See What Attackers See

A penetration test is a hands-on security exercise where our team attempts to breach your defenses the same way a real attacker would. You get a clear picture of what's exploitable, what's at risk, and exactly what to fix.

Network Penetration Test

Map & Test Your Entire Infrastructure

We identify every device, service, and potential attack vector in your network, then test them the way a real attacker would.

  • Internet
  • Firewall
  • Router
  • Web Server 1
  • Web Server 2
  • App Server
  • Database 1
  • Database 2
  • Admin Panel

Test Types Explained

External vs Internal Penetration Testing

Understand the difference and choose the right test, or combine both for complete coverage.

Type Description
------- ----------
External Test Outside-In Attack Simulation
Internal Test Inside-Out Attack Simulation

External Penetration Test

  • Outside-In Attack Simulation
  • Simulates an attacker with no prior access to your network, targeting internet-facing systems.

Attacker Perspective: Attacker on the internet

Primary Targets

  • Web applications
  • Email systems
  • VPN gateways
  • Cloud services
  • Public DNS
Duration Avg Testing Duration Avg Critical Findings Retesting Available
2-4 Weeks 2-4 90 Days Yes

Key Benefits

  • Identifies perimeter weaknesses
  • Tests internet-facing attack surface
  • Most commonly required by insurers
  • Validates firewall and edge configurations

Best For:

Organizations wanting to assess their public attack surface. Most commonly required by cyber insurers and compliance frameworks like PCI DSS.

Web Application & API Testing

See How Attackers Exploit Your Code

Our web application and API penetration tests target injection, authentication bypass, and data exposure, the vulnerabilities scanners miss.

  • SQL Injection
  • Cross-Site Scripting (XSS)
  • Remote Code Execution
  • Server-Side Request Forgery
// Vulnerable Code
const query = "SELECT * FROM users WHERE id = '" + userId + "'";
// Attack

Impact: Full database access, data theft, authentication bypass

Our Methodology

Our Testing Methodology

We follow industry-standard methodologies (PTES, OWASP, NIST) adapted to your specific environment and threat model.

  1. Scoping & Rules of Engagement (Phase 1)
  2. Reconnaissance (Phase 2)
  3. Testing & Exploitation (Phase 3)
  4. Analysis & Reporting (Phase 4)
  5. Debrief & Remediation Support (Phase 5)

Reconnaissance

Gather information the way an attacker would — OSINT, DNS enumeration, exposed services, and technology fingerprinting.

Key Activities

  • OSINT collection
  • Network enumeration
  • Service identification
  • Technology fingerprinting

Aligned Frameworks

  • PTES
  • OWASP
  • NIST

Actionable Reports, Not Just Findings

Our reports are written so your IT team knows what to fix and your leadership knows what's at stake. Every vulnerability includes severity, evidence, and specific remediation steps.

  • Executive summary for leadership, board, and insurers
  • Technical findings with proof-of-concept evidence
  • Risk prioritized by exploitability and business impact
  • Specific, actionable remediation steps — not generic advice
  • Retest verification to confirm fixes

Pen Testing for Every Framework

Our penetration testing meets the requirements of major compliance frameworks. We know exactly what each standard demands.

  • PCI DSS
  • HIPAA
  • SOC 2
  • CMMC

PCI DSS

Testing Requirements

  • External penetration test annually
  • Internal penetration test annually
  • Segmentation validation
  • Application-layer testing
  • Quarterly ASV scanning
