AT&T Dynamic Defense
Network Defense — security built into your connection.
Most security tools sit on individual devices and react after a threat arrives. Network Defense works one layer earlier — inside the AT&T network itself — stopping ransomware, phishing, and malicious traffic before it ever reaches your computers, point-of-sale, or phones.
What it is
Protection at the network, not just the device.
Antivirus protects a laptop. Network Defense protects everything that touches your internet — and it does it before the threat reaches the device.
- Powered by AT&T's Chief Security Office threat intelligence
- Dynamically blocks malicious IPs, zero-day attacks, and botnets
- Security controls execute inside the network, ahead of your firewall
- Covers every connected device — computers, POS, phones, cameras, IoT
- No appliance to buy or maintain; it rides your AT&T connection
Why "before the device" matters
The attacks that take businesses offline for a week usually slip past device antivirus. Blocking them at the network is the difference between a non-event and a shutdown of payments, phones, and operations.
