Barracuda Sentinel

Barracuda Sentinel protects your users & private data with machine learning thanks to a powerful Artificial Intelligence engine that scans for advanced threats traditional email gateways miss. This AI-based protection stops phishing & account takeover attempts dead in their tracks. Because Barracuda Sentinel integrates directly into Office 365, hidden threats that O365 can't see are dug up & removed from your mail system. Since targeted attacks often carry non-obvious malicious payload, many email security platforms miss them entirely. Barracuda Sentinel harnesses AI to outsmart, outplay, & outpace threat actors.

Sentinel As A Zero-Administration Tool

Barracuda Sentinel works silently in the background to block malicious email traffic from ever setting foot in your inbox. Sentinel and other Barracuda Email Security services even work side-by-side with any other email security platform already on your network, adding an additional layer of AI-based advanced protection to root out especially elusive threats. Management is made easy by eliminating the need to manage clunky static security rules, freeing up your IT team for other tasks.

  • Discover threats hiding in your inbox right now
  • Integrates directly with Office 365 API to detect attacks
  • Stops spearphishing attacks with web impersonation & high reputation links
  • Artificial Intelligence detects signs of malicious intent & deception
  • Prevents Business Email Compromise (BEC) attempts from ever reaching their targets

Over 95% of Office 365 mailboxes contain malicious emails that slipped past their defenses. Barracuda Sentinel discovers & removes email threats even if they've already infiltrated your system.

Barracuda Sentinel

Stop Email Spoofing & Employee Impersonation

Barracuda Sentinel automatically detects & blocks attacks that impersonate your employees by spoofing their email address. Barracuda Sentinel's AI engine detects anomalies in spoofed emails & quarantines them before they reach their intended target. Barracuda Sentinel ensures low false positives with continuous improvement of its AI precision. When one Barracuda email security customer reports a missed or false attack, the entire global Sentinel system evolves in real-time to retrain AI classifiers & threat behavior signals. That means your Barracuda Email Security is always learning.

  • Automatically gather, analyze, & visualize DMARC reports
  • Uncover anomalous patterns within email body, header, & links to stop zero-day phishing
  • Detect any type of zero-day phishing including fake sign-in pages, spoofed domains, & malicious websites
  • Recognize & quarantine emails that impersonate services such as Microsoft Outlook, Docusign, & Dropbox
  • Require zero manual rules or user setup to detect any type of attack from day one

Over 95% of Office 365 mailboxes contain malicious emails that slipped past their defenses. Barracuda Sentinel discovers & removes email threats even if they've already infiltrated your system.

Stop Account Takeover Attempts

Employee credentials are a huge target for attackers. These kinds of footholds on a small business network provide opportunities to launch more targeted persistent attacks. Barracuda Sentinel tracks IPs that exhibit suspicious behavior such as failed sign-ins & other anomalous access patterns. Automated alerting & reporting make you aware as soon as suspicious access is detected.

  • Monitor for unusual activity from unknown devices or geographic locations
  • Track both user-level & organization-wide behavior patterns
  • Automatically quarantine phishing emails that lead to account takeover
  • Detect & investigate changes to user inbox rules, which may signal a compromised account

Barracuda Sentinel lets you lock attackers out of accounts, prevent the use of compromised accounts to launch campaigns, & notify external third parties if an account on your network was used to send them a potentially malicious email. With automated DMARC reporting, you get high-level insight into which IP addresses are passing or failing DMARC, domains that are misaligned, and small businesses can improve email deliverability for their legitimate outbound traffic.


Barracuda PhishLine

Transform employees into a layer of defense on your network. Human error is by far the weakest link in the network security infrastructure outlook thanks to social engineering. Potentially devastating attacks are designed to fool employees, putting your business at risk of a breach & major data loss. Barracuda Email Security pairs with PhishLine to transform your employees into a new layer of cyber defense all their own by arming them with the knowledge, experience, & training to identify phishing, smishing, user impersonation, & other sophisticated social engineering attempts.

Test your team's readiness
