What are Email Security Gateways?

Email Security Gateways, or Secure Email Gateways, provide predelivery protection by blocking email based threats before they reach a mail server, whether on-premise or on Office 365 / G Suite. They protect businesses from spam, viruses, malware and denial of service attacks. The gateway scans all incoming and outbound email communications, including attachments and URLs for signs of malicious or harmful content.

What is Post-Delivery Protection?

Post-Delivery Protection platforms are made up of a range of email security products that tackle advanced social engineering threats such as phishing, spear-phishing and business email compromise. The technical term for these platforms is ‘Post-Delivery Protection.’ This is because they work after an email has been delivered, within the email network. These products are also capable of scanning internal email communications. These products often work alongside a Secure Email Gateway to add another layer of security to a network.

What is Outbound Email Security?

Outbound Email Security platforms are a new type of email security product that aims to help businesses protect their data from misaddressed email sending. Data breaches can cause huge issues for businesses of all sizes. If business data is not secure, they can run the risk of financial loss from crime, financial penalties from legal cases and loss of reputation. One major way businesses can experience data breaches is from employees sharing sensitive information, either from lack of knowledge, in error, or on purpose. Outbound Email Security platforms aim to block this from taking place.
