Blacklisted IP Detection
Scrubbing identified IPs against reputable organisations' blocklists to detect addresses that have been flagged for malicious activity.
Key capabilities
Multi-source blocklist check
Checks your IPs against dozens of reputable blocklists including Spamhaus, AbuseIPDB, and other threat intelligence sources.
Reputation scoring
Provides a composite reputation score for each IP based on its presence across multiple blocklist databases.
Root cause correlation
Links blocklist entries to underlying issues such as compromised servers, open relays, or malware infections that caused the listing.
Delisting guidance
Provides step-by-step instructions for requesting removal from each blocklist once the underlying issue has been resolved.
Why it matters
Blacklisted IPs cause email delivery failures, blocked web traffic, and reputational damage, often without the organisation knowing until customers complain.
