What is web application penetration testing?
Web application penetration testing is a simulated security assessment designed to uncover weaknesses in a business's web applications. Penetration testing helps identify vulnerabilities that could enable attackers to:
- Gain access to user accounts
- Compromise application data
- Cause reputational damage
- Disrupt web application functionality
Our CREST-accredited testers use a combination of manual techniques and automated tools to thoroughly assess application security, pinpointing vulnerabilities that real-world attackers actively exploit. Web application penetration testers leverage deep expertise in app development to identify and address common risks such as:
- Injection flaws allowing unauthorised access
- Authentication weaknesses enabling account takeovers
- Broken access controls granting improper permissions
- Security misconfigurations leaving entry points open
- Database interaction errors exposing sensitive data
- Input validation problems enabling injection attacks
- Flaws in application logic that can be exploited
Comprehensive penetration testing is crucial to uncover these vulnerabilities before they are discovered and exploited by malicious actors. Our experienced testers methodically assess the security posture and recommend remediation measures to keep your web applications secure.

Frequently Asked Questions
What is penetration testing?
Pentesting, also known as penetration testing, is a critical security practice where a security professional adopts a hacker’s mindset to identify security issues in an organisations IT infrastructure. Penetration testing simulates real-world hacking activities, comprehensively evaluating your digital defences. By engaging in pentesting, businesses can uncover and remediate vulnerabilities before malicious hackers exploit them.
What’s the difference between manual and automated pentesting?
Automated pentesting and vulnerability scanning relies on software tools to quickly assess for known vulnerabilities. Manual pentesting uses experts to identify complex vulnerabilities, tests in real-time and uncovers subtle issues that automated tools might miss. We believe in manual-first testing, and investing in developing talent through a structured and rigorous training programme. That's how we keep the quality of our tests so high.
Do I need a penetration test?
A penetration test is the best way to know for sure if your organisation is an easy target for hackers. The test will show you both how strong your cyber defences are, but what the potential outcomes of a breach could be. It can also ensure compliance with security regulations and enhance customer trust through demonstrated security commitment. Recent research reveals that the average breach now costs $4.35 million, with global cybercrime expenses projected to surge by 23% annually. By 2027, these costs could reach a staggering $23.84 trillion per year. This alarming trend underscores the critical need for robust cybersecurity measures. Penetration testing is a vital cyber security solution. As cyber attacks grow more sophisticated and frequent, proactive testing of your defences becomes even more important. Safeguard against potential breaches and avoid devastating financial impacts. Implementing pentesting services is no longer optional – it’s a necessity for many businesses seeking to protect their assets and reputation.
What should I get pentested?
All types of computer systems, networks, applications, and devices that are used to store, process, or transmit sensitive data should be tested. This includes web applications, mobile applications, wireless networks, cloud-based systems, and IoT devices. The scope of the penetration test should be determined by the organisation's risk assessment and compliance requirements. It's important to test all systems and applications that have access to valuable data to ensure that they are secure and protected against potential attacks.
How much does a pen test cost?
The cost of a penetration testing service can vary depending on the scope, duration, and complexity of the project. Generally, factors that can affect the cost of a penetration test include the number of systems to be tested, the depth and breadth of the testing, the type of testing required (e.g., web application, network, mobile), and the level of reporting and follow-up support needed. Our transparent, hourly billing means that everybody pays the same rate, and we quote to the nearest hour, not the nearest day. If you are interested in obtaining a quote for a penetration test, you can get an instant quote from our quote builder.
What's the difference between vulnerability scanning and pentesting?
A vulnerability scan is done using an automated tool to sweep your systems for known vulnerabilities. Penetration testing is a highly skilled, manual process in which a tester finds and attempts to exploit a vulnerability.

How many scoping questions do you ask? / How do you scope a pentest?
OnSecurity requires just two simple scoping questions to determine the scale of your test. We then use an algorithm to generate you an estimated quote in just a few clicks.
Are your pentests disruptive? Can I continue working while the test is being done?
Our tests are carried out in a safe and controlled manner by experienced testers, so you can continue with work as normal. We tell you about the security issues we find in real-time, so you can fix them before criminals have a chance to exploit them.
Can I speak to my tester directly?
Yes! You can chat directly to your tester in-platform or via Slack during the test.
How can I be sure my test is cost effective?
OnSecurity works in hours, not days, so you get a quote based on the actual time your test will take, without any padding or rounding up to the nearest day. Plus, we report as we go - so no waiting around while a tester spends days writing up a report before you can action any findings.
When will I be notified of findings?
Our testers report in real time as they test, so you can get notified immediately when something is found, instead of having to wait until the test is complete and a report written up.
Do you offer free retesting?
Yes! OnSecurity will retest any findings you've fixed for free, just book them in directly through our platform within 7 days of the test completion date.
How long does a pentest take?
How long a test will take will depend on the size of your target and its function. We ask 2 simple scoping questions to gauge the complexity of your environment which then informs the time we think it will take to test.
What if I need to cancel or reschedule a test?
No problem! We know that things don't always go to plan, so we don't charge you any fees to cancel or reschedule a test.
