Application Security

Application Penetration Testing

Manual testing of your web apps, mobile apps and APIs, with fixes your developers can apply

Overview

Find Exploitable Flaws Before Release

We test your web applications, mobile apps and APIs the way an attacker would, for flaws such as SQL injection, cross-site scripting (XSS) and CSRF. Every finding is confirmed, rated by impact and written up with the steps to reproduce and fix it. We work alongside your developers during the test, so serious issues can be fixed before the report arrives.

Approach

Our Three-Step Approach

Step 01

Scoping & Onboarding

We map your application's attack surface with your team, then agree the scope, test credentials and timeline.

Step 02

Pentesting

Our testers probe the application for vulnerabilities, then exploit them in a controlled environment to confirm they are real and show their impact.

Step 03

Reporting

You receive an executive summary for leadership and a technical report with reproduction steps and remediation guidance for every finding.

What you receive

  • An executive summary for leadership
  • A technical report with reproduction steps and a fix for every finding
  • An impact rating for each finding
  • Serious issues raised with your developers during the test, before the report

Common questions

How is an application pentest different from a vulnerability scan?

A scan reports patterns that look like known weaknesses; a pentest proves which ones an attacker can exploit and what they reach. Our testers also check business logic and authorisation, which a scanner cannot judge.

Do you test as a logged-in user?

Usually, yes. Testing with accounts for each role is how flaws such as one customer reading another customer's data are found. We agree the test accounts during scoping.

Can mobile apps and APIs be in scope?

Yes. Web applications, mobile apps and APIs are all covered by this service, and the scope we agree decides which of them we test.

Benefits

Why Test Your Applications

Security

Find and fix the flaws that would expose your customers' data.

Compliance

Produce the penetration test evidence that auditors and regulators ask for.

Trust

Answer enterprise customers and security questionnaires with a current, independent test.

Reputation

An issue found in a test is cheaper to fix, and far less public, than one found by an attacker.

Why us

Why Cyphlon?

01

Findings Ranked by Risk

Each finding is rated by exploitability and business impact, so you know what to fix first.

02

Fits Your Release Cycle

We test web applications, mobile apps and APIs within your DevSecOps workflow, so testing keeps pace with your releases.

03

Your Engineers See the Attack

Reproduction steps show your team exactly how each issue was exploited, so they can recognise the pattern in new code.

04

Direct Access to Testers

You talk to the engineers doing the test, before, during and after it.

1:1 Consultation Call

30 min Google Meet

An introductory call with our engineers about any engagement: a pentest, continuous testing, managed AppSec, security engineering, agentic AI security or a fractional CISO. We'll ask about your stack, your deadlines and what your customers or auditors expect, and tell you plainly if we're not the right fit.
