. It’s embedded in our global network infrastructure, so it detects threats, filters malicious traffic, and executes security controls before the data reaches your network. As the first line of defense, AT&T Dynamic Defense significantly reduces the overall threat surface that can impact performance or compromise integrity.
Simplified Security
AT&T Dynamic Defense combines multiple security features into a single capability that’s embedded with your connectivity solution. There’s no separate equipment to buy and no hardware needed. You can say goodbye to add-on security solutions from multiple providers and the extra expense, contracts, and maintenance that follow.
Unrivaled Threat Protection
Backed by security experts
AT&T Dynamic Defense employs the same intelligence we use to protect our own infrastructure. Our network is built on deep security expertise. Today our network carries over 1/3 of the world’s internet traffic, giving us insights into new threats as they arise and the ability to immediately block malicious traffic from reaching your network. It’s powered by machine learning (ML) and artificial intelligence (AI), so it adapts to the evolving risk landscape. Now, AT&T Dynamic Defense extends our best-in-class threat protection to your local area network (LAN).
We secure your network like we secure our own—with innovative security tools to detect and prevent cyber threats.
