Native filtering wasn't built to stop today's email attacks
Email is still the #1 way attackers get into small and mid-sized businesses. Here's where most organizations are exposed — even with Microsoft 365 or Google Workspace already in place.
BEC and phishing bypass your current filter
Attackers know exactly how to slip past Microsoft 365 and Google Workspace native filtering — and one compromised invoice email can cost more than your entire security budget.
Threats that get through sit in inboxes for days
Without automated post-delivery remediation, a single malicious email can sit in dozens of inboxes, get forwarded, and spread before anyone notices.
Nobody owns DMARC, so your domain stays spoofable
Most SMBs never move past a DMARC "none" policy because enforcement is confusing and risky to configure alone — leaving your brand open to impersonation.
You find out about an attack after the damage is done
Without dedicated incident response, you're relying on an employee to report a suspicious email before anyone acts — and by then it's often too late.
Spam filtering plus four layers of protection, fully managed by Iron Cove
Barracuda Email Protection combines enterprise-grade spam filtering, threat prevention, post-delivery incident response, and DMARC authentication — and Iron Cove configures, tunes, and monitors every layer for you.
Spam Filter & Email Gateway Defense
Cloud-based spam filtering blocks junk, malware, ransomware, phishing, and denial-of-service attacks before they reach your inbox — with real-time attachment sandboxing and link protection against typosquatting.
Automated Incident Response
Post-delivery threats are automatically removed from every inbox they reached. Search, create incidents, and remediate across your organization in minutes, not days.
Impersonation & Domain Fraud (DMARC)
AI-driven detection of business email compromise and account takeover, paired with managed DMARC setup and enforcement to stop domain spoofing and brand hijacking.
Cloud-to-Cloud Backup
Unlimited, cloud-native backup and point-in-time recovery for Exchange Online, SharePoint, OneDrive, and Teams — protecting against accidental and malicious deletion.
Barracuda email security plans for the coverage level that fits your risk
Every Barracuda email plan includes prevention, detection, post-delivery response, and DMARC/email authentication. Individual components can also be purchased standalone or as an add-on.

Common questions about managed Barracuda email protection
Still deciding on the right Barracuda plan or migration path? Here's what clients ask most.
What does Barracuda Email Protection defend against?
What is the difference between Barracuda email Advanced, Premium, and Premium Plus?
Advanced covers core gateway defense and account takeover protection. Premium adds DMARC domain fraud protection, threat hunting, and SIEM/SOAR/XDR integration. Premium Plus adds cloud archiving, cloud-to-cloud backup, attack simulation, and security awareness training.
Does Iron Cove manage DMARC setup and enforcement?
Yes. We configure DMARC authentication, analyze reports, and move your domain to enforcement to stop spoofing without breaking legitimate mail flow.
How fast can Barracuda email be deployed?
Barracuda Email Protection is fully cloud-delivered with no hardware or software to install. Iron Cove typically completes deployment and tuning within a few business days.
Will Barracuda email work with our existing email server?
Yes — Barracuda Email Protection layers on top of Microsoft Exchange Online Protection, Google Workspace, or other gateways without conflicting with existing rules.
What happens if a threat still reaches someone's inbox?
Automated Incident Response removes malicious emails from every inbox they reached post-delivery, alerts affected users, and blocks the sending domain — typically within minutes.
Why do Microsoft 365 businesses need a third-party spam filter?
Microsoft 365's built-in Exchange Online Protection catches commodity spam, but it regularly misses business email compromise, spear phishing, and zero-day malware. Barracuda adds a second layer of AI-driven spam filtering, sandboxing, and post-delivery remediation that EOP alone doesn't provide — closing the gap attackers actively exploit.
Is Barracuda the best spam filter for Office 365?
Barracuda is consistently rated among the top third-party spam filters for Office 365. It integrates directly via API (no MX record change required), filters spam and phishing more aggressively than native EOP, and adds account takeover detection and DMARC enforcement that Microsoft doesn't include out of the box. Iron Cove manages the entire deployment for you.
Does Barracuda work as a spam filter for Gmail and Google Workspace?
Yes — Barracuda Email Protection integrates directly with Google Workspace via API, adding enterprise spam filtering, phishing detection, and automated incident response on top of Google's native filters. If your team uses Gmail for business, Barracuda catches the threats Google's filters regularly miss, including spear phishing and business email compromise targeting your domain.
My Microsoft 365 users are getting spam emails — what should I do?
Microsoft 365's Exchange Online Protection only catches known threats. Sophisticated spam, BEC, and spear phishing regularly slip through. A third-party spam filter like Barracuda adds an AI-driven layer that re-scans all mail, sandboxes attachments, and can retroactively remove malicious emails that EOP let through. Iron Cove can typically deploy and tune Barracuda on your M365 tenant within a few business days.
