Resources Hub - What Is an Email Filtering Service & How Does It Work to Secure Email?

Spam emails and phishing email attacks carrying malware and ransomware have increased the necessity for vital, robust, dependable email filtering services. As these email threats evolve, companies need more efficient ways to stop spam emails and other types of email attacks.

Fortunately, Machine Learning (ML) devices have more knowledge to detect and quarantine emails that could be deemed suspicious and harmful to your server. Such adjustments can be beneficial when employees have other tasks they must focus on rather than the security of their online exchanges. This article will discuss the basics of email filtering, how these services find email threats, and what opportunity we offer to help you mitigate these email security risks.

What is Email Filtering and How Does It Secure Email?

Email filtering services scan through an organization’s email traffic and classify these messages into various categories, including spam, malware, viruses, and suspicious links.

Use an inbound email filtering service. To find fraudulent or malicious emails, you can use email security technologies and techniques like malicious URL filtering, dynamic file analysis, and heuristics. The filters will quarantine emails like these so end users only see the safe, legitimate messages in their inboxes. Outbound email filtering checks messages before they can reach the recipient and harm their party. Organizations deploy this cloud email security solution frequently to help fulfill their business requirements for online safety.

These security measures can serve your company by guaranteeing that users rarely interact with spam messages that could severely impact the company’s reputation, data, and overall capabilities.

Consider what your company needs to take care of so that you can choose an email filtering service that best suits your requirements. Email security solutions focusing on online and cloud email security are crucial for businesses that need flexibility and scalability in their enhanced security defenses. These services offer ongoing system management and support to keep email threats out of your inbox.

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.
