External Penetration Testing
We attack your perimeter the way attackers do.
Your internet-facing assets are an attacker's first stop. We perform black-box reconnaissance and exploitation against your perimeter — the same TTPs real adversaries use, with none of the consequences.
What we test
- ▸Public IP ranges, exposed services, perimeter firewalls
- ▸Web servers, mail servers, VPNs, remote-access portals
- ▸Subdomain takeover, DNS misconfigurations, certificate exposure
- ▸Authentication portals (SSO, OAuth, federation)
- ▸Cloud-edge services (S3, blob storage, public APIs)
- ▸Leaked credentials + breach-data correlation
How we approach this engagement
Each phase is signed into the QSurface provenance chain in real time.
Reconnaissance
Passive OSINT + active scanning. We map your full external footprint before touching it.
Vulnerability Discovery
Combine automated scanning with manual analysis to surface real exploitable issues — not noise.
Exploitation & Validation
We prove findings with safe PoCs. No theoretical risk — actual demonstrated impact.
Reporting & Remediation
Executive + technical reports with the QSurface provenance chain. Retests included.
What you receive
