SPAM
BLOCKING Now you can block up to 98%
of spam with industry leading low false positive rates through
the latest and most comprehensive spam filtering and email
defense technology.
Multi-layer Spam Filtering
Five is better than two. Unlike most spam filtering solutions
- which use one or two spam-classification techniques - we
use a Stacked Classification Framework(SM) – that aggregates
the five most effective spam filters and techniques in the
industry. These include:
- Bayesian Statistical Analysis
– Statistical algorithms identify
and quantify the possibility that an email message is spam.
Bayesian analysis is based on how often certain spam-like
elements within the email have appeared previously in other
spam emails.
- Heuristics Rules-Based Analysis
- Thousands of proprietary “rules
of thumb” recognize the characteristics of spam and
measure them against incoming mail. These rules are written
by threat technicians and are updated as new spamming methods
are identified.
- Distributed Checksum Clearinghouses
- Takes a checksum or fingerprint,
of all email messages it sees and places those fingerprints
in a database. If the database recognizes a large number
of exact matches or at least very similar fingerprints,
those messages are more likely to be spam.
- Black and White Lists -
Maintained by users, these customized
lists detail sites, individuals or IP addresses from which
mail is and is not allowed.
- HTML Shield Technology
– This feature reduces the on-going
influx of spam by blocking web beacons and bugs. These are
methods used by spammers to monitor the reading of email
and identify active mailboxes.
Each of these five filters dynamically calculates
the spam probability of every message. Through an aggregation
and analysis of these spam-likelihood scores, we offer an
extremely effective spam blocking solution.
All suspect emails are moved into a
quarantined area. Emails identified as spam are stored in
this external area. You determine whether to remove, release
or even safely view the suspect messages. All quarantined
content is accessible through your spam quarantine report.
