ORF is our award-winning spam filtering software for Microsoft® Exchange Server.

Layered protection

No single technology catches all spam. The 23 layers of tests in ORF ensures the maximum detection rates.

ORF ♥ administrator

From the industry's best logs to the friendly UI, ORF works for the administrator, saving time, resources and sanity.

No false positives

Never miss an important email again. ORF ships with multiple dedicated tools against false positives.

Proven performance

Deployed at 11,000 organizations in 112 countries, ORF filters thousands of emails every second, 24 hours a day.

ORF is an amazing product that was incredibly easy to install on our existing infrastructure and started working immediately after installation and configuration. It has significantly reduced the amount of spam that is delivered into our mailboxes and with minor adjustments, those that do slip through once, are rejected after minor tweeks. I would highly recommend this product to any organisation that wants to reduce the number of spam messages delivered to their organisation’s mailboxes.
