StrongestLayer
Email security that reads intent and business context with several models, aimed at the phishing that gets past conventional filters.
Highlights
- A TRACE engine running a multi-LLM ensemble to reason about email intent and infrastructure
- Inbox Advisor: an inline safe, caution, or block verdict embedded in Outlook and Gmail
- Threat Triage: pre-investigated, explainable verdicts for security teams
- Threat Hunt: org-wide retroactive sweeps by sender, subject, URL, or domain
- API-based deployment for Microsoft 365 and Google Workspace with no MX changes
- A focus on advanced phishing, business email compromise, and adversary-in-the-middle attacks
- In-memory content processing with metadata-only retention
- An AWS Marketplace listing and a 14-day proof of concept

About StrongestLayer
What it is
StrongestLayer analyses email using multiple language models to judge intent and business context rather than matching signatures or reputation, targeting phishing, business email compromise and adversary-in-the-middle attacks that conventional gateways pass through.
Why it's different
The reasoning is sound and the threat has genuinely changed. Traditional filters catch mass campaigns with detectable artefacts — bad grammar, known-bad links, spoofed headers. A modern business email compromise has none of those: it is a well-written message from a real compromised account asking for something plausible, and the only signal is that the request does not fit the business context. Judging that is the right thing to automate. The caveats are the ones every detection layer has: false positives on legitimate unusual requests train people to release from quarantine without reading, and no filter removes the need for a call-back rule on payment changes.
How people use it
It is deployed alongside an existing gateway rather than instead of it, catching what gets through. The measurable outcomes are business email compromise attempts caught and, just as importantly, the false-positive rate — a tool that quarantines real invoices creates a habit that defeats it. Pair it with a process rule for anything moving money, because process beats detection on the attacks that matter most.
