Representing over 50% of all email traffic, spam is the most intrusive method cyber criminals use to introduce malware and viruses into corporate systems. But in additon to the danger of infection with ransomware, spyware or a cryptominer, important workflows can also be interrupted by the annoying flood of unwanted spam emails.
Assisternet Email Spam Filter and Malware Protection Service offers the highest detection rates on the market, with 99.9% guaranteed spam detection and 99.99% virus detection. Our Spam Filtering Service effectively protects mail servers against DDoS attacks and phishing emails. Our multi-layered spam filtering service blocks the majority of spam emails as they arrive—keeping the quarantine clear and easy to manage. With proven features and thorough spam filtering mechanisms, your inbox remains free of annoying spam emails.
The abbreviation DDoS stands for Distributed Denial Of Service. A DDoS attack is a type of DoS attack in which multiple hijacked systems are used to overload system resources or network bandwidths. This makes websites and online services unreachable. For companies, this often means large financial losses due to delivery bottlenecks, for example, and major damage to their image from the perspective of customers.
DoS attacks are intercepted by Hornetsecurity’s Hosted Spam Filtering and Malware Protection long before they reach the customer’s network. Parallel infrastructure distributed across multiple data centers and intelligent protection mechanisms ensure that authorized mail traffic continues to flow even in the face of massive waves of spam emails and DDoS attacks.
A phishing attack is a digital identity theft. Hackers send fraudulent emails which, for example, imitate the look of well-known online service providers such as Amazon or PayPal or of well-known banks. If the personal data requested is entered on the phishing website, it is sent directly to the cyber criminals.
With the help of link tracking and other techniques, the spam filter service effectively protects users from phishing emails. Among other things, reloadable malicious script commands are detected. This enables detection of dangerous drive-by downloads, for example.

Newsletters that are not classified as spam and other infomails that unnecessarily interrupt your workflow are filtered out and kept for later retrieval. They are listed in the individual Quarantine Report and can be delivered from there if required by mouse click and whitelists.
Encryption of the transmission path between mail processing systems of Hornetsecurity and the customer’s email system via TLS. Prevents third parties from spying on email data during transmission.
Incoming and outgoing emails are automatically scanned for malicious URLs. This prevents a user from clicking on a link to an infected page or downloading malware, or from accidentally forwarding malicious links.

The virus filters are constantly updated and always current. Our own scanner, which specializes in viruses spread by email, is used among other things.
Outgoing emails are also checked for spam and viruses to prevent the unintentional distribution of malware and spam emails.
Bounce mail is the term used to describe messages automatically generated by mail servers that inform you about the absence of users or delays in delivery of emails, for example. Real bounces are useful. But bounces that reach a user because sender addresses have been forged are a problem. Hornetsecurity Bounce Management ensures that only genuine bounces reach the recipient in incoming mail traffic. Bounces in response to spam with fake sender addresses are reliably filtered out. Provides reliable protection against backscatter and bounce attacks.
New and previously unknown viruses are stopped by the early warning system. Hornetsecurity continuously analyzes incoming mails to so-called honeypot accounts (email addresses that are only intended to receive spam) for unusual attachments, links, senders or content. Derivation of signatures from this occurs within a very short response time (usually <5 minutes).
In addition to spam blocking, incoming emails must pass through multiple filter stages before they are either recognized as authetic emails and delivered to the customer’s mail server or placed in quarantine. The user can view quarantined messages through the Quarantine Report or on the control panel. Guaranteed 99.9% spam detection, less than 0.00015 false positives per clean mail, and 99.99% virus detection guaranteed by 18 independent virus and phishing spam filters.
Create specific rules for automated application to inbound and outbound email.
Unwanted attachments can be rejected or quarantined. Adjustable content filter for unwanted attachments, protection against malware and enforcement of company policies. Adjustable size limitation of emails protects against impairment of the mail server and mail traffic due to excessive data volume.
Logins and changes to the control panel are logged indelibly and can be viewed by administrators.
The “Service Level Agreement” (SLA) describes the performance characteristics of the service, among other things. The scope of services such as the filter performance and the availability of the service is defined in the service description.
The majority of spam emails are rejected at the blocking stage. The remaining emails move on to active analysis, where the email stream is cleaned by a variety of filter rules.
The quarantine allows the user to check individual emails for which the classification is unclear.
Set up a domain, adjust basic settings to individual requirements if desired, set up MX records—done. The conversion to Hornetsecurity Spam and Malware Protection is completed in a few minutes. By connecting to the company’s own directory service (LDAP / AD), user data can also be synchronized automatically.
Are your employees’ mailboxes distributed over different mail servers but all using the same mail domain? No problem! With Hornetsecurity Advanced Routing, mails are automatically routed to the various mail servers of subsidiaries, locations, etc. Adjustable for users, groups or domains.
Via the control panel, the email footers of all employees can be maintained from a central location. This makes it easy to ensure the inclusion of mandatory information in business letters or to integrate current information for customers.
With just one mouse click, other Hornetsecurity services can be added (email encryption, Email Archive or the Continuity Service). The service grows in concert with the needs of the customer.
Users can tailor the delivery of their Quarantine Reports to their way of working and schedule them at specific times—even several times a day.
Emails in quarantine can be delivered from the spam report with a simple mouse click, regardless of whether they are alleged spam messages or infomails.
The vast majority of all spam emails are blocked directly, so the quarantine and thus the spam report are kept very small. This gives the user a quick overview of current emails in quarantine.
Hornetsecurity ensures the emails you want reach their destination intact. And if our customer’s mail server is unavailable, incoming emails are stored for up to 7 days.
Large portions of email traffic are unwanted and put unnecessary strain on the mail server. The Hornetsecurity spam filter only lets valid messages through, which significantly increases the performance of the customer’s mail server. The integrated virus filter makes an additional protection system superfluous.
The number of authentic emails accidentally classified as spam is less than 0.00015—so out of one million emails scanned, a maximum of four are falsely classified as spam and quarantined.
Because of the high number of pre-blocked emails, the number of remaining spams in quarantine is small and manageable. If there is a false positive email, it can be found quickly in the clearly understandable spam report.
