Prepared by Acme Security · Powered by ZeriFlow
A security layer for fast-moving teams
Scan what you shipped, understand the risk, and fix the gaps your AI stack can miss.
Connect your AI-built app
Enter a public URL or connect your repository. ZeriFlow maps the security surface around what you shipped.
Run website and code checks
TLS, headers, cookies, DNS, email, privacy, source code, dependencies, and CI/CD risks are checked in one workflow.
Patch what AI missed
Get prioritized issues with clear fixes, then ship patches before users or attackers find the weak spots.
A URL scanner can't find secrets in your code. We can.
Connect your GitHub repo or upload a ZIP. ZeriFlow finds hardcoded API keys, CVEs in your dependencies, and insecure patterns before they reach production.
- Detect hardcoded API keys, tokens, and secrets
- Find vulnerable dependencies before they're exploited
- Audit authentication patterns and session handling
- Identify insecure API endpoints and data exposure
- Get architecture-level security recommendations
Included in Pro plan · $9.99/mo

“I built my SaaS in a week with Cursor and completely forgot about security. ZeriFlow caught 12 critical issues in my headers alone. Fixed them all in an hour.”
Sarah Chen
Indie Hacker
“We needed something between 'free and useless' and '$15K/year enterprise tools'. ZeriFlow is exactly that. The advanced scan found a hardcoded Stripe key our code review missed.”
Marcus Rodriguez
CTO, NovaPay
“My clients love getting a security report with their project delivery. ZeriFlow makes me look like I have a security team. I don't. It's just ZeriFlow.”
Emma Larsson
Freelance Developer
“The speed is what got me. 60 seconds for 80+ checks. I use it as a first-pass before our enterprise tools. Saves the team hours every sprint.”
James Okafor
DevSecOps, CloudBase
“We scan every client site before delivery now. It's become part of our QA process. The PDF export alone is worth the Pro plan.”
Léa Dubois
Co-founder, PixelAgency
“I was mass-producing Next.js apps with AI tools and shipping them without a second thought. ZeriFlow showed me how exposed they were. Now it's in my deployment checklist.”
Ryan Park
Full-Stack Developer
“Finally a scanner that doesn't overwhelm my non-technical clients. The score out of 100 is perfect — they instantly understand where they stand.”
Aisha Patel
Security Consultant
“Unlimited plan, lifetime deal. No brainer. We scan 50+ sites a month for our clients. ZeriFlow paid for itself in the first week.”
Tom Eriksen
Agency Owner, BuildFast
“We added ZeriFlow to our pipeline and caught an exposed `.env` file accessible at a public route on the first PR. Literally paid for itself in one scan.”
Alex Kim
DevOps Lead
“My AI agents commit code 50 times a day. ZeriFlow is the only thing standing between them and production disasters. Essential.”
Jordan Lee
AI Developer
“Setup took 2 minutes. Now every PR gets a security check. No more 'we'll add security later' — it just happens.”

* Subject to fair use policy to maintain service quality for all users.
Absolutely. ZeriFlow only performs non-intrusive, read-only checks — similar to what a regular browser does when visiting your site. We never attempt exploitation, injection, or any form of active testing. Your website remains completely unaffected.
Each of the 80+ checks is weighted based on severity and industry standards (OWASP, CIS Benchmarks). Critical issues like missing HTTPS or exposed admin panels weigh more than minor best-practice recommendations. The final score is a weighted average out of 100.
Quick Scan analyzes your website's publicly accessible surface — headers, TLS, cookies, DNS, and more. Advanced Scan goes deeper: it connects to your GitHub repo or analyzes a ZIP of your source code to find hardcoded secrets, vulnerable dependencies, insecure API patterns, and architectural risks that URL scanning can't detect.
No. Quick Scan works on any publicly accessible URL with no verification required. For Advanced Scan, you authenticate via GitHub OAuth or upload your code directly.
Yes, all plans are month-to-month with no commitment. Cancel anytime from your dashboard. If you're on the Lifetime plan, it's a one-time payment — no subscription to cancel.
Yes. Scan results are encrypted at rest and in transit. We don't store your source code after analysis — it's processed and discarded. We're fully GDPR compliant and don't sell or share your data. See our Privacy Policy for details.
You connect your GitHub account via OAuth and select the repository to scan. ZeriFlow clones the repo in a secure, isolated environment, runs static analysis for secrets, vulnerabilities, and insecure patterns, then generates a report. Your code is deleted immediately after analysis.
Yes, we offer a 14-day money-back guarantee on all paid plans. If you're not satisfied, contact us and we'll process a full refund, no questions asked.
Those tools are great starting points. ZeriFlow is broader because it checks TLS, headers, cookies, DNS, email security (SPF/DKIM/DMARC), content security, privacy, and more in one workflow. It also offers monitoring where enabled, CI/CD integration on supported plans, supported code-security workflows, and API access on supported plans.
Yes. The Business and Unlimited plans support multiple domains, making it easy to monitor all your clients' or team's sites from one dashboard. The white-label PDF feature lets you generate branded security reports under your own company name — no ZeriFlow mention anywhere. Agencies use this to deliver professional security audits to clients at scale.

What Is ZeriFlow?
ZeriFlow is security infrastructure for AI-built software, built for developers, agencies, and small teams shipping fast with AI coding tools. Enter any URL and ZeriFlow runs 80+ non-intrusive security checks across 12 categories quickly. You get a clear security score out of 100, a prioritized list of vulnerabilities, and actionable recommendations to fix each issue.
What Does ZeriFlow Check?
Every scan covers the security areas that matter most: TLS/HTTPS configuration (certificate validity, protocol versions, cipher suites), HTTP security headers (Content-Security-Policy, HSTS, X-Frame-Options, and more), cookie security (Secure, HttpOnly, SameSite flags), information disclosure (server fingerprinting, exposed files, directory listings), DNS and network security (DNSSEC, CAA records), email authentication (SPF, DKIM, DMARC), content security (mixed content, subresource integrity), privacy compliance, performance, and accessibility.
For deeper analysis, ZeriFlow's advanced scan combines deterministic URL security testing with source code auditing. Connect your GitHub repository or upload a ZIP file, and ZeriFlow analyzes your actual codebase for hardcoded secrets, vulnerable dependencies, insecure API patterns, authentication flaws, and architectural risks that AI-generated code can miss.
Why Choose ZeriFlow?
Unlike enterprise-grade vulnerability scanners that cost thousands per year, ZeriFlow gives fast-moving teams a practical security layer for websites, AI-powered CI/CD and GitHub security workflows where implemented, and monitoring. Its AI-assisted guidance is designed to add context and reduce noisy findings where possible. Every scan is completely non-intrusive and GDPR-compliant.

You can also review public, aggregate website security statistics to see common scan trends and frequent configuration issues.
