Grey Shield delivers elite penetration testing, red team operations, and comprehensive security audits to safeguard your enterprise from real-world cyber threats.

Internal and external network assessments, firewall analysis, VPN audits, and lateral movement simulations.
Full-scope adversary simulation — physical intrusion, phishing, C2 operations, and covert data exfiltration exercises.
AWS, Azure, and GCP misconfiguration reviews, IAM privilege escalation paths, S3 exposure, and container security.
Android and iOS security testing — reverse engineering, insecure data storage, improper session handling, and certificate pinning bypass.
Targeted phishing campaigns, vishing, pretexting, and physical security tests to audit your human firewall.
Real engagements, real impact — all client details anonymized per NDA.
Identified a chained IDOR + JWT misconfiguration allowing full account takeover of any user without credentials. Affected 800K+ accounts.
Exploited an unpatched Apache Struts instance in a healthcare portal serving 200+ hospitals. Full RCE with PHI data access.

Grey Shield is a team of offensive security specialists, former bug bounty hunters, and military-grade cybersecurity experts with a single mission: making your organization unbreakable.
We don't run automated scanners and call it a pentest. Every engagement is manual, methodical, and adversary-grade — because real attackers don't run Nessus and leave.
