What is web application penetration testing?

Web application pen testing is a structured security evaluation of web apps. It focusses on identifying weaknesses, including flaws in application logic, configuration issues, and underlying technologies. This helps to expose potential entry points that could be used by hackers to compromise data or functionality. Our security specialists replicate real attack scenarios to assess how your application behaves under threat.

We blend advanced AI tools with in-depth manual analysis to uncover meaningful security insights across your applications. We thoroughly review application workflows, integrations, and code paths to detect vulnerabilities. Web app pentesting service keeps your application secure against several online threats.

Compliance Readiness

Supports regulatory obligations by validating security controls and industry compliance.

Infrastructure Exposure

Uncover weaknesses introduced through configuration changes or system updates.

Vulnerability Discovery

Reveals exploitable flaws in application logic and access paths before they can be abused.

Policy Validation

Tests the effectiveness of existing security policies against real-world attack scenarios.

Our web application penetration testing service can help you with

Any organisation that depends on web-based platforms to operate, manage data, or engage users faces ongoing exposure to cyber risks. From transactional platforms and regulated industries to service-driven enterprises, online applications remain a prime target for evolving attack methods. Proactive web application security testing of applications identifies security weaknesses before they lead to disruption or loss.

We address vulnerabilities early and ensure businesses can reduce the likelihood of breaches. Whether you’re scaling a digital product or managing complex enterprise systems, regular web app security testing can safeguard your digital ecosystem.

Application Security Testing

Our web application pen testing covers in-depth analysis of application logic, authentication flows, and user interactions to identify exploitable weaknesses.

Infrastructure & Configuration Review

Coding Sprint experts assess your public-facing components, integrations, and configurations to detect exposure points across the application environment.

Remediation & Risk Advisory

We prioritise guidance to help your development and security teams address issues and strengthen long-term resilience.

We implement OWASP web application penetration testing methodology

Our testing methodology is aligned with the Open Web Application Security Project (OWASP) framework. We ensure your application is evaluated against globally recognised standards. Each website penetration testing assessment follows a structured, risk-driven approach mapped to the OWASP Top 10 categories. We validate findings through automated and manual testing to uncover vulnerabilities.

Access Control Weaknesses

Our experts verify permission models to prevent unauthorised access to data.

Injection Vulnerabilities

Input validation to reduce and eliminate code or database injection attacks.

Security Misconfigurations

Assessment of application and environment settings that could increase exposure to exploitation.

Authentication & Identity Failures

Check authentication flows, session handling, and access controls for weaknesses.

Logging & Monitoring Gaps

Evaluate security logging and monitoring to identify and investigate threats.

Cryptography & Data Protection

Evaluation of encryption mechanisms used to safeguard sensitive data at all times.

Insecure Design Patterns

We review architectural and workflow decisions that lead to system security weaknesses.

Outdated or Vulnerable Components

Identification of insecure third-party libraries, frameworks, and dependencies.

Software & Data Integrity Risks

Validate and update mechanisms, dependencies, and integrity controls to prevent tampering.

Server-Side Request Forgery (SSRF)

Testing of server-side requests to eliminate the risks of malicious attacks.

What Our Customers Say

It always feels great when customers are delighted with our work. Below are some of the nicest things we have heard from the clients.

Excellent services

What stood out with Coding Sprint was mainly how they managed communication and kept things moving within the agreed budget and timelines. It just made the whole process feel a bit more in control.

Since the website went live, we’ve had feedback from customers saying it feels easier to use. Also, making updates on our end has become simpler than before, which helps day to day. [+]

They kept in touch via Campfire, and we had weekly Zoom calls as well, which helped keep everything aligned. Overall, I’d say the value for what we spent has been good.

Luisa Coates Thermapen

Responsive and Professional...

The Coding Sprint team is responsive and professional. They built our B2B website quickly, and it's working well. We are happy with the web design and performance of our site. Good work.

Jeremy Brandon

Excellent services

Excellent services and great prices. Business site design done and delivered within two weeks. I would recommend them to anyone.

Karen Gore

Big Role in helping.....

Over the last year, Coding Sprint have played a big role in helping us move things forward as a business. They supported us in building and launching our main product, which was a pretty important step for us.

Avatar is now up and running, and a lot of that really comes down to how they managed both the technical work and the delivery side of things.

Jeff Nogosek

Excellent services

Using Coding Sprint’s dedicated development setup has worked well for us so far. It allowed us to scale the team fairly quickly and gave us the flexibility we actually needed at the time.

Priya, in particular, has been a great addition. She brought in useful knowledge and has been able to deal with our development requirements without too many issues.

Garth Hoggins UBT (EU) Ltd

Quality of work

Coding Sprint turned out to be a good fit for what we were looking for. We needed a development partner we could rely on to deliver on time and within budget, and they’ve mostly managed to do that.

We’ve been really happy with the quality of work overall, and they’ve been open to feedback, especially when we’ve asked for design changes or iterations. [+]

It’s been easy working with them, pricing is clear, communication is straightforward, and delivery has been consistent.

How often should web application penetration testing be performed?

The ideal testing frequency depends on:

How critical is your application?
How often does the system change?
Any regulatory obligations you must meet.

Regular testing ensures new vulnerabilities are identified as your application evolves.

Penetration testing is strongly recommended, at least once per year and after major feature releases or architectural changes.

What is the difference between vulnerability scanning and web application penetration testing?

How much does web application penetration testing cost?

What types of web applications can be tested?

Will penetration testing disrupt live systems?

Penetration testing is designed to be controlled and non-disruptive. We plan carefully to minimise impact on availability and performance, especially for production environments.
