Common Challenges

Do any of these challenges sound familiar?

Uncertainty About Hidden Undisclosed Vulnerabilities

Your organization regularly scans for known vulnerabilities and applies patches — but there is no reliable way to verify whether undisclosed vulnerabilities are lurking in externally facing servers, core systems, or proprietary software products.

AI-Powered Attacks Are Outpacing Traditional Defenses

Frontier AI is fundamentally changing the threat landscape. As automated vulnerability discovery, analysis, and validation accelerate, cyberattacks move faster than ever — making it increasingly difficult for conventional approaches to get ahead of exploits before they happen.

No Strategy to Bridge the “Gap Period” Before Patches

Even when a vulnerability is identified, time is needed before a fix is released and deployed. Without an interim mitigation strategy, organizations remain exposed during this critical window of risk.

Service Overview

These challenges are exactly what Proactive AI Vulnerability Assessment is designed to address.

Proactive AI Vulnerability Assessment combines state-of-the-art large AI models (frontier AI) with a proprietary testing harness developed exclusively by NRI Secure. This powerful combination enables the detection of undisclosed vulnerabilities hidden in externally facing servers, core enterprise systems, and software products — before they can be exploited. From initial scoping through to the delivery of countermeasures, we provide comprehensive, proactive vulnerability management in a single integrated service.

How the Service Works

NRI Secure experts guide you through every step — from scoping to the delivery of countermeasures.

STEP

1

Assessment Scoping

NRI Secure specialists analyze source code and open-source software (OSS) SBOM data associated with the target systems or products to precisely define the assessment scope. Coverage includes externally facing servers, core enterprise systems, and software products (including firmware and embedded software).
STEP

2

Undisclosed Vulnerability Detection: Frontier AI × Proprietary Harness

Frontier AI models are combined with NRI Secure's proprietary testing harness to verify the presence of high-risk undisclosed vulnerabilities. The harness provides a fully integrated execution environment capable of running, testing, and evaluating system and AI behavior in a reproducible manner.
STEP

3

Delivery of Countermeasures Including Custom Signatures

For each detected undisclosed vulnerability, countermeasures are delivered to bridge the gap period before an official fix is available. These include custom intrusion prevention system (IPS) and web application firewall (WAF) signatures developed exclusively by NRI Secure. A comprehensive report is provided, covering vulnerability details, potential attack vectors, and operational guidance to minimize risk until the patch is applied.

Why Organizations Trust NRI Secure

1

Proven Vulnerability Detection Capability, Validated by Reproduction Testing

We have reproduced and validated representative vulnerabilities reported to have been discovered by Mythos — using publicly available frontier AI models combined with our proprietary harness. This confirms detection capability on par with Mythos, made possible exclusively through our independently developed harness.

2

Custom Signature Delivery and Actionable Countermeasures

For each undisclosed vulnerability detected, we provide custom IPS and WAF signatures along with a comprehensive countermeasure report — designed to bridge the gap before an official patch is released. This enables swift, informed action to reduce exposure while awaiting an official fix.

Deep Expertise in AI Security

NRI Secure has built extensive knowledge in AI security through a range of initiatives — including contributing to guidelines developed by Japan's AI Safety Institute (IPA) and authoring publications on AI security. This expertise forms the foundation of our service.

Frequently Asked Questions

Q How does this service differ from conventional vulnerability assessments?: A
Conventional assessments primarily focus on verifying the presence of known vulnerabilities — those already publicly disclosed (e.g., published CVEs). This service is fundamentally different: it combines frontier AI with a proprietary testing harness to actively verify the presence of undisclosed vulnerabilities that have not yet been made public.
Q What information do we need to provide for the assessment?: A
NRI Secure specialists will define the assessment scope based on source code and OSS SBOM data for the target system or product. Please contact us to discuss the specific information you are able to share.
Q What if an immediate fix is not possible after a vulnerability is discovered?: A We deliver custom IPS and WAF signatures, along with a comprehensive report covering vulnerability details, potential attack paths, mitigation measures, and operational guidance — all designed to reduce risk during the gap period before an official patch is released and deployed.
Q Can the service cover our in-house software products, including firmware and embedded software?: A
Yes. In addition to externally facing servers and core enterprise systems, the service covers software products including firmware and embedded software.
