Awareness training helps but cannot keep up as attacks grow more sophisticated. The technical control that closes the gap is real-time link click protection. DuoCircle scans every URL in incoming and delivered email against six URL reputation databases, and re-checks at click time so attackers cannot use the bait-and-switch technique of swapping clean content for a malicious payload after delivery. Incoming messages are also scanned for impersonation and social engineering signals that indicate wire fraud or data leak attempts.

By relying on the misplaced trust of users, phishing, spear-fishing, and whaling attacks gain access to confidential data: users click a link, open an attachment from a “_trusted source_,” respond to a social engineering attempt, or are otherwise tricked into revealing such information. In extreme cases, money may be wired to a bogus expense or vendor account. Often the attack is successful because it appears to come from someone the employee places a high degree of trust in: a corporate executive or someone from the legal or audit departments, or a known vendor for example. Another factor at play is that these attacks can be among the most difficult to identify. Training employees in fraud-spotting techniques is somewhat helpful, but as employees grow smarter, attacks grow correspondingly more devious and cunning. Solutions must be found to mitigate the risk of these types of [phishing prevention](/phishing-protection/ransomware-attacks-your-organizations-ability-to-function/) attacks. A business’s confidential information is worth potentially millions of dollars to anyone who can acquire it unscrupulously, and bears at least an equivalent cost to an organization that suffers that information’s loss. [![Phishing Attacks](https://media.mailhop.org/duocircle/images/2018/07/sendgrid-alternative-7744.jpg)](https://media.mailhop.org/duocircle/images/2018/07/sendgrid-alternative-7744.jpg) ### DuoCircle Defends Against Phishing Attacks **[Ransomware](/phishing-protection/are-you-ready-to-meet-the-threat-of-locky-ransomware/), Cryptolocker and Phishing scheme authors use many techniques. One of the most effective is to send an email from a trusted domain or a URL**. When the emails are delivered to your mail server the site appears clean, but within a few hours the safe content of the site is swapped for content with a harmful payload. In this way, the first line of defense is penetrated: by the time the attack commences, your spam and virus filters have already “cleared” the site, which can then try to infect your organization’s network. [Ransomware](/phishing-protection/7-ways-protect-organization-email-based-ransomware-attacks/) can encrypt an entire network and shut down corporations in seconds by locking users’ devices. It’s an extremely effective way to infect a corporate network. DuoCircle’s Link Click [phishing protection](/phishing-protection/ransomware-attacks-your-organizations-ability-to-function/) scans the most up-to-date protection feeds to provide click protection for users, and also helps with [office 365 phishing protection](/phishing-protection/is-your-office-365-email-solution-prepared-for-phishing-threats/). When a user clicks an unsafe link, they are prompted with a warning. DuoCircle checks and validates every link clicked against six separate online URL reputation databases. _We check multiple URL reputation databases on each click for real time link checking and validation:_ - Every URL is scanned in both incoming and delivered email. Potential risks are identified before they are opened in the user’s browser. - Incoming email is scanned to identify potential impersonation and social engineering based attacks that might lead employees to make wire transfers or inadvertently leak information.
