Radware Ltd. — 2 prefixes (MA-L)

A MAC address beginning with 00:03:B2 or 2C:B6:93 belongs to Radware Ltd., an Israeli-founded network security and application-delivery vendor, and typically appears on enterprise or service-provider infrastructure — DDoS mitigation appliances, application delivery controllers, or web application firewalls — rather than laptops, phones, or other consumer endpoints.

Radware was founded in 1997 and trades on NASDAQ under RDWR, with US headquarters in Mahwah, New Jersey and international headquarters in Tel Aviv, Israel, as part of the RAD Group. The IEEE registry holds two independent MA-L (24-bit) OUI blocks for Radware, with no MA-M or MA-S assignments found in the local registries.

Radware's product line spans the Alteon application delivery controller, DefensePro and Virtual DefensePro DDoS mitigation appliances, AppWall and Cloud WAF web application firewalls, and the APSolute Vision management appliance. Radware's own support knowledge base ties the 00:03:B2 prefix specifically to APSolute Vision devices, giving vendor-side device-type corroboration for that block.

The registry address for 00:03:B2 is malformed — a garbled street name and a placeholder postal code — while 2C:B6:93 carries a clean Tel-Aviv address. IEEE's public OUI data publishes no assignment date for either block; any "registered" date shown by third-party lookup tools is a database artifact, not an IEEE fact.

Because Radware appliances typically sit at the network edge or core, a Radware-prefixed MAC on a network flags infrastructure rather than an endpoint. Radware has disclosed vulnerabilities in its product line, including a critical (CVSS 9.1) HTTP request-smuggling flaw in Cloud WAF versions before May 2025, tracked as CVE-2024-56523.

Analyst note

A Radware-prefixed MAC identifies network security or application-delivery infrastructure, not an end-user device; treat it as a flag for enterprise/service-provider equipment on a network scan.
