Immersive One launches Agentic Harness to verify autonomous AI safety and token spend

Agentic Harness replaces blind trust with ground-truth evidence, allowing enterprises to stress-test AI agents against live adversarial attacks, fix AI-native code vulnerabilities, and lock down AI budgets before reaching production.

BRISTOL, UK and BOSTON — July 29, 2026 — Immersive today announced the launch of Agentic Harness, the industry’s first operational proving ground in the cyber resilience space built to guarantee autonomous AI agents are safe, efficient, and cost-controlled before they ever touch production environments.

Enterprise AI adoption is accelerating at a breakneck pace, but governance is failing to keep up. Recent market data shows that while 37% of enterprises have deployed or tested autonomous AI agents, a staggering 3% actually have agent-specific security controls in place. Without rigorous validation, enterprises face a broad risk surface: unconstrained API usage and token burn capable of wiping out annual AI budgets in a single quarter, hallucinated outcomes masquerading as successful tasks, and unvetted AI agents operating within serious security gaps.

"Token economics and insecure agents are the top two concerns every leader brings up about using autonomous agents," said Aniket Menon, Chief Product Officer at Immersive. "You cannot trust AI agents as a control in production based solely on what they claim to do. Agentic Harness enables you to assess security, token efficiency, and benchmark model behavior to make sure you have verifiable proof of your AI agent's effectiveness."

Unlock the True Value of Agentic AI with Evidence

Agentic Harness solves the primary blocker preventing organizations from safely scaling AI: the inability to prove ROI, safety, and operational control prior to deployment. It gives decision-makers across the business the definitive proof they need to scale with speed:

• For CIOs, CISOs, and CFOs: Walk into board and budget meetings with verified execution trails and predictable token spend rather than unbacked financial projections. Meet strict regulatory mandates, including the EU AI Act’s August 2026 requirements, NIST AI RMF, and ISO 42001, with immutable compliance evidence.
• For Engineering and AppSec Leaders: Stop AI-generated vulnerabilities before code ships. Ensure engineering teams stay sharp by actively auditing AI-authored pull requests rather than deferring blindly to automated output.
• For Red Teams and Cyber Leaders: Eliminate subjective assessments. Validate exactly what offensive AI agents can breach using flag-capture proof instead of hallucinated reporting. Build effective agents for SOC and vulnerability management use cases. 

Core Capabilities: Test, Defend, and Control at AI Speed

The Agentic Harness provides a zero-risk sandbox powered by three core capabilities:

• Agent Tuning: Test, compare, and optimize your agents using frontier and open-source AI models in a safe sandbox. Get a complete audit trail of token spend, latency, and guardrails before going live.
• Offensive AI Ranges: Pressure-test red-team AI agents in isolated targets. Capture undeniable flag-capture proof of actual breach capabilities mapped directly to MITRE ATT&CK techniques.
• Developer AI Ranges: Catch AI-native security flaws in live pull requests. Place developers alongside AI coding agents to triage OWASP-mapped backlogs with ground-truth verdicts on what was caught or missed.

Availability

Immersive One’s Agentic Harness is now available to Immersive One Advanced customers. To see how Agentic Harness provides verified proof of agent safety, cost control, and execution fidelity, book a demo.
