Port 1762: cft-1 — Axway Transfer CFT's First Channel

What This Port Is

Port 1762 is cft-1, the first of seven consecutive ports (1762 through 1768) registered with IANA for Axway Transfer CFT. ¹

CFT stands for Cross File Transfer. It's a managed file transfer (MFT) product built for enterprise environments — the kind of infrastructure that quietly moves payroll files between mainframes, syncs inventory data across ERP systems, and handles batch transfers that businesses depend on but never think about.

The seven reserved ports (cft-1 through cft-7) give Transfer CFT dedicated channels for different types of connections: plain PeSIT protocol, SSL-encrypted PeSIT, administrative interfaces, and integration with Axway's Central Governance platform. Port 1762 in particular is commonly used for SSL-secured file transfer sessions. ²

Who Actually Uses This

Transfer CFT is an old product in the best sense: it's been doing its job reliably for decades in industries where reliability is everything. Banks. Logistics companies. Government agencies. Healthcare systems. Anywhere that needs to move large files between heterogeneous systems with audit trails and delivery guarantees.

If you're running Transfer CFT, these ports are configured deliberately and your network team knows about them. If you're not running Transfer CFT, port 1762 should be quiet.

Security Notes

Historically, some security scanners flagged port 1762 due to associations with older malware that used unusual ports as communication channels. This is the usual story with registered ports: the port number itself is neutral. What matters is what's listening. ³

If you see unexpected traffic on port 1762 on a system that doesn't run Transfer CFT, investigate it.

How to Check What's Listening

On Linux/macOS:

# Show what process is using port 1762
ss -tlnp | grep 1762

# Or with lsof
lsof -i :1762

On Windows:

# Show listening ports and their process IDs
netstat -ano | findstr :1762

# Find the process name from the PID
tasklist | findstr <PID>

If nothing is listening: expected. If something is listening and it's not Axway Transfer CFT: look closer.

Why Blocks of Reserved Ports Exist

IANA doesn't just assign one port per product — some applications need multiple ports for different functions. Transfer CFT reserved seven consecutive ports because different connection types (unencrypted vs. SSL, data vs. admin, local vs. governance) benefit from being clearly separated at the network layer. Firewalls can allow or block entire ranges; monitoring systems can route by port.

Seven consecutive ports in one block is unusual. It means whoever registered them either planned carefully or anticipated growth that never required all seven. Either way, the registry holds the reservation, and the Internet routes around it.
