What Our Clients Say

Sheepdog Cyber Defense works with Texas businesses of all sizes to identify vulnerabilities and build stronger security programs. Here's what our clients have to say about the impact we've made.

"We were planning to do penetration testing 'someday' but didn't know where to start. Sheepdog made the process straightforward and the report was actually understandable. Our team felt confident implementing their recommendations."

— IT Director, San Antonio Tech Company

"The findings weren't just a list of vulnerabilities with technical jargon. They explained what each issue meant for our business and gave us clear steps to fix them. Worth every penny."

— Operations Manager, Spring Branch Manufacturing

"Red teaming felt intimidating at first, but it was the validation we needed to show our board that our security investments were working. The team was professional and the debrief was incredibly valuable."

— CISO, San Antonio Financial Services

"Working with a local firm made a huge difference. We could actually sit down and talk through the findings, not just get a PDF report and figure it out ourselves."

— CEO, Bulverde Professional Services Firm

How We've Helped

External Testing Prevented Ransomware Attack

Client: Mid-sized San Antonio IT Services Company

Challenge: Company had never undergone penetration testing and wasn't sure about their internet-facing security

What We Did: Conducted comprehensive external penetration testing of their entire attack surface. Found an exposed RDP service with weak credentials and an unpatched critical vulnerability in their public-facing web server.

Impact: Client patched the vulnerabilities immediately. Three months later, a ransomware variant that exploited that exact vulnerability affected competitors in the same industry. Because of the penetration test and remediation, this client was protected.

Key Takeaway: Penetration testing isn't about compliance—it's about prevention. Finding vulnerabilities before attackers do is the real value.

Red Teaming Exposed Incident Response Gaps

Client: Healthcare Organization in the Texas Hill Country

Challenge: Had good security tools but wanted to test whether the team could actually detect and respond to an attack

What We Did: Conducted a four-week red teaming engagement simulating an attacker trying to access patient data. The red team gained access to the network, moved laterally, and attempted to reach the database.

Impact: Security team detected the attack after 11 days (better than the 2-week industry average). However, incident response procedures were unclear, and the team didn't know who to contact or what steps to take. Based on our findings, they completely rewrote their incident response playbooks and added specific detection triggers for common attack patterns.

Key Takeaway: Having security tools isn't enough—your team needs to know what to do when an attack happens. Red teaming validates your entire program, not just your systems.

Compliance-Driven Testing Led to Better Security

Client: Small E-Commerce Business in Spring Branch

Challenge: Required to do penetration testing for PCI-DSS compliance but viewed it as a checkbox

What We Did: Beyond the required PCI testing, we also assessed their internal network and administrative access controls. Found that employees had excessive permissions and that the backup system lacked proper access restrictions.

Impact: After remediation, the client had stronger compliance evidence for audits, but more importantly, they reduced insider risk significantly. They also discovered their backups weren't being properly monitored for ransomware encryption.

Key Takeaway: Compliance testing can be the starting point for a better security program. The best organizations use compliance requirements as leverage to fund real security improvements.

Web Application Testing Prevented Data Exposure

Client: SaaS Company Based in San Antonio

Challenge: Had just launched a new customer portal and wanted to ensure it was secure before going live

What We Did: Comprehensive web application penetration testing found three vulnerabilities: an insecure direct object reference (IDOR) vulnerability allowing customers to access other customers' data, improper input validation, and a SQL injection risk in the search function.

Impact: All three vulnerabilities were patched before launch. The company avoided a potential data exposure incident that could have cost them customers and regulatory fines. The portal launched on schedule and securely.

Key Takeaway: Testing before launch is significantly cheaper and easier than fixing issues after customers discover them. Pre-launch security testing is essential for any new application.
