Web Application Security Audit
Find the vulnerabilities in your web app, APIs, and cloud setup before attackers, customers, or auditors do. You get prioritized findings, clear fixes, and a report you can share with stakeholders.
Is Your Web Application Secure Enough for Real Customers?
Most web applications go live with security gaps nobody checked for. A feature works, so it ships, but working and secure are not the same thing.
A security audit is the right next step if:
You store customer data, payments, or personal information
An enterprise customer sent you a security questionnaire
You're preparing for SOC 2, ISO 27001, GDPR, or HIPAA readiness
You're raising funding and investors will run technical due diligence
Your app was built quickly, by freelancers, or with AI coding tools
You've never had an independent security review
You recently had a suspicious incident, breach attempt, or data leak
A web application security audit tells you where you're exposed, how serious each risk is, and what to fix first.
Common Vulnerabilities We Find in Web Applications
Vulnerability | What It Looks Like | Business Risk |
Broken access control | Users can view or change other users' data by changing an ID in a URL or API call | Data breach, regulatory penalties |
Weak authentication | No rate limiting on login, weak password rules, sessions that never expire | Account takeover |
Injection flaws | Unsanitized input reaching SQL queries, commands, or templates | Database theft, server compromise |
Exposed secrets | API keys, tokens, or credentials in frontend code or Git history | Stolen access to paid services and data |
Insecure APIs | Endpoints missing authorization checks or returning excess data | Silent data leakage |
Cross-site scripting (XSS) | User content rendered without escaping | Session hijacking, defaced pages |
Security misconfiguration | Debug mode in production, open CORS, missing security headers | Easier attacks, information disclosure |
Vulnerable dependencies | Outdated packages with known CVEs | Exploitable by automated attacks |
Public cloud storage | S3 buckets or storage containers readable by anyone | Mass exposure of files and documents |
Missing logging and monitoring | No alerts for failed logins, errors, or unusual access | Breaches go undetected for months |
What Our Security Audit Covers
Area | What We Assess |
Authentication | Login flows, password policies, MFA, session management, token handling, password reset |
Authorization | Role checks, object-level access control, privilege escalation paths, admin functions |
Input Handling | SQL/NoSQL injection, XSS, command injection, file upload validation |
APIs | Authorization per endpoint, rate limiting, data exposure, API keys, GraphQL and REST security |
Data Protection | Encryption in transit and at rest, sensitive data handling, PII exposure, backups |
Secrets Management | Hardcoded keys, environment variables, Git history, secret rotation |
Dependencies | Known vulnerabilities (CVEs), outdated frameworks, abandoned packages |
Configuration | Security headers, CORS, CSP, cookies, TLS, error messages, debug settings |
Cloud & Hosting | Storage permissions, IAM roles, network exposure, database access, environment separation |
Logging & Monitoring | Security event logging, alerting, audit trails, incident visibility |
Built on Recognized Security Standards
Our assessment methodology is aligned with widely used industry frameworks:
OWASP Top 10: the most critical web application security risks
OWASP API Security Top 10: security risks specific to APIs
OWASP ASVS: the Application Security Verification Standard, used for control-level checks
CWE: a standard classification for every weakness we report
CVSS: severity scoring, so findings are prioritized consistently
This gives you a report that security teams, auditors, and enterprise customers can recognize and trust.
Audit Approaches
Code-Level Security Review (White-Box)
We review your source code to find vulnerabilities at the root: access control logic, input handling, secrets, and dependencies.
Best for: finding root causes and getting exact fixes.
Running Application Assessment (Black-Box / Grey-Box)
With your written permission, we test the deployed application in a staging or agreed environment, the way a real attacker would.
Best for: confirming what is actually exploitable from the outside.
Combined Security Audit (Recommended)
Code review plus application testing. Findings from the code are confirmed against the running app, which cuts false positives and gives the most complete picture.
Best for: apps with paying customers, sensitive data, or compliance requirements.
Technologies We Audit
Frontend: React · Next.js · Vue · Angular · Svelte
Backend: Node.js · Python (Django, FastAPI, Flask) · PHP (Laravel) · Java (Spring) · .NET · Ruby on Rails · Go

How the Security Audit Works
1. Scoping Call
We learn about your application, users, data, and security concerns, then agree on the scope, testing approach, and environment.
2. NDA and Authorization
We sign an NDA and a written testing authorization before any access. No testing happens outside the agreed scope.
3. Assessment
Our engineers combine automated scanning with manual testing of authentication, authorization, business logic, APIs, and configuration. Automated tools alone miss the access-control flaws that cause most real breaches.
4. Validation
Every finding is manually verified to remove false positives. You only receive real, reproducible issues.
5. Report and Walkthrough
You receive a prioritized findings report and a walkthrough call with your team to explain the risks and plan the fixes.
6. Retest (Optional)
After you fix the issues, we verify each fix and issue an updated report showing the resolved status.
What You Receive
Executive summary: overall security posture and top risks for leadership and non-technical stakeholders
Findings report: every vulnerability with its CWE classification, CVSS-based severity, affected component, and evidence
Reproduction steps: clear steps so your developers can confirm each issue
Remediation guidance: specific fixes, with code-level recommendations where applicable
Prioritized roadmap: what to fix immediately, this month, and later
OWASP Top 10 coverage matrix: a mapping of what was tested against each OWASP category
Walkthrough call: a findings session with your engineering team
Typical Security Audit Scenarios
These examples show common situations, the kinds of issues that typically surface, and how teams use the results.
Scenario 1: SaaS Company Facing an Enterprise Security Questionnaire
Stack: Next.js + Node.js + PostgreSQL on AWS ·
Audit: Combined Security Audit
Situation: A growing B2B SaaS closes in on its first enterprise deal. The buyer's procurement team sends a 200-question security questionnaire and asks for evidence of a recent independent security assessment.
Common findings:
API endpoints that return other tenants' records when the organization ID is changed
No rate limiting on login, which allows credential-stuffing attacks
Missing security headers (CSP, HSTS) and overly permissive CORS
An S3 bucket for customer uploads with public list permissions
What happens next: The team fixes the critical tenant-isolation issue and the storage exposure first, then completes a retest. They share the executive summary and retest confirmation with the enterprise buyer as evidence of independent security review.
Scenario 2: E-Commerce Platform After a Suspicious Incident
Stack: Laravel + MySQL + Stripe ·
Audit: Combined Security Audit
Situation: An online store notices unusual orders and several customers reporting account access they didn't recognize. The team doesn't know whether it's a one-off or a deeper vulnerability.
Common findings:
Password reset tokens that never expire and can be reused
Order history accessible by changing the order number in the URL
An outdated framework version with a publicly known vulnerability
No logging of failed logins or admin actions, so the incident can't be traced
What happens next: The store patches account takeover paths immediately, upgrades vulnerable dependencies, and adds security event logging and alerts. Future suspicious activity becomes visible within minutes instead of weeks.
Scenario 3: Health-Tech Startup Preparing for Compliance Readiness
Stack: React + Python (FastAPI) + MongoDB on Google Cloud ·
Audit: Code-Level Security Review + Cloud Configuration
Situation:A startup handling patient appointment data is preparing for HIPAA and SOC 2 readiness. It needs to know where the application falls short before engaging a formal compliance auditor.
Common findings:
Sensitive fields stored without encryption at rest
Detailed error messages exposing stack traces and database structure
Service account with broad project-level permissions
No audit trail showing who accessed patient records
What happens next: The team gets a prioritized list of technical control gaps to close before the formal compliance audit. That reduces the risk of costly findings and delays during certification.

Frequently Asked Questions
What is a web application security audit?
It's a structured assessment of a web application's code, configuration, APIs, and hosting environment to identify security vulnerabilities, rate their severity, and recommend fixes.
How much does a web application security audit cost?
A Focused Security Audit starts at $799, and a Combined Security Audit starts at $1,999. Enterprise assessments are priced by scope. The final price is fixed after a free scoping call.
How long does a security audit take?
A Focused Security Audit takes 5–7 business days. A Combined Security Audit takes 2–3 weeks, depending on application size.
What's the difference between a security audit and a penetration test?
A penetration test simulates an external attack to see what can be exploited. A security audit is broader: it reviews code, configuration, access control, and cloud setup to find root causes and recommend fixes. Our Combined Security Audit includes testing of the running application.
Will testing affect my live application?
We recommend testing in a staging environment that mirrors production. If production testing is required, we agree on safe testing windows and methods in writing beforehand.
Do you follow OWASP standards?
Yes. Our methodology is aligned with the OWASP Top 10, OWASP API Security Top 10, and OWASP ASVS, with findings classified by CWE and prioritized using CVSS-based severity.
Will you sign an NDA?
Yes. We sign an NDA and a written testing authorization before any access to your code or systems.
Can the report help with SOC 2 or enterprise security questionnaires?
Yes. The report provides evidence of an independent security assessment and helps you answer questionnaires accurately. A security audit is not a SOC 2 certification itself, but it helps you prepare for one.
Do you retest after we fix the issues?
Yes. The Combined Security Audit includes one free retest within 30 days, and retesting can be added to any other plan.
