Effectiveness

Libraesva ESG comes with some data loss prevention policies set up by default and admins can build further DLP rules through regular expressions. ESG’s blacklist of phishing sites and domains is updated hourly, and its Whaling Protection List enables admins to add further impersonation checks to emails sent to or from high-value users.

The search and reporting capabilities are strong and relatively easy to navigate via the platform’s web-based console, and reports can be exported to PDF and shared via email.

The platform includes ClamAV antivirus scanning by default, and Avira and BitDefender are available as optional add-ons for additional virus scanning.

The ESG itself doesn’t contain a direct link to support documentation; the Support hyperlink at the bottom of each page directs users to their own domain. The documentation hosted on Libraesva’s website contains a knowledge base, how-to guides, and downloads to upgrades and utilities—but only for version 4.0, with no information on the new features offered in version 5.0.

Ease Of Management

Libraesva ESG takes around one hour to deploy whilst on a call with a Libraesva engineer. The same goes for deploying many domains at once.

The solution offers lots of granular configurability. This can be difficult to navigate but, once configured, the solution requires little maintenance. For Microsoft Office 365 users, Outbound mail is routed through Office 365 before being sent, meaning that DKIM and domain reputation aren’t affected.

From the web-based console, admins can customize most aspects of the ESG, including status, appliance, mail transport, content analysis, authentication and integrations. Integrations are straightforward to set up, with LDAP support and support for both IMAP and POP3 for authentication. However, some customization options are difficult to find due to the number of options available.

The user access control policies and end user self-service options allow users to control their own message logs, white and blacklists, and quarantine digest report delivery.
