Why custom tooling
Off-the-shelf security tools are designed for generic environments. They detect known CVEs and common misconfigurations, but they miss the vulnerabilities that matter most: the business logic flaws in your payment processing flow, the authentication bypasses specific to your mobile banking implementation, the data exposure paths unique to your API architecture.
Custom security tooling is built around your specific technology stack, your deployment pipeline, and your compliance requirements. Instead of drowning in false positives from generic scanners, your team gets actionable findings tuned to your environment. Build once, run continuously, and catch the issues that off-the-shelf tools will never find.
Every tooling engagement is built in-house, backed by recognised offensive-security methodology and hands-on open-source contributions: a BlackHat Europe Arsenal tooling contribution, plus Google Summer of Code and Honeynet Project work. Offensive security practice and software engineering meet in the same hands, which is why the tools are reliable, maintainable, and tuned to how real attackers work. For organisations that also need ongoing review, we recommend combining custom tooling with our managed security retainer.
How a custom tooling engagement works
Every engagement follows a structured methodology. We build tools that your team can own and operate.
Requirements discovery
We map your technology stack, CI/CD pipeline, security pain points, and compliance requirements. You tell us what you need secured; we design the tooling.
Architecture design
Technical design document covering tool architecture, integration points, data flows, and deployment strategy. You approve before we write a line of code.
Development
Iterative development with regular demos. We build in sprints so you can provide feedback early and often, not just at the end.
Testing
Full testing against your environment. We validate detection accuracy, false positive rates, performance impact, and integration stability.
Deployment
Production deployment with documentation, runbooks, and training for your team. We ensure your engineers can operate and extend the tools independently.
Support and iteration
Ongoing maintenance and iteration. Security threats evolve and your tools need to evolve with them. We provide support agreements tailored to your needs.
Who this is for
Custom security tooling is for organisations that have outgrown off-the-shelf scanners and commodity SAST/DAST tools, and need tools that match their specific environment and workflows.
- Banks and BNR-supervised enterprises: commercial banks, microfinance institutions, and payment service providers needing automated security testing tailored to financial applications
- Government and ministries: public-sector bodies needing automated security testing baked into citizen-facing systems and critical infrastructure
- Telecoms and mobile money operators: organisations handling millions of transactions daily that need recurring automated security validation
- Healthcare and insurance: hospitals and insurers managing sensitive patient and policyholder data needing automated security checks integrated into their development workflow
- Fintechs and development teams: fast-moving companies that need security baked into their CI/CD pipeline without slowing down releases
- DevSecOps teams: internal security teams that need custom tooling to scale their security testing across multiple applications and environments
Compliance alignment
Custom security tooling helps organisations meet ongoing compliance requirements through automation. The tools we build map directly to regulatory frameworks:
- BNR Regulation N°50/2022 on cyber security: requires supervised institutions to conduct regular security testing. Custom CI/CD security tools automate this requirement, ensuring every code change is tested before deployment
- PCI DSS v4.0: Requirement 6.2 requires secure development practices and software security testing throughout the development lifecycle. SAST/DAST pipeline integration enforces this requirement automatically on every build
- ISO 27001:2022: Annex A Control 8.25 (Secure development lifecycle) requires security to be embedded throughout the development process. Custom pipeline tools make this requirement operational rather than aspirational
- Rwanda Data Protection Law No 058/2021: Article 47 requires data controllers and processors to adopt appropriate technical measures to ensure the security of personal data. Automated security testing and compliance reporting tools provide continuous evidence of compliance
The compliance reporting tools we build for clients generate audit-ready evidence mapped to these frameworks. For more on BNR requirements, see our guide on BNR cybersecurity requirements for banks in Rwanda. You may also find our article on API security for banking relevant if your tooling needs involve API protection.
