Enhancing API Security with AI/ML: A Critical Imperative

Imagine this: A major retailer suffers a massive data breach. Customer credit card information, social security numbers, and purchase histories – all exposed. The culprit? It is not a sophisticated phishing attack but a vulnerability in a seemingly innocuous application programming interface (API).

This scenario is not far-fetched. In today's hyper-connected world, APIs are the invisible threads that weave together our digital experiences. APIs facilitate seamless data exchange from the apps on your phone to the systems that power global commerce. However, this interconnectedness also creates a significant security risk.

According to the 2024 Gartner API Strategy Survey, 82% of respondents stated that their organizations leveraged APIs internally, while another 71% reported using APIs provided by third-party vendors such as SaaS providers.[i]

The API-first paradigm will evolve as technology service providers (TSPs) globally lead Gen AI adoption across application interfaces. Gartner predicts that by 2026, more than 30% of the demand surge in APIs will be driven by AI and tools using large language models (LLMs).[ii]

Organizations need more than just an API gateway strategy to address the demand to deliver high-quality APIs. Proper tooling, processes, and enablement are indispensable to developing and scaling next-generation APIs. And this is where significant cost is involved. Developing, scaling, and securing APIs require substantial investment – not just in terms of budget but also in the effort and time involved in API development processes.

The Dilemma - Striking a Balance Between API Cost and Security

Organizations invest millions to develop APIs that connect complex systems and power digital ecosystems. While significant resources are allocated to ensuring functionality and compatibility through rigorous testing, API security often takes a back seat. This imbalance creates vulnerabilities that threat actors eagerly exploit.

APIs can become an easy attack vector due to their direct access to internal system resources and over-permissioned configurations. If not secured rigorously, APIs can become entry points for scathing cyberattacks, resulting in serious financial and operational risk. The bad news is that API breaches have become increasingly commonplace. According to a recent study, 84% of respondents reported having experienced an API security incident over the past twelve months. This marks the third straight year of increased attacks and an all-time high, up from 78% in 2024.[iii] Sadly, these API security incidents have substantial associated costs. Research reveals that 47% of organizations that witnessed an API security incident last year reported more than $100,000 in remediation costs, and 20% said costs exceeded $500,000.[iv]

Strengthening API Security with AI and ML

In an era characterized by sophisticated security threats, conventional API security measures are bound to fall short. This is why, to counter modern threats, organizations need to resort to modern counter-measures reinforced by technologies like Artificial Intelligence (AI) and Machine Learning (ML). These technologies can help transform how an organization approaches API security by:

• Automating API discovery: Organizations often fail to seamlessly track all functioning APIs within an ecosystem, resulting in the proliferation of ‘shadow APIs’ that usually go unmonitored and undocumented. AI-driven tools can automatically discover and catalogue the APIs in the ecosystem, ensuring none are left exposed to external threats.
• Detecting real-time threats: With large amounts of data, ML algorithms can recognize trends and anomalies indicating a potential threat. Organizations could then begin working on proactive positions regarding API security, reducing the potential for breaches.
• Streamlining compliance checks: AI-driven tools can discover instances of sensitive & PII data, and automate cumbersome compliance checks, reducing the time & effort required for manual process.
• Employing predictive analytics: Using ML models on historical data would allow them to predict possible threats and suggest preventive action, which can help organizations anticipate and prevent developing risks.
• Runtime testing and intelligent discovery: As API ecosystems grow, locating and integrating the correct API can become challenging. AI can help streamline this by assisting organizations in automatically categorizing APIs based on functionalities and relevance. Additionally, AI solutions can help organizations drive runtime testing that enables threat detection and response in real-time. These tools can proactively identify vulnerabilities before they are exploited by simulating attacks and analyzing runtime behavior.  
• Prioritizing remediation efforts: AI reduces noise by filtering out false positives and prioritizing vulnerabilities based on severity, exploitability, and business impact. This enables risk-based mitigation, ensuring critical threats are addressed first while improving response efficiency and reducing security exposure.

From Risk to Resilience: Why API Security Is a Business Imperative

APIs are essential to digital transformation, making their security a critical business priority. The costs of neglecting API security far exceed those of robust safeguards.
