Prevent, detect, and remediate account takeover.
Hackers use compromised accounts to move laterally within your organization and attack your customers and business partners.
Protect your business and employees from account takeover attempts and attacks launched from compromised accounts.
Identify behavioral, content, and link-forwarding anomalies within your organization to flag and quarantine fraudulent emails sent from compromised accounts.
Get access to remediation tools to quickly block attackers’ access to compromised accounts and restore access for legitimate users.
Corporate account takeover presents a significant new threat to businesses. Hackers gain access to corporate email accounts through stolen credentials and use them to launch subsequent targeted attacks, internally and against external targets. Account takeover or attacks that originate from these accounts are almost impossible to detect since they don’t leverage impersonation techniques — they come from a legitimate account and appear to be from a trusted source. In fact, traditional email security solutions don’t even observe internal traffic and have no way of stopping an attack originating internally.
Prevent loss of credentials by blocking targeted phishing attacks missed by email gateways.
Detect and alert IT when an account is compromised.
Remove all malicious email sent by a compromised account.
Barracuda detects both account takeover attempts and attacks launched from compromised accounts. By analyzing both historical and inbound data, the AI identifies behavioral, content, and link-forwarding anomalies within your organization to flag and quarantine fraudulent emails. It’s also able to prevent attempts to compromise employee credentials, by automatically blocking targeted phishing emails that try to harvest employee passwords.
Once an email account is compromised and hackers are inside the organization, they can start moving laterally, looking to compromise more valuable accounts. Attackers monitor and track activity to learn how your company does business and use this information to launch attacks against your partners and customers. With Barracuda, your IT team will be alerted of suspicious behavior in your users’ email accounts, including unusual log-ins, changes in inbox rules, and malicious emails sent from internal accounts.
Account takeover can be devastating for organizations and must be remediated quickly once identified. IT admins need to ensure attackers are blocked from access to compromised accounts, any malicious messages are identified, and recipients are alerted. With Barracuda’s account takeover remediation tool, admins can delete all email attacks sent internally from compromised accounts and issue alerts to any external recipients. IT teams are able to quickly lock out hackers from compromised accounts to ensure that they are no longer used with malicious intent.
Detect suspicious logins by tracking IPs that exhibit suspicious behavior, such as failed sign-ins, and share intelligence across all users and accounts. Track each user’s access patterns and alert IT administrators when Barracuda observes unusual sign-in activity such as from an unusual device or geography. The AI tracks user-level patterns and organization-wide patterns.
By detecting anomalies in internal employee communications, Barracuda can automatically detect when employee accounts become compromised and send malicious emails to internal and external recipients. Administrators get alerted when an account has been compromised, and they can take immediate action.
Barracuda automatically quarantines phishing emails that allow attackers to steal employee credentials and can lead to account takeovers.
Barracuda can automatically identify which malicious emails were sent from a compromised account and flag them for administrators.
Changes to a user’s email inbox rules can potentially indicate an account takeover. Barracuda lets IT administrators review and investigate recent changes to inbox rules. The Inbox Rules Change Feed provides visibility across the entire email environment and lets you investigate rules changes for a specific email or account.
Barracuda's account takeover remediation tool allows administrators to delete all phishing emails sent from compromised accounts from employee mailboxes.
Barracuda allows administrators to identify which external recipients received emails from compromised accounts and notify them of the attack.
Barracuda helps administrators lock out attackers from compromised accounts, preventing them from using the compromised account to launch phishing campaigns and forward emails externally.
Barracuda account takeover protection uses Office 365 APIs to connect directly to your environment. The APIs allow the AI to both learn customer historical communication patterns, as well as detect and quarantine emails in real time. It’s a cloud-based SaaS solution that requires no maintenance or installation.
You can set up Barracuda’s account takeover protection in one minute by simply signing up and connecting it to your Office 365 tenant. No need to change your MX records or install any software.
The API architecture allows impersonation protection to work alongside any existing gateway-based email security solution as a last layer of defense for targeted attacks.
