Learn moreHow we work
A Clear, Repeatable
Testing Methodology
Every engagement follows the same disciplined process, aligned to OWASP, PTES, and NIST testing standards.
01
Scoping & Recon
We define targets, rules of engagement, and gather intelligence to map the real attack surface.
02
Exploitation
Manual testing and controlled exploitation validate which vulnerabilities are genuinely exploitable — not just theoretical.
03
Reporting
A prioritised, business-context report with clear severity ratings, evidence, and step-by-step remediation guidance.
04
Remediation Retest
Once fixes are deployed, we retest to confirm every reported issue is closed before final sign-off.
Common questions
Frequently Asked Questions
What is penetration testing?
Penetration testing (pen testing) is an authorised, simulated cyberattack against a system, network, or application, carried out to identify exploitable vulnerabilities before real attackers can find and use them.
How long does a penetration test take?
Most engagements run 1–3 weeks depending on scope. Web application and network tests typically take 5–10 business days; larger red team operations run several weeks.
What's the difference between VAPT and red teaming?
VAPT systematically identifies and validates vulnerabilities within an agreed scope. Red teaming is a broader, objective-driven adversary simulation that tests people, process, and technology together — often without the defending team's advance knowledge.
Do you provide a remediation retest?
Yes. Every Grey Shield engagement includes a remediation retest after fixes are deployed, to confirm reported vulnerabilities have been resolved before final sign-off.
Does Grey Shield help with compliance like ISO 27001, SOC 2, or DPDP?
Yes. We run structured gap assessments against ISO 27001, SOC 2 Type II, and India's DPDP Act, delivering a prioritised remediation roadmap alongside standard penetration test reporting.
