Ask any security leader how many APIs their organization runs, and you’ll usually get a confident number. Ask them how many of those APIs are actually being called by an AI agent, a copilot, or an automated workflow right now, and the confidence tends to disappear. That gap is the problem. APIs have always outpaced the inventories built to track them; new services ship every sprint, integrations get added without a ticket, and old endpoints get deprecated without ever being switched off.

Model Context Protocol (MCP) is what turns an AI assistant into an AI agent. It’s the standardized bridge that lets models call real tools – read files, query databases, send messages, pull emails. That capability is the whole point. It’s also what makes MCP environments a target. Most deployments were scoped for what the agent needed to do. Not for what happens when that access is turned against the organization.

Nine seconds. One API call. A car rental software company’s production data was gone. That’s the headline from the PocketOS incident, and it’s the reason this story spread across engineering and security circles the way it did in late April. Two months later, the incident is no longer breaking news. But it hasn’t aged out of relevance; it has aged into a pattern.

Every enterprise deploying AI agents is building on a foundation of third-party MCP servers they don’t control, can’t verify, and barely track. The security conversation keeps focusing on the model – prompt injection, jailbreaks, hallucinations. That’s the wrong place to look. We’ve covered why that framing falls short elsewhere too – see System Prompts Are Not Security Boundaries. Business Logic Graphs Are.

Every major tournament cycle, ticketing platforms brace for a traffic spike. Most security teams plan for volume. The attack data tells a different story: the traffic that does the most damage isn’t the loudest traffic. It’s the traffic that looks like a real fan, on a real device, doing something a real fan would plausibly do, just millions of times, in a pattern no single fan ever would.

OWASP, the Open Worldwide Application Security Project, has published Top 10 lists for over two decades to help security teams prioritize the risks that matter most. The original OWASP Top 10 for web applications became the industry’s default checklist for application security. When large language models moved into production, OWASP followed with the Top 10 for LLM Applications, addressing risks like prompt injection and sensitive information disclosure in single-turn model responses.

Three weeks ago, it was ServiceNow: an endpoint that never asked who was calling, exposing customer data to anyone who asked. This time it’s Oracle PeopleSoft, exploited at scale by the threat actor ShinyHunters. Two platforms, two different vendors, the same root failure: an endpoint that skipped the one question it existed to ask. That’s not a coincidence you write off as bad luck at two companies.

AI systems are starting to do more than generate answers. Across customer support, IT operations, software development, and internal business workflows, organizations are deploying AI agents that can retrieve information, use tools, interact with applications, and complete tasks with limited human involvement. This shift is happening quickly. According to a McKinsey Report, 62% of organizations are already experimenting with AI agents, while 23% are actively scaling them across parts of their business.

A human employee who wants to delete a customer record, issue a refund, or push a config change has to ask, click, and confirm. An AI agent doing the same thing can plan, decide, and execute the action in one pass, often through a tool it picked itself, in a sequence no one explicitly approved. That shift, from systems that respond to systems that act, is why most application security stacks fall short the moment agentic AI enters the picture.

Not all API discovery tools solve the same problem. Some help teams discover APIs once. Others help maintain a live inventory as APIs change across cloud services, microservices, third-party integrations, and increasingly, AI-driven applications. That is where continuous API discovery stands apart. In this guide, we compare the top platforms using shared capability tags instead of forcing each tool into a single “best for” category.

Preventing next generation applications against complex API and application attacks requires deep understanding of application behaviour, API structure, interaction and sequencing, understanding of user behaviour, contexts, and intents, flow of sensitive data in the application etc. Such deep understanding can only be achieved when a product is built grounds up to address the very needs of the next-generation applications.

We are in an era of unprecedented connectivity and data growth. Data is being created and shared at the fastest pace ever. Organizations are adding new APIs to facilitate faster exchange of data. For security leaders and practitioners, this presents new and daunting challenges with the massive volume of data and new pathways to oversee, new threats to stay ahead of, and regulatory complexities to navigate. Security leaders must maintain visibility of data, manage user access to data, and enforce strong security and privacy controls.

During our various customer interactions, we often discuss how Appsentinels solution is different compared to a Web Applicaton Firewall (WAF) in protecting against API's attack. The core difference is that Appsentinels API Security Platform knows the context of what is it protecting while unfortunately WAF's don't. Let me explain why I am saying this and why this is important.

In the digital age, business leaders see software teams as core to the business and are demanding them to innovate faster in response to market and competitive demands. Organizations are on path of fast iteration - experimenting with new products or features, gauge customer feedback, adopt or drop and move to the next thing. The pace of change is not an option but existential for organizations. Organizations that can adapt will gain market shares and organizations that cannot, will cease to exist.

In 2019, OWASP released first version of API Security Top 10. Like the omnipresent OWASP Top 10, the API Security Top 10 delivers a prioritized list of the most critical application security issues with a focus on the APIs. In this whitepaper, we would like to share an overview of the API top 10 with comparisons to the OWASP top 10 for web applications and break any false sense of security by seeing similarities in the list.

During our various customer interactions, customers using Dynamic Application Security Testing (DAST) or Interactive Application Security Testing (IAST) often ask how AppSentinels solution is different compared to their existing tool: The core difference is AppSentinels API Security Platform understands the context of the Application it is protecting while DAST/IAST products unfortunately don't. Let me explain why I am saying this and why this is important.
