Case Study: Securing AI for Cymulate - Ensuring Safe AI Adoption Across Teams

Written by: 
Prompt Security Team
August 11, 2025
  • Prompt Security delivers real-time visibility and control over Cymulate’s AI interactions.
  • By integrating Prompt Security’s monitoring capabilities, Cymulate streamlined AI governance and policy enforcement without disrupting employee workflows.
“We needed to safely enable AI use across the company without losing visibility or control. Prompt Security gave us exactly that: purpose-built, real-time protection for AI interactions with minimal disruption." - Avihai Ben-Yossef, CTO at Cymulate

Cymulate is a leading provider of cloud-based cybersecurity solutions, offering a platform that helps organizations continuously test, validate, and enhance their defenses against evolving cyber threats. Rapidly deployable and scalable, Cymulate’s platform empowers security teams to validate defenses using realistic, intelligence-driven simulations aligned with industry frameworks.

As AI adoption surged across Cymulate’s internal teams, so did the need for comprehensive visibility and stringent controls over AI interactions. Cymulate identified the necessity for a solution that would enable secure and controlled AI adoption company-wide. Prompt Security emerged as the ideal solution, providing real-time, targeted protection for AI interactions with minimal disruption.

Securing Cymulate's AI Environment

AI technology presents both significant opportunities and notable challenges, particularly in areas of governance, transparency, and live intervention. Cymulate needed full visibility into AI prompts and responses, as well as a way to prevent exposure of sensitive data. Prompt Security’s browser extension provided full session activity monitoring and prompt-level filtering, enabling the company to detect sensitive inputs and redact or block them before they were submitted.

Prompt Security’s dynamic policy controls allowed Cymulate to define behavior-based rules that adapt to context, ensuring appropriate controls across departments without sacrificing productivity. With continuous logging and real-time alerting, Cymulate gained the auditability and oversight needed to scale AI use safely.

Integration for Enhanced Control

Cymulate’s successful integration with Prompt Security significantly improved overall AI governance. Real-time scanning and policy enforcement quickly became essential, extending robust control across the company. Mapping user groups to policies allowed the security team to apply differentiated enforcement rules for functions like R&D, marketing, and customer success.

The solution streamlined AI security management, coached Cymulate's teams on secure AI practices in-browser, and facilitated rapid and secure adoption across the organization.

Ensuring a Frictionless User Experience

Prompt Security’s lightweight and flexible deployment meant employees could continue using their preferred tools and browsers, like Chrome, Safari, and Arc, without interruption. The platform’s low-latency performance ensured that AI interactions remained fast and responsive, preserving the seamless experience employees expected.

"Prompt Security let us roll out AI safely across teams without friction," Avihai Ben-Yossef, CTO at Cymulate, emphasizes. "It has improved our security posture, accelerated product development, and educated our employees on secure AI practices."

‍Measuring AI Governance Success

Cymulate measures the success of its AI governance by tracking reductions in high-risk prompts, increased policy coverage, and sustained employee productivity. With Prompt Security in place, the company has enabled safe, scalable AI adoption without compromising security or compliance.

Avihai concludes, "Prompt Security is a smart choice for scaling AI securely. It's practical, lightweight, and genuinely helps our teams leverage AI safely, ensuring rapid innovation without security risks."
