Security

Integrated wireless intrusion protection offers threat protection and mitigation, and eliminates the need for separate RF sensors and security appliances
IP reputation and security services identify, classify, and block malicious files, URLs and IPs, providing comprehensive protection against advanced online threats
Integrated Trusted Platform Module (TPM) for secure storage of credentials and keys

Networking on a budget

With the integrated BLE and supporting 802.3af power, the Series APs enable enterprises to improve their work efficiency and productivity with the lowest TCO. When Ethernet drops are not available, VPN tunnels extend remote locations to corporate resources and wireless mesh connections.

Highly secure and reliable performance

The Series APs offer improved network simplicity and security in several ways. Dynamic Segmentation automatically enforces real-time, device-level access policies on Aruba wired and wireless networks. Additionally, Aruba AppRF technology leverages deep- packet inspection to classify and block, prioritize, or limit bandwidth for over 2,500 enterprise apps or groups of apps.

Flexible management options

Available management solutions include Aruba Central (available in cloud-managed and on-premises options), as well as Aruba AirWave, which supports multi-vendor networks. APs can be deployed with zero-touch provisioning to reduce deployment time, centralize configuration, and simplify inventory management.
