Security testing and vulnerability assessment services
At Stone-Knight Security, we take an adversarial approach to protecting your business. Our team combines manual tradecraft with industry-leading automated tools to identify exploitable vulnerabilities across your applications, networks, and cloud environments — before an attacker does.
We assess your true security posture against real-world attack techniques, including privilege escalation, injection attacks, unauthorized access pathways, and sensitive data exposure. Every engagement is scoped to your environment and calibrated to the threats most relevant to your industry.
Our assessments are designed to meet recognized security standards, including PCI DSS penetration testing requirements, NIST frameworks, and sector-specific compliance mandates. Whether you need a point-in-time penetration test or an ongoing vulnerability management program, Stone-Knight delivers findings that are clear, actionable, and tied directly to business risk — not just a list of CVEs.
What you get:
- Detailed findings with severity ratings and remediation guidance
- Executive summary for leadership and technical detail for your security team
- Post-assessment support to verify remediation was effective
- A partner who stays engaged beyond the report
our story & team
We built Stone-Knight the way we believe security should be practiced — with honesty, accountability, and a genuine partnership with every client we take on.
Stone-Knight Security was built on a simple premise: most organizations don't know what they don't know. Threat actors count on that gap. We close it. Founded by security practitioners with hands-on experience across federal, defense, and commercial sectors, Stone-Knight brings a mission-driven mindset to every engagement. Our backgrounds span offensive security operations, compliance and risk management, cloud architecture, and incident response — giving our clients a team that has seen attacks from both sides of the wire.
We don't staff engagements with junior analysts chasing certifications. Every Stone-Knight consultant brings verified technical depth, relevant industry credentials, and a track record of delivering results under pressure. Our team holds certifications including CISSP, CEH, OSCP, and others aligned to the specific disciplines we practice.
What sets us apart isn't just what we find — it's how we communicate it. We translate complex technical risk into business language that executives can act on and security teams can execute against. That commitment to clarity and follow-through is what keeps our clients coming back.
Our engagements are built on three principles:
- Integrity — We tell you what we find, not what you want to hear
- Partnership — We stay engaged beyond the report until risk is resolved
- Precision — Every finding is scoped, validated, and tied to real-world impact
