Still Running Net.Data on IBM i? We Can Help

November 13, 2026/0 Comments/in Security /by Alan Seiden

Net.Data, a web scripting language dating back to the AS/400 and iSeries era, still works on today’s IBM i servers. How can you tell if you are running Net.Data? Often having db2www or .mac in its address, a typical URL looks like this:

/cgi-bin/db2www/orders.mac/main

If your Net.Data applications have not had a security review in years, it is time to take a closer look. An application can keep working while vulnerabilities go unnoticed. Net.Data predates modern web security frameworks, requiring extra care to protect the server from modern security threats, especially AI-powered bots.

If your business depends on Net.Data applications, Seiden Group can help you assess the risks, address vulnerabilities, and plan for their future.

Whether you need a security review, ongoing support, or a migration to another language, such as PHP, Node.js, Python, or Java, we can help you choose the next step.

Contact Seiden Group to discuss your Net.Data applications, or to confirm whether you have one.
