Fighting AI with AI: Why Zero-Day Discovery Is Only Half the Battle

Written by Harsha Koushik | Wed, May 27, 2026 @ 11:55 AM

The three questions that change everything

Static vulnerability scanners answer what exists. Runtime intelligence answers what matters.

1. Reachability — is this actually accessible to an attacker?

A vulnerable library is only dangerous if it can be triggered through a real code path from an externally influenced input. Container images routinely include vulnerable packages that are never executed at runtime. Cloud misconfigurations create reachability paths that no code scanner sees — an overprivileged IAM role or unintended public endpoint changes the entire attack surface calculus. Wiz maps cloud-layer reachability continuously. Netenrich's runtime layer adds the behavioral dimension: what processes are actually running, what network connections are live, what credentials are being accessed right now.

2. Exploitability — is there a working exploit, and is it being used?

Exploitability exists on a spectrum: theoretical, proof-of-concept published, embedded in active threat actor toolkits, observed in live attacks against your industry. Threat intelligence identifies where on that spectrum each vulnerability sits. CodeMender validates whether your specific code configuration is vulnerable to known exploit patterns — not just whether the CVE version matches. Netenrich's SOC telemetry adds behavioral signals: reconnaissance patterns, exploit attempts, anomalous process behavior consistent with known attack chains.

3. Blast radius — if exploited, what does the attacker reach?

This is the question an attacker is actually thinking. Which service accounts or API keys are accessible from this component? Can an attacker pivot from a compromised application tier to database infrastructure or cloud management planes? Does the blast radius intersect regulated data triggering mandatory breach notification? Blast radius is where vulnerability management meets incident response — high blast radius findings need a 30-minute containment capability more than a 5-day patch SLA. Mandiant delivers the strategic guidance to help organizations create actionable response plans.

 

The closed loop: find, fix, and monitor in concert

Google AI Threat Defense operates as a continuous four-step framework:

  • Prepare: Harden your foundation, and operationalize your framework for machine-speed prioritization and response.
  • Scan and Prioritize: Conduct deep-dive analysis and AI-driven posture validation.
  • Remediate: Implement a workflow to autonomously verify and accelerate the patching of vulnerabilities.
  • Monitor Transition to continuous detection and rehearsed, active response playbooks.

Netenrich's role is the intelligence layer that enhances trust and makes this loop calibrated to your environment — not a generic enterprise template.

Runtime signal correlation

When CodeMender identifies a critical vulnerability, our platform immediately cross-references it against behavioral telemetry: has this service shown anomalous behavior in the last 30 days? Are there unexpected network connections to it? Has the process spawned child processes consistent with exploitation? The vulnerability finding and the runtime signal are evaluated together — not in separate queues weeks apart.

Prioritization tuned to your environment

A CVSS 8.0 in a PCI-scoped cardholder data environment is not the same risk as a CVSS 8.0 in a development sandbox. Generic scoring models are calibrated to average environments. Netenrich encodes your compliance obligations, crown jewel assets, and network architecture into the prioritization model — so the remediation queue CodeMender burns down is the right queue, not the loudest one.

Active exploitation monitoring while the backlog closes

Patches take time. Some vulnerabilities require architectural changes or vendor fixes. Zero-days are unknown until exploited. Google Security Operations — integrated into Netenrich's SOC operations — watches production for active exploitation while remediation is in progress:

  • Behavioral anomalies consistent with CVE exploitation: unusual process spawning, unexpected network pivots, privilege escalation sequences
  • Lateral movement signals: auth to unusual systems, data staging, IAM policy modifications consistent with attacker persistence

The monitor layer answers what the patch layer cannot: of the vulnerabilities we haven't fixed yet, which are being actively probed against us right now? That signal updates the remediation priority queue in real time.

 

Critically, monitoring feeds remediation — they are not separate workstreams. Active exploitation signals elevate specific vulnerabilities in the queue even if their CVSS score is moderate. Post-patch telemetry confirms whether a fix eliminated the attack vector or whether the adversary found an alternative path. Threat intelligence shapes what CodeMender scans for next. This is the feedback architecture that allows the system to adapt to adversary behavior as it evolves.

 

What this looks like: a Monday morning zero-day

A CVSS 9.1 RCE is disclosed. Proof-of-concept code is public within 24 hours. Threat intelligence confirms an APT group is actively scanning financial services environments.

  • Within the first few hoursWiz finds 200 instances of the affected library across your estate. Netenrich operations layer narrows to 12 of them and needs attention in production with behaviours observed.
  • Blast radius analysis reveals 3 of 12 sit in network segments with direct access to customer data stores — immediately P0. CodeMender validates that your specific code is exploitable, not just version-matched.
  • CodeMender generates sandbox-verified patches for the 3 P0 instances. Engineering reviews and approves. The remaining 9 are scheduled for the next deployment window with compensating controls applied immediately.
  • Google Security Operations monitors all 12 for exploitation patterns specific to this CVE. Any probe triggers an alert with full context — which instance, what the attacker is attempting — with a pre-built Netenrich playbook ready for containment in minutes.

 

A CVSS 9.1 that could have generated 200 patch tickets and weeks of engineering scramble is handled as 3 emergency deployments, 9 scheduled updates, and active monitoring covering the gap throughout.

 

The thesis

The Defender's Advantage in the AI era is not more people or more tools. It is a better signal, sharper prioritization, and a faster closed loop between detection and remediation. AI finds vulnerabilities at machine speed — but fixing all of them is not the goal, and never was. The goal is ensuring that the vulnerabilities being actively leveraged against you are the ones your remediation engine is burning down first, and that active exploitation of anything in the backlog is detected and contained before it becomes a breach.

That is the architecture Google AI Threat Defense and Netenrich are built to deliver — together.
