IRONSCALES is an AI-powered email security platform designed to detect and stop phishing, spoofing, and business email compromise attacks. Thus, it works as a second layer of protection on top of Microsoft 365 or Google Workspace, using machine learning and crowd-sourced intelligence to identify threats traditional spam filters miss. Besides, it allows users to report suspicious emails and provides automated remediation across the organisation.

What exactly is IRONSCALES email security?

IRONSCALES is a cloud-based layer 2 email security solution. That means it doesn’t replace your Microsoft or Google spam filter — it enhances it to make sure your business is protected from phishing attacks. So, it has other features traditional spam filters don’t.

It specialises in detecting modern phishing techniques such as:

  • Impersonation emails
  • Brand forgery
  • Supplier fraud
  • Payment diversion attempts
  • Business email compromise (BEC)
  • Zero-day phishing attacks

Traditional filters scan for malicious links or attachments, but IRONSCALESscans for intent and behaviour — the things most attacks rely on today.

How does IRONSCALES potect businesses from phishing?

1. AI-assisted threat detection

IRONSCALES analyses each email using behavioural signals, sender reputation, writing style patterns, and known phishing fingerprints.

2. Real-time threat intelligence

If a phishing email is detected anywhere globally, the entire IRONSCALES community is protected within minutes.

3. Phishing simulation & training

Users receive realistic phishing tests and tailored micro-learning.

4. Automated remediation

If IRONSCALES finds something malicious on one mailbox, it removes it from all inboxes automatically.

5. User-friendly reporting tools

One-click reporting lets employees flag suspicious emails without calling IT.

What real-world phishing examples have IRONSCALES stopped?

From client environments, IRONSCALES has caught:

  • Fake “Microsoft password reset” emails
  • Supplier impersonation with real invoice attachments
  • “CEO urgent request” fraud
  • Banking credential harvesters
  • Fake DocuSign, Sage, and QuickBooks emails

These often pass default Microsoft filters and that is why having layered email security is so important. So, if a suspicious email passes the first layer, the second layer can stop it. To understand more about layered email security, you can check out this article that explains it in detail.
