    ScanMail

    ScanMail

    Trend Micro

    More than 90 percent of targeted attacks begin with a spear phishing email, which means your mail server security is more important than ever. Unfortunately, most mail server security solutions, including the limited set of built-in protections in Microsoft® Exchange™ 2013 and 2016, rely on pattern file updates, which only detect traditional malware. They don’t include specific protections to detect malicious URLs or document exploits commonly used in targeted attacks or advanced persistent threats (APTs). ScanMail™ Suite for Microsoft® Exchange™ stops highly targeted email attacks and spear phishing by using document exploit detection, enhanced web reputation, and sandboxing as part of a custom APT defense, protection you don’t get with other solutions. In addition, only ScanMail blocks traditional malware with email, file, and web reputation technology and correlated global threat intelligence from Trend Micro™ Smart Protection Network™ cloud-based security.

    See how Omniquad’s Cloud based IT security services can meet all your online security needs. Email filtering, web filtering, archiving, data loss prevention, and more. Today email security goes beyond just protecting the organization against virus and spam. Email has become one of the key delivery mechanisms for cyber threats. Cybersecurity is not just an IT issue, it is a business risk. To tackle this risk a wide angle or a cross-functional approach is necessary. Bearing in mind that the delivery mechanism for a large segment of cyber-threats is quite simple and not very technical the solution needs to combine the social with the technical. Key factors are typically clicking links in emails, opening attachments with malicious code, carelessly downloading programs, or having weak passwords. Most of this can be addressed by a comprehensive email security solution, which makes the combination of Office 365 with Mailwall Cloud very powerful.
