About us

Security expertise, backed by real engineering.

Nehals Limited is a UK-based IT security and web development company. We have worked in IT since 2013, helping businesses protect their brands, systems and data from cyber attacks while building fast, secure websites.

Who leads the work

Every engagement is led by Sajjan Singh Nehal — a penetration tester with 3+ years of security experience across the UK and Canada, a year of system administration, and three years of full-stack development. That combination means vulnerabilities are not just found; they come with practical, developer-ready remediation guidance.
