What is vibe coding and why does it need security scanning?

Vibe coding means using AI tools like Cursor, Bolt, v0, and Lovable to generate code quickly by describing what you want. While fast, AI-generated code often contains security vulnerabilities like XSS, SQL injection, exposed API keys, and missing authentication. OverMCP scans this code and fixes it automatically.

How does OverMCP scan my website?

Paste any live URL or GitHub repo link. OverMCP crawls your site, extracts all code (HTML, JS, CSS), follows source maps to find original source files, and runs 4 parallel AI analyses: security audit, SEO/AEO check, performance audit, and dependency CVE scan.

What is AEO (Answer Engine Optimization)?

AEO makes your website visible and recommendable by AI chatbots like ChatGPT, Claude, and Perplexity. OverMCP checks your AI bot permissions, generates llms.txt files, adds JSON-LD structured data, and optimizes your content for AI comprehension.

What payment methods are accepted?

OverMCP accepts crypto payments including Bitcoin, Ethereum, USDT, and many other cryptocurrencies. This keeps checkout accessible globally without requiring a credit card.

Can OverMCP automatically fix my code?

Yes. The $5 Fix tier creates a GitHub Pull Request with all security fixes applied. The $19 Deploy tier goes further — it deploys the fixed version directly to your hosting platform (Vercel, Netlify, Cloudflare Pages, or Railway) in one click.

SaaS Security Audit Cost: What Small Apps Pay in 2025

OverMCP Team

July 4, 2026

TL;DR: What Does a Security Audit Cost for a Small SaaS?

The cost of a security audit for a small SaaS typically ranges from $500 to $5,000 for automated scanning and $5,000 to $20,000 for a manual penetration test. Factors like app complexity, number of endpoints, and compliance requirements (SOC 2, HIPAA) drive the price. For indie devs on a budget, automated tools like OverMCP offer a cost-effective middle ground at a fraction of manual rates.

Breaking Down SaaS Security Audit Costs by Type

Security audits for SaaS apps fall into three main categories, each with a different price tag:

1. Automated Vulnerability Scanning ($500 – $5,000)

Tools scan your codebase, dependencies, and API endpoints for known vulnerabilities (CVEs), misconfigurations, and exposed secrets.

•Example: A simple Node.js/React app with 5 API endpoints might cost $500–$1,000/year for a subscription scanner.

•What you get: Continuous monitoring, weekly reports, alerts for new vulnerabilities.

•Pros: Cheap, fast, repeatable.

•Cons: Misses logic flaws, business logic bugs, and complex attack chains.

2. Manual Penetration Testing ($5,000 – $20,000+)

A human ethical hacker probes your app for vulnerabilities that automated tools miss.

•Example: A SaaS with user authentication, payment processing, and admin panels typically costs $10,000–$15,000 for a one-week test.

•What you get: Deep analysis of authentication flows, authorization bypass, business logic flaws, and a detailed report with remediation steps.

•Pros: Catches critical logic errors, OWASP Top 10 issues, zero-days.

•Cons: Expensive, one-time snapshot, slow turnaround (1–3 weeks).

3. Hybrid Approaches ($2,000 – $8,000)

Combine automated scanning with limited manual review. Many boutique security firms offer this tier.

•Example: Automated scan + 2 days of manual testing for $4,000.

•What you get: Broad coverage with deep dives into critical areas.

•Pros: Balanced cost and depth.

•Cons: Not as thorough as full pentest.

saas security audit cost: Real-World Examples

Example 1: Solo Dev with a CRUD App

•App: 10 API routes, Firebase auth, Postgres database, React frontend.

•Audit type: Automated scanner (e.g., OverMCP).

•Cost: $500–$1,000/year.

•Findings: 3 medium-severity issues (exposed API keys, missing rate limiting, outdated dependency).

Example 2: 3-Person Startup with Payment Processing

•App: Stripe integration, user roles, file upload, 50+ endpoints.

•Audit type: Hybrid pentest.

•Cost: $5,000–$8,000.

•Findings: IDOR in user profiles, XSS in file upload, weak JWT secret.

Example 3: Compliance-Ready SaaS (SOC 2)

•App: Enterprise features, SSO, audit logs, data encryption.

•Audit type: Full manual pentest + compliance audit.

•Cost: $15,000–$25,000.

•Findings: Several high-risk issues (broken access control, SQL injection, insecure direct object references).

Factors That Influence Cost

App Complexity: More endpoints, third-party integrations, and user roles increase scope.

Code Language & Framework: Python/Django vs. PHP/Laravel vs. Next.js—each has different attack surfaces.

Authentication & Authorization: Custom auth vs. OAuth vs. Firebase—custom auth is riskier and costs more.

Compliance Requirements: SOC 2, HIPAA, PCI-DSS add overhead and documentation review.

Auditor Experience: Top-tier firms charge $200–$400/hour; freelancers charge $50–$150/hour.

How to Reduce Your Security Audit Cost

•Fix low-hanging fruit first: Run a free linter (e.g., Semgrep, ESLint security plugin) to remove obvious issues before hiring a pentester.

•Use automated scanning regularly: Tools like OverMCP catch most common vulnerabilities (exposed secrets, misconfigurations) for a flat annual fee.

•Limit the scope: Audit only critical features (auth, payments, admin) instead of the whole app.

•Bundle with other services: Some firms offer discounts if you also do performance testing or compliance prep.

Why Automated Scanning Is the Best Value for Indie Devs

For solo makers and small teams, spending $10,000 on a pentest is often overkill. Automated scanning tools provide continuous protection at a fraction of the cost. For example, OverMCP (overmcp.com) scans your codebase for leaked secrets, vulnerable dependencies, and misconfigurations—starting at $500/year. It's designed for AI-built apps (vibe-coded with Cursor, Bolt.new, etc.) that often skip security.

When You Absolutely Need a Manual Pentest

•You handle sensitive user data (health records, financial info).

•A customer or investor demands a pentest report.

•You've already run automated scans and fixed all findings but want final assurance.

•Your app is complex (e.g., multi-tenant, real-time collaboration, file sharing).

Conclusion

The saas security audit cost for small apps is manageable if you choose the right approach. Start with automated scanning ($500–$1,000/year) to catch the obvious stuff, then upgrade to a hybrid or manual audit as your app grows and compliance demands increase. OverMCP offers a developer-friendly way to get started.

FAQ

How much does a security audit cost for a small SaaS app?

A small SaaS app can expect to pay $500–$5,000 for an automated scan or $5,000–$20,000 for a manual penetration test, depending on complexity and compliance needs.

Can I do a security audit myself for free?

Yes, you can use free tools like OWASP ZAP, Semgrep, or npm audit to find basic vulnerabilities. However, they lack the depth of paid services and won't catch business logic flaws.

Is a security audit worth it for a pre-revenue SaaS?

Not always. Focus on fixing obvious issues (hardcoded secrets, outdated dependencies) with free tools first. Once you have paying users or handle sensitive data, invest in a professional audit.
