    ScanMail Reviews
    Over 90% of targeted cyber attacks initiate through spear phishing emails, highlighting the critical need for robust mail server security. Sadly, many existing mail server security measures, like the basic built-in defenses available in Microsoft® Exchange™ 2013 and 2016, depend on outdated pattern file updates that primarily identify conventional malware. Such measures typically lack the necessary capabilities to recognize harmful URLs or document exploits that are frequently employed in targeted attacks and advanced persistent threats (APTs). In contrast, ScanMail™ Suite for Microsoft® Exchange™ effectively mitigates highly targeted email threats and spear phishing attempts by incorporating document exploit detection, improved web reputation, and sandboxing as part of a tailored APT defense strategy, advantages not provided by competing solutions. Moreover, ScanMail uniquely offers the ability to block traditional malware through advanced email, file, and web reputation technologies, along with correlated global threat intelligence sourced from Trend Micro™ Smart Protection Network™ cloud-based security, ensuring comprehensive protection for your mail server. Ultimately, choosing the right security solution is vital in safeguarding your organization against evolving cyber threats.

    GBS iQ.Suite Reviews
    The adoption of collaboration tools and meeting platforms from providers like Microsoft and CISCO is on the rise, leading to an urgent need for enhanced security measures. As organizations expand their communication channels and navigate increasingly intricate IT infrastructures, many of these platforms are now fully cloud-based, resulting in the emergence of new gateways and potential attack vectors. Although most businesses are diligently enhancing their email security protocols, they frequently neglect to safeguard against harmful files that can infiltrate their systems through platforms like SharePoint or messaging apps. Current security solutions are often inadequate and fail to provide comprehensive protection. To effectively address these challenges, the platforms offer a centralized cloud solution that enables companies—regardless of size—to swiftly adapt to the evolving threat landscape and bolster their defenses against emerging risks. This approach not only enhances security but also fosters a more resilient operational environment.
