The risk is real

Most startups are one mistake away from a breach

You're moving fast. Security usually isn't the priority — until it is. Here's what we see constantly:

API keys sitting in public repos

One committed secret can expose your database, payment processor, or cloud account — and bots are scanning for it 24/7.

No two-factor authentication

A single stolen password gives an attacker full access to your admin panel, customer data, and billing.

Cloud storage left wide open

Misconfigured S3 buckets and storage buckets are still one of the most common causes of data leaks — and they're trivially easy to exploit.

Outdated dependencies with known holes

Most applications run libraries with public CVEs that haven't been patched. You're vulnerable to attacks that have been documented for months.

A breach doesn't just cost money — it kills trust, tanks signups, and can end companies. We've seen it happen.

What you get

A complete security picture in 48 hours flat

No 80-page PDFs full of acronyms. Just a clear look at your vulnerabilities and a prioritized list of what to fix — starting today.

Full Vulnerability Scan

We scan your infrastructure, codebase, cloud config, and third-party integrations for known and unknown weaknesses.

Critical Risk Identification

We rank every finding by actual business risk — not theoretical severity. You'll know exactly what could hurt you most right now.

Code-Level Fix Plan

Every issue comes with a specific fix — including exact code snippets where possible. No vague recommendations, no guesswork.

Your report includes

  • Vulnerability report (10–15 pages)
    Structured, readable, shareable with your team or board
  • Severity ranking: Critical / High / Medium / Low
    Every finding rated and sorted by real-world business impact
  • Reproduction steps for every vulnerability
    Detailed enough that your developers can verify and understand each issue
  • Fix recommendations — code-level where possible
    Actual patches, config changes, and library upgrades — not just "fix your auth"

We cover

  • Authentication & session management
  • API security & exposed endpoints
  • Cloud configuration (AWS / GCP / Azure)
  • Secrets & credentials exposure
  • Third-party dependencies & supply chain
  • Data storage & encryption practices
  • Access control & privilege escalation
  • OWASP Top 10 vulnerabilities

Sample findings

This is what a real finding looks like

Every item in your report follows this format — severity labeled, reproducible, and immediately actionable.

Critical

JWT Secret Hard-Coded in Source Code

The application's JWT signing secret (JWT_SECRET=mysupersecret123) is hard-coded in src/auth/middleware.js:14 and committed to the public repository. An attacker can use this to forge valid authentication tokens for any user — including admins.

Reproduction

1. Clone repo from GitHub
2. Run node forge-token.js --user=admin
3. Use token in Authorization header → full admin access granted

Fix Recommendation

1. Rotate the secret immediately
2. Move to process.env.JWT_SECRET
3. Add .env to .gitignore
4. Audit git history & revoke exposed tokens

High

S3 Bucket Publicly Readable — User Data Exposed

The S3 bucket prod-user-uploads-v2 has public read ACL enabled. It contains 4,200+ user-uploaded files including documents with PII. Any unauthenticated request to the bucket URL returns a full directory listing.

Reproduction

1. curl https://prod-user-uploads-v2.s3.amazonaws.com/
2. Returns XML with 4,217 object keys
3. Any file directly downloadable via URL

Fix Recommendation

1. Set bucket ACL to private in AWS console
2. Enable Block Public Access at account level
3. Use pre-signed URLs with 15-min expiry for file access

Medium

No Rate Limiting on Password Reset Endpoint

The POST /api/auth/reset-password endpoint accepts unlimited requests per IP. An attacker can enumerate valid email addresses and spam resets, degrading user experience and leaking account existence.

Fix Recommendation

Add express-rate-limit: 5 requests/15 min per IP. Return identical response for existing & non-existing emails to prevent enumeration.

Your full report will contain every finding in this format — ranked, reproducible, and ready to hand to a developer.

Real findings

What we've found for clients like you

These are representative findings from recent audits. Every one of them was unknown to the founder before we started.

Critical

Exposed API keys in production repository

A SaaS startup's Stripe live API key, database connection string, and AWS credentials were all committed to a public GitHub repo. The repo had been public for 6 months.

B2B SaaS · Series Seed · 3 engineers

Resolved within 4 hours of report delivery

High

Authentication bypass in admin dashboard

A fintech app's admin panel was protected by a frontend redirect — but the underlying API endpoints had no server-side auth checks. Any unauthenticated user could access all customer financial data directly.

Fintech · Pre-seed · 2 founders

Fixed before next investor demo

High

User data readable by any authenticated account

An e-commerce platform's order history API returned results based on a sequential integer ID in the URL with no ownership check. Any logged-in user could enumerate and read every other customer's orders.

Questions we get asked

Do I need a technical background to understand the report? +

Not at all. Every finding is written in plain English with context about why it matters to your business and exactly what to do to fix it. We specifically avoid security jargon.

What access do you need? +

It varies by scope, but typically read-only access to your cloud console, code repositories, and a staging environment. We sign a full NDA before any access is shared, and you retain full control throughout.

Is 48 hours really the turnaround? +

Yes. The clock starts once you've shared access. We guarantee the full report and walkthrough call are delivered within 48 business hours — or your money back.

What if my team doesn't know how to fix something? +

The Growth plan includes 30 days of follow-up support. Ask us anything about implementing the fixes. We also offer optional implementation sprints if you'd prefer us to handle it directly.
