SecureFlow: GitHub-native secret detection

Secrets were only caught after merge. I designed SecureFlow, a GitHub plugin that catches them inside the pull request, explains them, and guides the fix without leaving GitHub.

00The 30-second version
Problem
Secrets were only caught after merge. One AWS key stayed live in production for 60+ hours, and developers saw 80% of alerts as noise.
My role
Product Designer, end-to-end: research, the PR experience, and team dashboards.
Key decision
Catch secrets inline in the pull request, not in a separate dashboard, and block only what's critical.
Outcome
42% fewer unresolved secrets, 17% faster PR reviews, and 50% fewer security-related rollbacks.
01Strategy: where we went and why

Context

A developer opened a pull request on a Friday afternoon with an AWS key buried in the diff. The scanner didn't flag it until Monday, after the key had been live in production for 60+ hours. Cleanup took a full sprint: key rotation, audit review, incident report, compliance paperwork.

"By the time security tools tell me something is wrong, it is already a fire drill."
Developer, research interview

My role

I owned the work from research to shipped product. The big calls were mine: inline remediation over external dashboards, coaching over punitive alerts, and a 2-minute PR resolution threshold. Engineering preferred a standalone dashboard; research and side-by-side prototypes won the case for inline.

Constraints

Workflow

5 of 6 developers said they'd ignore any tool that pulled them out of the PR.

Stakeholder tension

Security wanted to block every merge until secrets were fixed. Developers needed to keep shipping.

Trust

False positives had already burned trust. Anything noisy would be ignored.

North star

"Zero context switching, zero external tools, zero workflow interruption."

Every decision was tested against this: security that lives where code is already reviewed.

Goals

Business

Prevent leaks before merge, cut remediation effort, and win adoption by removing friction.

Developers

Accurate, real-time detection in the PR and fixes without leaving GitHub.

Team leads

See patterns, risky habits and bottlenecks, and coach without micromanaging.

Why It Matters Visualization

Who it's for & jobs to be done

Developers

"When I create a pull request, I want real-time, high-accuracy secret detection inside GitHub so I can fix issues quickly."

Team leads

"When security issues repeat, I want visibility into patterns so I can coach my team and maintain compliance."

Jobs To Be Done Visualization

Research & insights

With PM support, I interviewed 6 developers and 3 team leads and shadowed their work across 2 sprint cycles over 2 weeks.

"I stopped looking at security alerts because 80% are noise."
Senior developer, user interview

Developers dropped tools that broke their flow, stopped trusting noisy alerts, and paid for every post-merge fix with a context switch.

The problem was timing, not intent. Developers weren't ignoring security. They had no signal until the code was already merged.

Primary Research Visualization

Opportunity

Competitors scanned after merge, lived in external dashboards, and were noisy. None gave developers speed and accuracy and leads visibility into recurring risks.

Gaps, each of which became a feature

  • No real-time feedback during PR review
  • High false-positive noise
  • Disconnected workflows requiring context switching
  • Lack of trend visibility for leads

Build where developers already work, not alongside it.

Market Opportunity Visualization

Decisions & tradeoffs

DecisionOptions consideredWhat we chose & why
Where detection lives Standalone dashboard (engineering's preference, simpler to build and maintain) Inline in GitHub pull requests
Developers said they'd ignore tools outside the PR. I prototyped both with the tech lead. Tested with developers, inline resolved issues 4x faster. We took on the harder build.
How strict to be Block every merge until all secrets are resolved
Warn only
Tiered severity model
Critical secrets block merge. Medium-risk ones warn and allow merge with acknowledgement. Low-risk patterns are informational.
How escalation feels Punitive alerts to leads Coaching-based escalation
Unresolved issues reach leads with context and teachable patterns, so they mentor instead of police.
Dismissing false positives Mandatory written justification (v1) One-click dismiss plus optional note
In v1, developers ignored alerts rather than justify them. A weekly digest now lets leads review dismissals in batch. Compliance rose from 20% to 42%.
02Solution: what the decisions produced

Solution

Developers stay in GitHub, leads get a dashboard of patterns and risks, and the organization gets automatic audit trails.

Before
  • Secrets caught after merge, sometimes 60+ hours later
  • Findings lived in external tools and dashboards
  • 80% of alerts felt like noise
  • One leak could cost a full sprint to clean up
After
  • Diff scanned the moment a PR opens
  • Inline annotations next to the risky lines
  • Tiered severity: only critical secrets block merge
  • Guided fixes in under 2 minutes, without leaving GitHub

Installation

Teams install it from GitHub Marketplace. The listing leads with the GitHub-native workflow, because leaving it was the top reason developers abandoned past tools.

PR check flow

Inline detection

SecureFlow scans the diff the moment a PR opens. A clean diff gets a green check and "safe to merge"; otherwise, annotations appear next to the risky lines. Developers can Remove, Ignore, Mark as False Positive, or Request Explanation.

Guided remediation

Each finding comes with a short explanation and guided next steps. Most take seconds, keeping PR resolution under the 2-minute threshold.

Issue creation

High-risk secrets automatically become GitHub issues with fix instructions, so they're tracked instead of lost in PR comments.

Team lead tools

Dashboard

A focused dashboard shows active risks, recurring patterns, high-risk contributors, resolution trends and audit trails. Security becomes a team habit leads can measure.

Escalation & coaching

Issues unresolved past a threshold go to the team lead with why it happened and the pattern behind it, so they can coach rather than punish.

Reflections

What didn't work

My first dismissal flow asked for a written justification on every "Mark as False Positive." Within a week, developers were ignoring alerts instead, so I cut it to one click with an optional note.

What I'd carry forward

  1. Respect the speed of the workflow

    Security tools only work when they keep pace with how developers ship.

  2. Inform, don't obstruct

    Leave developers in control. Block only what's truly critical.

  3. Habits scale, enforcement doesn't

    Lasting security comes from team habits, not policing.
