MACsec for Direct Connect:

MACsec (Media Access Control Security) is an IEEE standard (802.1AE) for encrypting traffic at Layer 2. AWS Direct Connect supports MACsec on dedicated connections of 10 Gbps and 100 Gbps capacity. This ensures that all WAN traffic over the Direct Connect connection is encrypted, meeting regulatory requirements.

Does Not Affect Bandwidth:

MACsec operates at the physical layer (Layer 2), and its encryption overhead is negligible. This ensures that the company's bandwidth capacity is not affected.

Existing Direct Connect Connection:

Configuring MACsec on the port of the existing Direct Connect connection avoids the need to establish a new connection, reducing complexity and costs.
