What Threats Does an Email Filtering Service Protect Against?

Email filtering services are excellent at keeping dangerous and disruptive email threats away from your business. These spam filters can block any of the following types of email attacks:

  • Spam Emails: These unsolicited junk emails sent in bulk are notorious for the aggravation, distraction, and disruption they cause. If opened, these serious email security threats can contain malicious phishing email attacks and dangerous ransomware. Email security issues can lead to Business Email Compromise, significant downtime, reputational harm, and overall data loss.
  • Email Viruses: These email messages with malicious code account for most computer viruses because users can activate them easily. Simply clicking on an email link, downloading an attachment, or interacting with the email in another way can result in an infected, compromised email address. This attack can steal sensitive information, destroy data, harm hardware, and force companies to unsuccessfully use time, resources, and energy to stop the email threat.
  • Phishing Attacks: Threat actors send a malicious email that convinces a user to reveal financial information, sensitive data, and login credentials, unknowingly permitting hackers the ability to break into a system. Due to its believability and effectiveness, these leading email security threats account for over ninety percent of email attacks.
  • Malware: This software disrupts and damages the safety of a system by gaining unauthorized access to a computer system to perform various harmful operations. This type of threat can encrypt and delete sensitive data, steal and alter central computing functions, and monitor user activity without their knowledge or permission. Ransomware, a more specialized type of malware, takes over a system and only promises to return controls to authorized users once they pay a large amount of money to the hacker.
  • Zero-Day Attacks: These email threats occur when a cybercriminal exploits specific vulnerabilities in a system that developers have not patched. Zero-day attacks can be quite dangerous since the attacker can act immediately or at the right time in the future. These threat types can go unnoticed for an extended period but can be just as detrimental for businesses, if not more so.
  • CEO Fraud: Also known as Business Email Compromise or whaling, this email scan targets a group in business by impersonating a C-level executive, such as a CEO, through compromised email addresses and false contact information to trick recipient employees into providing them access to financial information and sensitive data. This malicious type of phishing attack tricks users into acting quickly to share valuable data with higher-ups without ever knowing their actual identity.
