Summary:
Timothy De Block is joined by Sam Chehab to unpack the key findings of the 2025 Postman State of the API Report. Sam emphasizes that APIs are the connective tissue of the modern world and that the biggest security challenges are rooted in fundamentals. The conversation dives deep into how AI agents are transforming API development and consumption, introducing new threats like "rug pulls" , and demanding higher quality documentation and error messages. Sam also shares actionable advice for engineers, including a "cheat code" for getting organizational buy-in for AI tools and a detailed breakdown of the new Model Context Protocol (MCP).
Key Insights from the State of the API Report
API Fundamentals are Still the Problem: The start of every security journey is an inventory problem (the first two CIS controls). Security success is a byproduct of solving collaboration problems for developers first.
The Collaboration Crisis: 93% of teams are struggling with API collaboration, leading to duplicated work and an ever-widening attack surface due to decentralized documentation (Slack, Confluence, etc.).
API Documentation is Up: A positive sign of progress is that 58% of teams surveyed are actively documenting their APIs to improve collaboration.
Unauthorized Access Risk: 51% of developers cite unauthorized agent access as a top security risk. Sam suspects this is predominantly due to the industry-wide "hot mess" of secrets management and leaked API keys.
Credential Amplification: This term is used to describe how risk is exponential, not linear, when one credential gains access to a service that, in turn, has access to multiple other services (i.e., lateral movement).
AI, MCP, and New Security Challenges
Model Context Protocol (MCP): MCP is a protocol layer that sits on top of existing RESTful services, allowing users to generically interact with APIs using natural language. It acts as an abstraction layer, translating natural language requests into the proper API calls.
The AI API Readiness Checklist: For APIs to be effective for AI agents:
Rich Documentation: AI thrives on documentation, which developers generally hate writing. Using AI to write documentation is key.
Rich Errors: APIs need contextual error messages (e.g., "invalid parameter, expected X, received Y") instead of generic messages like "something broke".
AI Introduces Supply Chain Threats: The "rug pull" threat involves blindly trusting an MCP server that is then swapped out for a malicious one. This is a classic supply chain problem (similar to NPM issues) that can happen much faster in the AI world.
MCP Supply Chain Risk: Because you can use other people's MCP servers, developers must validate which MCP servers they're using to avoid running untrusted code. The first reported MCP hack involved a server that silently BCC'd an email to the attacker every time an action was performed.
Actionable Advice and Engineer "Cheat Codes"
Security Shift-Left with Postman: Security teams should support engineering's use of tools like Postman because it allows developers to run security tests (load testing, denial of service simulation, black box testing) themselves within their normal workflow, accelerating development velocity.
API Key Management is Critical: Organizations need policies around API key generation, expiration, and revocation. Postman actively scans public repos (like GitHub) for leaked Postman keys, auto-revokes them, and notifies the administrator.
Getting AI Buy-in (The Cheat Code): To get an AI tool (like a Postman agent or a code generator) approved within your organization, use this tactic:
Generate a DPA (Data Processing Agreement) using an AI tool.
Present the DPA and a request for an Enterprise License to Legal, Security, and your manager.
This demonstrates due diligence and opens the door for safe, approved AI use, making you an engineering "hero".
About Postman and the Report
Postman's Reach: Postman is considered the de facto standard for API development and is used in 98% of the Fortune 500.
Report Origins: The annual report, now in its seventh year, was started because no one else was effectively collecting and synthesizing data across executives, managers, developers, and consultants regarding API production and consumption.

The Winding Path to CISO: Rob Fuller's Leadership Journey
Summary:
In this episode, Timothy De Block sits down with Rob Fuller, Vice President of Cybersecurity, for a candid discussion about Rob's journey into cybersecurity leadership. Rob shares his unique path from the Marine Corps to a Fortune 10 company, revealing the struggles and lessons learned along the way. The conversation delves into the critical role of visibility, the importance of continuous learning, and invaluable advice for those aspiring to leadership roles in the security industry.
Key Takeaways
From "Noob" to VP: Rob shares the humorous origin of his online handle, "Mubix," which came from a mistyped name in an MMORPG. He recounts his initial struggle to transition into leadership, including turning down a director position at General Electric due to perceived lack of experience, until his wife reminded him of his past leadership roles in the Marine Corps and community groups.
Leadership is a Different Career Path: Rob emphasizes that moving into a leadership role requires a complete mindset shift and is a distinct career path from a technical one. He learned a crucial lesson about career advancement: while diligence and relationships are important,
visibility is paramount. He also notes the importance of a manager understanding they are part of two teams: their direct reports and their peer group of fellow leaders.
The Value of Continuous Learning: Rob recommends the book Surrounded by Idiots by Thomas Erikson to understand different communication styles and the importance of adapting in management. He is also actively pursuing advanced degrees and certifications like CISSP and NACD to meet the requirements for director and CISO roles in large companies.
Aspiring to CISO: Rob's ultimate goal is to become a CISO, as he believes it's the only role that allows for the implementation of comprehensive, widespread cybersecurity solutions.
Advice for Career Starters: For those looking to enter cybersecurity, Rob and Timothy advise being open to any IT job, including the help desk, as an entry point. They also stress the importance of actively participating in local groups and conferences like hacker meetups and B-Sides, as this networking and volunteering can significantly increase your chances of getting hired.
Blue Team Experience is Gold: Both agree that blue team (security operations) experience is highly valuable for aspiring pentesters, as it teaches crucial skills like scripting, queries, networking, and evasion techniques that make them more effective in red team roles.
