Nemesis vs. Adaptive Security

Nemesis from Persistent Security Industries is a next-generation Breach and Attack Simulation (BAS) solution built to give organizations continuous visibility into their true security posture. Using atomics—individual attacker techniques—and scenarios that chain these techniques into real-world simulations, Nemesis tests defenses against a wide range of advanced threats. The platform provides realistic, repeatable simulations that uncover misconfigurations, overlooked vulnerabilities, and ineffective security controls. Its automation capabilities allow security teams to schedule assessments, compare results over time, and track improvements with minimal manual effort. Nemesis also generates detailed, evidence-based reports that streamline compliance processes and make it easier to communicate security effectiveness to executives and boards. By validating ransomware readiness, SOC performance, and cloud security controls, it empowers organizations to prioritize resources more effectively. Integrations with existing tools and infrastructure ensure Nemesis becomes a natural extension of the security stack. Customers have reported measurable outcomes, including up to 60% reduced ransomware costs and 80% less time spent preparing board-level updates. Backed by endorsements from cybersecurity leaders, Nemesis has earned its reputation as one of the most advanced BAS solutions available today. Ultimately, it shifts cybersecurity from reactive assumptions to proactive validation, ensuring defenses hold up when it matters most.

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.
