Real-World Impact: Our Success Stories
Securing a Payment Gateway for PCI-DSS Level 1 Compliance
Industry: FinTech
Client Overview: A fast-growing payment processing startup was preparing for its mandatory PCI-DSS Level 1 audit. A failure would mean losing key partnerships and halting their growth. They needed an external partner to rigorously test their systems and ensure they were prepared for the official audit.
Key Challenges:
- Handling sensitive cardholder data across multiple microservices.
- Ensuring end-to-end encryption was properly implemented.
- Identifying any potential vulnerabilities that could lead to an audit failure.
- Meeting a tight deadline before the scheduled audit.
Our Solution:
We conducted a comprehensive white-box penetration test and code audit focused specifically on PCI-DSS requirements. Our team meticulously reviewed their data flow, encryption libraries, API security, and logging mechanisms.
- Identified three critical vulnerabilities, including an encryption key management flaw.
- Pinpointed insecure data logging practices that were storing sensitive information.
- Provided a detailed, prioritized remediation plan with code-level examples.
- Delivered a comprehensive report that served as a pre-audit checklist for their team.
"Developers.dev was instrumental in our successful PCI audit. Their report was clear, actionable, and gave our team the confidence we needed. They found things our internal team had missed for months."
Tripling User Capacity for a Mid-Market SaaS Platform
Industry: SaaS (Software as a Service)
Client Overview: A B2B SaaS company with a growing user base was experiencing frequent slowdowns and outages during peak hours. Their inability to scale was causing customer churn and threatening a major enterprise contract. They suspected deep-rooted architectural issues but couldn't pinpoint the source.
Key Challenges:
- Diagnosing intermittent performance bottlenecks in a complex legacy codebase.
- Scaling the database to handle a rapidly increasing load.
- Improving application response times without a complete rewrite.
- Minimizing downtime during the implementation of fixes.
Our Solution:
Our team performed a full architectural and performance audit. This involved code profiling, database query analysis, and load testing to simulate peak traffic. We identified several critical bottlenecks in their data access layer and caching strategy.
- Discovered N+1 query problems causing thousands of unnecessary database calls.
- Identified an inefficient caching strategy that was invalidating too frequently.
- Recommended a move to a read-replica database model to offload reporting queries.
- Provided refactoring guidance for key services to improve concurrency.
"The performance audit was a game-changer. The Developers.dev team didn't just find problems; they gave us a practical roadmap to fix them. Our platform is faster and more stable than ever."
Ensuring HIPAA Compliance for a Telemedicine Platform
Industry: Healthcare Technology
Client Overview: A health-tech innovator developed a new telemedicine platform but needed to ensure it was fully HIPAA compliant before launching to a major hospital network. A breach involving Protected Health Information (PHI) would be catastrophic, leading to massive fines and irreparable damage to their reputation.
Key Challenges:
- Ensuring all PHI was encrypted at rest and in transit.
- Implementing robust access controls and audit trails.
- Securely handling data from third-party medical devices.
- Providing documentation to satisfy the hospital's stringent security review.
Our Solution:
We conducted a HIPAA-focused code and cloud configuration audit. Our healthcare compliance experts reviewed every aspect of their platform where PHI was stored, processed, or transmitted, cross-referencing against HIPAA's technical safeguards.
- Uncovered improper PHI handling in application logs.
- Identified weak access control policies in their AWS environment.
- Recommended stronger encryption ciphers for data in transit.
- Produced a detailed compliance report that they submitted to the hospital network, which was a key factor in closing the deal.
"Passing the hospital's security review was make-or-break for us. The HIPAA audit from Developers.dev was incredibly thorough and gave us the proof of compliance we needed to close our biggest deal yet."

Frequently Asked Questions
The duration depends on the size and complexity of the codebase. A small application might take 1-2 weeks, while a large, complex enterprise system could take 4-6 weeks. We provide a precise timeline after the initial scoping call.
You receive a comprehensive PDF report containing an executive summary for non-technical stakeholders, a detailed breakdown of each finding with risk scores, evidence (e.g., screenshots, code snippets), and a prioritized, actionable remediation plan for your development team.
Our primary service is to audit and report, maintaining a clear separation of duties. However, we can provide remediation support through a separate staff augmentation engagement, where our expert developers can work alongside your team to implement the fixes.
Protecting your IP is our top priority. We execute a strong NDA before any code is shared. All analysis is performed in a secure, isolated environment by our full-time, vetted employees, governed by our SOC 2 and ISO 27001 certified security protocols.
Pricing is based on the scope, including the size of the application (lines of code, number of components), the depth of the audit required, and any specific compliance needs. We provide a detailed, fixed-price quote after our free initial consultation and scoping session.
For a code audit (white-box), we typically need read-only access to your source code repository (e.g., GitHub, GitLab). For penetration testing, the access level depends on the methodology (from zero knowledge for black-box to full access for white-box). All access is temporary and conducted via secure channels.
