Ransomware Prevention

Prevent Ransomware Attacks

40% of ransomware attacks involve a phishing email. Using behavioral intelligence modeling, powered by machine learning, Tessian detects and prevents email-based ransomware attacks.



Attacks On The Rise

40% of Ransomware Attacks Start as a Phishing Email


Phishing attacks, the leading delivery vehicle for ransomware, are on the rise. Why? Cybercriminals know that they can craft messages that bypass legacy email security solutions and evade detection.


Most legacy phishing tools largely rely on a rule based approach, as well as on a threat intelligence engine, consisting of previously known attack signatures to detect phishing attacks. As a result, organizations learn about these attacks when it’s too late – usually after the compromise has occurred.




Know Your Risks

Detecting Ransomware is Difficult


Detecting and preventing ransomware is extremely difficult because:


  • There can be multiple threat vectors attacking the organization and in several different ways, making the chances of a successful ransomware attack higher,
  • Email is a delivery mechanism of choice for ransomware and phishing attacks have become increasingly sophisticated. CryptoLocker, NotPetya, Locky and TeslaCrypt are some famous examples where phishing was used as a means to deliver a ransomware payload.
  • Legacy, rule-based email security solutions leave organizations unequipped to deal with these advanced threats.

How Tessian Intelligently Prevents Ransomware

  • Automatically Detect and Prevent Ransomware via Email
    Unlike legacy solutions that scan for known threats and rely on rules, Tessian uses a behavioral approach. Leveraging Behavioral Intelligence modeling powered by machine learning, Tessian creates relationship graphs and baselines for what is normal for each end user.
  • Quickly Detect, Mitigate, and Remediate Threats
    SOC teams can readily view top threats, most targeted end users, and detailed breakdown of anomalous events detected by Tessian. 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.
  • Enhance your SOC Workflows
    Quantify risks, compare trends, and influence key stakeholders with automated reports that clearly outline threats detected and prevented. Benchmark your risk against industry peers, and automate SOC workflows with your SIEM, SOAR, IAM, ITSM, SEG or Phishing Training vendor to enhance security insights and orchestrate workflows.
  • Educate End-Users on Advanced Email Threats
    Makes phishing awareness training stick by alerting end users to threats in-the-moment with contextual warnings that help them spot threats in the future. Low false positive rates mean when they see an alert, they pay attention. Tessian delivers frictionless employee education with contextual, in-the-moment alerts. Powerful, yet non-intrusive end-user education helps organizations build stronger security cultures and reduce risks over time.
