Since you’re reading this article, you are probably at the absolute minimum technologically savvy enough to recognize a phishing email as it hits your inbox. However, you might not be familiar with more advanced threats such as ‘spear phishing’—which is the act of using trusted senders to target your business with legitimate-seeming phishing attempts. Your end users are also likely not as technologically aware of phishing attempts, and even with education, phishing scams can still threaten your business.

One of the best methods of securing your email infrastructure is by integrating a phishing protection tool into your environment. These tools integrate with your system typically via a pre-established setup for platforms like Office 365 or Google Workspace; or through an API with flexible integration options for your custom email system.

Phishing protection tools then employ a variety of systems to prevent your end users from falling prey to phishing scams. The most fundamental function they provide is simply scanning your inbound and outbound emails for malicious content, such as predatory URLs or malware attachments. Other features might include phishing simulations, which send fake phishing scams to your end users to test their understanding of email security—a helpful tool in educating your users on the risks posed by email communication.
