Agentic AI email security that reasons about intent

Caught a zero-day spear phishing attempt that bypassed both Microsoft Defender and Proofpoint on day one.
The plain-English explanations for every security verdict make incident triage infinitely faster for our SOC.
Onboarding takes some careful policy tuning across shared mailboxes.
Absolute game changer.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
A multi-LLM ensemble reads intent, checks each message against your business context and relationships, and returns a clear verdict instead of relying on signatures or anomaly scores.
Get a plain-English verdict on every message, so anyone on the team can understand why an email was allowed or blocked without reading raw headers.
Reported phish arrive as pre-investigated cases complete with the evidence and reasoning trace your SOC needs to close them quickly.
Turn a single suspicious email into an organisation-wide sweep to find related messages that other filters delivered.
Verify payment and access requests against your policies before anyone acts, and detect hidden instructions aimed at AI assistants such as Copilot, Gemini and Claude.
StrongestLayer was founded by operators who helped build the previous generation of email security at Proofpoint, McAfee, Google, Mandiant and FireEye. Their central argument is that AI now writes attacks from scratch, so rules miss them because they are new and machine learning misses them because they look routine. In response, the platform asks a different question: what is this email trying to accomplish?
The product is built around TRACE, a multi-LLM reasoning engine that organises its agents into three classes: Advisor, which returns a verdict on every email; Triage, which delivers pre-investigated cases; and Hunt, which sweeps the organisation from one sample. Intent Workflows extend the same reasoning to payment and access requests, and to hidden prompt-injection instructions aimed at AI assistants like Copilot, Gemini and Claude.
Deployment is deliberately low-friction. StrongestLayer connects through the Microsoft Graph or Google Workspace API in roughly fifteen minutes with no MX changes, so it runs alongside Proofpoint, Mimecast or native filtering. Every plan starts with a 14-day proof of concept that measures threats reaching inboxes and analyst time saved before you commit.
Catch first-seen AI-written phishing and business email compromise that signature and ML filters deliver because nothing matches a known pattern.
Verify first-ever bank changes and access requests against organisational policy before accounts payable acts, reducing wire fraud and supplier impersonation.
Detect hidden instructions embedded in email that target assistants such as Copilot, Gemini and Claude.
Cut the hours spent investigating user-reported phish by delivering pre-investigated cases with evidence attached.
