What Phishing Simulation Agent does[6][10]
Phishing Simulation Agent gathers OSINT on people, including social media profiles, data breach exposure, and recent job changes, and builds simulations that mirror the tactics targeting the organization. Personalized phishing emails are written in each employee's native language, and one sample per employee cluster is approved by the customer.
What Human Risk Management does[11]
The platform incorporates Human Risk Management: phishing simulation, security awareness training, and user risk scoring modules that automatically tailor simulations to each employee's specific threat profile. IRONSCALES offers a GPT-powered spear phishing module for VIPs and frequently targeted employees.

About IRONSCALES

IRONSCALES sells email security that protects Microsoft 365 and Google Workspace against business email compromise, account takeover, malware and malicious URLs, credential harvesting, generative AI attacks, QR code and image-based phishing, and deepfake impersonation in Microsoft Teams meetings. IRONSCALES connects to Microsoft 365 or Google Workspace through a native API integration, with no MX record changes, no agents, and no mail flow disruption. IRONSCALES can be added behind an existing secure email gateway, and the gateway can be retired later.[7]

Adaptive AI builds a behavioral baseline and social graph using NLP and NLU, learning how users normally communicate. Adaptive AI provides real-time reputation, content, and behavioral analysis to detect malicious threats. Adaptive AI works at the mailbox level and sees internal and external traffic. IRONSCALES combines Adaptive AI with human insight from 36,000+ threat hunters across 18,000+ organizations, so an attack confirmed in one organization is blocked for the rest.[2][7]

Themis is described as an agentic AI virtual SOC that automatically classifies, clusters, and remediates threats detected by machine learning models or user-reported emails. When a threat is detected, Themis takes autonomous action: quarantining, clustering, or escalating based on automation preferences. IRONSCALES automates threat classification, incident clustering, quarantine actions, user notifications, and enrichment with threat intelligence. Admins can configure workflows from alert-only to fully automated remediation and end-user notification. When a user clicks the Report Phishing button, IRONSCALES scans the message, clusters it with similar emails, and evaluates it using Adaptive AI and community insights. The platform integrates with SIEM, SOAR, XDR, and EDR systems to support incident response workflows.[2][9]

Red Teaming Agent runs the same OSINT reconnaissance attackers run, pulling from social media, press releases, job postings, and vendor relationships. Red Teaming Agent generates attack simulations from what it finds. Phishing SOC Agent delivers L2-level forensics in minutes and runs five analysis tracks in parallel: sender verification, body analysis for social engineering, link inspection through the full redirect chain, attachment detonation across 100+ engines, and relay path tracing. Phishing Simulation Agent gathers OSINT on people, including social media profiles, data breach exposure, and recent job changes, and builds simulations that mirror the tactics targeting the organization.[6][10]

The platform incorporates Human Risk Management: phishing simulation, security awareness training, and user risk scoring modules that automatically tailor simulations to each employee's specific threat profile. IRONSCALES offers a GPT-powered spear phishing module for VIPs and frequently targeted employees. IRONSCALES experts handle email threat investigation, remediation, and AI tuning on the customer's behalf.[2][11][12]

Deepfake Protection analyzes voice independently of video, so it catches impersonation even when cameras are off. Protected identity profiles build automatically from normal meeting activity, with no manual uploads and no IT involvement. Outbound email encryption is elective or policy-based, with AES-256 encryption in transit and at rest. Hosted DMARC, SPF, and DKIM come with automated policy enforcement, SPF record flattening, and continuous monitoring with detailed authentication reports. Account takeover protection detects unauthorized access attempts to Microsoft user accounts to prevent data breaches, internal BEC attacks, and ransomware.[10][12]

IRONSCALES was founded in 2014 by alumni of the Israel Defense Forces' Intelligence Technology unit. IRONSCALES is headquartered in Atlanta, Georgia, and Tel Aviv, Israel. Series B funding of $8 million was led by Jump Capital, bringing total financing to $16 million since 2015.
