About zerospam
At a glance
zerospam is a cybersecurity company specializing in Email & Messaging Security, founded in 2003 and headquartered in Montreal, Canada. It was acquired by Hornetsecurity in 2021.
Zero Spam operates an enterprise-grade reputation engine that identifies and blocks spam, malicious registrations, and bot activity. The platform combines community intelligence from over 50,000 contributors with AI-powered analysis to detect threats in real-time with sub-10ms latency. The service offers two primary deployment methods. For non-technical users, Zero Spam provides WordPress plugins that integrate directly into content management systems, automatically filtering spam registrations and bot comments without requiring CAPTCHAs or user interaction. For developers, the platform offers a RESTful API built on WordPress REST API architecture that enables integration into web application firewalls, checkout flows, registration forms, and other high-throughput environments. The threat detection system draws from three intelligence sources: crowdsourced reporting where blocked threats are shared across the network, AI neural networks that analyze patterns in email syntax and subnet usage, and honeypot traps deployed across the web that trigger immediate global bans upon interaction. The database contains over 120 million records with comprehensive IP and email reputation scoring. Zero Spam provides detailed logging and reporting of spam attempts, including IP address analysis, email validation, threat confidence scores, country information, and abuse history. The platform includes built-in object caching and rate limiting for performance optimization. Pricing tiers range from a free explorer license with 10 requests per month to unlimited platform licenses supporting multiple sites and applications.
