Benefits of a Cloud Email Security Gateway

With the ever-increasing volume of malicious emails hitting organisations each day your organisation is at risk to a multitude of threats. With our service, you can drastically reduce that risk before malicious emails land in your client mailboxes making your life so much easier and your organisation safer.

CEO Fraud and Phishing Detection

Being a cloud-based email security service information is received in real-time giving you instant knowledge of new phishing attacks and tactics.

Reputation Analysis

All new domains and IP’s build a reputation based on their behaviour. In our email security service, this reputation is distilled from knowledge based on traffic across the entire range and applied in real-time. This gives you the opportunity to prevent attacks before they happen.

Normal Traffic Visualisation

Our service shares data from around the world giving you a clear view of what is normal traffic and what is suspicious traffic.

Real-Time Malware & Ransomware Detection

All incoming emails are examined prior to being downloaded reducing your vulnerability. The service uses multi-layered filtering to ensure that incoming emails are safe before it reaches an employee’s mailbox.

Threat Intelligence

Using Hornetsecurity's unique combination of in-house developed tools such as real-time blacklists, AS rankings, passive DNS, and more stops Ransomware, Phishing and other dangerous attacks before they reach your organisation

Marketing and Graymail Classification

Graymail, which includes newsletters and marketing emails, can be set to quarantine as per your policy. In many cases, these emails will be unwanted, but come from genuine senders with a trustworthy reputation. Graymail Management differentiates these emails from genuine spam and allows for admins and end-users (optional) to decide what newsletters they want to receive, while keeping unwanted communications from these bulk senders out of their mailbox, making employees more productive.

Signature Based 

Each email that passes through Hornetsecurity's protection system is scanned by five separate anti-virus engines. Three of these are signature-based, while the other two are behavioural-based engines to ensure the system captures new viruses and malware, these are also continuously changing to take advantage of the best performing engine.

Content Filtering

Emails are scanned for suspicious content and attachment types such as .pdf, .exe, .js, etc, that are often linked with malicious attacks. Content that appears to be dangerous or spam will be scored and either be quarantined or discarded, depending on its risk.

Connection Filtering

The service includes a variety of tests and checks to rate each connection and identify it if it seems to authenticate or not, including IP reputations, if the domain exists in DNS, domain SPF and other filters

Multi-Layered Encryption

The service ensures complete protection, multiple layers of encryption secure clients, including opportunistic TLS encryption. PDF encryption and secure portal encryption are also offered as an additional service if you require them
