- Adaptive Security Agentic Email Security and Phish Triage — API-based 'agentic email security' that re-analyses inbound mail after native filtering with ML and LLM reasoning and removes confirmed threats across every inbox automatically (configurable human-in-the-loop thresholds). AI Phish Triage classifies employee-reported emails and acts on them, feeding Adaptive's simulations and awareness training. · Adaptive Security Agentic Email Security and Phish Triage pair comparison
- Contrast AI SmartFix (agentic vulnerability remediation) — An AI agent that runs as a GitHub Action, takes vulnerabilities found by Contrast's IAST (Assess) and SAST, writes code fixes using runtime context, runs your build and tests, and opens pull requests for developers to review.
- Deep Fathom Compliance Readiness Platform (agentic CMMC / NIST SP 800-171 readiness) — CMMC and NIST SP 800-171 readiness platform for US defence contractors where AI agents interpret obligations, plan and advance routine readiness work, continuously map the CMMC boundary and collect evidence, with human review gates on consequential decisions.
- 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
- ManageEngine Endpoint Central Zia Agents (EDR Event Triage, Device Investigation and Patch Troubleshooting agents) — Prebuilt AI agents in ManageEngine Endpoint Central that triage EDR events (MITRE ATT&CK mapping, prioritized next steps), investigate device problems and diagnose failed patches, plus Agent Studio for custom endpoint agents. · ManageEngine Endpoint Central Zia Agents (EDR Event Triage, Device Investigation and Patch Troubleshooting agents) 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
- Veeam PrivacyOps AI agents (Consent Agent, DSR and Assessment agents) — Privacy-operations agents on Veeam's DataAI Command Platform: a generally available Consent Agent that builds, tests, monitors and auto-remediates consent across sites and downstream systems, plus announced DSR intake-form and assessment-autofill agents.
