- Check Point Email Security AI agents (Harmony Email & Collaboration, formerly Avanan) — Check Point's API-based, prevention-first email and collaboration security (Harmony Email & Collaboration, formerly Avanan) for Microsoft 365, Gmail, Teams, Slack and file-sharing apps. Check Point says autonomous AI agents investigate threats, correlate activity into campaigns, prioritise incidents and orchestrate remediation. Check Point Infinity Platform for Government (which includes Harmony Email) is FedRAMP Moderate and GovRAMP Authorized at platform level; Check Point Harmony is TX-RAMP Level 2 — none of those registry rows name the AI agents. · Check Point Email Security AI agents (Harmony Email & Collaboration, formerly Avanan) pair comparison
- Hoxhunt Respond (automated phishing incident response) — Finnish human-risk platform whose Respond module automatically investigates every employee-reported email, groups related reports into one campaign incident, suppresses safe and duplicate reports, and removes confirmed malicious messages from all affected inboxes without waiting for an analyst. · Hoxhunt Respond (automated phishing incident response) pair comparison
- Ironscales AI agents (Phishing SOC Agent, Red Teaming Agent and Phishing Simulation Agent) — API-based email security for Microsoft 365 and Google Workspace that runs three AI agents: a Phishing SOC Agent for L2-style forensic investigation of suspicious emails, a Red Teaming Agent that models attacks aimed at your organisation and hardens detection, and a Phishing Simulation Agent. Plans include agentic autonomous remediation. · Ironscales AI agents (Phishing SOC Agent, Red Teaming Agent and Phishing Simulation Agent) pair comparison
- Material Security AI agents (user-reported phishing agent and OAuth Remediation Agent) — Cloud workspace security for Google Workspace and Microsoft 365 with an AI agent that triages, clusters and remediates user-reported phishing across the organisation, plus an OAuth Remediation Agent that investigates third-party app and AI-agent grants and can revoke tokens on its own. Per-user pricing is published. · Material Security AI agents (user-reported phishing agent and OAuth Remediation Agent) pair comparison
- Phished AI security agents (Report Triage, Orchestration, Simulation and Real-Time Protection agents) — Belgian human-risk platform with a suite of AI agents that run the phishing training programme (orchestration, simulation, brand, supplier and deepfake simulation agents), triage every reported email with a verdict and a drafted reply, and check clicked links in an isolated environment in real time. New content needs admin approval and every action is logged. · Phished AI security agents (Report Triage, Orchestration, Simulation and Real-Time Protection agents) pair comparison
- Proofpoint Satori agents (Abuse Mailbox Agent and DLP Triage Agent) — Agentic AI layer inside Proofpoint's platform. The Satori Abuse Mailbox Agent classifies every user-reported email that needs manual review (phish, malware, spam or clean) and can trigger configured quarantine or tagging workflows. A DLP Triage Agent does the same for data-loss alerts, with guardrails, chat explanations and audit logs. · Proofpoint Satori agents (Abuse Mailbox Agent and DLP Triage Agent) pair comparison

- StrongestLayer TRACE agents (Inbox Advisor, Threat Triage and Threat Hunt) — AI-native email security for Microsoft 365 and Google Workspace in which a multi-LLM reasoning engine (TRACE) investigates each email's intent against your business context and blocks attacks. Three classes of agents give employees plain-English verdicts in Outlook and Gmail, send pre-investigated, MITRE-mapped cases to the SOC, and hunt and remediate across mailboxes. · StrongestLayer TRACE agents (Inbox Advisor, Threat Triage and Threat Hunt) pair comparison
- Sublime Security ASA and ADÉ (Autonomous Security Analyst and Autonomous Detection Engineer) — Email security platform whose AI agents triage user-reported and flagged emails end to end (ASA, with passive or active auto-remediation modes) and write backtested detections for new attacks (ADÉ), which default to one-click human approval and can auto-activate when they clear a precision threshold. Runs as SaaS or self-hosted in AWS, including GovCloud. · Sublime Security ASA and ADÉ (Autonomous Security Analyst and Autonomous Detection Engineer) pair comparison
