Protect Your Business Before Attackers Find the Weaknesses
Security isn’t a checkbox—it’s a mindset. At REPTILE.HAUS, we’ve been finding and fixing vulnerabilities for over 15 years, starting from our founder’s early days of responsible disclosure that earned trust by helping businesses before they got burned.
We conduct penetration testing, security audits, and compliance consulting that goes beyond automated scans. We think like attackers to find the real weaknesses—the ones that actually get exploited, not just the theoretical risks.
Whether you need a pre-launch security assessment, ongoing penetration testing, or help meeting GDPR, PCI-DSS, or SOC 2 requirements, we bring battle-tested expertise to protect what you’ve built.
Why Choose REPTILE.HAUS for Security
We’ve been finding vulnerabilities for over 15 years—from our founder’s responsible disclosure beginnings to collaborating with Berlin’s renowned Cure53 on sensitive human rights applications. What makes us different:
- Hacker mindset, business focus – We think like attackers but advise like partners. We find real vulnerabilities that could actually be exploited, not just theoretical issues that pad a report.
- 15+ years of security experience – From early ethical hacking to professional penetration testing, our security expertise has evolved with the threat landscape. We’ve seen it all.
- Cure53 collaboration – We’ve worked alongside Berlin’s renowned security firm on sensitive application analysis for human rights organizations. We operate at the highest levels.
- Full-stack security knowledge – We secure web apps, mobile apps, APIs, cloud infrastructure, and blockchain systems because we build them too. We understand how systems actually work.
- Clear, actionable reports – No 100-page documents full of jargon. We deliver prioritized findings with practical remediation steps your team can actually implement.
The result: Security assessments that actually improve your security posture—not just compliance theater.
Who We Work With
We’re the ideal fit if you:
- Handle sensitive data (customer PII, financial records, health information)
- Need to meet compliance requirements (GDPR, PCI-DSS, SOC 2, ISO 27001)
- Are preparing for an acquisition, funding round, or enterprise client requirements
- Have experienced a security incident and need to prevent recurrence
- Want proactive security assessment before launching new products
Our sweet spot: Organizations who understand that a breach costs far more than prevention—whether that’s regulatory fines, reputational damage, or operational disruption.
Let's get started
Capabilities
Our security services cover the full attack surface:
- Web application penetration testing – Manual testing that goes beyond automated scans. We find the vulnerabilities that OWASP ZAP and Burp Suite miss.
- Mobile app security assessment – iOS and Android application testing including reverse engineering, API analysis, and data storage review.
- API security testing – Authentication bypass, authorization flaws, injection attacks, and business logic vulnerabilities in your APIs.
- Cloud security review – AWS, GCP, and Azure configuration assessment. IAM policies, network security, and infrastructure hardening.
- Smart contract audits – Security review of Solidity and blockchain smart contracts before deployment. Reentrancy, access control, and economic exploits.
- Code review & security architecture – Source code analysis and security architecture review. We find vulnerabilities at the design level.
- Compliance consulting – GDPR, PCI-DSS, SOC 2, ISO 27001 readiness assessments and remediation guidance.
Common Security Challenges We Solve
Many organisations struggle with:
- Not knowing what they don’t know about their security posture
- Previous audits that were just checkbox exercises with no real improvement
- Security reports full of jargon that developers can’t action
- Needing security validation for investors or enterprise clients
- Launching new technology without confidence it’s secure
Security shouldn’t be an afterthought or a compliance burden.
We find real vulnerabilities and give you practical remediation steps—so you can fix issues before attackers find them.
Our approach
02. Reconnaissance & Testing
We map your attack surface and conduct thorough testing using manual techniques and specialised tools. We simulate real attacker behaviour to find vulnerabilities before they do.
03. Analysis & Reporting
We document findings with clear severity ratings, evidence, and actionable remediation guidance. Each vulnerability includes proof-of-concept and step-by-step fix instructions.
04. Verification & Support
After you’ve fixed issues, we re-test to confirm vulnerabilities are properly remediated. We remain available for questions and can provide ongoing security advisory.
What We Deliver
Typical outcomes from our security assessments:
- Clear security posture – Know exactly where your vulnerabilities are and how serious they are
- Prioritised remediation – Focus on fixing the issues that actually matter first
- Compliance confidence – Documentation and evidence for regulatory requirements
- Reduced risk – Address vulnerabilities before attackers can exploit them
- Developer education – Your team learns secure coding practices through our findings
Case Studies
Human Rights Watchdog App Analysis
Joined Berlin-based security firm Cure53 on secondment to conduct comprehensive security analysis of a mobile application used by human rights activists and journalists in high-risk environments.
Scope:
- Reverse engineering of mobile applications
- Protocol analysis and traffic inspection
- Cryptographic implementation review
- Threat modeling for targeted attack scenarios
- Privacy and anonymity assessment
The application continues to protect journalists and activists documenting human rights abuses. Read the full case study →
15+ Years of Security Origins
REPTILE.HAUS was founded on security expertise. Our founder Paddy O’Sullivan began by identifying vulnerabilities in websites and responsibly disclosing them to owners—often resulting in those businesses becoming our first clients.
Core principles:
- Attacker perspective – understanding how real adversaries think
- Responsible practice – testing with clear scope and ethical boundaries
- Practical focus – finding issues that actually matter
- Business context – recommendations that work within real constraints
- Continuous learning – staying at the forefront as threats evolve
Today, we apply this deep security foundation across all our development work—building secure systems from the start.
Let's Secure Your Business
Security isn’t a one-time checkbox—it’s an ongoing practice. A breach costs far more than prevention: regulatory fines, reputational damage, and operational disruption.
Get in touch and let’s assess your security posture before attackers do.
