Effectively Detect and Prevent Threats Coming Into and Going Out of Corporate Inboxes: Tessian

Tessian Cloud Email Security understands behaviors to automatically prevent advanced threats and data loss on email and build a smart security culture. Security teams can no longer rely on legacy, rule-based email security solutions to keep organizations safe. Tessian uses machine learning and behavioral intelligence modeling to accurately detect and prevent advanced email threats that rule-based Secure Email Gateways and built-in security within Microsoft and Google fail to stop. Tessian detects and prevents advanced threats and data loss on email including accidental data loss, data exfiltration, and advanced phishing attacks like business email compromise, account takeover and social engineering. Inboxes are protected on desktop and on mobile. Where traditional gateway deployments take months, the Tessian API enables seamless integration for Microsoft 365 clients, whether on premise, in hybrid, or in cloud environments in minutes so you can easily consolidate your security stack. No configuration is required.

Prevent Advanced Email Attacks

The platform automatically protects against advanced email attacks, including account takeover (ATO), business email compromise (BEC), spear phishing, ransomware, and socially engineered impersonation attacks that bypass rule-based Secure Email Gateways, Microsoft 365 and Google Workspace security controls. Unlike legacy solutions that are rule-based and scan for known threats, leaving organizations vulnerable to zero-day attacks, Tessian uses a behavioral based approach. Leveraging machine learning powered behavioral intelligence modeling, Tessian establishes what normal behavior looks like for each end-user so that it can automatically detect when something looks unusual. Tessian Defender deploys in seconds, learns in hours, and protects within a day.

Predict and prevent advanced email attacks:

• Account Takeover
• Business Email Compromise (BEC)
• All Impersonation Attacks
• Spear Phishing
• Social Engineering
• Whaling Attacks

Being an Integrated Cloud Email Security (ICES) solution, Tessian analyzes emails in real-time and uses behavioral intelligence modeling to automatically detect and prevent all forms of advanced social engineering attacks. Tessian integrates with Microsoft Office 365 via API to provide a faster and easier deployment and protection. Tessian Defender now deploys in seconds, protects in hours and extends protection across any device. Automatically starts protecting without requiring email rerouting or changes to MX records. Improved protection for end-users while offering in-the-moment coaching. Tessian’s soft quarantine – or user quarantine – approach uniquely protects organizations from being compromised by an end user accidentally opening a malicious attachment or clicking a URL before they’ve had an opportunity to determine the email safe. Emails with the highest probability of being malicious are automatically quarantined for inspection by the security admin. For emails with a lower probability of being malicious, Tessian warns end-users of the potential threat in-the-moment, clearly explaining why the threat was flagged and advice on what action to take via contextual warning messages. Low-false positive rates means alerts are non-disruptive to people’s workflows.

This real-time intervention helps reduce security teams’ workloads as employee self-remediate threats and it builds smarter security cultures, as click-through rates trend down and people become better at spotting threats on email over time. SOC teams can readily view top threats, most targeted end users, and detailed breakdown of anomalous events detected by Tessian Defender. And, with robust remediation tools, admins can quarantine, clawback unsafe emails from people’s inboxes, or update blocklists to prevent similar threats with a single click.

Teams can future proof defenses using shared threat intelligence and automatically block deny-listed domains across the Tessian ecosystem – no rules required. With Tessian, you can also benchmark impersonation risk levels against industry peers.

Tessian Cloud Email Security Platform

Automatically detect and prevent accidental data loss caused by people sending emails to the wrong recipient or attaching the wrong files. Tessian analyzes historical email data to understand content, context and communication patterns, enabling a comprehensive mapping of each and every employee’s normal behavior and email relationships (both within and outside your organization). Behavioral intelligence models are established and become more effective with each threat detected. All emails leaving employee inboxes are analyzed in real-time. Using machine learning powered behavioral intelligence modeling, Tessian conducts an inspection of email content and attachments and automatically detects anomalous events that indicate accidental data loss.

As misdirected emails and incorrect attachments are detected, end-users are alerted in real-time with clear, simple explanations and intelligent suggestions for alternative recipients. End-users are empowered to correct their mistakes before the email is sent. With Tessian Cloud Email Security Platform, remediating and reporting on email security risks is easy. Warnings and employee interactions with those warnings are logged for inspection so you can create targeted policies or take other proactive and preventative action. Generate automated reports to share insights with other departments or the board.

Tessian analyzes historical email data to understand content, context, and communication patterns, enabling a comprehensive mapping of every employee’s business and non-business email contacts. Behavior Intelligence models are established and become more effective with each threat detected. Tessian analyzes all outbound emails in real-time for sensitive data exfiltration. It uses machine learning-powered behavioral intelligence modeling to automatically detect anomalous data loss events that indicate negligent and malicious data exfiltration. End-users receive warnings in real-time, when data exfiltration threats are detected. Warning triggers can be tailored to suit your company’s security policies and workflow requirements; people are warned, emails can be blocked, or activity can be silently tracked. Seamlessly access security events detected and prevented and have automated reports delivered – making remediating and reporting on risks easy.
