What does SynapsInt?

SynapsInt enables you to search a wide range of digital identifiers through a single interface. Rather than maintaining its own proprietary database, it queries numerous publicly available sources and presents the results in a consolidated format.

Searches can include email addresses, usernames, domains, IP addresses, phone numbers, cryptocurrency wallets, social media accounts and organisations. Depending on the identifier, results may include associated infrastructure, publicly available account information, technical records and links to external sources.

The lowdown: The platform helps accelerate the collection phase of an investigation by reducing the need to search multiple OSINT tools individually.

How to Use:

1. Choose the appropriate search type (e.g. email, username, domain, IP address or phone number) and enter your target into the search bar.

2. Review the aggregated results, paying attention to linked accounts, infrastructure and external references.

3. Validate significant findings using authoritative sources and use the discovered information to pivot into further investigation.
