Layered protection

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

ORF ♥ administrators

From the industry's best logs to the friendly UI, ORF works for the administrators, 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 15,000 organizations in 118 countries, ORF filters thousands of emails every second, 24 hours a day.

Technology Highlights


Does one thing. Exceptionally well.

ORF is designed from ground up to catch spam. This clear focus enables dealing with spam very efficiently, free of the compromises and complexities that cripple all-in-one systems so often.

A blend of technologies

There is no single technology that would stop all junk emails, so ORF does the next best thing and forges the industry's best performing anti-spam technologies together into a unified, rich and extremely effective framework.

Configurable to every detail

Your responsibility for providing uninterrupted email service finally comes with the power to achieve that. ORF can be customized to your organization, your requirements and your emails.

Simple and friendly user experience

Your average enterprise software cares little about the person who uses it. Experience something different with ORF which we crafted carefully with the administrator in mind.

Enthusiastic technical support

We believe a great customer service is personal, friendly and knows the deal, so we made ours just like that. To be there for you, our technical support is available free of charge without contract, even during planning and evaluation.

Business Highlights


No tolerance for false positives

If your email filter has ever lost an important email, you know it is real pain. The distinguished focus of ORF on preventing false positives saves you the frustration and guarantees business continuity.

A proven solution

ORF has been the choice of over 15,000 organizations in 118 countries around the world since its 2002 launch. Today, ORF filters thousands of emails every single second.

Low administration cost

Even the most fire-and-forget solution requires the administrator's attention occassionally. We know that is not for free, so to save you money, we made sure that maintenance tasks are simple, intuitive and well-documented.

Hassle-free licensing

Just a few highlights: licensed per actual user (not per mailbox); unlimited servers; free and unlimited technical support; and many more.

Affordable

Starting from $80 / 10 users / 1 year with significant volume discounts, ORF Fusion is the best value on the market.
