What is a secure email gateway and why do you need it?

A secure email gateway scans incoming emails to protect against email-borne cyber threats such as phishing attacks, compromised business emails, malware, next-generation spam, and more. But email gateways can also scan outgoing messages to prevent sensitive data from leaving an organization.

Libraesva ESG is an Integrated Email Security Solution. We deliver advanced security for cloud-based email platforms. Email Security Gateway protects Microsoft 365 and Google Workspace using multiple layers of protection, both at the Gateway and API layers, so multiple solutions are not needed. Email threats like phishing attacks, email fraud, and BEC are stopped before reaching their target


Today’s email threats move fast, and malicious files look more and more like ordinary files. Growing businesses need predictive email security to defeat today’s threats with an eye on the future.

Libraesva ESG filters all internal emails as well as inbound and outbound email traffic to protect organizations from email-borne threats and data leaks. It provides both spam filtering and spam protection against advanced threats like phishing, malspam, business email compromise, and account takeover. We block over 99.9% of phishing and malspam attacks!

We use our own sandboxing technologies to scan all links and documents. URLsand and QuickSand quickly scan all links and documents for active code and evasive behavior. This prevents users from visiting dangerous links or receiving and opening malicious files.

Simple and easy to deploy configurations guarantee that customized email protection is in place in a matter of minutes. Depending on your needs, you have the option to run in the cloud or on-premise. Cloud instances of Libraesva ESG are the most secure in the industry thanks to our dedicated, private cloud deployments. There is no need to worry about shared environments or certificates.

Microsoft 365 and Google Workspace are the world’s most popular email systems. But their native email gateway services, like EOP and ATP, have consistently failed to protect emails, users, and organizations. Malicious attachments easily slip by. It’s no wonder why hackers target them the most!

To have the highest level of protection for Microsoft 365 and Google Workspace, ditch the native email security and implement Libraesva ESG. In addition to increasing your security posture, you can expect to reduce costs compared with native solutions. With over a 99.9% catch rate for phishing and malspam, Libraesva ESG will protect you better than any other security solution.

Most SEGs only protect at the gateway and then require separate subscriptions for threat remediation or advanced threat protection. Libraesva ESG is different, filtering email at both the Gateway and API layers. Only one subscription is necessary to handle all email threats, including spam, viruses, phishing, and more. Additional features include machine learning and artificial intelligence to detect threats in malicious emails, account takeover protection, and deep URL scanning. Our Threat Intelligence Engine aims to detect threats and secure emails. The Adaptive Trust Engine tracks all history between senders and recipients for fail-proof threat detection.

In the case where a threat arrives in the inbox, Libraesva’s Threat Remediation removes the email from a single inbox or across many inboxes for wide-reaching attacks. Admins can see if users read the remediated threat, so further action can be taken if necessary. Threats can be deleted completely from the system or moved to a secure location for further analysis.

As part of our Email Security Gateway solution, the Adaptive Trust Engine (A.T.E.) is a dynamic relationship tracking tool for email senders and recipients, all transactions are tracked and monitored to measure trust and to observe who usually communicates within your organisation.

Legacy email security products rely on outdated, inaccurate, and inadequate good/bad techniques struggling to identify more advanced threats such as business email compromise, impersonation, and spoofing attacks.

Libraesva Adaptive Trust Engine uses machine learning and historical data analysis to quickly and automatically learn the legitimate communication patterns specific to each sender and recipient, making it easy to spot the anomalous emails.
