QShield

COSGrid QShield is an AI-powered Web Application & API Protection (WAAP) platform that defends applications and APIs against DDoS attacks, bot threats, business logic abuse, and zero-day exploits — without requiring endpoint agents. QShield combines a Web Application Firewall (WAF), L7 DDoS mitigation, bot management, and deep API discovery into a single unified platform. Its AI-powered predictive threat engine is designed to detect and stop API attacks up to 72 hours before they materialize, giving security teams proactive visibility rather than reactive response.

QShield supports multiple flexible deployment modes to fit any infrastructure: SaaS/multi-tenant, Kubernetes Ingress/Gateway (Helm-deployed with Envoy/NGINX), Sidecar/Service Mesh with mTLS, Edge/WAF mode with managed PoPs, on-premises Appliance/VM (KVM, VMware, Hyper-V), and Inline + TAP Hybrid for traffic monitoring alongside gateway enforcement. As part of COSGrid's Z3 SASE platform, QShield integrates with ZTNA, Secure Web Access, and DNS Security to deliver consistent, policy-driven protection across users, apps, and APIs enterprise-wide. Key capabilities include: AI-powered predictive threat detection (72-hour advance warning) WAF, L7 DDoS protection, and bot mitigation Full API discovery including unknown and shadow APIs Business logic abuse prevention (BOLA, workflow attacks)

Apyguard

ApyGuard is a developer-first API security testing platform that finds vulnerabilities and authorization flaws before they reach production. Unlike traffic-based tools that only see deployed APIs, ApyGuard discovers endpoints from source code, generates OpenAPI specs, and builds an API inventory — including shadow endpoints created by AI coding assistants. Using behavioral analysis, ApyGuard detects broken authentication, BOLA/BFLA authorization flaws, business-logic failures, and injection issues that schema-validation scanners miss. It covers the OWASP API Top 10, ranks findings by exploitability, and includes remediation guidance. CI/CD security gates and integrations connect it to GitHub, GitLab, Jira, Slack, and Postman, while dashboards track risk trends and findings map to OWASP, GDPR, and PCI DSS to support compliance. Built for startups and SMBs: transparent self-serve pricing, a no-card free trial, and a free VS Code extension (APIScout) that discovers endpoints locally.
