Email Security

Block Incoming Email Threats

Combine Market-leading Software With Corserva’s Expertise

External threats penetrate your business through incoming and outgoing emails. Corserva’s enterprise email security solution prevents phishing, malware, spam, imposter email, and other forms of bad content so the organization is protected from malicious attacks and potentially risky behaviors. Corserva’s solution for email security provides unrivaled protection from viruses and other email threats. The advanced spam filtering capability accurately filters emails by examining envelope headers and structure, content, email sender reputation, images, and more, to prevent spam and malware from reaching inboxes. Outgoing email can be encrypted, and email is archived for up to 10 years.

block-icon Attack Blocking and Connection Protection When multiple occurrences of harmful traffic are coming from a single server, the Corserva solution blocks a wide range of attacks including Directory Harvest Attacks (DHA) and denial of service attacks. In real-time, attacks are detected and blocked, while the source IP address is temporarily blocked.  
filter-icon Spam, Virus, and 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 their level of spam protection.  
email-quarantine-icon Message Quarantine and Release Suspicious messages are quarantined and logged. We can configure quarantined messages to require employee review before release. Employees can review what messages are flagged as spam and inspect quarantined messages to make sure legitimate messages are not flagged.
