Security for New Agentic Platforms, Extensions, Apps & Engines
Production AI agent systems break traditional perimeter security models. We architect deterministic defenses around non-deterministic LLMs, browser extensions (Manifest V3), and high-throughput cloud bastions across Cloudflare, Google Cloud, and Microsoft Azure.
Autonomous AI Sentinel
Xion — Next-Frontier AI Security Agent
Non-deterministic LLMs cannot be trusted to self-police. Xion is an autonomous runtime sentinel that acts as a continuous firewall between users, frontier model providers, tool calling hooks, and core databases.
Prompt Injection Defense
Pre-inference semantic evaluation filters indirect prompt injections, jailbreaks, hidden instructions in crawled documents, and token spoofing before input hits the context window.
MCP Tool Sandboxing
Model Context Protocol (MCP) server calls run in isolated V8 sandboxes with strict parameter verification, least-privilege scoping, and read-only protections against filesystem traversal.
Egress & Drift Firewall
Autonomous runtime monitoring inspects every outbound HTTP call and model response to prevent data exfiltration, secret leakage, hallucinated URLs, and unapproved API interactions.
Deterministic Policy Wrappers
State transitions, database mutations, and monetary transactions cannot execute without passing strict cryptographic assertions and cryptographic schema validation.
Multi-Cloud Fortification
Hardened Across Cloudflare, Google Cloud & Microsoft Azure
True security isn't a single vendor lock-in. We weave the best native security layers of the three leading cloud ecosystems into one cohesive shield.
Zero Trust & Edge Shielding
- ✓Cloudflare Access: Identity-aware ZTNA replacing legacy corporate VPNs.
- ✓Turnstile: Invisible, privacy-preserving CAPTCHA stopping bot abuse.
- ✓API Shield: OpenAPI schema validation blocking rogue parameter payloads.
- ✓Smart Shield: Origin IP masking and automated tiered DDoS absorption.
App Check & Workload Identity
- ✓Firebase App Check: Cryptographic device attestation (DeviceCheck, reCAPTCHA Enterprise).
- ✓Cloud Armor: Machine-learning powered DDoS and OWASP Top 10 mitigation.
- ✓Workload Identity: Zero long-lived service account keys via federated tokens.
- ✓Secret Manager: Hardware-encrypted API keys with audit logging.
Entra ID & Key Vault HSM
- ✓Microsoft Entra ID: Conditional access policies, MFA, and continuous session tokens.
- ✓Key Vault HSM: FIPS 140-2 Level 3 cryptographic isolation for production keys.
- ✓Azure API Management: Policy expressions, payload filtering, and rate limiting.
- ✓Azure AI Content Safety: Multi-modal risk scoring for enterprise LLM outputs.
Client & Engine Sandboxing
Browser Extensions & Client Runtime Isolation
Browser extensions hold privileged access to user browsing contexts and credentials. We engineer Manifest V3 extensions and web engines with bulletproof sandboxing.
Manifest V3 Strict Adherence
Eliminating remote code execution vulnerabilities by banning arbitrary eval() and remote scripts. All logic is bundle-verified and signed.
declarativeNetRequest Rules
Intercepting and modifying network requests at the browser engine level without exposing unencrypted client request bodies to content scripts.
Offscreen Sandbox Documents
Complex parsing and DOM operations run in isolated offscreen contexts with zero access to extension storage APIs or user cookies.
