Fight Fire with Fire by Choosing AI-Enhanced Email Security

March 29, 2024

AI-Enhanced Email Security is Ready for Sophisticated Threats


Email remains a critical channel for business operations, serving as the lifeline for internal and external communications. However, this reliance on email also brings the potential for email-based cyberattacks to every company’s doorstep. With the rise of sophisticated techniques like AI phishing and social engineering, traditional email security measures are no longer sufficient. Businesses need to take email security seriously to prevent cyber trouble by taking proactive actions like adopting powerful, AI-enhanced email security solutions. Unfortunately, too many businesses aren’t investing in the kind of email security that can handle today’s threats. Here’s why email security needs to be a priority.

In our Kaseya Security Survey 2023, we asked respondents about the vectors through which their organization might suffer a successful cyberattack. One-quarter of our respondents chose email, highlighting the importance of having powerful, layered email security solutions in place to minimize risk. Nearly another one-quarter of survey respondents said that they consider endpoints to be their most vulnerable vector (23%). It is interesting to note that 22% of respondents chose a people-related vector, human error or insider threat, as the most likely conduit for a successful cyberattack against their employer. This result reinforces the importance of security awareness training for every employee. Education and training dramatically reduce a company’s risk of falling prey to a cybersecurity incident.  

Which of the following threat vectors are you most concerned about being the gateway to a successful attack in the next 12 months?

Attack Vector  Response  
Email  25%  
Human error (social engineering, distraction)  16%  
Endpoint (server)  12%  
Endpoint (laptop)  11%  
Cloud  10%  
Network  8%  
Insider threats  6%  
Supply chain  5%  
Unpatched systems (Zero-day attacks)  5%  
None  2%

However, according to our respondents, businesses aren’t making investments to improve their email security. Cloud security (28%), cyber insurance (27%) and endpoint detection and response (EDR) (26%) are the top three areas in which respondents said they plan to invest in the next year. Surprisingly, only 17% of respondents are planning to invest in security awareness training, a low-cost way to reduce security incidents by up to 70%, and 3% of respondents said their companies will not be making any cybersecurity investments at all.  

Which of the following cybersecurity investments do you anticipate making in the next 12 months?   

Investment  Response  
Cloud security  28%  
Cyber insurance  27%  
Endpoint detection and response (EDR)  26%  
Dark web monitoring   23%  
Email/collaboration tool security  23%  
Network security  20%  
Managed SOC/MDR  19%  
Automated pen testing  18%  
Security awareness training  17%  
Secure remote access (SASE)  15%  
Vulnerability assessment  13%  
We do not anticipate investing in cybersecurity  3%

Cybercriminals are continually evolving their strategies to breach corporate defenses, using advanced technologies to craft highly convincing phishing emails and social engineering schemes. These attacks are not only becoming more frequent but also more sophisticated, leveraging AI to convincingly mimic legitimate communication patterns, making them increasingly difficult to detect. AI phishing, for example, uses machine learning algorithms to generate highly personalized phishing emails, bypassing traditional detection methods. Social engineering attacks, on the other hand, exploit human psychology, tricking employees into divulging sensitive information or granting access to secure systems. 

While traditional phishing emails often rely on fraudulent links or deceptive language, a new and more sinister trend is emerging: the use of deepfakes. A deepfake is a false piece of media, typically audio or video, in which bad actors manipulate or replace content to serve their purposes by making it appear as though it is authentic and created by the depicted individual. It’s a powerful social engineering tool. The advent of artificial intelligence (AI), especially generative AI, has helped cybercriminals create highly believable, sophisticated deepfakes that can fool even savvy victims.

But AI doesn’t have human weaknesses, so it is immune to social engineering. It’s not going to fall for faked indicators of authenticity or scare tactics, removing human error and cybercriminal trickery from the equation. Every incoming message is compared to the baseline using dozens of points of comparison. AI will spot deviations from a company’s normal communication pattern that people might miss. In response to these evolving threats, AI-enhanced email security emerges as a critical solution. Here’s how AI can fortify a business’s email security posture: 

Advanced Detection Capabilities: AI algorithms can analyze email content, including text and attachments, in real time to identify suspicious patterns, anomalies, and indicators of phishing or malicious intent. This goes beyond traditional keyword or signature-based approaches, offering a more dynamic and adaptive defense mechanism. 

Behavioral Analysis: By learning the normal communication patterns within an organization, AI can detect deviations that may indicate a social engineering attempt. This includes unusual sender behavior, unexpected email content, or irregular sending times. 

Predictive Analytics: AI systems can use historical data to predict and identify potential threats before they reach the user’s inbox. This proactive approach can significantly reduce the risk of successful cyber attacks. 

Automated Response: Once a threat is detected, AI-enhanced systems can automatically quarantine suspicious emails, block malicious senders, or prompt users for additional verification. This immediate response limits the potential damage and reduces the burden on IT security teams.

Investing in AI-enhanced email security is not just about mitigating cyber risks; it’s also a smart, strategic business decision. Here are four key benefits: 

  1. Protecting Sensitive Data: By preventing phishing and social engineering attacks, businesses can safeguard their proprietary information, customer data, and intellectual property. 
  2. Maintaining Business Continuity: Cyber attacks can disrupt operations, leading to significant financial losses. AI-enhanced security helps ensure that business activities can proceed without interruption. 
  3. Building Trust: Customers and partners trust businesses with their data. Demonstrating a commitment to advanced security measures can strengthen these relationships and enhance a company’s reputation. 
  4. Compliance and Legal Protection: Many industries are subject to regulations that require the protection of sensitive information. AI-enhanced email security can help businesses meet these compliance requirements, avoiding legal penalties and fines.
