Source Code Security Review

Find vulnerabilities at the source. Our experts combine static analysis with line-by-line manual review of your most critical code to catch flaws testing alone can miss.

Attack path focus LIVE

  • Manual review of critical paths
  • SAST with triage
  • Secrets & dependency checks
  • Developer-ready fixes

Overview

US enterprise and public-sector buyers increasingly ask software vendors how they build securely, often with reference to the NIST Secure Software Development Framework (SP 800-218). A source code review shows that security is part of your development process, and it finds flaws such as broken authorization or unsafe deserialization that black-box testing can miss.

Some vulnerabilities are far easier to find in code than from the outside: subtle authorization checks, insecure cryptography, unsafe deserialization, hidden debug functionality or hard-coded secrets. A source code security review examines how your application really works.

We combine static application security testing (SAST) with focused manual review of the code that matters most — authentication, authorization, payment and data-handling logic, input processing and integrations. Tool findings are triaged by experts so your developers see real issues, not thousands of warnings.

Code review pairs especially well with a web or API penetration test (white-box testing), giving the highest assurance for critical applications.

How testing works for US organizations

  • Signed scope and written authorization before any testing, including hosting and cloud provider permissions
  • Testing windows agreed around your US time zone at scoping, including after-hours windows for production
  • Fully remote delivery, with internal and wireless access via VPN or a shipped test device, so no travel costs
  • Reports mapped to SOC 2, PCI DSS, HIPAA and customer questionnaires, with a fixed price in USD

What's included

Our approach

  1. Threat modelIdentify critical components and data flows.
  2. Automated analysisSAST, secrets and dependency scanning.
  3. Manual reviewExpert line-by-line review of high-risk code.
  4. ValidateConfirm exploitability and impact where possible.
  5. Report & walkthroughFindings with code references and fixes.

Frequently asked questions

Which languages do you review?

Common languages including Java, C#, JavaScript/TypeScript, Python, PHP, Go, Kotlin and Swift. Confirm specific frameworks during scoping.

Do you need access to our full repository?

We need the code in scope and enough context to build or understand it. Access can be provided through a secure, time-limited method.

Is our code kept confidential?

Yes. Code is handled under NDA, stored encrypted and securely deleted after the engagement.

Are you a PCI QSA or ASV, FedRAMP 3PAO or CMMC C3PAO?

No. We don't claim any of those statuses on this site. Most penetration tests for SOC 2, HIPAA, PCI DSS Requirement 11.4, the FTC Safeguards Rule and customer due diligence don't require them. If your contract, assessor or program requires a specific accredited provider, tell us at scoping and we'll say plainly whether we can meet it. See US compliance requirements.

Do you quote in US dollars?

Yes. US proposals are fixed-price and quoted in USD, with scope, effort, deliverables and payment terms set out in writing before work starts. See our US pricing guide for published market ranges.
