Sendio's E-mail Security Platform Technology Overview

Workflow
Sendio's ESP is a sophisticated state machine that implements a highly configurable workflow engine. On both the inbound and outbound path the Administrator can configure specific policy and system behavior for each stage in the workflow.

Sender Check
The system does a series of tests using the Domain Name Service (DNS) and other mechanisms to identify and classify the original sender of a message.

Recipient Check
The system verifies that the intended recipients of a message have accounts on the target e-mail server.

SilverListing
The system uses a series of low-level SMTP tests to determine the validity of the sending e-mail server.

Anti-Virus / "Malware"
The system scans all messages to ensure that they do not contain viruses, trojans, bots or other "malware".

• Corporate Policy - the system implements policies for handling large messages, those with "untrusted" attachments, or with an excessive number of recipients

Standards Policy
Messages are checked against industry standards for sender authentication, such as DKIM and SPF.

Contacts Check / SAV
Messages are checked against both system and individual user Accept-Lists, Hold-Lists and Drop-Lists, and may be processed using Sender Address Verification (SAV).

Ease of Use
The Sendio focus is on Ease of Use and eliminating on-going administration. As such, we have integrated as much automation as possible.

• Auto-update - New maintenance releases and services updates can be set to an automated download schedule minimizing involvement by the administrator
• Easy implementation – Robust hierarchical management system allows for manageable rollout of the complete e-mail security suite of services across your organization
• Seamless Directory Integration – No matter which directory services your organization is using, your directory can be seamlessly synchronized with the ESP, providing a continuously up-to-date listing of protected accounts.

Full diagnostic suite
Sendio's ESP contains a full cadre of diagnostic tools to accurately test your e-mail network infrastructure prior to deployment and for advanced troubleshooting.
