How Nullify AI works

The harness understands how your application works, so it finds the logic flaws that pattern scanners miss.

Campaigns

Close fixes across every team without sending a single reminder

A campaign owns the work until it is done, at scale. It reads ownership from Compass to find who, capacity from Jira to know when, and escalates in Slack when work stalls. It assigns, follows up and closes on merge with no human chasing.

WhoCompass — the codeowner of every affected path

WhenJira — sprint capacity, so work lands when teams can take it

WhySlack — escalation the moment an SLA is at risk

Business Logic Flaws

Find the bugs attackers would find first

Pattern scanners match signatures and cannot reason about intent. Nullify understands how your application works, so it catches the vulnerabilities that only come from logic: broken access control, privilege escalation, insecure workflows, IDOR and race conditions.

✓Reasons across endpoints, roles and data ownership

✓No rule to write, no signature to match

✓In-scope pentest findings backed by reproducible exploit evidence

Broken Access Control · IDOR

Triage

Stop wasting your mornings on false alarms

Nullify checks every finding against your risk model in Vault and removes the noise, so the queue your team sees is small, real and ranked.

hours/yr saved triaging false positives

80% of low-severity noise auto-suppressed before a human looks.

Validated Exploits

Your developers can run the exploit themselves

Nullify works out whether a finding can be exploited using runtime reachability, network exposure and cloud context, then proves it by stepping through the attack live, reasoning between each call. Every triage decision is backed by code.

Self-Healing Fixes

Get merge-ready fixes without chasing anyone

When a fix PR fails a check, Nullify looks into the failure, reads the build logs and pushes follow-up commits until every check passes and the pull request is ready to merge. No developer has to babysit it.

89%

merge-ready rate across our customers

Developers refactor a Nullify fix only ~1 in 10 times.

First upgrade broke a sync caller — jwt.verify now throws. Added error handling; pipeline green.

Reviewer Routing

Every fix lands with the person who can merge it

Every fix arrives as a clean pull request with the change explained inline. It is assigned using code ownership and current review capacity, so it reaches the engineer who can merge it fastest.

✓Assigned by ownership, balanced by review load

✓The reasoning travels with the suggested change

✓Accept in one click, or reply and Nullify revises

middleware/verify.js Conversation · 1

nullify bot suggested a change

The token verification can throw on a malformed JWT and crash the request. Wrapping it returns a clean 401 instead.

Suggested change

- const p = jwt.verify(token, key)

+ let p; try { p = jwt.verify(token, key) }

+ catch (e) { return res.status(401).end() }

Escalations

Spend your time on calls only a human can make

Most work closes on its own. When a fix needs a judgment call, such as accepting a risk, a breaking change or an SLA about to slip, Nullify escalates to the right person in Slack with full context and a one-click decision, then tracks it until it is resolved.

✓Escalates only what really needs a human

✓Full context attached: finding, blast radius and proposed fix

✓One click to approve, adjust scope, or accept the risk

Maximize your token budget

Spend your tokens on real bugs, not noise

AI only pays off when it works on the right things. The harness runs a mix of models and automatically routes work to cheaper ones when that is all a task needs, so your budget goes to the findings that matter most.

✓A mix of models, with automatic routing to cheaper ones

✓The most exploitable, widest-impact work goes first

✓Every token is tracked and every decision can be audited

✓Engineers spend time on judgment calls, not triage queues
