Axonius Co-Founder Dean Sysman Joins Lasso Security Board of Directors to Help Define the Future of AI Security

Industry-leading cyber entrepreneur and category creator to advise AI security startup as enterprises and federal agencies race to safely adopt AI at scale

TEL AVIV, Israel–(BUSINESS WIRE)–#AISecurity–Lasso Security, the AI security platform enabling secure AI adoption at enterprise scale, today announced that Dean Sysman, co-founder and executive chairman of Axonius, has joined its Board of Directors. Sysman will advise Lasso as it helps enterprises and federal agencies safely deploy AI agents, address emerging risks like data leakage, model abuse, rogue-agent behavior, and prompt-based attacks, and demonstrate compliance with evolving AI governance requirements.

Shared Dean Sysman, “Every company is racing to adopt AI, but we’re creating the largest attack surface in software history. Lasso is solving the foundational problem of securing AI agents at scale, with a team that has the grit, depth, and vision to define this new category. I’m honored to help write the playbook for AI security alongside Elad and this elite team.”

Sysman co-founded Axonius and served as CEO as it grew to a $2.6 billion valuation, establishing cyber asset management as a must-have security category along the way. His experience defining a new market segment, scaling a global go-to-market organization, and working closely with enterprise CISOs and federal customers will guide Lasso as it builds the foundational security layer for AI agents across modern enterprises.

Elad Schulman, CEO & Co-Founder, Lasso Security, said, “Dean’s track record of turning a novel cybersecurity idea into a global must-have category and scaling it to serve complex enterprises and federal agencies is exactly what Lasso needs as we help organizations gain visibility, enforce policies, and block AI-driven attacks without hindering innovation. We welcome Dean to our board.”

Organizations are rapidly shifting from isolated chatbots to autonomous AI agents that reason, plan, and execute multi-step workflows across sensitive systems. This creates a non-deterministic attack surface, where legacy security tools that rely on keyword scanning and regex classifiers struggle to keep pace.

Lasso’s AI Security Platform, anchored by its recently launched Intent Deputy, the industry’s first behavioral intent framework, introduces “Intent Security,” analyzing real-time agent behavior to prevent risks that legacy tools miss. Already trusted by enterprises and federal agencies, Lasso gives security teams full visibility and control over how AI is used, built, and deployed across the organization.

As a board member, Sysman will work closely with Lasso’s leadership team on product strategy, go-to-market execution, and category creation, drawing on his experience partnering with CISOs, security teams, and federal agencies at Axonius.
