ATO threats pose an immense danger to organizations as hackers use sophisticated impersonation techniques and trusted email accounts to launch attacks that evade conventional threat detection tools. While organizations can secure their own email infrastructure, they have no control over their extended network of customers, partners, and suppliers.
Detecting attacks from trusted accounts is extremely difficult:
ATO is one of the pathways to Business Email Compromise (BEC), which is the biggest cause of email breaches globally.
Sometimes, the ATO attack chain does not end with an individual employee’s credentials being compromised. The attacker might use this account to access the email credentials of other employees within the same organization, especially the C-suite executives to execute a breach.
One of the biggest challenges before CISOs is to lower their risk exposure by building a proactive security strategy that can anticipate, identify, and prevent potential ATO attempts well ahead of an actual breach.
Most legacy email security tools largely rely on previously known attack signatures to stop threats. As a result, organizations today learn about these attacks months after they have been breached and have incurred significant damages.
Avoid ATO Breaches, Stay Compliant
Tessian tracks user behavior and detects even the most subtle anomalies that might signal an attack at the first instance of an attempt. This not only helps organizations stop breaches at a very early stage, but also avoid potential compromise to brand and business reputation along with compliance penalties.
Ensure a Rapid Response
Tessian automatically categorizes and prioritizes threats by assigning a Risk Confidence Score and displaying them within the portal for quick administrative response. Administrators can view high-level threat data as well as granular forensics for detailed analysis. Tessian also delivers real-time alerts of ATO events to dedicated mailboxes to ensure that SOC and security managers get notified without any delay.
Automate Investigation and Remediation
By automating the grouping of ATO events, Tessian allows administrators to detect and act on burst attacks quickly. Automatic creation of event logs and cases without manual intervention helps SecOps/SOC managers optimize their resource-constrained engineering teams. This also reduces noise and enables one-click remediation of multiple events and burst attacks.
Educate Your Employees
Tessian delivers frictionless employee education with contextual, in-the-moment alerts. Powerful, yet non-intrusive end-user education with alerts helps organizations drive employees towards secure email behavior to reduce risks over time.
