Security training platform startup Herd Security Inc. today announced that it has raised $3 million in new funding to expand product development across new training categories in human resources and artificial intelligence, optimize its AI-powered video generation capabilities and grow its partnership ecosystem.

Founded in 2025, Herd Security offers an agentic AI platform built for continuous security awareness training and simulation. The company pitches itself as an alternative to static, once-a-year compliance programs that gives security and governance, risk and compliance teams a way to generate training content, scenarios and assessments that draw on organizational context and active threat intelligence.

The platform lets customers upload their policies, compliance frameworks and security data, then generate short training modules from prompts. The training is pushed out through Slack, Microsoft Teams and existing learning management systems in formats including text, video, images and conversational AI.

The company argues that the gap between the speed of evolving threats and the time required to build security habits is widening. Herd cites research from the SANS Institute that found that it can take three to five years for organizations to influence employee behavior and up to a decade to shape security culture. And Gartner Inc. has predicted that by 2028, 40% of social engineering attacks will target executives and the broader workforce.

“Security training has never been limited by expertise, but by execution,” said co-founder and Chief Executive Brandon Min. “Threats evolve daily and organizations aren’t equipping security professionals with the tools to turn what they know into relevant programs that engage employees when it matters most.”

Among existing customers is Onebrief Inc., whose Director of Corporate IT and Security Stefany Pratt said the company has replaced long, static lectures with short microtrainings delivered directly into employee workflows.

The funding round was led by Aspiron Ventures Ltd., with Team Ignite, ForwardSlash VC, Forum Ventures, Rightside Capital and YPO also participating.

“Organizations face a new reality where threats are outpacing workforce preparedness,” said Oliver Legg, a partner at Aspiron Ventures. “Security training has not evolved for this shift, but Herd is addressing that problem by reinventing how it is operationalized without the usual friction.”
