How Does Email Threat Protection Work?

From real-time URL scanning to BEC detection - everything your team needs to keep phishing attacks out of every inbox.

Real-Time Protection

Every inbound email is scanned in real time before it reaches your users. Malicious links, attachments, and spoofed senders are blocked instantly.

Advanced Threat Defense

Multi-layered scanning engine combines URL analysis, attachment sandboxing, and sender reputation to catch threats that basic filters miss.

Time of Click Protection

URLs are re-checked at the moment a user clicks - not just when the email arrives. Delayed attacks and weaponized links are caught in real time.

Office 365 Integration

Seamless integration with Microsoft 365 and Google Workspace. No hardware, no software to install - protection activates in minutes via MX record change.

Dashboard & Reporting

Real-time visibility into every threat blocked, every email scanned, and every policy action taken. Exportable reports for compliance and auditing.

24/7 Support

US-based support team available around the clock. Phone, email, and live chat - real humans who understand email security, not chatbots.

Frequently Asked Questions

Common questions about Phish Protection

What is Phish Protection?

Phish Protection is a cloud-based email security service that blocks phishing, business email compromise (BEC), and ransomware in real time. It sits in front of your mail server and scans every inbound message before it reaches your users, with no hardware or software to install.

How does real-time email scanning work?

Every inbound email passes through our multi-layered scanning engine before delivery. We analyze URLs, attachments, sender reputation, and message content simultaneously. Threats are quarantined instantly while clean mail is delivered without delay.

Does Phish Protection work with Office 365 and Google Workspace?

Yes. Phish Protection integrates seamlessly with Microsoft 365, Google Workspace, and any email provider that supports MX records. Setup takes about 5 minutes -- just update your MX records to route mail through our scanning infrastructure.

What is time-of-click protection?

Time-of-click protection re-checks every URL at the moment a user clicks it, not just when the email was first delivered. This catches delayed attacks where a link is safe on arrival but weaponized hours or days later.

Phish Protection starts at $32 per month for up to 10 users. Additional users are $0.99 per user per month. There are no setup fees, no contracts, and no per-email charges. Volume discounts are available for larger teams.
