Four vendors, no owner
A developer, a hosting provider, a security tester and an SEO agency who have never spoken to each other. When something breaks, everyone is confident it is someone else's layer.
Manual web & API penetration testing
Security built into delivery, not bolted on at the end.
We find the authentication, authorization and business-logic flaws automated scanners cannot see, then help you fix them, verify them, and keep the platform they run on reliable.

The problem
Platforms rarely fail dramatically. They fail at the seams.
Growing businesses end up with a developer, a hosting provider, a security tester and an SEO agency who have never spoken to each other. The gaps between them are where breaches, downtime and lost traffic actually come from.
Security arrives last
Testing gets booked the week before launch, when the finding that matters is architectural and there is no time left to fix it properly.
Reports nobody can action
A PDF of scanner output with severity colours and no reproduction steps. The team argues about the count instead of fixing anything.
Deployments held together by memory
Releases work because one person remembers the sequence. Monitoring is a customer email. Backups have never been restored.
What we do
All servicesFour connected layers, one accountable team
Cybersecurity leads the brand. The rest exists because a finding you cannot deploy a fix for is not really fixed.
Why the order matters
Each layer rests on the one below it. A page cannot rank if the site is down. A site cannot stay up if the infrastructure is undocumented. And infrastructure is only as trustworthy as the last time somebody checked it properly. Most agencies sell one of these layers and hand you the problem at the boundary. We cover all four so that the boundary is somebody’s job.
You can still book one layer on its own. Most clients start that way.
Depth, not checkboxes
What we actually test
A scanner recognises patterns. It has no opinion about whether a viewer-role user should be able to approve an invoice, or whether the price in a checkout request should be trusted.
Authentication & account lifecycle
- Registration, email verification and pre-registration collisions
- Password reset token generation, binding, reuse and expiry
- OTP and one-time code strength, replay, flooding and brute force
- Session issuance, fixation, termination and post-reset invalidation
- Email and phone change flows, re-authentication and notification
Authorization & tenancy
- Horizontal access: reading and writing other users' objects
- Vertical access: privilege escalation between roles
- Multi-tenant isolation across every data path, not just the UI
- Role-based access control consistency between web and API
- Team invitations, seat limits and permission inheritance
APIs
- Access control on every endpoint, including undocumented and legacy versions
- Excessive data exposure and over-broad serializers
- Mass assignment and unexpected parameter handling
- Input validation, injection surfaces and file handling
- Rate limiting, quota enforcement and abuse resistance
Business logic
- Checkout and pricing manipulation
- Quantity, discount, credit and refund abuse
- Workflow sequence bypass and skipped verification steps
- Plan, trial and usage-limit evasion
- State transitions that were never drawn on the diagram
How engagements run
Scoped, authorized, evidenced, verified
No surprises about what was tested, what it means, or whether the fix actually worked.
01
Scope & authorize
We agree exactly what is in scope, which roles and environments are covered, and what is excluded. Security engagements get written rules of engagement before anything is touched.
02
Model the system
Before testing starts we map roles, permissions, workflows and the points where money, data or trust change hands. That model is what turns a 200 response into a finding.
03
Do the work manually
Tooling supports the work; it does not replace it. Every finding is verified by hand, with the request, response and steps captured as evidence.
04
Report in plain language
Severity with the reasoning visible, impact described for your business, and remediation specific enough to become a ticket. Plus a debrief call to walk through it.
05
Verify the fix
A finding is closed when someone re-runs the attack and it fails. The retest result is recorded in the report. That is the part your customers want to see.
Proof of work
A business-logic flaw in a large consumer platform: found, reported responsibly, validated and paid
A weakness in a checkout workflow that let order pricing be manipulated. Submitted through the vendor’s public bug bounty program, validated by their security team and rewarded. It is exactly the class of issue a scanner cannot describe, because every request involved is a perfectly valid one, in the right order, from a legitimate account.
The vendor is not named and the report is not reproduced here: it has not been publicly disclosed, and naming it would breach the program’s disclosure terms. Client findings are confidential on the same principle, and are discussed publicly only with written permission.

Case studies
All case studiesRedacted findings, and how the work runs
Real security findings with the client, the product and the payloads removed, alongside honest walkthroughs of the DevOps, web and search work. Nothing here is published while it is under disclosure terms.
OAuth misconfiguration that allowed one account to be linked to another
Single sign-on was configured so that the identity returned by the provider was trusted more than the account it was being attached to. The result was an account linking path that let one identity end up in control of a different user's account. This is the class of issue that reads as a configuration detail and behaves as a full account takeover.
OAuth and single sign-on misconfigurationRead it
SQL injection and stored cross-site scripting behind an authenticated interface
Two classic injection classes, both reachable only after login, which is why neither had ever been reported by an unauthenticated scan. The database defect exposed data across the whole application. The scripting defect ran in the browser of whoever reviewed the affected record, which in this product was always an administrator.

LeadFounder and Lead Penetration Tester
Web and API penetration testing, bug bounty research
Raheel is a penetration tester and bug bounty hunter who works on web applications and the APIs behind them. His testing concentrates on authentication and account lifecycle flows, OAuth and single sign-on configuration, authorization boundaries between roles and tenants, and injection classes such as SQL injection and cross-site scripting. He has tested more than 25 applications and reports findings through public bug bounty programs alongside client engagements. He founded Nextralix so that a client could get the test, the fix and the infrastructure it runs on from one accountable team rather than four vendors.

Why teams choose us
Specialist depth, without the agency layer in between
Security is part of delivery
The same team that tests your application can fix the server configuration, the deployment pipeline and the website that sits in front of it. Findings do not get lost in a handover.
Manual testing, documented properly
Automated scanning has its place in CI. It is not what you are buying here. You are buying someone who reads your application like an attacker and writes down exactly what they did.
No fear-based selling
No countdown timers, no invented breach statistics, no promises that cannot be proven. Clear scope, honest limitations, and a quotation you can read in one pass.
Built for teams without a security function
Most clients do not have a CISO to translate. Reports are written so a founder can make a decision and an engineer can act on it, from the same document.

How to scope a web application penetration test without overpaying
Most quotes vary because the scope is vague, not because testers disagree. Here is what actually drives the number, and what to prepare before you ask.

Why a vulnerability scanner will not find your worst bug
Scanners are good at recognising patterns they were taught. The findings that actually cost money are the ones that look like normal application behaviour.

Common questions
The things clients ask before they commit
If your question is not here, ask it directly. You will get a straight answer rather than a discovery call.
How is manual testing different from running a vulnerability scanner?
A scanner recognises patterns it was trained on: missing headers, known CVEs, obvious injection. It cannot tell you that a viewer-role user can approve their own invoice, that a discount stacks twice, or that changing an ID in an API path returns another tenant's data. Those need someone who understands what your product is for. Both are useful; they answer different questions.
What will the report contain?
Confirmed scope and rules of engagement, an executive summary a non-engineer can act on, each finding with reproduction steps and evidence, severity with the reasoning shown, business impact, specific remediation guidance, and the results of the retest once fixes land.
Will testing affect our production environment?
Testing normally runs against staging. Where production is unavoidable, we agree the window in advance, avoid destructive techniques, keep request volumes low, and stay reachable throughout so anything unexpected stops immediately.
Is retesting included?
Yes. One standard retest of reported findings is included with full penetration test packages, and the verification result is recorded in the report. Extra or delayed verification cycles are available separately.
How is our data kept confidential?
Findings, credentials and client data are treated as confidential, stored only for as long as the engagement requires, and never disclosed or reused as a case study without written permission. We are happy to work under your NDA.
Do you work with companies outside Pakistan?
Yes. Delivery is remote and most clients are in the United States, United Kingdom, Canada, Germany and Australia. Scheduling is arranged around your working hours, not ours.
Tell us what you are building, and what must not break.
Send the scope: the application, the roles, the environment and the deadline. You get a written scope and a fixed quotation back, not a discovery-call funnel.
