Offensive Security
Web Application Penetration Testing Services in Pakistan
OWASP-aligned assessments uncovering logic flaws, injection, and auth bypasses.
What it is
Web application testing against your real business logic, not a scanner sweep. We work authenticated as every role you issue, chase broken access control and privilege boundaries between tenants and users, and prove impact by reaching data or actions the role should never touch. OWASP Top 10 is the floor, not the ceiling.
Types of Web Application Pentesting we deliver
SaaS and multi-tenant applications
The highest-value target in this category, because one broken object reference exposes every tenant rather than one account. We test across tenant boundaries, not only within them.
E-commerce and payment flows
Price and quantity manipulation, coupon and voucher abuse, race conditions on balance and stock, and whether the order can be completed without the payment step actually succeeding.
Customer portals and dashboards
Authenticated applications with several roles, where the real risk is a support user reaching an admin function or one customer reading another customer's records.
CMS and plugin-based sites
WordPress, Laravel and similar stacks, where the application code is often sound and the exposure comes from an abandoned plugin, an exposed admin path or a file upload that trusts the extension.
Internal and intranet applications
Applications never meant to face the internet, tested from the position of an employee or a contractor who already has a login.
Single-page applications and their APIs
React, Vue and Angular front-ends where authorisation is often enforced only in the browser, and the API behind it answers requests the interface never makes.
How we do it
-
1
Role and tenant mapping
We inventory every role, permission and tenant boundary the application defines, so we can test across them rather than within one account.
-
2
Authenticated crawling
We map routes, parameters and state transitions as each role, including flows only reachable mid-journey.
-
3
Access control testing
Horizontal and vertical privilege checks on every object reference — the class of bug scanners miss and attackers find first.
-
4
Injection and input handling
SQL, NoSQL, template, command and deserialization paths, plus stored and DOM-based cross-site scripting.
-
5
Business logic abuse
Price manipulation, quantity and coupon abuse, race conditions on balance changes, workflow steps skipped or replayed.
-
6
Proof and retest
We demonstrate real impact with reproducible steps, then re-verify each fix.

What Web Application Pentesting costs
Priced per application, from USD 399 for a single web application.
The figure depends on scope, so we quote one fixed price in writing before any work begins. These are the things that move it:
- How many distinct user roles exist — The expensive part of a web test is authorisation: every function has to be attempted as each role, and as no role at all. An application with five roles is closer to five tests than to one.
- Whether it is one application or several wearing one domain — A marketing site, a customer portal and an admin panel on three subdomains are three applications. Counting them as one is the most common reason a quote elsewhere looked cheaper and the report came back thin.
- The size of the authenticated surface — Public pages are quick. The cost sits behind the login, in the number of forms, workflows and state changes a logged-in user can reach.
- Whether payment, billing or credit flows exist — Money flows need business-logic testing — price and quantity manipulation, coupon abuse, race conditions on balance — which is manual work that no scanner shortens.
- Whether you need a retest — One retest is included. A second round, after a further release, is quoted separately because it is a second round of work.
If budget is tight, scope the application that holds customer data or takes payment and leave the brochure site out. A real test of the thing that matters beats a shallow pass over everything.
Where we deliver Web Application Pentesting
We test web applications for clients across Pakistan — Multan, Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Peshawar and Quetta — and for overseas clients in UK, US, Gulf and Australian time zones. Web application testing is delivered entirely remotely, so where your office is affects the kick-off call and nothing else.

Frequently asked questions
We need accounts — ideally one per role. Most serious web findings are authorization flaws, and those are invisible without credentials on both sides of the boundary you want tested.
Staging is preferred if it mirrors production data-flow and configuration. Where staging diverges meaningfully we test production read-only paths under an agreed window.
Destructive actions are agreed in writing before testing. We use dedicated test accounts, tag the records we create, and hand you a cleanup list at the end.
A single web application starts at USD 399, and a full manual penetration test is USD 1,500. What moves the figure is the number of user roles, whether multiple tenants or environments are in scope, and the size of the authenticated surface. We quote a fixed price in writing after scoping, not an hourly rate.
Five to ten working days for a single application, including the report. Applications with many roles, several tenants or a large authenticated surface take longer. We confirm the window during scoping and we do not start until it is agreed.
The OWASP Top 10 is the floor, not the scope. It describes categories of flaw, not your application. We test it in full and then spend most of the engagement on the things it cannot describe: your authorisation model, your business logic, and the states your workflow can be pushed into.
Yes. Web application testing is non-disruptive by default. Destructive actions, denial-of-service and anything that risks data loss are excluded unless you explicitly request them on a staging copy, and where a finding can only be proven by an action with real impact we stop and ask first.
Tell us and we will retest the affected area. A deployment mid-engagement is normal, but an undisclosed one makes the report describe code that no longer exists, which helps nobody. We ask for a freeze on the tested paths, or notice when one is not possible.
Yes, and it is written for that. An executive summary a non-technical reader can act on, then each finding with impact, CVSS score, reproduction steps, evidence and a specific fix. After the retest we issue an attestation letter stating what was tested and that the findings were verified closed.
No, and the gap is the point. A scanner recognises known patterns — an outdated library, a missing header, a reflected parameter. It cannot know that your "view invoice" endpoint accepts any invoice ID, because to a tool that is a working feature. Broken access control and business-logic abuse are found by people.
Staging is usually the right choice if, and only if, it genuinely mirrors production — same code, same configuration, same roles, realistic data volumes. A staging copy with debug mode on and three test records produces findings you cannot act on and misses the ones you needed. If it does not mirror production, we test production carefully instead.
