Halon Protect Reviews & Product Details

The amazing Halon Scripting Language allows us to configure Halon to literally do anything we want.

It's allowed us to create a custom MTA that has all but eliminated IP's being blacklisted, and increased deliverability for our customers by well over 1,000%!

We had no issue replacing our old system with Halon, and currently it sends out 10s of millions of emails without any issues. Review collected by and hosted on G2.com.

There is a learning curve if you have no coding experience, however Halon themselves are happy to set up your configuration to your specifications. So it's only an issue if you plan on doing it all yourself. Review collected by and hosted on G2.com.

It is allways working och one can modify it to append/comply to almost anything.

Right now I can not find any dislikes anbout Halon... Review collected by and hosted on G2.com.

Halon Protect offers unmatched functionality, flexibility, and stability. But what probably matters more is the end result for us as an e-mail service provider. Halon Protect, simply put, does exactly what it was designed to do, it keeps unwanted e-mail traffic from your and your customers' inbox. Review collected by and hosted on G2.com.

I really can't think of anything negative to say about Halon. As strange as that sounds, we haven't run into anything that hasn't been resolved in a timely manner. Review collected by and hosted on G2.com.

There is a very simple premise to Halon and that is you get a blank slate to implement any number of ideas when it comes to SMTP mail processing.

Industry compliant but still flexible enough to create any number of paths to filter and monitor SMTP data.

Simple deployments from single node to clusters to HA.

Support is top notch, no question too simple or too silly, they come up with some creative answers to curly problems. Review collected by and hosted on G2.com.

There is a steep learning curve, but if you understand general SMTP mechanics then you will be just fine. Review collected by and hosted on G2.com.

Unbelievably effective email MTA at scale. The support staff is top-notch. We have the system configured as a high volume inbound and outbound SMTP server, configured in a cluster of nodes that span multiple countries.

We use the service for anti-spam, anti-virus, and SMTP with user authentication against an API.

Upgrades have been seamless, stability has been world-class and their approach to engineering is beyond reproach.

We replaced 70 postfix servers with 7 Halon nodes and we could have probably done it with 4! Review collected by and hosted on G2.com.

Message queues are located on the machine that accepts the email. If there are hardware issues or if we need to drain messages from a specific node it takes time and a lot more tweaking than we would prefer. Review collected by and hosted on G2.com.
