## Overview

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.

## Pricing & Plans

Custom pricing quoted per mailbox, scoped to your deployment size and mail platform. There is no public price list; every engagement starts with a 14-day proof of concept that runs alongside your current stack.

## Key Features & Capabilities

- **TRACE reasoning engine:** 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.
- **Inbox Advisor:** 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.
- **Threat Triage:** Reported phish arrive as pre-investigated cases complete with the evidence and reasoning trace your SOC needs to close them quickly.
- **Threat Hunt:** Turn a single suspicious email into an organisation-wide sweep to find related messages that other filters delivered.
- **Intent Workflows:** 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.

## Primary Use Cases

- **Catch what your gateway misses (Security teams on Microsoft 365 or Google Workspace):** Catch first-seen AI-written phishing and business email compromise that signature and ML filters deliver because nothing matches a known pattern.
- **Stop payment-diversion fraud (Finance and accounts payable):** Verify first-ever bank changes and access requests against organisational policy before accounts payable acts, reducing wire fraud and supplier impersonation.
- **Protect AI assistants from prompt injection (Teams deploying AI assistants):** Detect hidden instructions embedded in email that target assistants such as Copilot, Gemini and Claude.
- **Reduce triage time (SOC and incident response):** Cut the hours spent investigating user-reported phish by delivering pre-investigated cases with evidence attached.

## Strengths

- Reasons about intent rather than relying on signatures or anomaly scores
- Rapid API-based deployment with no MX changes
- Plain-English reasoning trace on every verdict
- 14-day proof of concept before purchase
- Integrations with Microsoft Sentinel, Splunk and Radiant Security

## Limitations

- Pricing is quote-only, so small teams cannot self-serve or see list prices upfront
- Focused on Microsoft 365 and Google Workspace mailboxes, so it is not a fit for other mail platforms
- Agentic reasoning layer adds depth that smaller organisations without a SOC may not fully operationalise
