StopCut is a small Windows utility designed to guard a computer on a local network against ARP poisoning and spoofing. It protects the PC's ARP tables from flooding or falsified address changes that can redirect traffic or disrupt connectivity, including attacks associated with NetCut. The program requires WinPcap 3.x and targets older Windows releases through Windows 8.

StopCut is a lightweight network utility for Windows that aims to protect a computer on a local area network from ARP poisoning and spoofing. These attacks manipulate address information used by devices on a LAN, potentially redirecting network traffic through another computer. StopCut is intended for users who want to guard their own connection against this type of interference, including attempts to disrupt access with tools such as NetCut.
The program focuses on protecting the computer's ARP tables from flooding or unauthorized changes. On a local network, devices use ARP to associate an IP address with a hardware address. If those associations are falsified, traffic may be sent to an unintended destination. StopCut works to prevent that redirection on the protected PC; it is a local safeguard rather than a general network monitoring or firewall suite. Its purpose is to reduce exposure to traffic interception and connection disruption associated with ARP spoofing.
This focus is relevant on shared networks where other connected devices may be untrusted. ARP-based interception can put unencrypted traffic at risk and may expose activity or credentials, while encrypted connections have their own protections. StopCut does not replace secure websites, strong account practices, antivirus software or network-level security controls. It is also not a tool for recovering compromised passwords or investigating other computers; its role is to protect the local system's network address resolution from spoofing attempts.
StopCut is a small, focused application rather than a full network administration package. It is suited to users who need a basic countermeasure for ARP poisoning on a LAN, particularly where connection interruptions or suspected traffic redirection are a concern. It addresses a specific network-layer threat and does not claim to block unrelated malware, phishing, or attacks that do not rely on ARP manipulation.
The program is freeware and requires WinPcap 3.x. Its stated operating-system support covers older Windows releases through Windows 8, including 64-bit editions where indicated; Windows 10 and Windows 11 compatibility is not established. Because it depends on WinPcap and targets legacy Windows versions, users should check whether its capture driver and network functions work with their current system before relying on it. The download is approximately 1 MB.
