What can you expect from a provider of email security?


Protect your incoming and outgoing email through endpoint protection. In the event of a successful attack, steps for remediation should be put in place. An email security solution should be able to stop malware and non-malware threats such as impostor email (also known as business email compromise). The solution should have filtering capability and business continuity features.

Email filtering provides real-time spam and virus filtering while blocking attacks and monitoring traffic. Messages can be approved or blocked within seconds based on sender, origin IP address, attachment size, file type, or text content. Filtering ensures that trustworthy emails are delivered with minimal delay while suspect messages are blocked or quarantined.

Imposter email

Our email security solutions are comprehensive and include the following components:

Attack blocking & connection protection

When multiple occurrences of harmful traffic is coming from a single server, our solution blocks a wide range of attacks including Directory Harvest Attacks (DHA) and denial of service attacks. Attacks are detected and blocked in real-time and the source IP address is temporarily blocked.

Spam, virus & content filtering

Email filtering can be customized to block and allow email based on sender, recipient, size, content and other factors. Viruses are blocked and users can adjust to what level spam protection is set.

Message quarantine & release

The way suspicious messages are quarantined can be customized so that logs can be kept and quarantined messages can require review before release. Users can review what messages are being flagged as spam and review quarantined messages to make sure legitimate messages are not flagged.


These are the steps we follow when implementing your email security solution:

1. Set up and configure a secure, Microsoft Azure cloud.


2. Connect email security software to Azure cloud and synchronize individual email accounts to use new email security software platform.


3. Validate email flow from email security software platform to individual email accounts.


4. Configure customized whitelists and blacklists.
