Secure Your Web Applications with Confidence

Web Application Security Testing & Penetration Testing Services

Your web application is one of the most exposed parts of your business. PlutoSec's certified testers manually assess your application for authentication flaws, broken access control, injection vulnerabilities, and business logic gaps, so you can fix what matters before someone else finds it first.

  • Web Application Security Experts

    OSWE and CEH certified testers bring deep expertise in modern web application security.

  • Real World Approach

    We exploit real vulnerabilities like SQL injection and broken access control, not just scan for them.

  • Actionable Reporting

    Every finding maps to the OWASP Top 10 with clear steps developers can act on immediately.

  • Confidential & Secure

    Application data and credentials remain protected under strict NDA throughout testing.

About Web App Pentest

Your Partner in Web Application Security

Web application penetration testing is a hands on security assessment where our testers act like real attackers to find weaknesses in your login flows, APIs, forms, and back end logic. Automated scanners catch the obvious issues, but most serious vulnerabilities, like a checkout flow that lets someone change a price, or a user role that can be escalated, only show up under manual testing.

Most businesses run their applications publicly on the internet, which means anyone can probe them at any time. A single penetration test before a launch, a major release, or a compliance audit gives you a clear picture of what an attacker could actually do, not just a list of theoretical risks. Regular testing also keeps pace with new features, since every code change can introduce a new flaw.

Our Testing Methodology

  1. 1.

    Scoping and planning

    We define what's in and out of scope, your goals, and any compliance drivers.

  2. 2.

    Reconnaissance

    We map the application, its technology stack, and entry points.

  3. 3.

    Vulnerability discovery

    We combine automated tooling with manual review to identify weaknesses.

  4. 4.

    Controlled exploitation

    We safely validate that findings are real and exploitable, without disrupting your live environment.

  5. 5.

    Risk analysis

    We rank issues by real business impact, not just a generic severity score.

Frequently asked questions

Answers to the questions we hear most. Still unsure how it applies to your environment? Our engineers are happy to talk it through.

What does a web application penetration test actually cover? 
It covers authentication, access control, input handling, session management, business logic, and server configuration, essentially every way a user or attacker can interact with your application.
How is this different from a vulnerability scan?
A scanner flags known patterns automatically. Our testers manually exploit findings to confirm they're real and assess what an attacker could actually achieve, including logic flaws no scanner can detect.
Do you need access to our source code?
No, but it helps. We can test without it (black box) or with it (white box), depending on the depth you need and your timeline.
Will testing affect our live application?
We schedule testing windows with your team and use controlled methods to avoid disrupting uptime or live customer data.
How long does a web app pentest take?
Most engagements run one to three weeks depending on the size and complexity of the application.
Do you retest after we fix the issues?
Yes, retesting is included, so you have documented proof that vulnerabilities are closed.
