Prevent users from bypassing your filters

Our smart filters will work even when users actively try to circumvent them.

Using Natural Language Analysis and Proprietary Algorithms, our filters are able to detect millions of variations for each unwanted word: letter replacements, character insertions, phonetic variations, leet speak, obfuscation, hyphenation, special characters, embeddings etc.

Detect Personal Information

Automatically detect email addresses, phone numbers from multiple countries, IP addresses, social security numbers and more.

Our email detection filters work even when users actively try to bypass your filters, such as with jane(at)gmail(dot)com or robert_hotmail_com.
