Three things CISOs ask before the call.
More questions →What access do you need?
API access through Microsoft Graph or the Google Workspace API, with the permissions needed to read and quarantine mail. No MX changes, no agents, revocable in one click from your admin console.
What if StrongestLayer goes down?
Your mail keeps flowing. We sit behind Microsoft or Google, not in front of them, so delivery never depends on us.
Live status →More questions CISOs ask.
What is StrongestLayer?
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.
How is StrongestLayer different from Proofpoint, Mimecast, or Abnormal?
Gateways rely on signatures, sender reputation, and rules. ML platforms flag what looks statistically unusual. Both were built before generative AI made every phishing email unique. StrongestLayer is built on LLMs from day one and reasons about what an email is trying to accomplish. At a 5,000-seat customer, 0.4% of alerts were false positives.
How long does deployment take?
About 15 minutes via API. No MX record changes and no mail flow disruption. We connect through Microsoft Graph or the Google Workspace API and start reasoning about new mail right away. There is no learning period.
Do we have to rip and replace our existing email security?
No. Most customers start alongside their gateway so they can see what it is missing, then decide whether to retire it.
Does StrongestLayer replace Microsoft Defender or Google Workspace protection?
No, and you would not want it to. Microsoft and Google handle the volume layer well. StrongestLayer sits behind them and reasons about everything they let through.
Who founded StrongestLayer?
Alan LeFort (CEO), Josh Bass (CPO) and Muhammad "Riz" Rizwan (CTO): operators who built and scaled the last generation of email, human-risk and threat-detection security at Proofpoint, McAfee, Google, Mandiant and FireEye. Founded in 2024 and backed by $9.3M in funding: a seed round led by Sorenson Capital with Recall Capital, and a 2026 round led by Inovia Capital.
