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.

Sendmarc Releases DMARCbis Fireside Chat Featuring Co-Editor Todd Herr

In a recent DMARCbis fireside chat, email authentication leaders discussed upcoming DMARC changes and how teams can plan for 2026. Sendmarc has released a new fireside chat featuring Todd Herr, Principal Solutions Architect at GreenArrow Email and co-editor of DMARCbis, on the upcoming update to DMARC (Domain-based Message Authentication, Reporting, and Conformance).

What Happens If I Click A Phishing Link?

Phishing is the most prominent form of cyber-attack, regularly prompting email recipients into disclosing their personal information, credentials, downloading malware, or paying fraudulent invoices. Phishing can result in cybercriminals gaining unauthorized access to organizations’ data, network systems, or applications. People can be understandably alarmed once they realize they’ve clicked on a phishing link.

Phishing Kit Attacks Are Now Everywhere: How SOC Analysts Can Detect Them

Phishing kits have changed the speed of compromise. Attackers no longer need malware or complex tooling. With ready-made phishing platforms, they can launch large-scale credential theft campaigns that bypass MFA and deliver valid sessions almost instantly. By the time an alert reaches the SOC, the attacker may already be inside. Stopping these attacks now depends on seeing the full phishing chain early, before stolen access turns into business damage.
