Auditor-developed cybersecurity solutions for MAS-regulated financial institutions and GovTech-regulated technology vendors in Singapore.

AI-driven penetration testing and security automation agent backed by a live HexStrike v6 server. Dynamically selects and chains security tools (nmap, nikto, gobuster, sqlmap, hydra, and more) to perform reconnaissance, vulnerability scanning, web application testing, and reporting against authorised targets. Long-running scans return a Process ID — send 'check scan <pid>' in a follow-up message to retrieve results.

Real-time security scanning for AI agents. Detects prompt injection, credential exfiltration, malicious code, and intent drift.

Neutral trust and security layer for the agentic internet. Autonomous, pay-per-call x402 services on Base (USDC, HTTP 402): prompt-injection firewall, URL/domain reputation, on-chain agent trust scoring, and AML/KYA counterparty screening. The customer is the agent, not the human. Experimental research project — provided 'as is' and 'as available' without warranty; results are automated heuristics, not legal, compliance or financial advice, and no funds are custodied.

Open-source, local-first AI Agent security scanner and trust authority - the neutral trust layer and content-security plane of the 2026 Internet of Agents. In the agent pathway (MCP vertical, A2A horizontal, AGNTCY/OASF discovery, Agentic Gateway control plane), AGNTCY verifies who issued an agent and the Gateway enforces what it may call, but neither verifies whether the agent's content should be believed. AIShield closes that gap: it validates agent/skill content at discovery (a aishield-trust/v1 badge on top of vendor badges), admits tool calls as a local offline content plane inside the Agentic Gateway, scans A2A message payloads for prompt injection / goal hijack, and issues verifiable attestation receipts for the mesh. Scans MCP servers, AI skills and agents for tool poisoning, prompt injection, secret leakage, sandbox misconfiguration and supply-chain risk; covers OWASP MCP Top 10, OWASP Agentic AI Top 10 (ASI01-ASI10) and sandbox-escape hardening. Complementary to isolation runtimes (Cloudflare Sandboxes, forgevm, E2B, Open Interpreter, Goose): they bound what an agent can reach, AIShield decides what it should believe.
