Expert Insight

Hornetsecurity offer a platform suited to protecting email threats. They offer businesses strong protection against malicious emails, spam and phishing attacks. A particular strength is their optional Advanced Threat Protection module, which protects businesses against emerging email threats. The service has a good level of admin features, and concise reports allow admins to have an overview of their email communications. The drawbacks of this service are that the administrator console is flash based, and there can be delays between policies being submitted, and then taking effect. However, this is an easy to use service, which does offer strong threat protection.

Hornet is a good option for organizations that require a solution where data is not stored in the USA. Outside of Germany & Spain, the service is sold mostly through distributors and resellers who are able to provide in-country support. The low cost and ease of use this service means that it’s well suited to small and mid-sized businesses looking for easy to manage security. The service is also popular with MSPs as the service can be white labelled.

"Low cost spam filter with some bugs and quirks"

What did you like best when using this solution?

Ability to see what emails had been rejected by greylisting. Logs of the last 90-days email. Effective spam filtering. Ability to stop mass marketing emails, i.e. newsletters.

What did you dislike about using this solution?

Elements of the system still use flash. Come on Hornet, this is 2019. Flash will soon be unsupported.

Once we had a compromised mail box that started spamming out. Hornet detected it and then blocked all outbound email from our server. It took several calls via the Everycloud support team to get this resolved.

Describe your over overall experience with Hornetsecurity. Did you find this product solved your business needs?

The Hornet service is low cost and effective. The interface is a mashup of an HTML5 control panel with an older flash control panel still used for some administrative elements. Any changes to the mail routing can take up to an hour to take effect. Sometimes the Hornet data centers go offline, resulting in emails queuing for delivery. Issues with ATP wrongly blocking genuine websites.
