Cybersecurity company StrongestLayer, which builds AI-native solutions to tackle email security and human risk, has officially emerged from stealth mode.
Founded by cybersecurity veterans from companies such as Proofpoint, FireEye, Mandiant, Google, and McAfee, the firm aims to redefine how organisations combat modern, AI-driven email threats.
The company has secured $5.2m in seed funding. The round was led by Sorenson Capital, with participation from Recall Capital. The investment underscores rising concern about the rapidly evolving capabilities of generative AI in cybercrime.
StrongestLayer’s platform is specifically built to address the growing use of large language models (LLMs) in cyberattacks. Unlike traditional email security tools, which depend on pattern recognition and static rules, StrongestLayer uses LLM-native detection to understand malicious intent—even when it is carefully disguised through language manipulation. This AI-native approach enables both threat detection and employee training to respond to the specific tactics targeting their organisation.
The funding will support StrongestLayer’s mission to advance its LLM-native cybersecurity platform, further develop its proprietary TRACE (Threat Reasoning AI Correlation Engine), and expand the company’s operations. TRACE integrates multiple AI engines and replicates the analysis capabilities of thousands of human security analysts, allowing organisations to stay ahead of increasingly sophisticated phishing schemes.
The company’s predictive detection capabilities have already identified and neutralised 3.9 million fake company websites within the last year—illustrating the platform’s effectiveness in pre-empting complex phishing campaigns.
StrongestLayer CEO and co-founder Alan LeFort said, “We’re witnessing an irreversible transformation in the threat landscape. Security experts predict that by 2026-2027, AI-generated attacks will become the dominant form of email threats, growing from today’s small percentage to over 20% of all attacks. When sophisticated threats that once required nation-state capabilities can now be created by anyone with AI tools, pattern-matching systems don’t just become ineffective—they become obsolete. Our LLM-native approach isn’t just catching today’s threats—it’s architected for the AI-orchestrated threat landscape that is here and growing.”
Sorenson Capital partner Ken Elefant said, “Traditional email security was built for a world where attackers needed technical skills to craft convincing phishing emails. Now that AI can generate personalised, sophisticated attacks at scale, we need a fundamentally different approach. Alan and his team have deep experience with the limitations of pattern-based detection, and their LLM-native platform is the first solution we’ve encountered that can truly reason through malicious intent, like a human analyst, but with the speed and scale of a superpowered machine.”
Recall Capital general partner Somrat Niyogi added, “The email security market is massive, but dominated by legacy platforms that weren’t built for this AI-driven threat landscape. Alan, Riz, Josh, and the StrongestLayer team deeply understand where the gaps are—and they’re taking a fresh, LLM-native approach that’s exactly what this market needs right now.”
This marks StrongestLayer’s first publicly disclosed funding round, with no previous investment amounts announced.
