Penetration testing, compliance and incident response
Security that holds up when someone tests it.
Silver Fox is a Texas cybersecurity firm. We test applications and networks the way attackers do, prepare companies for CMMC, SOC 2 and ISO 27001, and help security teams detect and respond to real attacks.

Why Silver Fox
Most breaches start with something ordinary.
A contractor's VPN account without MFA. A storage bucket left open after a migration. An old test server that still answers on the internet.
Attackers chain small problems like these into big ones. We look at your environment the same way, help you close the paths that lead somewhere important, and give you the evidence to show customers, auditors and your board that you did.
Offensive insight
Our testers think like attackers, so findings reflect what could actually happen to you.
Defensive discipline
Monitoring and response built around decisions, with less noise for your team to wade through.
Engineering depth
When we find a problem, we can stay and help your team fix it properly.
What we do
Six practices that work as one team.
Each practice stands on its own, and each one makes the others better. Penetration test findings shape detection rules. Incidents feed the risk register. Compliance work fixes real gaps.
- 01
Cyber Strategy, Risk & Compliance
Risk assessments, virtual CISO leadership and compliance readiness that hold up under scrutiny.
- Risk assessments and security roadmaps
- Virtual and fractional CISO services
- Readiness for CMMC, SOC 2, HIPAA and more
- 02
Penetration Testing & Offensive Security
Penetration testing, red teaming and adversary simulation that show what an attacker could actually reach.
- Web, API and mobile application testing
- Internal, external and cloud penetration tests
- Red team, purple team and assumed breach exercises
- 03
Cloud, Application & Infrastructure Security
Secure architecture and hands-on engineering for cloud platforms, applications, networks and endpoints.
- AWS, Azure and Google Cloud security reviews
- DevSecOps and CI/CD pipeline hardening
- Zero Trust and network segmentation
- 04
Identity & Data Security
Protect identities, privileged access and the sensitive data they can reach.
- Microsoft Entra ID and Active Directory security
- Privileged access management
- Data discovery, classification and DLP
- 05
Managed Detection & Response
Security monitoring, detection engineering and threat hunting focused on real threats rather than alert volume.
- Managed detection and response (MDR)
- SOC design, SIEM and detection engineering
- Threat hunting and security automation
- 06
Incident Response & Digital Forensics
Contain active incidents, find out what happened and recover with evidence you can stand behind.
- Ransomware and business email compromise response
- Digital forensics and compromise assessments
- Incident response retainers and threat intelligence
How attacks unfold
Every intrusion is a chain. Each link is a chance to stop it.
Here is a pattern that shows up again and again in real incidents, with the practice that breaks the chain at each step.
- 01
Initial access
A reused password works on an internet-facing VPN portal that nobody remembered to put behind MFA.
Penetration testing and SCOPE - 02
Credential theft
From the first laptop, the attacker collects cached credentials, including a help desk account.
Identity and privileged access - 03
Lateral movement
A flat network lets them reach file servers and, eventually, a domain controller.
Architecture and segmentation - 04
Detection window
New admin accounts and unusual sign-ins raise alerts. Someone has to notice them in time.
Managed detection and response - 05
Impact
Data is copied out and ransomware is staged to run late on a Friday night.
Incident response and forensics
Compliance readiness
18 frameworks, one program behind them.
We prepare you for audits and third-party assessments, close the gaps an assessor would find and keep your evidence current afterward.
ISO & IEC
International management system, cloud and industrial standards, certified by accredited bodies.
More on ISO & IECNIST
US government frameworks and special publications used by agencies, contractors and the private sector.
More on NISTSOC
AICPA attestation reports issued by licensed CPA firms for service organizations.
More on SOCUS & industry
Federal, state and industry requirements tied to contracts, data types and payments.
More on US & industry
Certifications and attestation reports are issued by accredited third parties. We get you ready and work alongside your assessor.
Industries
Focused on the industries that keep Texas running.
Energy, healthcare, defense, finance, technology and government each carry their own threats, regulators and constraints. We plan our work around them.
Defense & Aerospace
CMMC readiness, CUI protection and security testing for primes and subcontractors in the defense industrial base.
