CYTHER

Common Types of Penetration Testing

While these categories represent our most frequently requested services, Griffin Cyber Solutions provides a wide range of additional penetration testing services beyond this list.

External

Our External Penetration Testing checks how easy it is for attackers to break into your systems from the outside, measuring your real exposure and security strength so you can better understand your risk.

Internal

Our Internal Penetration Testing goes beyond simple “smash and grab” tactics by looking at what an attacker could do if they got inside your network, showing where your biggest risks really are so you know what to fix first.

Web Application

Our Web Application and API Penetration Testing goes beyond basic automated scans, delivering an in-depth analysis of your application architecture and uncovering real-world security risks across your digital attack surface.

Mobile App Testing

Our Mobile Application Testing delivers a comprehensive assessment of your app’s ecosystem, covering local data storage, application security, and backend communications.

Physical Site Evaluation

Our Physical Security Testing assesses the strength of your facilities using safe, non-destructive methods to identify gaps in perimeter and internal security controls.

At Cyther we realize no organization will benefit from another checkbox audit. You need measurable assurance — hard data that proves your security investments are working, your controls are effective, and your organization can be trusted.

We deliver that proof using the Open Source Security Testing Methodology Manual (OSSTMM), the only peer-reviewed, scientifically rigorous framework for measuring operational security..

Our services are ideal for organizations seeking measurable assurance when it matters most. Whether you need to prove your security posture during pre-investment due diligence, validate your Zero Trust model through continuous trust measurement, or present verifiable metrics for board reviews and audits, we provide the data to substantiate your case. Our evidence-based assessments not only demonstrate restored trust and reduced risk after an incident but also help justify budget requirements by clearly connecting security performance to measurable business outcomes

Why OSSTMM Matters to Leadership

Traditional security frameworks tell you what to implement. OSSTMM tells you how well it’s working.

With over 21 years of contribution to the OSSTMM’s global development, we are the only US-based firm applying its full methodology to quantify Risk and Trust across your enterprise.

With objective, science-based results, not opinions or compliance checklists. Our approach delivers repeatable, verifiable outcomes grounded in the scientific method, turning your security assessments into measurable metrics you can trust. The data-driven insights we provide support clear communication with boards, facilitate investor due diligence, and simplify your regulatory reporting.

What you Gain

  • Risk Quantification You Can Act On
    We calculate Risk Assessment Values (RAVs) that map vulnerabilities to real operational impact — not theoretical scenarios. You’ll know exactly where your exposure lies and what it costs.
  • Trust Metrics That Prove Resilience
    Our assessments measure trust — the degree to which your systems, processes, and people perform under stress. This isn’t subjective. It’s mathematical.
  • Boardroom-Ready Reporting
    Every report we deliver is designed for executive decision-making. Clear visuals, quantified risk, and actionable recommendations — no jargon, no fluff.
  • Compliance & Performance
    OSSTMM integrates with NIST, ISO, SOC 2, and other frameworks — but goes further by measuring how well your controls actually work, not just whether they exist.
