Security

Find the gaps. Then close them.

Stahl runs a security practice designed to pair with an infrastructure team. We don't just hand you a report — we remediate what we find, under one contract, with one point of accountability. Technical delivery is executed through a vetted partner network of specialist operators, coordinated and interpreted by Stahl.

The Stahl difference

Most firms stop at the report. We don't.

Standalone pen-testing firms can only hand you a PDF. Network installers don't understand adversarial security. Because Stahl does both, our security engagements close the loop — the same team that finds the gap can fix it.

01

Test

We identify what's exposed — through point-in-time pen testing, continuous assessment, or adversary simulation.

02

Translate

Raw findings become prioritized, plain-language guidance your executives and your auditors can both act on.

03

Remediate

Our networking practice closes the gaps — one contract, one team, no finger-pointing between vendors.

Capabilities

Every surface an adversary can reach. Tested, translated, and closed.

Six engagement types, matched to how sophisticated organizations actually consume security — from the annual test a regulator demands, to the continuous assurance a listed company requires, to the confidential audit a principal quietly commissions.

Offensive testing$10,000 – $45,000 / engagement

Vulnerability Assessment & Penetration Testing

Scoped adversarial testing across every surface the attacker can reach. Delivered point-in-time for audit cycles, or continuously for operations that can't wait a year between tests.

Methodology

Published standards. Not private frameworks.

Every Stahl engagement is mapped to industry-recognized testing and control standards. Your auditor has heard of them. Your counsel has read them. And when a finding is disputed, the reference is already on the page.

Private Client & Family Offices

Security at the scale your family actually operates.

43% of family offices experienced a cyberattack in 2024 — but only 40% have adequate controls. We close that gap without making your household feel like an IT department, and without the name of your principal ever touching a vendor datasheet.

  • Principal & family-member threat model
  • Device, identity, and OSINT hardening
  • Annual VAPT of residential networks
  • Quiet, confidential engagement posture
Corporate & Regulated

Programmatic security that meets regulators where they are.

For listed, regulated, or pre-transaction organizations, assessment isn't optional — but it's often performative. We deliver assessments that change the underlying risk posture, not just the checkbox, mapped to SOC 2, ISO 27001, PCI DSS, HIPAA, and NIST CSF as applicable.

  • Annual external + internal VAPT cycle
  • Board-ready risk & program reporting
  • Vendor & third-party risk review
  • vCISO retainer for continuous oversight

Know what you're actually exposed to.

Start with a scoped assessment. We'll tell you what to fix first — and, if you want, we'll fix it.
