Schaefer Operations is an offensive security firm based in Texas. We run penetration tests and red team engagements for small and mid-sized businesses, testing your defenses the way real attackers would so you can fix what we find before someone else does.
Services
External penetration testing + OSINT
Web application penetration testing (apps, APIs and portals)
Internal penetration testing
Red team engagements
The Offensive Subscription: testing days every quarter for any mix of engagements, at one flat monthly rate on an annual contract
How an engagement works
Scoping call: we learn what you need tested and who is asking for it, then send you a quote.
Rules of engagement: we agree in writing on what is in scope, the testing dates and hours, and who to call if anything looks wrong.
Testing: real attacker techniques, safe for production. If we find something critical, we tell you right away.
Report and walkthrough: an executive summary, validated findings with proof-of-concept evidence, and clear remediation steps. Every report is peer reviewed before delivery, and we walk your team through the findings.
Why clients choose us
Every operator is a US citizen who has passed a background check. We never offshore or subcontract your engagement.
Our operators hold CRTO, CRTL, OSEP, OSCP, CAPE and CWEE certifications.
We sign a mutual NDA before you share any details, carry general and professional liability insurance, and complete vendor security questionnaires.
