Herd Security, an agentic AI platform designed for continuous security training and simulation, has closed a $3m funding round backed by strategic investor Aspiron Ventures alongside Team Ignite, ForwardSlash VC, Forum Ventures, Rightside Capital, and YPO.
The fresh capital will be directed towards expanding product development into new training categories spanning HR and AI, enhancing the platform’s AI-powered video generation tools, and broadening the company’s network of partners.
The fundraise comes at a time when AI-driven social engineering threats are evolving faster than traditional compliance programmes can keep up. Research from Gartner suggests that by 2028, four in ten social engineering attacks will be directed at executives and employees more broadly, placing mounting pressure on enterprises to rethink how they approach security awareness. Compounding this challenge, data from the SANS Institute indicates that it can take organisations between three and five years to shift employee behaviour, and up to a decade to embed a lasting security culture.
Herd Security’s platform targets security and governance, risk, and compliance (GRC) teams, offering a way to move beyond static, one-size-fits-all training programmes. Instead of periodic exercises that fail to reflect live threat conditions, the platform enables teams to build tailored training content, run simulations, and develop assessments grounded in real-time threat intelligence and specific organisational context.
Users can pull in policies, compliance frameworks, and security data — all of which the platform automatically interprets and refreshes when changes occur. Training can be created in seconds using targeted prompts and delivered across existing workplace tools in multiple formats, including text, video, image, and conversational AI.
Herd Security CEO and co-founder Brandon Min said, “Security training has never been limited by expertise, but by execution. Threats evolve daily and organisations aren’t equipping security professionals with the tools to turn what they know into relevant programmes that engage employees when it matters most. Herd removes this barrier so teams can continuously put their knowledge into action without added resources, creating everyday awareness that strengthens human defence to match the speed and scale of emerging risks.”
Aspiron Ventures partner Oliver Legg said, “Organisations face a new reality where threats are outpacing workforce preparedness. Security training has not evolved for this shift, but Herd is addressing that problem by reinventing how it is operationalised without the usual friction. The company’s recognition as a finalist in last year’s Okta Startup Challenge was an early signal of momentum, and our investment is all about accelerating that progress.”
OneBrief director of corporate IT & security Stefany Pratt said, “Herd has truly transformed our approach to security training. We’ve replaced long, static lectures with short, timely microtrainings that fit directly into employee workflows. This has made it easier to reinforce positive security behaviours and cultivate a more proactive culture with training that feels relevant and engaging.”
