    Protect your organization, executives, and brand

    The challenges of impersonation attacks

    Not all email-borne attacks use malicious URLs or attachments. Business email compromise or impersonation attacks often use social engineering and are designed to trick key users such as finance, executive assistants, and HR into making wire transfers or providing other monetizable information to cybercriminals.

    They do this by pretending to be the CEO, CFO, or other important people in the organization and can even impersonate your trusted partners or other well-known internet brands. Some also target departments responsible for sensitive employee data, such as payroll, which is used for identity theft. Detecting and blocking these types of attacks requires deep inspection of the content of an email without impacting delivery speed.
