Akto is a rapid, open-source API security platform that enables users to set up in just one minute. Security teams utilize Akto to keep an ongoing inventory of APIs, assess them for vulnerabilities, and identify issues during runtime. The platform includes tests for all categories from the OWASP Top 10 and HackerOne Top 10, such as Broken Object Level Authorization (BOLA), authentication flaws, Server-Side Request Forgery (SSRF), Cross-Site Scripting (XSS), and various security configurations. With its robust testing engine, Akto conducts a range of business logic tests by analyzing traffic data to discern API usage patterns, effectively minimizing false positives. Additionally, Akto supports integration with a variety of traffic sources, including Burpsuite, AWS, Postman, GCP, and various gateways, enhancing its usability across different environments. This adaptability makes Akto a valuable tool for ensuring the security of APIs in diverse operational settings.

Shifting from development to production, as well as from conventional data engineering to artificial intelligence, necessitates the safeguarding of various environments, pipelines, tools, and open-source components that form the backbone of your data and AI supply chain. It is crucial to consistently identify, avert, and correct security and compliance weaknesses in AI prior to their deployment in production. Furthermore, real-time monitoring of AI applications facilitates the identification and counteraction of adversarial AI attacks while ensuring that specific application guardrails are maintained. Noma seamlessly integrates throughout your data and AI supply chain and applications, delivering a comprehensive overview of all data pipelines, notebooks, MLOps tools, open-source AI components, and both first- and third-party models alongside their datasets, which in turn allows for the automatic generation of a detailed AI/ML bill of materials (BOM). Additionally, Noma continuously detects and provides actionable insights for security challenges, including misconfigurations, AI-related vulnerabilities, and the improper use of non-compliant training data across your data and AI supply chain. This proactive strategy empowers organizations to significantly improve their AI security framework, ensuring that potential risks are mitigated before they have a chance to affect production. In the end, implementing such strategies not only strengthens security but also enhances overall trust in AI systems, fostering a safer environment for innovation.

AIM Intelligence is an all-encompassing AI security platform that ensures oversight of AI systems as they make decisions, utilize APIs, and execute tasks in real-world business settings. It takes a proactive stance against potential threats to AI, preventing malicious actors from exploiting weaknesses by implementing real-time guardrails to ensure compliance with corporate policies. This platform features a diverse range of integrated solutions such as automated AI red teaming, prompt guardrail enforcement, and expert consulting on security frameworks, which aid organizations in managing complex AI risks during both development and operational stages. Stinger plays a crucial role in enhancing AI vulnerability detection by replicating numerous attack scenarios, enabling extensive agentic red teaming that goes beyond simple prompt-level threats, and performing assessments across various modalities including text, image, audio, video, and even physical AI, while offering customized vulnerability evaluations based on specific business logic. In parallel, Starfort ensures real-time enforcement of AI guardrails by detecting and protecting sensitive information like personally identifiable information (PII) and trade secrets while monitoring for irregular API requests made by autonomous agents. By integrating these critical components, AIM Intelligence empowers organizations with essential tools to foster a secure and compliant AI landscape, ultimately promoting trust in AI technologies. As businesses increasingly rely on AI, the importance of robust security measures becomes paramount.
