Securing Agentic AI: Visibility and Protection for MCP Servers and A2A Traffic

AI agents aren’t just talking, they’re taking actions. They’re booking transactions, pulling sensitive data, and chaining tools together to get work done. As enterprises embrace these agents, protocols like the Model Context Protocol (MCP) and Agent-to-Agent (A2A) are enabling powerful new capabilities, but also creating invisible ecosystems of API-driven agent activity that traditional security tools can’t see or control.

You Can't Have AI Security Without API Security

For most leadership teams, the question is no longer if they’ll use AI, but how to turn it into measurable business value. Success hinges on the APIs that feed, govern, and scale AI initiatives — and whether your strategy is built for speed, security, and cost efficiency. From accelerating product development to delivering real-time customer experiences, the business case for AI is clear. But without the right API strategy, AI initiatives risk falling short — driving up costs, creating compliance gaps, and limiting ROI.

Update on React Server Components RCE Vulnerability (CVE-2025-55182 / CVE-2025-66478)

The attack landscape has been dynamic following the disclosure of the React Server Components RCE vulnerability. New information has emerged regarding the initial Proof-of-Concept exploit, as well as improved detection methods, exploitation mechanics observed in the wild, and rapidly growing attack activity. This update summarizes the changes and observations we have made across Wallarm customers.

Agentic AI Security: The Emerging Fourth Pillar of Cybersecurity

For decades, cybersecurity has been organized around three dominant pillars: endpoint security, network security, and cloud security. These domains have shaped technology categories, vendor ecosystems, and enterprise budgets. They have matured into multi-billion-dollar markets, each responding to successive waves of digital transformation. However, a tectonic shift is underway.

API Security vs Application Security: What's the Difference & Best Practices 2026

Over the past few years, APIs have quietly become the front door to your most critical data and workflows, flipping security ownership on its head. Accountability and ownership of both API and Application security have shifted from your central infra and network teams to product, platform, and engineering squads that ship new APIs every week, and well, sometimes every day. This is where CISOs and CTOs feel the tug strengthening from both sides.

Critical vLLM Flaw Exposes the Soft Underbelly of AI Infrastructure

While the world worries about "jailbreaking" LLMs or preventing them from hallucinating, a critical new vulnerability has just reminded us of a fundamental truth: AI is just software, and software has bugs. A newly discovered critical flaw (CVE-2025-62164) in vLLM, one of the most popular libraries for serving large language models, allows attackers to achieve Remote Code Execution (RCE) or crash servers simply by sending a malicious API request. This isn't a failure of the AI model.

The Most Dangerous Blind Spot in SaaS Architecture #saas #saassecurity #cloudsecurity #apisecurity

When data flows between two critical SaaS tools (like Salesforce and a CRM chatbot), you have zero visibility into that traffic. This leaves a gaping hole for attackers to exploit Business Logic Abuse. Since you can't see the traffic, you cannot monitor the attack. The Solution? Rigorous Vendor Management. Control Your Own Keys! The responsibility to protect your sensitive data is always yours, even in the cloud.

Wallarm Halts Remote Code Execution Exploits: Defense for Vulnerable React Server Component Workflows

On December 3, 2025, React maintainers disclosed a critical unauthenticated remote code execution (RCE) vulnerability in React Server Components (RSC), tracked as CVE-2025-55182. A working PoC was released publicly, and Wallarm immediately began observing widespread exploitation attempts across customer environments.
