AI for email security has become a necessity with the increasing sophistication of such as phishing, malware and data breaches. It is getting harder for people and businesses to identify and protect themselves from these threats. Awareness of these email threats and email security solutions can greatly affect your ability to protect yourself.

This article spreads awareness about the use of AI in email security and explains why you should choose AI email security over traditional email detection tools and security solutions to defend yourself against phishing attacks and fraud.

Why do we need AI for email security?

The complexity of email breaches is increasing by the day. Hackers are leveraging machine learning and AI tools to create better-crafted phishing emails or business email compromise (BEC) scams, making them very difficult to distinguish from safe emails. This makes it very difficult for cyber security teams to detect and fight such attacks using traditional means. While humans control the entire process of the safekeeping of confidential information, AI tools empower them to do it better and faster.

How AI email security defends you from fraud

Let's take a look at how helpful AI is for email security and how it aids in today’s email security endeavors.

An infographic showing a list of ways how AI email security defends you from fraud along with a tool for each use case

1. Anomaly detection and behavioral analysis

AI tools can leverage the power of machine learning to learn the normal patterns of communication within an organization and form a baseline of behavior. It can then analyze metadata, email content and sender behavior to detect anomalies that deviate from pre-defined behavioral baseline to identify potential threats.

2. Email content analysis

AI utilizes natural language processing (NLP) techniques to understand the context of the emails received. AI's sentiment analysis capabilities also help it understand these emails more deeply. This enables it to identify emails with malicious intent, harmful content and hacking attempts.

SlashNext is a security solution that uses NLP to detect and prevent credential stealing, BEC, spear-phishing, legitimate link compromise, social engineering scams, ransomware and malware in real time.

3. Filtering spam emails

AI algorithms allow for advanced filtering of emails. The spam filtering system continuously improves by learning from vast data sets daily. These filters can use sentiment analysis and NLP to understand emails better and segregate them from the more important ones. It reduces the chances of spam ending up in your inbox, thereby reducing the chances of attacks through phishing emails and other email threats.

Vade, for instance, is an anti-spam solution that uses AI, machine learning and Deep Learning to provide advanced spam detection features.

4. Detection of malicious attachments and URLs

AI can scan and analyze attachments and URLs in emails in real time. It can examine file types, behavior and reputation of the attachments and the link to detect malicious attachments or suspicious links that may lead to risky websites.

Trustifi’s Inbound Shield provides this service to you where it performs a deep analysis of links based on content, metadata and domain reputation and even scans links within files, zip and achieve files, trojans, viruses and malware. Look at the image below to understand how their multilayered protection works.

5. Threat analysis

AI can collect and analyze vast amounts of data from threat intelligence feeds and identify emerging threats. It can continuously monitor network traffic, trends, patterns and other indicators of compromise, which enables better detection. This makes for better threat intelligence over time which keeps getting better. AI can continuously learn and adapt based on new threats and techniques. So it grows with the cybercriminals to stay ahead of emerging threats.

Darktrace is one such solution that helps organizations protect themselves from attacks by better analyzing historical data and stopping future attacks.

6. Incident response and quarantine procedures

AI automates incident response and quarantine procedures when a potential threat is identified. It can monitor emails in real time and take actions based on predefined workflows. This can streamline the incident response processes and mitigate risks more efficiently. Ironscales, for instance, provides you with AI-powered incident response.

7. Deception Technologies and Intelligent Traps

AI email security systems will incorporate deception technologies and intelligent traps in the future. They will be integrated closely with the email security systems as virtual decoys to learn and understand the hackers' tactics and techniques. These decoys will then be able to provide valuable insights into the emerging threats to help organizations stay ahead of the hackers.

Cynet, for instance, is a company that offers deceptive technology in its security solutions. AI can help speed up the setting up of such technologies.

8. Threat intelligence sharing

Collaboration and sharing of information will become important in AI email security. Organizations will leverage AI to gather and analyze information on various online threats from different sources like industry pages and security vendors. This will enhance the capability of AI email security systems to defend themselves against hackers.

Miemcast is a security provider that talks much about threat intelligence sharing and how it can help organizations prepare for attacks before they even begin.
