What are Talos Intelligence and Barracuda Reputation Insights?

Talos Intelligence (owned by Cisco) provides reputation data used by corporate security filters, Cisco email security appliances, and other enterprise systems. Their web lookup shows IP and domain reputation scores.

Barracuda Reputation Insights shows your status on Barracuda's blocklist network. Barracuda appliances are widely deployed in corporate environments, making their reputation data influential for B2B deliverability.

Both services provide perspective beyond consumer mailbox providers. A sender might have clean reputation at Gmail but face blocks at corporate destinations using these filters.

These tools are particularly important for senders targeting business audiences where enterprise security appliances filter incoming mail.

Talos and Barracuda are the corporate port authorities. They maintain their own ship registries and inspection standards, separate from the consumer harbors like Gmail and Outlook.
