More and more organizations are training their employees to identify fraudulent emails, but judging by the 270 percent increase in phishing incidents that the FBI has recorded since 2015, the effort isn’t nearly as effective as it could be. So CSOs are now turning to automated scam prevention providers like Agari Inc., which raised $22 million in funding this week to capitalize on the trend.

The capital will enable the startup to step up customer acquisition efforts and enhance the capabilities of its namesake phishing prevention system. The Agari Email Trust Platform is a cloud-based analytics engine that scans some 10 billion messages every day to identify new attack methods, malicious domains and scanners. After stumbling across a previously unknown threat, the service makes it discovery available through the startup’s two commercial offerings, which enable organizations to harness the information in their security efforts.

The first solution is called Agari Enterprise Protect and focuses on blocking phishing attacks that target internal company assets. According to startup’s website, the software employs machine learning algorithms to compare every message against the Agari Email Trust Platform’s threat database for signs of foul play. The analysis produces a risk score that is used to determine whether an email should be allowed to reach its intended recipient, or diverted to a special inbox reserved for malicious items.

From there, security professionals are able to trace fraudulent emails back to the source using Agari’s other product, Customer Protect. As the name implies, the software is designed to combat not only attacks that target a company’s workers but also attempts to scam its clients. Such campaigns can cause a tremendous amount of brand damage that has the potential to cost just as much as an employee accidentally sharing confidential information with a hacker. The startup’s ability to combat both threats at the same time has predictably garnered a lot of interest in the corporate world.

Agari claims that over 100 organizations currently use its software to combat spear-phishing, including six of the world’s top 10 banks and five of the largest social media networks. Yet CEO Pat Peterson revealed in an interview that it was still a challenge for his firm to secure capital due to today’s tough investment climate. “The trepidation and ghosts of previous investments were in the room” for its backers during the funding negotiations, he told Fortune. “I could tell it was scary time for them.”
