Agentic AI is reshaping the cyber threat landscape and APIs are fully in the cross-hairs as high-value targets. These intelligent, autonomous attack agents can identify, probe, and exploit API vulnerabilities at machine speed—making traditional, reactive defenses obsolete. In this new environment, organizations need proactive, automated, and deeply integrated security.
That’s why our Microsoft Security Store announcement today is so important, as it enables our enterprise customers to simplify the purchase and deployment of our API security platform and avail of its deep integrations with the Microsoft security product ecosystem to gain full visibility and control of their API security posture.
“We enforce governance and API security policies at scale and automatically remediate vulnerabilities before they can be exploited—ensuring their APIs are protected from design to production.” Jacques Declas, CEO and co-founder at 42Crunch
Integrated, End-to-End Protection
42Crunch’s deep integration with the Microsoft Security ecosystem enables a unified view of API risk, and allows security teams to see, understand, and control their API posture—from dev environments all the way to runtime—without context-switching or operational friction.
Combined with Microsoft’s Defender for Cloud and Sentinel platforms, 42Crunch augments detection and response workflows with granular API-specific insights, helping enterprises address real-time threats and long-term risk simultaneously.
Shift-Left for API Security at Scale
At the core of 42Crunch is a proactive, developer-first approach. APIs are scanned and tested early in the development lifecycle, ensuring that governance rules and security policies are applied before code ever reaches production. This “shift-left” model reduces risk exposure and aligns perfectly with DevSecOps practices.
More importantly, this model scales automatically across thousands of APIs. Vulnerabilities are not just flagged—they’re automatically remediated through policy enforcement and guided corrections, turning security from a bottleneck into a built-in safeguard.
This early, automated enforcement is critical in the age of Agentic AI, where intelligent adversaries are capable of adapting and evolving attacks in near real-time. By eliminating misconfigurations and weak spots before APIs go live, 42Crunch significantly reduces the attack surface these autonomous agents can exploit—cutting them off before they even have a chance to engage.
Precision Runtime API Threat Protection
When APIs are deployed, 42Crunch provides a deterministic protection with an API context and contract-aware API firewall that enforces behavior at the most granular level—validating everything from payload structure to data types. This is crucial in defending against Agentic AI-powered attacks that exploit any minor inconsistencies in API behavior.
Unlike traditional firewalls, our runtime protection doesn’t rely on static rules or signature-based detection. It adapts in real time to enforce the intended API contract, ensuring that any deviation—however subtle—is blocked before damage can occur.
This level of precision is exactly what’s required to combat Agentic AI systems, which can autonomously learn, mimic legitimate behavior, and iterate attacks rapidly. By enforcing strict adherence to the API contract, 42Crunch prevents these agents from gaining a foothold—delivering a defense that’s as intelligent and agile as the threats it’s built to stop.
Building for a Resilient Future
In a world where threats evolve autonomously, security must be just as adaptive. 42Crunch and Microsoft together provide a resilient, proactive defense for APIs—ensuring that enterprises stay ahead of threats, not behind them. From design to production, API security is no longer optional.
