Web Application Penetration Testing

Your app is the front door. We try to break in.

At CyberGuards.ai, we deliver web application penetration testing services that simulate real-world attackers targeting your applications — with no inside access and no assumptions. Our goal: to discover exploitable vulnerabilities before someone else does.

Unlike automated tools, we don’t just scan. We exploit.

We Don’t Scan. We Exploit.

Our ethical hackers approach your web app the same way a malicious outsider would: from the outside, without credentials, insider knowledge, or context.

We uncover weaknesses in:
Session Management — insecure cookies, weak tokens, session hijacking
Broken Access Controls — privilege escalation, horizontal/vertical bypass
Insecure Input Handling — SQL injection, XSS, command injection
Business Logic — workflow bypasses, payment manipulation, abuse of intended functions
Chained Exploits — linking small flaws into attack paths with real business impact

Every finding is manually validated and backed with proof-of-concept exploits — no false positives, no theoretical risks.

How It Works

Everything we deliver is verified. Nothing is guesswork.

Discovery

We fingerprint your app’s structure and endpoints

Exploitation

We manually test for ways to break in, pivot, escalate, and extract sensitive data.

Reporting

You receive a detailed report with validated findings, severity ratings, screenshots, and developer-ready remediation steps.

Re-testing

Once you patch, we confirm the fixes are closed — at no extra cost.

Why Web App Penetration Testing Matters

Modern applications are complex, fast-moving, and always under pressure to ship. That’s when mistakes slip in — and attackers take advantage.
82% of breaches in 2024 originated from internet-facing assets (Verizon DBIR).
Compliance frameworks like SOC 2, PCI DSS, and HIPAA mandate web application security testing.
Automated scanners can’t detect business logic flaws or chained exploits.
Our web app pentesting services help you discover vulnerabilities early, often, and realistically — before they become costly incidents.

FAQs

What specific vulnerabilities does web application pen testing find that SAST or DAST tools miss?

Static (SAST) and Dynamic (DAST) tools are great for finding common code flaws and known vulnerabilities. Our manual web application penetration testing excels at uncovering complex business logic flaws, authentication bypasses, and multi-step attack chains that require human reasoning and creativity to exploit.
Do you test Single Page Applications (SPAs) built with frameworks like React or Angular?

Absolutely. Testing SPAs requires a specialized understanding of how they communicate with back-end APIs. Our experts meticulously test the API endpoints, authentication tokens, and client-side logic to identify vulnerabilities specific to the SPA architecture.

What is your process for testing the security of third-party APIs integrated into our web app?

We assess the security posture of integrated third-party APIs by analyzing how your application interacts with them. We test for insecure direct object references, broken access control, and excessive data exposure through these integration points, which are a common source of breaches.

Beyond OWASP Top 10, what other frameworks do you use for web app testing?

While the OWASP Top 10 is a baseline, our testing is guided by the comprehensive OWASP Application Security Verification Standard (ASVS), which provides a much more detailed and rigorous set of security requirements. We also incorporate insights from the MITRE ATT&CK® for Enterprise framework to simulate advanced persistent threats.

How do you test modern, cloud-native applications built on serverless architectures (e.g., AWS Lambda, Azure Functions)?

We specialize in cloud-based penetration testing for modern architectures. Our approach includes assessing the application itself, its API endpoints, and the cloud service configurations (like IAM roles and function triggers) that, if misconfigured, could lead to data compromise. We use specialized cloud pen testing tools and custom scripts to evaluate these environments thoroughly.

How do you handle applications that are still in development (pre-production)?

 We highly recommend testing in pre-production stages (a "shift-left" approach). We can test staging environments to identify and remediate security issues early in the SDLC, which is far more cost-effective than fixing them in a live application.

How do you ensure your testing doesn't cause downtime or data corruption in our live application?

Client safety is paramount. We use carefully controlled, non-disruptive testing techniques. For high-risk tests, we first run them in a controlled manner or coordinate with your team during low-traffic periods. We never perform destructive actions without explicit prior approval.

Ready to See Your App Through an Attacker’s Eyes?

Your web app is your business — and your biggest risk. Don’t wait for attackers to find the flaws first.

 CyberGuards.ai delivers web application penetration testing services in California and nationwide that expose vulnerabilities before they’re exploited.
