Ninja Email Security has a dedicated image-spam detection engine |
Image
spam plays by different rules, designed to defy the old standard antispam
practices that the other guys still try to use. Only Ninja Email Security
for Exchange gives you a dedicated engine designed to beat image spam
at its own game, and kill it.

Mutation-proof:
In addition to its own image-spam engine, Ninja leverages the built-in
Cloudmark engine to "fingerprint" image spam. Even if images
mutate from one day to the next, the fingerprints don't. This one-two
punch is murder on text spam too.
Ninja is the all-in-one, best-of-breed, third-generation
email security solution: Ninja's plug-in architecture
integrates policy-based antispam, antivirus, attachment filtering,
and disclaimer modules on your Exchange server.

Policy-based control:
Ninja's extensive policy creation capabilities help ensure messages
are handled properly according to your company's business process
and security policies.
Smart attachment filtering:
Ninja has the first policy-based attachment filter. It polices attachments
based on email direction - inbound, outbound or within the organization.
Additionally, Ninja looks inside many types of files to see their
true identity, rather than blindly trusting file extensions, which
can easily be faked.
Dual-engine antivirus: Ninja combines the
power of two high-quality AV engines: Authentium and BitDefender.
Disclaimers:
Ninja's Disclaimer plug-in provides global and user-based disclaimers
for all outbound email. You can configure policy-based disclaimers
based on specific users, groups, domains, or public folders.
