Stop phishing and impersonation before it reaches your inbox
Managed email security for Microsoft 365 and Google Workspace — threat filtering, BEC protection, encryption and training, set up and run by US-based engineers.
What we stop at the gateway
- ✓Impersonation & BEC detection
- ✓Attachment sandboxing & URL rewriting
- ✓SPF, DKIM & DMARC enforcement
- ✓Encryption, training & archiving
Email is still how most attacks start
Attackers don’t need to break your firewall when they can just ask an employee to click, pay or log in. Sound familiar?
Phishing keeps getting through
Your team still gets fake invoices, password-reset lures and “quick favor” emails that look real. One click is all it takes.
Someone is impersonating your CEO
Lookalike domains and spoofed display names trick finance into wiring money or changing payroll details.
Default filtering isn’t built for targeted attacks
Microsoft 365 and Google Workspace catch bulk spam, but business email compromise and zero-day links slip past the defaults.
Nobody owns email security
Quarantine reviews, DMARC reports and user complaints land on whoever has time — which means nobody.
Email security for Microsoft 365 and Google Workspace
Whichever platform you run — or both, mid-migration — we layer protection on top without changing how your team works.
Microsoft 365 email security
Go beyond Exchange Online Protection with impersonation detection, URL sandboxing and continuity. We configure connectors, transport rules and Defender settings so nothing bypasses the filter.
- • Exchange Online connector lockdown
- • Defender for Office 365 policy tuning
- • Proofpoint or Barracuda in front of Exchange
Google Workspace email security
Gmail’s filters are strong for consumer spam, but businesses need inbound gateways, compliance rules and admin controls tuned for targeted attacks.
- • Inbound gateway and routing setup
- • Gmail advanced safety settings hardened
- • Proofpoint or Barracuda in front of Gmail
Complete protection, fully managed
We deploy and manage the layers your business actually needs — and skip the ones it doesn’t.
Advanced threat filtering
Multi-layer spam, malware and ransomware filtering in front of your inbox, with attachment sandboxing and malicious URL rewriting.
Impersonation & BEC protection
Detect display-name spoofing, lookalike domains and executive impersonation before finance or HR acts on it.
SPF, DKIM & DMARC
We publish and monitor your authentication records so attackers can’t send mail as your domain — and your own mail stops landing in spam.
Email encryption & DLP
Policy-based encryption for sensitive data like financial, legal and health information, with no extra steps for your users.
Security awareness training
Simulated phishing and short training modules so your people become a layer of defense instead of the weak link.
Continuity & archiving
Keep email flowing during outages and retain a searchable archive for compliance and eDiscovery.
From exposed to protected without downtime
A staged rollout means your mail keeps flowing while we tighten things up.
Risk review
We review your tenant, MX and DNS records, current filtering and recent threats to find the gaps.
Plan & recommend
You get a clear recommendation — Proofpoint Essentials, Barracuda or native hardening — with per-user pricing.
Staged deployment
We configure policies, pilot with a small group, then cut over MX records with a rollback path ready.
Ongoing management
US-based engineers tune policies, release quarantined mail, monitor DMARC and handle user requests.

Email security questions, answered
The questions we hear most from business owners and IT leads.
Isn’t the security built into Microsoft 365 or Google Workspace enough?
The built-in filtering catches bulk spam and known malware, but targeted phishing, lookalike domains and business email compromise regularly get through. A dedicated email security layer such as Proofpoint Essentials or Barracuda adds impersonation detection, URL rewriting, attachment sandboxing and continuity that the default tenant settings do not provide.
Will adding email security disrupt mail flow?
No. We stage the change, test with a pilot group, then cut MX records over during a low-traffic window. Most customers see no interruption, and we keep a rollback path ready until mail flow is verified.
Do you support both Microsoft 365 and Google Workspace?
Yes. We configure email security for Microsoft 365 / Exchange Online and for Google Workspace / Gmail, including mixed environments during a migration.
Do I have to sign a long-term contract?
No. Iron Cove works without long-term contracts. You stay because the protection works and the support is responsive.
What does email security cost?
Pricing depends on the platform and plan you choose and the number of users. We will recommend the right tier for your risk profile and give you a clear per-user price before anything is deployed.
