DuoCircle's Phishing Protection shields your team from malicious links and fake emails in real time — so one wrong click doesn't become your next data breach.
Human error accounts for 60% of data breaches, according to the 2025 Verizon Data Breach Investigation Report. DuoCircle's Phishing Protection is engineered to close that gap — keeping your employees shielded even when they're moving fast and not watching closely.
Every link inside an email is checked against multiple URL reputation databases at the exact moment it's clicked — not just when the email arrives. If a site turns malicious after delivery, your team is still protected.
When an employee is about to visit a flagged or dangerous site, they receive an immediate alert before the page loads — giving them a chance to stop before damage is done.
Inbound filtering catches phishing emails, spoofed senders, and spam before they ever reach the inbox, reducing the volume of threats your employees encounter daily.
Emails and their contents are scanned for malware as part of the security pipeline, adding a critical layer of defense against payload-based attacks.
DuoCircle provides email authentication tooling to help you enforce sender legitimacy standards — making it harder for attackers to impersonate your domain or trusted senders.
Ongoing visibility into your email environment helps you detect anomalies, track threat patterns, and stay ahead of emerging attack vectors.
Traditional email security checks a link once — when the message arrives. But attackers know this. They register clean-looking domains that turn malicious hours or days later, long after the initial scan. DuoCircle's Link Click Protection closes this loophole by re-evaluating every link at the moment of every click, every time. Whether your employee clicks a link five minutes after receiving an email or five days later, DuoCircle checks that URL in real time against multiple reputation databases. If the destination has changed to something dangerous, access is blocked and an alert is triggered — automatically, without any action required from IT.
