As Subramaniam explains, \u201cAI agentic systems, which autonomously access APIs to perform tasks, complicate API security by expanding the attack surface, enabling dynamic and unpredictable interactions, and amplifying existing vulnerabilities through high-speed, automated actions.\u201d Preventing unauthorized access by agents will require more granular control and more time-bound role-based access control (RBAC)<\/a>.<\/p>\n

Other API risks stem from the broader software supply chain. In 2025, JPMorganChase CISO Patrick Opet published an open letter<\/a> about diminishing standards for SaaS providers, writing that the SaaS delivery model is \u201cquietly enabling cyber attackers\u201d and creating a \u201csubstantial vulnerability that is weakening the global economic system.\u201d<\/p>\n

Third-party API consumption can open an organization to sensitive data exposure. According to Gartner, 71% of organizations use APIs provided by third parties such as SaaS vendors, making third-party APIs another major risk vector.<\/p>\n

\u201cFor third-party APIs, we already require vendor security reviews and contractual security assurances,\u201d says Fortitude Re\u2019s Franklin, noting that this is part of a broader SaaS security program that provides visibility into the SaaS systems employees use.<\/p>\n

The onus, however, is also on the consuming organization to implement better token-handling processes to secure API connections to SaaS platforms. This is especially important, as developers are often reckless with API keys and secrets. In 2024, Escape discovered 18,000 API secrets and tokens<\/a> floating around on the open web.<\/p>\n

Some CISOs are actively addressing this. \u201cOur team centralizes and encrypts all third-party credentials \u2014 API keys, tokens \u2014 within the API management layer,\u201d says Subramaniam. \u201cWe never distribute raw credentials to our internal development teams.\u201d<\/p>\n

Maintaining safe integrations requires ongoing discipline, too. \u201cWe apply the same rigor to third-party APIs: Credentials are tightly scoped, regularly rotated, and monitored for behavioral drift,\u201d adds Faxon. \u201cIf an integration begins acting outside its expected pattern, it\u2019s treated as a security event, not a technical anomaly.\u201d<\/p>\n

For Murphy, avoiding third-party API gaps requires careful vendor evaluation and tooling decisions. \u201cYou trust but verify.\u201d The same intentions must be applied to assessing API management tools, too \u2014 maintaining too many niche products increases complexity and brings scalability challenges, and requires stitching them together to obtain a cohesive API security view.<\/p>\n

\u201cThe more complexity, and the more differentiated monitoring, the higher risk you\u2019re going to mess up,\u201d says Murphy. \u201cBut, diversity in the platform is good, too, since compartmentalizing can help with a tiered aspect to security oversight.\u201d One top item in BECU\u2019s roadmap for 2026 is automating between their exposure management platform, vulnerability management platform, and security operations center, he adds.<\/p>\n

As APIs become a core aspect of modern business operations, their security risks are becoming more pronounced. \u201cEvery API misconfiguration is not just a security gap,\u201d says Faxon. \u201cIt\u2019s a business decision being executed at machine speed, without human oversight.\u201d<\/p>\n

Responding to this new era of threats requires moving beyond traditional perimeter defenses. Organizations will need new approaches to secure non-human identities \u2014 machines, bots, and agents that increasingly interact with systems and data at a business application level.<\/p>\n

\u201cThe real shift isn\u2019t just from endpoints to APIs,\u201d says Franklin. \u201cIt\u2019s from human-driven access to non-human identities like APIs, service accounts, and machine-to-machine connections.\u201d Although these identities now outnumber humans in most enterprises, he adds, they lack rigorous governance, requiring rethinking to secure this new attack surface<\/a>.<\/p>\n

The challenge is further complicated by the diversity of API environments. APIs may be distributed across multiple clouds, platforms, and locations, each with different security controls. As Mazal explains, \u201cThe challenge is that as development accelerates and the pace of innovation increases, not all APIs follow the same set of controls.\u201d<\/p>\n

Edge-based IoT APIs, for instance, may not allow the same types of traffic enforcement found in centralized environments. \u201cThe resulting gaps in interconnectivity make it difficult to manage APIs holistically and consistently across the ecosystem.\u201d For him, real-time threat monitoring and visibility of network telemetry are still essential to correct visibility gaps.<\/p>\n

Ultimately, CISOs shouldn\u2019t abandon traditional security tools. But they do need to extend security deeper into the development and design process, embedding checks early, strengthening identity-based authorization, and improving real-time visibility into business-layer interactions.<\/p>\n

By combining governance, identity controls, and visibility, CISOs can adequately prepare for the security realities of an API-driven world.<\/p>\n<\/div>\n
