What is email threat prevention? A complete guide in 2026

Email Security Email Security Stop modern email-borne attacks with real-time AI defense. Please wait, this may take a few seconds... Email threat prevention is a comprehensive security technique that identifies, blocks and neutralizes email threats such as phishing, malware, and business email compromise (BEC) before they reach a user’s inbox. It combines multiple layers of defense, including AI-driven analysis, URL scanning, attachment sandboxing and authentication protocols like DMARC.

Threat Actors Abuse Messaging Platforms to Launch Phishing Attacks

Messaging platforms are now a major vector for phishing and other social engineering attacks, according to a new report from NCC Group’s Fox-IT. The researchers warn that legitimate messaging apps such as WhatsApp, Telegram, Discord, Signal, LinkedIn, and Gmail-integrated messaging serve as avenues through which attackers can target users while evading email security filters.

Email Security: What It Is, How It Works, and Best Protection Methods

Email-based threats are evolving faster than traditional solutions can keep up. According to Verizon’s 2025 Data Breach Investigations Report, the use of synthetically generated text in malicious emails has doubled over the past two years. That makes it far more difficult to spot social engineering attacks like phishing, which trick users with deceptive messages.

Phishing Simulation: How It Works to Reduce Risk

Phishing isn’t just increasing. It’s outpacing the way many organizations test for it. Attacks have surged 400% year over year, and corporate users are now more likely to be targeted by phishing than by malware. As social engineering becomes a primary entry point into enterprise environments, how you assess phishing risk matters just as much as how often you train for it.

How to Identify a Phishing Website

Our increasing dependence on the internet and, specifically, email for business and personal communication has produced the perfect environment for cybercriminals to launch phishing attacks. As organization’s technical controls have advanced, cybercriminals have evolved their attacks, making them more difficult for traditional email security solutions that use signature-based detection (such as Microsoft and secure email gateways (SEGs) to detect.

How Risky is Sending a Sensitive Work Email to the Wrong Person?

Sending a work email to the wrong person – it’s something all of us have done at least once in our working lives. For some people, it’s a regular occurrence. But just how risky is it? Thinking back over your recent emails, you can probably pick out the ones that would have been worse to misdirect than others. In the best case it’s a non-issue or only slightly embarrassing.

The Case for Behavioral AI in Legal Email Security

For legal organizations, the integrity of communication isn't just a business requirement, it’s a foundational pillar of the profession. Whether it’s a sensitive case strategy, a confidential merger agreement, or personal client data, the information contained within firm emails represents an immense amount of trust and significant liability. However, as law firms increasingly migrate to cloud environments like Microsoft 365, they face a double-edged sword.

The Rise of Kratos: How the New Phishing-as-a-Service Kit Industrializes Cybercrime

By the end of 2026, over 90% of all credential compromise attacks are estimated to be enabled by modular Phishing-as-a-Service (PhaaS) kits like the sophisticated, global threat, Kratos. This aggressive platform has already begun reshaping the threat landscape. At its core, Phishing-as-a-Service (PhaaS) is a malicious cloud-based service that allows easier deployment of phishing attacks and faster updating of features as compared to traditional phishing and malware attacks.

Ep. 47 - APT42 & Iran's AI Social Engineering: Deepfakes, Phishing & Hack-and-Leak

Iran’s APT42 — also known as Charming Kitten or Mint Sandstorm — is redefining social engineering with generative AI, deepfake voice cloning, and long-term phishing campaigns. In this episode of the Cyber Resilience Brief, we break down how Iranian state-sponsored threat actors are using AI-powered phishing, MFA fatigue attacks, credential harvesting, and hack-and-leak operations to target journalists, political campaigns, academics, and enterprise executives.
