What is SimSpace?

SimSpace provides a sophisticated cyber range and AI testing environment designed to validate, operationalize, and develop AI agents in partnership with human operators within a digital replica of a production environment. Security teams can continuously evaluate both human and agent defenses against realistic user behaviors, simulated attacks, and threats posed by large language models, preventing potential issues from affecting actual production systems. The platform recreates authentic infrastructure, tools, data architectures, workflows, and operational playbooks, permitting organizations to measure agent performance in genuine operational settings rather than depending solely on simulated environments. SimSpace not only assesses the final outcomes but also analyzes the full trajectory of an agent's actions, encompassing tool usage, escalation points, and error recovery, which helps identify agents that may produce correct results for the wrong reasons. Furthermore, the validation process can run continuously via automated, API-driven workflows customized for CI/CD environments, ensuring that models and playbooks evolve in line with changes. This all-encompassing strategy empowers organizations to uphold a high state of preparedness against emerging threats and enhances their resilience in the face of evolving cyber challenges. Ultimately, SimSpace equips teams with the necessary insights to refine their defenses continually.

What is Adaptive Security?

Adaptive Security was founded in 2024 by seasoned entrepreneurs Brian Long and Andrew Jones. Since inception, the company has raised over $50 million from top-tier investors including OpenAI, Andreessen Horowitz, and executives from Google Cloud, Fidelity, Plaid, Shopify, and other industry leaders. Adaptive defends organizations against sophisticated, AI-driven cyber threats such as deepfakes, vishing, smishing, and spear phishing. Its next-generation security awareness training and AI phishing simulation platform enables security teams to deliver ultra-personalized training that adapts to each employee’s role, access level, and exposure. This training leverages real-time open-source intelligence (OSINT) and features highly convincing deepfake content—including synthetic media of a company’s own executives—to mirror real-world attack vectors. Through AI-powered simulations, customers can continuously assess and improve organizational resilience. Hyper-realistic phishing tests across voice, SMS, email, and video channels evaluate risk across every major vector. These simulations are fueled by Adaptive’s AI OSINT engine, giving teams deep visibility into how attackers might exploit their digital footprint. Today, Adaptive serves global leaders like Figma, The Dallas Mavericks, BMC Software, and Stone Point Capital. With an industry-leading Net Promoter Score of 94, Adaptive is redefining excellence in cybersecurity.
