Vulnerability Insights

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.
