Performing prompt injection attacks has always been a risk that was not quantified until Anthropic introduced a new approach. By measuring prompt injection across different agent surfaces, security teams can now make more informed decisions. While OpenAI and Google provide benchmark scores and relative safety improvements, Anthropic’s detailed breakdown of attack success rates sets a new standard for transparency.
Understanding the Importance of Surface-Level Differences
Anthropic’s release of Opus 4.6 has shed light on the significance of surface-level differences in determining enterprise risk. With detailed data on attack success rates, security leaders can now assess the vulnerability of their systems more effectively. OpenAI and Google offer valuable insights, but Anthropic’s approach sets a new benchmark for transparency and accountability.
The Significance of Vendor Disclosures
Comparing the disclosure practices of Anthropic, OpenAI, and Google reveals the importance of granular vendor disclosures. While Anthropic provides per-surface attack success rates and attack persistence scaling data, OpenAI and Google offer more limited information. Third-party testing further emphasizes the need for detailed disclosures to ensure the security of AI systems.

Key Choice for Security Leaders
Security leaders should prioritize transparency and accountability when evaluating AI agent deployments. By requesting detailed attack success rates and commissioning independent red team evaluations, they can enhance the security of their systems. Validating agent security claims against independent results is crucial for ensuring the safety and reliability of AI systems.
