Security & testing built
into every system.
We identify vulnerabilities, enforce secure coding practices, and ensure your systems meet industry-grade security standards — before attackers get the chance.
How we think
Security philosophy.
Aligned with OWASP principles and real-world attacker mindsets. These aren't aspirations — they're constraints we build within.
Security by Design
Security isn't a layer added at the end — it's woven into architecture decisions, data flows, and system boundaries from day one.
Defense in Depth
We apply multiple layers of security controls so that if one layer fails, others prevent a breach. No single point of failure.
Zero-Trust Mindset
Never trust, always verify. Every request is authenticated and authorised — inside or outside the network perimeter.
Continuous Testing
Security testing isn't a one-time audit. We integrate checks into CI/CD pipelines so every deployment is verified automatically.
What we do
Core security services.
Five service lines covering every attack surface — from your application code to your cloud infrastructure.
Application Security Testing (AST)
Comprehensive analysis of your application code and runtime behaviour — before attackers find the gaps.
- ▸Static Analysis (SAST) — code-level vulnerability detection
- ▸Dynamic Analysis (DAST) — runtime attack simulation
- ▸Software Composition Analysis (SCA) — third-party dependency audits
- ▸Secure code review with developer-level recommendations
Penetration Testing
Controlled, ethical exploitation of your systems using real-world attacker techniques and industry-standard frameworks.
- ▸Web application penetration testing
- ▸API endpoint attack simulation
- ▸Authentication & session management testing
- ▸Business logic flaw exploitation (controlled)
API Security Testing
APIs are the most targeted attack surface in modern systems. We test every endpoint, auth flow, and data boundary.
- ▸Authentication & authorisation flaws
- ▸Broken Object Level Authorisation (BOLA)
- ▸Rate limiting & abuse protection gaps
- ▸Sensitive data exposure via API responses
Infrastructure Security
Hardened servers, locked-down cloud configs, and network-level reviews that close the gaps attackers exploit first.
- ▸Server hardening & baseline configuration
- ▸Cloud misconfiguration checks (AWS, GCP, Vercel)
- ▸Network security & firewall rule reviews
- ▸Container and Docker security scanning
Compliance & Risk Assessment
Structured audits aligned to regulatory requirements — including Kenya's eTIMS/VSCU compliance and data protection standards.
- ▸eTIMS & VSCU compliance validation
- ▸Data protection risk scoring
- ▸Security audit reports with risk classification
- ▸Remediation roadmaps prioritised by severity
Industry standard coverage
OWASP Top 10 coverage.
We test against every vulnerability category defined by the Open Web Application Security Project — the global standard for web security. Click any item to explore what we test for.
Broken Access Control
Restrictions on what authenticated users can do are not properly enforced — allowing privilege escalation and data access.
How we work
Testing methodology.
A structured, repeatable process — not ad-hoc scanning. Every engagement follows the same rigorous pipeline.
Reconnaissance
Map the attack surface — endpoints, tech stack, exposed services, and entry points.
Vulnerability Scanning
Automated and manual scanning for known CVEs, misconfigurations, and security gaps.
Controlled Exploitation
Ethical exploitation of discovered vulnerabilities to confirm real-world impact.
Risk Analysis
Classify every finding by severity — Critical, High, Medium, Low — with business impact context.
Remediation Guidance
Detailed fix recommendations per vulnerability — not just what's wrong, but how to fix it.
Retesting & Sign-off
Re-test every remediated vulnerability and issue a formal security clearance report.
Our arsenal
Tools & technologies.
We leverage industry-standard tools and custom methodologies — choosing the right instrument for each engagement rather than relying on any single platform.
Burp Suite
Industry-standard web vulnerability scanner and intercepting proxy
OWASP ZAP
Open-source dynamic application security testing tool
Metasploit
Framework for developing and executing exploit code
Nmap
Network discovery and security auditing utility
Nikto
Web server scanner for dangerous files and misconfigurations
SQLMap
Automated SQL injection detection and exploitation tool
Trivy
Comprehensive vulnerability scanner for containers and dependencies
Custom Scripts
Purpose-built tools tailored to your specific system architecture
Tools amplify methodology, not replace it. Our engineers understand the underlying vulnerabilities — not just how to run a scanner. Custom scripts and manual testing are integral to every engagement.
What you receive
Reporting & deliverables.
Every engagement ends with a structured report — not a raw scanner dump. You get context, classification, and a clear path to resolution.
Risk Severity Classification
Critical
Immediate exploitation risk — remediate within 24 hours
High
Significant risk — remediate within 7 days
Medium
Moderate risk — remediate within 30 days
Low
Minor risk or informational — address in next sprint
Report Deliverables
Executive Summary
A non-technical overview of security posture, key findings, and business risk
Vulnerability Report
Detailed per-vulnerability writeups with CVE references, proof-of-concept, and impact analysis
Risk Matrix
Visual risk register mapping every finding by severity and exploitability
Remediation Playbook
Step-by-step fix instructions per vulnerability — code examples where applicable
Retest Certificate
Formal confirmation that all critical and high findings have been resolved and verified
Built-in, not bolted-on
Security in the development lifecycle.
The biggest security risk is treating it as an afterthought. We embed security into every stage of development — not just at launch.
Secure Coding Practices
Our engineers follow OWASP Secure Coding Guidelines on every project — input validation, output encoding, parameterised queries, and least-privilege by default.
CI/CD Security Checks
Security scanning is integrated into our deployment pipelines. Dependency audits, SAST scans, and container vulnerability checks run on every commit.
Continuous Monitoring
Post-deployment, we configure real-time alerts for anomalous behaviour — failed auth attempts, unusual data access patterns, and error rate spikes.
Periodic Retesting
Security posture degrades over time. We offer scheduled quarterly or biannual retests to catch new vulnerabilities introduced by feature changes.
"If we build with Tech-Stun, we don't need another security team."
We build + secure + certify readiness. Your POS, AI system, SaaS, and APIs are delivered production-hardened — not just functional.
Real findings
Security case studies.
Real vulnerabilities found in real systems. Names redacted, details preserved. This is what we find — and fix.
Critical Auth Bypass in POS API
Scenario
A multi-branch POS system with a public-facing management API. Security audit requested before enterprise rollout.
Finding
Discovered a broken object-level authorisation flaw — any authenticated user could access and modify other branches' transaction data by changing a single API parameter.
Outcome
Vulnerability patched before launch. Prevented potential exposure of KES 50M+ in transaction data across all branches.
SQL Injection in Pharmacy System
Scenario
Legacy pharmacy POS with an integrated supplier ordering module. Routine security review before eTIMS integration.
Finding
Found an unsanitised input field in the supplier search endpoint that was vulnerable to SQL injection — allowing full database read access.
Outcome
Input sanitisation and parameterised queries implemented. Database access controls hardened. Full eTIMS audit trail secured.
JWT Secret Key Exposure in SaaS Platform
Scenario
Early-stage SaaS platform with multi-tenant architecture undergoing pre-launch security hardening.
Finding
Hardcoded JWT signing secret found in the codebase — any attacker with repo access could forge authentication tokens for any tenant.
Outcome
Secret rotated, moved to environment-based secrets management, and short-lived token policy enforced. Zero-trust auth redesigned.
