What signals to you share apart URLs and IP addresses?

The Global Signal Exchange supports a variety of signal types:

• Domain Name (e.g., domain.com)
• Hostname (e.g., something.domain.com)
• Blockchain Internet Identifier ('Blockchain Domains')
• CIDR block
• Email address
• IBAN
• IP address
• Phone number
• URL (e.g., https://something.domain.com/pathname)

At the outset, the GSE is encouraging organizations to share the following signal types as a priority:

• Domain Name (e.g., domain.com)
• Hostname (e.g., something.domain.com)
• IP address

These are typically the least contentious data to collect (with limited, if any, access to Personally Identifiable Information), but they are useful signals to share with others and collate to help identify bad actors in the fight against scams and fraud.

The GSE Platform offers a 'Marketplace' of threat feeds, a service that displays the number of feeds available to consume. Currently, we have a number of 'Open' and 'Commercial' feeds providing threat signals comprising Links and IP Addresses. We also have a number of private feeds which support other signal types:

• blockchain domain names,
• telephone numbers,
• and more.

Accredited organizations can review the 'Sending Signals' section of the GSE Platform to review the latest supported signal data types.

Can I use the GSE to receive private data from others?

Yes. Other users can choose to share their private data with you on the GSE platform.

Who else apart from Google is sharing threat signals?

As a founding partner, Google is committed to providing signals intelligence to help tackle online scams and fraud. The GSE serves as a single global clearinghouse for Google and other organizations to share signals, reducing the friction and legal complexity of managing numerous bilateral signal-sharing arrangements worldwide.

Currently, Google is rolling out several signal services through its brands (Chrome, YouTube, etc.). In 2025, the first Google signal-sharing service to launch was for Google Shopping, offering cloaking, scam, and spam threat signals.

Follow our blog to keep up with the latest news about feeds as they are made available to users of the GSE Platform.

In addition to the signals provided by Google, the GSE also offers signals from the commercial, open-source, and private sharing sectors.

You can easily view the latest count of GSE signal feeds by visiting the Feed Count widget at the top of the GSE Website Home Page.

Is the GSE Platform very expensive?

There are no set prices for gaining access to the GSE Platform and data feeds. The GSE, as a not-for-profit, aims to offer high-quality, global, real-time threat intelligence to tackle online scams and fraud. The online scam and fraud industry is a multi-billion dollar business, benefiting criminals who gain rich rewards with little or no justice.

Despite the considerable investment by many in the internet supply industry to tackle online scams and fraud, these issues continue to proliferate, and the situation demands a change in tactics. Better information is needed to inform potentially new regulation and improved coordinated activity among stakeholders.

The need for "better data sharing" was identified by a multi-stakeholder group at the Global Anti-Scam Summit in Lisbon in 2023. With the generous help of Google, the Global Signal Exchange was established in 2025 in partnership with OXIL/DNS Research Federation and the Global Anti-Scam Alliance to deliver signal-sharing for the benefit of the wider internet community and the protection of consumers.

The Global Signal Exchange relies upon a mix of funding from big tech platforms, banking, internet industry suppliers, and others. We ask all organizations to make a reasonable contribution to help fund our services, research, and further development of services to protect consumers.

We are also developing a number of FREE services for those who need help, such as small businesses, public safety organizations, and those who have valuable intelligence to share. In addition to this, we offer FREE public services, such as our internet industry League Tables.
