Find flaws in your web platforms and apps

Uncover hidden flaws in your web apps — from session handling to access controls — through in-depth security reviews.

Web Application Penetration Testing

Spot and resolve weaknesses in your online platforms

Your applications are front-facing and high-risk — that’s why proactive testing is essential. At Cythera, we evaluate your web apps with and without authentication to identify flaws attackers could exploit, including insecure coding practices, session risks and permission gaps. With clear reporting and practical steps to resolve issues, you’ll be ready to respond before any real damage is done.

Highlights serious vulnerabilities across public and user-level access
Assesses app logic and functionality from a security lens
Delivers readable reports with prioritised, realistic solutions

Service detail

Web application penetration testing that exposes real risks

Can your web applications withstand actual attacker tactics? We test them using real-world methods to spot weaknesses early.

Deep-Dive Application Testing.

Beyond scanners, into real-world risk. Our testing explores how your app behaves under pressure

Revealing flaws in logic, role handling and security controls that automation misses.
Simulate adversary tactics from the ground up
Find logic and access flaws across user journeys
Test data handling and sensitive input validation

Our delivery process

How is it delivered

We tailor each web application test to suit your application’s specific architecture and business logic, while following a clear and standardised testing process from start to finish.

Scope and prepare

We establish clear testing parameter to avoid confusion during execution.

Simulate real-world attacks

Our testers simulate real-world attacks to identify issues and other critical vulnerabilities.

Report and remediate

We deliver a clear, ranked report outlining vulnerabilities, their potential impact, and the exact actions you need to take to address them.

Benefits

Real-world testing built for real applications

We test your web app the way attackers would—but with your goals in mind. Our expert-led approach finds real risks and helps you build with confidence.

Real testing, real results

We don’t stop at automation. Our team uncovers logic flaws, insecure workflows, and realistic attack paths that off-the-shelf scanners fail to detect.

Context-aware testing

No two apps are the same. Our testing is customised to fit your tech stack and workflows, ensuring you get meaningful, targeted insights.

Reports that make sense

You’ll receive concise, practical findings with straightforward instructions—no jargon, no noise, just clear steps to strengthen your security.

Frequently asked questions

From risk assessment to rapid response - we’re with you every step of the way.

How does Cythera perform web application penetration testing?

We use a clear, two-phase testing process - first mapping scope and user roles, then emulating attacks from inside and outside. You'll get a practical report with clear remediation guidance.

How does this differ from relying on automated scans?

Scanners can't spot complex issues in logic or input handling. Our testers use black-box techniques to mimic real attackers, uncovering vulnerabilities only human insight can reveal.

What is web application penetration testing?

Web app pen testing simulates attacker behaviour to reveal security flaws in your application, such as broken authentication, injection bugs, or insecure sessions. These insights help developers patch weaknesses before they're exploited in the wild.

What kinds of vulnerabilities can be found?

We test for critical flaws such as insecure authentication, input handling vulnerabilities, privilege escalation paths, and weaknesses covered in the OWASP Top Ten. Our reports include clear, step-by-step remediation guidance for each finding.

Why is penetration testing important for web applications?

Web applications are often your most exposed assets. Pen testing helps uncover hidden flaws like broken authentication, data exposure, and access control gaps that could be exploited if left unchecked.
