| Forrester’s recommendations on how to combat these threats was provided in
a companion document, "Spam Management Best Practices". Along with some
good advice such as delaying email bounce notifications to help combat
address harvesting and implementing group-level spam policies, the report
listed four "Best of" categories for vendors providing spam blocking
technology:
Best email reputation filters
Best industry blacklists
Best high-performance MTA and anti-spam solution
Best integrated email encryption
The IronPort C-Series email security appliance was the only product
recommended for all four categories and IronPort was the only vendor
recommended from a performance perspective stating that it has
"best-in-class" performance for anti-spam. As the pioneer in
reputation-based email security, IronPort continues to be the vendor to
look to for messaging security in the continually changing Internet threat
environment. |
