Find auth bugs before your users do.
VolPen watches your app traffic while you browse, flags risky endpoints, safely proves exploitable issues, and gives you paste-ready fixes for Cursor, Copilot, or your IDE.
VOLPEN
Local security assistant
Ready to scan. Start capture to lock onto this tab and watch network traffic locally.
From scan to fix in one popup.
The demo is intentionally close to the real extension experience. Click through the steps to see how VolPen turns raw traffic into actionable security fixes without forcing you to leave your flow.
- Hit record and browse your app normally.
- Review findings with evidence and severity.
- Run consent-gated probes to confirm the bug.
- Copy a fix brief straight into your AI coder.
Built for builders who move too fast for traditional pentesting
Use VolPen as a pre-flight security check before sharing a staging link, shipping a feature, or handing work to a real pentester.
AI makes apps faster to ship — and easier to mis-secure
Vibe-coded apps often work beautifully in the happy path but miss boring checks like tenant scoping, cookie flags, and authorization edge cases.
Generic scanners miss your business logic
Most scanners are blind to who should access what. VolPen learns context from your actual session and observed routes.
Reports are not the outcome. Fixed code is.
Every important finding should end with a practical remediation prompt your builder can apply immediately.
Catch the bugs that actually block a launch
VolPen focuses on the issues most likely to hurt modern SaaS apps: broken auth, data leaks, API misconfigurations, and common OWASP mistakes.
Auth & tenant leaks
- Cross-tenant data leakage
- IDOR via sequential IDs
- Mass assignment bugs
- Broken authorization checks
API security mistakes
- Rate limiting gaps
- CORS misconfigurations
- Weak JWT handling
- Excessive data exposure
OWASP basics
- Reflected & DOM XSS
- SQL injection signals
- Missing CSRF tokens
- Bad cookie flags
- Sensitive data in URLs
- Open redirects
- Mixed content
Do not just flag it. Prove it.
Passive findings are useful, but confirmed behavior is better. VolPen can replay observed requests with targeted mutations and compare the expected response with reality. Write-capable probes stay locked behind explicit consent.
Local scanning without the lag
Security checks are useful only if developers actually leave them on. VolPen is designed to run quietly while you test your product flow.
Fast enough to leave running
Pre-filters skip harmless payloads before heavy rules run, so VolPen can watch real browsing without slowing your app down.
Understands routes as you browse
Observed endpoints are indexed and grouped so active probes can target admin, auth, and tenant-sensitive paths first.
Known signatures built in
Common Nuclei-style checks are bundled into the extension, giving you useful coverage without an external scanner.
Learns identity context
JWTs, cookies, user IDs, and tenant hints are profiled locally so VolPen can spot authorization flaws that generic scanners miss.
Optional AI review that ends in a patch
Bring your own Groq key. VolPen redacts secrets, validates findings, and creates a framework-aware remediation brief you can paste into your coding assistant. AI is off by default.
What the AI layer does
Skip the PDF. Give your builder the fix.
Every finding includes rule ID, severity, evidence, reproduction context, and optional AI remediation. Export it or paste it directly into your coding workflow.
Example fix brief
Finding: RLS-002 / IDOR
Endpoint: GET /api/events/:id
Evidence: Adjacent numeric IDs return 200 instead of 403/404.
Fix: Enforce tenant ownership in the data query and never trust route params alone.
// Express — enforce tenant scoping
router.get('/events/:id', requireAuth, async (req, res) => {
const ev = await db.event.findFirst({
where: {
id: req.params.id,
tenantId: req.user.tenantId,
},
});
if (!ev) return res.sendStatus(404);
res.json(ev);
});Security tooling should not become the security risk
VolPen earns trust with clear defaults: local analysis, scoped capture, explicit consent, and optional AI.
Local-first by default
Detection runs inside the extension. Raw traffic, headers, bodies, and tokens are not uploaded to VolPen servers by default.
Strict MV3 posture
Built for Manifest V3 with a strict content security policy and no remote code execution.
Consent gates for active probes
Any replay or mutation that could change behavior requires explicit confirmation before it runs.
Pinned tab and domain scope
Scans are scoped to the tab and domain you start from to reduce accidental cross-site capture.
Answer the doubts before they block the install
Is this a replacement for a professional pentest?
No. VolPen is a developer pre-flight tool. It helps you catch obvious and business-logic issues earlier, before you pay for a formal review.
Can I use it on production?
Start on localhost or staging. Passive capture is low risk, but active replay should be used only where you have permission and understand the impact.
Does my app traffic leave my machine?
Not by default. The extension analyzes traffic locally. Optional AI review can send redacted finding summaries only after you choose to run it.
Who is this for?
Solo builders, AI-assisted teams, agencies, and developers who want a fast security check before sending a link to users, clients, or investors.
Run a security check before your next deploy.
Install VolPen, open your app, and start capture. In minutes you will know which findings need attention and what to fix first.
