How to Create Merge-Ready AI Code Fixes That Engineers Trust

September 30, 2026

What an AI autofix PR needs before a developer merges it untouched: a finding worth fixing, a minimal diff, proof, the right reviewer and green CI.

Exploitability Is Only Half the Triage Decision

Shantanu Kulkarni

Exploitability is only half of vulnerability triage. See how Vault grounds impact scoring in your organization’s business context, so the findings that matter most move first.

Automating the Last Mile: Escalating Fixes Before They Breach SLA

A fix PR that nobody reviews is a vulnerability that nobody closed. We now follow fix PRs all the way to the merge: resolving who owns the code, checking whether they have capacity to review it, and escalating on the schedule your own runbooks define.

Dependency Cooldowns: Catching Supply-Chain Attacks Before a CVE Exists

Catching Supply-Chain Attacks Before a CVE Exists: Pins, Cooldowns, and Threat Investigations

A supply-chain worm lives and dies before a CVE is ever filed. We built a five-part system for that gap: unpinned-dependency detection with autofix PRs, dependency cooldowns enforced by us and by your own tooling, a PR gate for too-fresh versions, and AI threat investigations that sweep every repo and CI pipeline to answer "are we affected, and did it run?" in hours.

Action Items, Not Alerts: Resolving Findings Without Growing the Team

Action Items, Not Alerts: Resolving Findings Without Growing the Team

A security program is a headcount problem wearing a tooling costume. The scanner is cheap; the humans who route, triage, and chase every finding are not. So the real question for any AppSec platform…

Exploit Validation: Proof, Not Guesses

A scanner finding is a guess. Nullify proves it: triaging down to what is real and reachable, then generating and running a reproducible exploit against a live target, with the evidence and a reproduction you can re-run yourself.

An Inventory You Can Query Beats a Vulnerability List You Have to Grep

An Inventory You Can Query Beats a Vulnerability List You Have to Grep

Nullify's whole premise is that security work — finding, triaging, program-managing, and fixing exposure — can run end-to-end, cheaply, on AI that stays controlled and measurable, so a team's output…

Stop Paying to Triage Vulnerabilities That Were Never Reachable

Stop Paying to Triage Vulnerabilities That Were Never Reachable

Every high-CVSS finding a scanner hands you demands the same thing: someone's attention. If you've pointed an AI agent at the queue, it demands the same token spend too. And most of that attention…

Outcomes, Not Headcount: The Context Layer Behind Controlled Security Automation

Outcomes, Not Headcount: The Context Layer Behind Controlled Security Automation

Attackers have already figured out that capability no longer scales with headcount. The tooling to run the kind of simultaneous, multi-target campaign that used to take a whole crew is now…

We are asked all the time about new model releases and security code review features from the big AI labs. This blog explains how Nullify is better together with these advancements to maximize the value they create for our customers.
