Founder and Director, Final Frontier Ventures Chief AI Officer, ES2 Solutions
Security and AI, explained plainly.
I build AI security products. I founded Final Frontier Ventures, where I architected and created AttackSight and published the open Safer Agent Memory Standard. I'm also Chief AI Officer at ES2 Solutions, and I bring close to two decades of cybersecurity, AI, and enterprise delivery experience to both.
Final Frontier Ventures is the privately held venture platform I founded in Sri Lanka. It builds and holds technology products for the long term.
Attack surface
AttackSight
Connected attack surface intelligence
I architected and created AttackSight, an FFV product. It connects what an organisation exposes, from systems and people to brand and leaked data, so teams can see where an exposure leads and what to fix first.
AI examines findings the way an experienced tester would, and the full picture resolves into one risk score from 0 to 100.
Agent memory can turn a one-off prompt injection into a standing instruction. SAMS treats memory as an attack surface, with scoped memory, taint tracking, tenant isolation, and a human review gate.
It includes the standard, a Python library, a conformance suite, a Claude Code plugin, and an MCP server. Version 0.2 adds a Postgres backend with row-level security. I co-authored it with Claude, and it's an open-source alpha release.
Penetration testing, attack surface management, cloud security, and CBSL compliance, with ISO 27001, ISO 27701, ISO 42001, PDPA, and GDPR expertise.
AI
Enterprise AI platforms and agentic systems, from MLOps and RAG to virtual agents.
AI security
Securing agents themselves, including prompt injection, agent memory, and governance for AI-assisted software development.
My work has served enterprise clients across Sri Lanka and other countries. I'm also a certified PMP and PMI-ACP, and I've led large transformation programmes using SAFe and Scrum.
