What took our team 15 minutes to investigate now takes seconds. StrongestLayer fundamentally changed how we handle email threats across our firm.
Phishing attacks aren't just evolving — they're mutating. With generative AI, attackers can craft highly convincing, targeted messages at scale, making traditional defenses obsolete. The real risk isn't just in the inbox — it's in every human decision that follows.
Email security today is mostly a giant pile of rules and signatures. Very brittle, very reactive. And even when vendors say "AI," it's usually just another score glued on top. StrongestLayer approached it cleanly — LLMs first, architecture built around them. It solves problems the legacy stack literally can't.
They aren't tweaking legacy systems, they're rethinking the problem entirely. By analyzing the intent behind messages, StrongestLayer's platform performs more like a team of 1,000 expert analysts, catching threats even when there's no known pattern.
DMARC protects outbound domain reputation against exact spoofing — but covers only ~1% of email threats. It fails to stop lookalike domains, BEC, compromised accounts, and social engineering attacks.

Connects with your SIEM — no new console required.
StrongestLayer is an AI-native email security platform powered by TRACE — the Threat Reasoning AI Correlation Engine. Instead of matching signatures or static rules, TRACE uses a multi-LLM ensemble to reason about every email's sender, intent, and infrastructure the way a human analyst would, and explains every verdict.
Legacy email security relies on signatures, sender reputation, and pattern matching — approaches built before generative AI made every phishing email unique. StrongestLayer is built on LLMs from day one, reasoning about intent rather than recognizing patterns. False positive rates run under 1%, and deployment is 15 minutes via API instead of multi-month migrations.
Fifteen minutes via API. No MX record changes, no mail flow disruption, no parallel-run period. We connect through Microsoft Graph or the Google Workspace API, ingest your last 30 days of mail history to build behavioral baselines, and start reasoning about new mail in real time. Customers see results day one and can run alongside their existing SEG until they're ready to retire it.
No — and you wouldn't want it to. Microsoft and Google handle the volume layer (basic spam, known-bad URLs, malware signatures) extremely well. StrongestLayer sits behind them, reasoning about everything they let through. Customers typically retire their third-party SEG (Proofpoint, Mimecast) and keep Microsoft/Google native + StrongestLayer.
Pricing is custom and scales by mailbox. We don't have rigid tiers — book a demo for a deployment-specific quote.
SaaS. Email content is processed in memory by the reasoning engines and not written to long-term storage; only metadata (verdicts, reasoning traces, sender features) is retained for SOC audit. Full security questionnaire and data-handling documentation are available under NDA.
