What is Operator by Planck Proof?

Operator by Planck Proof serves as a robust API penetration testing solution tailored for agentic applications. By inputting your OpenAPI specification along with credentials for various roles, it thoroughly investigates all operations associated with those roles and tenants, identifying potential authorization vulnerabilities such as BOLA, BFLA, and BOPLA, alongside other issues like broken authentication, injection flaws, mass assignment, and business-logic exploits, thereby connecting these vulnerabilities to outline possible attack routes. Its extensive coverage adheres to the OWASP API Security Top 10 and supports multiple API types, including REST, GraphQL, and gRPC, as well as those employed by AI agents, LLM applications, and MCP servers. Each detected vulnerability is accompanied by detailed request and response information, a CVSS score, and a runnable proof-of-concept, which your engineering team can leverage to confirm the presence of the issue and implement necessary remedies. Moreover, the tool features scope, rate, and data controls designed to safeguard operations in live environments, empowering users to manage or pause the testing agent whenever necessary. It is integrable with every deployment, allowing for the reassessment of fixes and easy transfer of findings to Jira for efficient tracking. Reports generated are comprehensive and cater to both engineering teams and auditors, ensuring adherence to compliance standards like SOC 2, PCI DSS, and HIPAA. The initial scan is offered at no charge, while Pro and Enterprise pricing is based on the number of API endpoints evaluated, providing organizations with the flexibility to select a plan that aligns with their specific testing requirements. This versatility in pricing and functionality makes Operator a compelling choice for enhancing API security across varied environments.
