Email Security: Microsoft Defender for Office 365

Your inbox is the most targeted entry point in your business. Tower Digital’s FortressONE email security solution makes sure what lands there has already been cleared.

Stop Email Threats Before Your Team Ever Sees Them With FortressONE

Phishing, impersonation attacks, and malware-laced attachments are the number one way attackers get into small business environments. Tower Digital has been protecting Dallas–Fort Worth businesses since 1999, and that protection starts with Microsoft Defender for Office 365 built directly into FortressONE. Starting at $39 per user, you get AI-powered email security that identifies and blocks threats traditional filters completely miss.

  • AI-Powered Phishing and Malware Detection

    FortressONE email security uses advanced AI to identify malicious emails the moment they arrive, catching phishing campaigns and weaponized attachments that standard filters let through every day.

  • Sentiment Analysis to Catch Impersonation and Phishing Attempts

    Language model-based analysis reads the intent behind every message, flagging impersonation attempts and business email compromise attacks that look legitimate on the surface.

  • Protection Against Zero-Day Malware in Attachments

    Microsoft Defender for Office 365 detonates suspicious attachments in a secure environment before they reach your team, stopping threats that have never been seen before.

Make Your Team the First Line of Defense

Attackers spend more time crafting convincing emails than you might think, because getting one person to click is all it takes. Microsoft Defender for Office 365 pairs with Tower Digital’s continuous employee training that keeps your team sharp against the latest techniques.

  • Simulated phishing attacks train your team to recognize and report real threats before they cause damage.
  • Targeted education keeps your employees current on the exact techniques attackers are using against businesses like yours right now.
  • Employee resilience reporting tracks progress across your team so you always know where awareness is strong and where it still needs work.
  • Continuous training evolves alongside the threat landscape, so your team never falls behind the attacks targeting them.
