Overview

Automated coverage, human expertise

Web applications and APIs are often the most exposed part of a business, and the most attractive to attackers. Injection flaws, cross-site scripting and broken authentication can all lead to unauthorised access and data breaches if they go unnoticed.

Our web application security service blends regular automated scanning with hands-on testing by experienced consultants. Scanning gives you a steady, repeatable view of known issues, while manual assessments and penetration tests uncover the business logic and access control problems that tools cannot find on their own.

Testing is delivered in partnership with Rootshell Security, a CREST and CHECK accredited provider, and is aligned with OWASP, NIST and the Penetration Testing Execution Standard (PTES). Beyond web apps, testing is also available for APIs, mobile apps on Android and iOS, and desktop applications.

What's included

Choose the right level of testing

From monthly scans to in-depth manual reviews, each option targets a different need and budget.

Monthly automated scanning

A cloud-based, vendor-agnostic scanner runs every month with dynamic reporting, and analysts add context to filter out false positives.

Full OWASP assessment

An in-depth, white-box review against the OWASP testing guide, including authorisation and business logic analysis across up to three user roles.

Essential OWASP Top 10 assessment

A faster, cost-effective white-box review focused on the OWASP Top 10, ideal when time or budget is tight or you have several apps to cover.

Web application penetration testing

A black-box test from an outsider's perspective in which testers identify, exploit and chain vulnerabilities to demonstrate real access.

Optional testing hours

Add penetration testing hours to your scanning so consultants can investigate notable findings in more depth.

Remediation guidance

After each test, our testers help your developers understand and fix what was found.

How it works

How we work with you

  1. Understand your needs

    Tell us about your applications and security requirements so we can recommend the right mix of scanning and testing.

  2. See the platform

    We show you a personalised demo of the vulnerability management platform where your results will be delivered.

  3. Onboard

    Previous vulnerability data can be imported, and the service is tailored to your goals, risk appetite and budget.

  4. Scan and test

    Monthly scans run alongside scheduled manual assessments and penetration tests across your agreed scope.

  5. Report and remediate

    Findings, risk levels and remediation steps appear in real time on the platform, with our testers on hand to advise.

Benefits

Why it works

Depth and breadth

Automated scanning keeps coverage consistent while manual testing finds the complex, logic-based flaws scanners miss.

Recognised methodologies

Work follows OWASP, NIST and PTES, giving you assurance that testing is thorough and repeatable.

Real-time results

No waiting for a static PDF: vulnerabilities, risk ratings and fixes are visible on the platform as soon as they are confirmed.

One annual programme

A 12-month package brings all three manual tests together with monthly scanning, managed in one place.

FAQ

Frequently asked questions

What is web application security testing?

It is the process of examining an application to find weaknesses an attacker could exploit, using both automated tools and manual techniques. Areas of focus include input validation, authentication and session management.

What are the main threats to web applications?

Common risks include injection flaws, cross-site scripting and broken authentication. Left unaddressed, these can lead to unauthorised access and data breaches.

What is OWASP?

OWASP is a non-profit organisation that publishes widely used guidance on web application security, including the well-known OWASP Top 10. Our testing follows its frameworks.

What is the difference between a scan, an assessment and a penetration test?

A scan is automated and detects potential issues without confirming their impact. An assessment is manual and authenticated (white-box), focusing on areas such as sessions and business logic. A penetration test is manual and unauthenticated (black-box), simulating an attacker who tries to exploit and chain vulnerabilities.

Can you test larger or more complex applications?

Yes. Scopes involving more than three user roles, mobile code, rich internet applications or very large applications and APIs are scoped by a consultant so the testing fits the application.
