eBPF-Powered WAF in Rust for High-Performance Application Security
Shibuya is a next-gen WAF built in Rust using eBPF for line-rate performance and ML for intent-based detection. The product addresses a real pain point: traditional WAFs sacrifice performance for accuracy or vice versa. Signal from HN shows 22 upvotes and 18 comments, indicating developer interest. However, the security market is conservative with long sales cycles and entrenched cloud competitors.
Problem Statement
Current WAFs force a tradeoff: legacy solutions like ModSecurity are slow and produce high false positives, while cloud WAFs introduce latency and data sovereignty concerns. Companies either accept performance hits or run minimal protection.
The Idea
A WAF for security-conscious engineering teams who need protection without performance degradation, built on modern kernel infrastructure.
Why Now
eBPF has matured into production-ready technology (used by Cloudflare, Datadog, Isoolate), Rust adoption in infrastructure is accelerating, and ML for security detection is becoming mainstream. The convergence of these trends makes now the right time for a modern WAF architecture.
Target User
Security engineers, DevOps leads, and platform engineers at mid-market to enterprise companies running custom web applications
Target Market
Companies with performance-sensitive web applications in fintech, e-commerce, and technology sectors who need protection but cannot tolerate the latency of traditional WAFs

License Optimization Advisor and Cost Allocation Engine for Okta Identity Cloud
Buyer reviews for Okta Identity Cloud consistently highlight cost management gap friction, specifically: Per-user pricing with add-on modules compounds quickly. SSO + MFA + Lifecycle Ma; Can't right-size licenses per user role. An intern and a C-suite exec pay the sa. This pain is concentrated among IT teams managing Okta licensing costs as workforce identity needs grow and creates demand for a focused tool that resolves the gap without requiring a platform switch. The Security category has matured enough that users have committed to Okta Identity Cloud as infrastructure, making adjacent tooling more viable than platform replacement.

PrivacyPal uses 'Privacy Twins' to protect data sent to AI tools. The deeper enterprise problem is Shadow AI: employees paste sensitive company data into ChatGPT, Claude, and Gemini without approval, creating data leakage risks. An enterprise-grade Shadow AI monitor that detects sensitive data in AI tool inputs, enforces DLP policies, and provides usage visibility would address the #1 AI security concern for CISOs.
View opportunitySecurityAI Security Layer for Autonomous Agent Workflow Protection
As AI agents gain autonomous capabilities (browsing, coding, file access, API calls), they become attack vectors for prompt injection, data exfiltration, and unauthorized actions. Existing security tools monitor human user behavior, not agent behavior. A security layer that monitors agent actions in real-time, detects anomalous behavior, and blocks unauthorized operations before they execute protects enterprises deploying autonomous agents.
