Using Valid IP Range Settings to Control Cetec ERP Access

Cloud deployment means your team can open Cetec ERP from almost anywhere with an internet connection. For many manufacturers, that flexibility is a major advantage for leaders, sales teams, and administrative users who need to check on jobs or reports while away from the plant.

In other environments, especially where sensitive customer data or export-controlled information is involved, wide-open access is not acceptable. IT and compliance teams may want Cetec ERP available only from specific locations on a secure company network. The Valid IP Range configuration setting is the control that lets you make that decision.

What the Valid IP Range Setting Does

The Valid IP Ranges configuration setting limits user access to Cetec ERP based on the IP address of the device they are using. When you define one or more approved IP addresses in this setting, users can only sign in when their traffic originates from those addresses. Attempts to log in from a different network are rejected, so employees cannot use Cetec ERP while off site or on an unapproved connection.

In practice, this usually means tying Cetec ERP access to your office network, plant network, or company VPN. Your internal users keep full access when they are on duty and connected to that network, and you reduce the risk of someone opening sensitive data from an unmanaged device or public Wi-Fi.

How to Configure Valid IP Ranges in Cetec ERP

To set up this control, an administrator in Cetec ERP navigates to Admin, then Config Settings, and searches for "Valid IP Ranges." In that configuration field, you enter the IP addresses that should be allowed to access your Cetec ERP instance. After you save the setting, users must be connected through one of those addresses in order to log in successfully.

If you decide that remote access is acceptable for your manufacturing business, you can leave this field blank and allow users to connect from any network, subject to your normal user and password controls. If you need tighter data security, you can populate the field and explicitly tie access to your controlled network perimeter or VPN.

When to Restrict Cetec ERP Access by IP Address

Many small and mid-sized manufacturers are comfortable with browser access from home offices, customer sites, or travel as long as user logins are well managed. Others, especially those supporting government contracts, ITAR-related work, or strict customer security requirements, prefer to keep all Cetec ERP access on a tightly controlled network. In those environments, Valid IP Range becomes one of the basic controls IT and quality teams can point to in security and compliance reviews.

A practical way to decide is to look at where your team truly needs Cetec ERP access to do their jobs. If the work happens on site and your policies already require employees to be on premises to handle production and order management, restricting access to on-site IP addresses keeps your system behavior aligned with that expectation.

Key Takeaways

• Cetec ERP is web-native and can be accessed from almost anywhere, but some manufacturers prefer to keep access on a controlled network.
• The Valid IP Ranges configuration setting restricts logins to specific IP addresses, blocking access from unapproved locations.
• Configuring Valid IP Ranges is handled by an administrator in Admin, Config Settings, using the "Valid IP Ranges" field.
• Use this setting when you need Cetec ERP access to stay on site or on a secure VPN as part of your broader security and compliance controls.

Conclusion

Remote access to Cetec ERP can be a practical advantage or a risk, depending on your environment. The Valid IP Range setting gives your manufacturing business a simple way to match system access to your security policies, either allowing users to connect from anywhere or requiring them to work from defined, approved networks.
