Who we are

A small team of practitioners, not a scanning service.

XECbuild was started by testers who spent years inside consultancies watching real risk get buried under automated output. We kept the parts that worked, threw out the rest, and built a practice around manual testing and clear communication.

Every engagement is run by the person who writes your report. You talk to the tester, not an account manager, and you hear about a critical finding the day we confirm it.

Himanshu Chaudhary
Founder / Security Researcher
Founder of XECbuild and a cybersecurity researcher focused on penetration testing and vulnerability research. He identifies security weaknesses across web applications, APIs and digital infrastructure, combining technical research, manual testing, reconnaissance and attack surface analysis to uncover the vulnerabilities automated tools alone may miss.

Why XECbuild

Four things we refuse to compromise on.

01
AI & Manual Testing
We leverage AI-assisted analysis alongside deep hands-on manual testing. AI accelerates surface coverage while our senior practitioners uncover complex business logic vulnerabilities.
02
Real world methodology
OWASP and PTES as a floor, then the techniques currently being used against products like yours.
03
Actionable reporting
Every finding carries a working proof of concept, a business impact statement and a fix your team can implement.
04
Responsible disclosure
Criticals reach you within 48 hours of confirmation. Nothing is published without written permission.
Services

From building digital products to testing their security.

We design and develop websites, web applications and the custom tools that do not come off a shelf, in whatever language or framework fits the work.

And we test them the way an attacker would, treating business logic and authorization as first class targets rather than afterthoughts. Development and security in one place, so what gets built is reliable, resilient and secure.

What we test

Four surfaces, tested by hand.

  1. 01

    Web Application Security Testing

    Deep-dive manual testing that uncovers business logic flaws, access control issues such as IDOR, and injection vulnerabilities scanners overlook.

  2. 02

    VAPT & Penetration Testing

    Full assessment across applications, APIs and exposed infrastructure, working outward from every endpoint under agreed rules of engagement.

  3. 03

    Security Reviews & Hardening

    Architecture and configuration pulled apart layer by layer, covering authentication, authorization, headers, secrets and cloud roles.

  4. 04

    Vulnerability Assessment

    Systematic identification and prioritisation based on real-world exploitability rather than raw scanner severity.
