Email Security

Why Email Security is Important and How to Ensure it?

Email is a vital communication tool for small businesses, but it also exposes them to various cyberattacks that can harm their data, money, and reputation. Therefore, email security is essential to protect your business from these threats, and to improve your stability, productivity, and customer trust. In this article, we will show you why email security is important for small businesses, how you can achieve it, and how it will benefit the businesses.

Why Email Security is Important for Small Businesses

Email is a crucial tool for businesses, but it also exposes them to serious security risks. Cybercriminals can exploit email to launch attacks and steal valuable information, resulting in financial losses, reputational damage, and other detrimental consequences.  Therefore, small and large businesses need to prioritize and implement robust email security measures to safeguard their data and ensure smooth business operations. In this section, we will explain the main reasons why email security is important for small businesses.

Email is the Number One Attack Vector

According to a report, more than 90% of cyberattacks start with malicious emails. This means that if your business uses email, it is at risk. Email is a popular way for cybercriminals to initiate attacks because it is widely used and employees receive a large number of emails.  This overwhelming volume can lead employees to become less cautious and more prone to falling for phishing attacks, especially with the rise of cloud-based email services.

Email Attacks Can Cause Severe Damage

Email attacks can cause severe damage to your business, both in terms of financial and non-financial losses. To illustrate, a phishing email can be crafted to deceive an employee into revealing their login credentials. These stolen credentials can then be exploited to gain unauthorized access to both on-site and cloud-based services, leading to data breaches or other malicious activities.

Additionally, a business email compromise (BEC) scam can trick victims into believing they are engaging in a genuine business transaction, leading to the transfer of money or sensitive information to the cybercriminals involved. A spear-phishing or whaling attack can target high-profile or rich individuals, such as CEOs, top-level executives, or famous people, to obtain private information or money from them.  According to a report by Heimdal Security, the average cost of a successful email attack is $1.6 million for small and medium-sized businesses.

Email Security Can Improve Your Business Performance

By having email security, you can benefit from improved business stability, productivity, and performance. You can prevent server downtime due to viruses or other issues, reducing time and money wasted for the business.  You can also protect your sensitive data and intellectual property from unauthorized access or leakage, ensuring compliance with regulations and standards. Additionally, you have the opportunity to strengthen customer trust and loyalty, as well as establish a competitive advantage in the market. Email security is not a luxury, but a necessity for your business.

AI-Based Email Security for Small Businesses

Artificial Intelligence (AI) is a field within computer science that empowers machines to carry out tasks that typically rely on human intelligence, such as learning, reasoning, and making decisions. AI can be utilized in multiple facets of email security, including the identification, prevention, and response to potential threats. We will explain how AI can help small businesses protect themselves from email threats, and what are the benefits and challenges of using AI-based email security solutions.


AI can help small businesses detect email threats faster and more accurately compared to traditional methods. It can examine the content and context of emails to quickly figure out if they are spam, part of phishing attempts, or genuine.  AI can also use machine learning and computer vision to analyze the text, context, and images in emails and web pages to block malicious activities.

For example, AI can identify behavioral, textual, and organisational anomalies to block phishing, spear phishing and business email compromise.  AI can also predict email, URL, webpage, and file behavior to block malware emails, webpages, attachments, and hosted files.


AI can help small businesses prevent email threats from reaching their inboxes or compromising their systems. AI can use natural language processing and natural language generation to create and send personalized and convincing responses to phishing emails, diverting the attackers’ attention and wasting their time. Additionally, AI has the capability to employ encryption and digital signatures to safeguard email communication, guaranteeing the legitimacy and integrity of both the sender and the recipient.


AI can help small businesses respond to email threats effectively and efficiently. AI can use automated incident response and remediation to isolate, contain, and remove email threats from the affected systems.  AI can also use data analysis and visualization to provide insights and recommendations to the security teams and the users on how to improve their email security posture and behavior.

Benefits of AI-Based Email Security

AI-based email security solutions can offer several benefits to small businesses, such as:

  • Improved accuracy and speed: AI can reduce the false positives and false negatives that often plague traditional email security solutions. AI can also process large volumes of emails and data faster than human analysts, reducing the time to detect and respond to email threats.
  • Reduced costs and complexity: AI can automate and streamline many email security tasks that would otherwise require human intervention and expertise. AI can also integrate with existing email security solutions and platforms, such as Microsoft 365, reducing the need for additional hardware or software.
  • Enhanced user experience and trust: AI can provide user-friendly and intuitive email security features, such as intelligent email protection, that can help users avoid email threats and improve their email hygiene. Furthermore, AI can enhance customer trust and loyalty by providing assurance that their email communication is secure and confidential.

Bottom Line

To sum up, email security is vital for small businesses as it helps protect against cyberattacks that can jeopardize data, finances, and reputation. By implementing effective measures and utilizing AI-based solutions, businesses can enhance their stability, productivity, and customer trust, ultimately leading to improved overall performance.
