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.
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
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.

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
