Cybersecurity & Penetration Testing Services

ISO 27001 & 9001 Certified

Certified under ISO/IEC 27001:2022 and ISO 9001:2015, so every engagement follows audited information security and quality processes. View our certifications

Manual, Evidence-Based Testing

Our testers go beyond automated scans. Every finding is manually verified and backed by proof, with clear steps to reproduce it.

Confidential by Default

We sign an NDA before work begins and handle your data, credentials and findings with strict access controls throughout the engagement.

Remediation Support & Retesting

We help your team understand and fix each issue, then retest to confirm the vulnerabilities are actually closed.

How We Work

A simple, transparent process for every engagement, whether it is a single web application test or a full red team exercise.

01

Scope

We learn your goals, agree on the assets in scope and the rules of engagement, and sign an NDA.

02

Test

Certified testers combine manual techniques with trusted tools to find and safely validate real vulnerabilities.

03

Report

You get a clear report with business impact, evidence, severity and step-by-step remediation guidance.

04

Retest

After your team fixes the issues, we retest to confirm every reported vulnerability is closed.

Frequently Asked Questions

What is the difference between VAPT and penetration testing?

A vulnerability assessment (VA) scans broadly to identify known weaknesses, while penetration testing (PT) manually exploits them to prove real-world impact. VAPT combines both, giving you full coverage plus evidence of what an attacker could actually do.

How long does a security assessment take?

It depends on the scope, such as the number of applications, APIs, hosts or cloud accounts. After a short scoping call we share a fixed timeline and quote in our proposal before any work starts.

Will testing disrupt our live systems?

Testing is planned around agreed rules of engagement and testing windows. We avoid destructive techniques on production unless you approve them, and we stay in contact throughout the engagement.

Do you sign an NDA?

Yes. We sign a non-disclosure agreement before the engagement begins, and all data, credentials and findings are handled confidentially.

What do we receive at the end?

A report with an executive summary for leadership, plus detailed technical findings with severity ratings, evidence, steps to reproduce and clear remediation guidance for your developers.

Do you retest after we fix the issues?

Yes. Once your team has applied fixes, we retest the reported vulnerabilities to verify they are properly resolved.
