AI email security that stops attacks before they reach your people.

You stop checking. We don't.

Our agents do the homework an attacker would do on you, build the phishing attacks aimed at your people, and harden your defenses before the first one lands. Your team weighs in on what needs a call, we handle the rest.

The phishing renaissance

Every phishing email is now built for the person reading it.

Phishing is having a renaissance. The old attacks are back, rebuilt and sent by AI, personal by default, and now aimed at agents as well as people. Every email security tool on the market waits for the attack, then reacts. None get ahead of it. We call this Phishing 3.0.

98.4% of security leaders say attackers are already using AI against them. Osterman Research, Using AI to Enhance Defensive Cybersecurity, 2025
16% faster Teams remediate each phishing email 16% faster than in 2022 and spend 9% more of their year on phishing anyway. Osterman Research, The (Higher) Business Cost of Phishing, 2026
$51,948 per security analyst, per year, spent on phishing. Up 13.6% in three years. Osterman Research, The (Higher) Business Cost of Phishing, 2026

Security teams got more efficient at fighting phishing. Attackers got more efficient at creating it.

Our point of view

Detect, investigate, respond was built for attacks that arrive one at a time. This wave arrives all at once, and it has already been rehearsed against your people. So we stopped waiting for it. Our agents research your organization the way attackers do, build the attacks aimed at you, and harden your defenses before the first message lands.

Nothing is trusted until we've tried to break it.

Preemptive by design

Three AI agents in one preemptive system.

Ours anticipates. Three agents research, test, and train against your organization, so the attack built for your people is already a detection by the time it arrives.

Red Teaming Agent Anticipates. Powered by Claude

Your Red Teaming Agent anticipates. Continuous reconnaissance, attacks designed for your organization, detection hardened before they arrive.

Every attack becomes a detection. Built by the agent, pushed into your detection stack before an attacker sends it. New reconnaissance every 7 days.
Phishing SOC Agent Investigates.

Your Phishing SOC Agent investigates. L2-level forensics on every suspicious email in minutes, with the evidence to act. Not hours. Not "we'll get to it."

97 seconds average L2 investigation, evidence attached. No queue, no ticket, no waiting for an analyst.
Phishing Simulation Agent Educates. Powered by Claude

Your Phishing Simulation Agent educates. Real reconnaissance, real attacker tactics, and training aimed at the people those attacks would target.

Every simulation has a source. The post, the event, or the press release that made it believable, aimed at the people it would fool.

One anticipates. One investigates. One educates.

The part you can't get anywhere else.

Most AI email security learns from one place: your own mailboxes. Ironscales learns from 36,000 security professionals across 18,000 organizations feeding real verdicts into the same AI. The moment one team gets hit, yours is already protected.

And none of it is a black box. Your admins see what the AI decided and why, on every verdict, and they decide how much runs on its own.

If the AI can't explain a verdict, it doesn't get to make one. You set the automation thresholds, from full autopilot to human in the loop.
Protect

We catch the attacks others miss.

Urgency-based emails. Vendor impersonation. The tells a gateway was never built to see. Adaptive AI catches them, learning from every mailbox it protects and from the security professionals who report what slipped past everyone else.

Case Studies

It’s about as close to ‘set it and forget it’ as you can get, especially compared to the daily management a traditional gateway requires with all its rules and policies.

Answers for the people who run email security

What is Ironscales?

Ironscales is an AI email security platform that stops phishing, business email compromise, account takeover, and deepfakes across Microsoft 365 and Google Workspace. It runs three AI agents that anticipate, investigate, and educate, backed by a community network of 36,000+ security professionals across 18,000+ organizations. Ironscales was the first email security vendor verified under Anthropic's Cyber Verification Program.

How is Ironscales different from a secure email gateway (SEG)?

A secure email gateway inspects mail at the perimeter and waits for a known-bad signal. Ironscales works inside the mailbox through a native API, learns how each organization actually communicates, and remediates threats after delivery, including the targeted attacks a gateway passes. Deployment takes minutes with no MX record changes.

Does Ironscales replace Microsoft 365 or Google Workspace email security?

Ironscales augments Microsoft 365 and Google Workspace instead of replacing them. Native email security handles commodity spam and known threats. Ironscales adds behavioral AI, account takeover protection, deepfake detection, and human risk management for the targeted attacks that still reach the inbox.

What do the Ironscales AI agents do?

Ironscales runs three agents in one platform. The Red Teaming Agent researches your organization the way an attacker would and builds the attacks aimed at your people. The Phishing SOC Agent runs the level-two investigation when an employee reports an email and attaches the evidence. The Phishing Simulation Agent turns that same reconnaissance into training for the people a real attack would fool. One anticipates, one investigates, one educates.

Is the AI a black box?

No. Ironscales Adaptive AI shows its work, so every verdict carries the evidence behind it and your team stays in control of what needs a human call. Ironscales was the first email security vendor verified under Anthropic's Cyber Verification Program, and Anthropic's safety controls apply to everything Ironscales does in that program.

Does Ironscales work for MSPs and multi-tenant management?

Yes. Ironscales gives managed service providers multi-tenant administration, per-tenant policies, and consolidated reporting across every client from one console, with human risk management and phishing simulation included.

Nothing is trusted until we've tried to break it.
