Secure Code Review (SCR)

NetSPI » Security Assessments » Secure Code Review

Identify and eliminate application security risk at the source before it reaches production, your customers, or your acquirers.

 

Our Approach to Secure Code Review

Every engagement combines automated analysis with deep-dive manual review by our security engineers, a human-in-the-loop methodology calibrated to the scope, codebase, and risk profile of each engagement. Reviews are anchored on a threat model pertaining to the application. Across every engagement, reviewers focus on critical functions including:

  • Authentication / Authorization
  • Cryptography
  • Deserialization
  • Injection Sinks
  • Business Logic
  • Trust Boundaries

We deliver findings with reproducible evidence, exploitability context, and remediation guidance developers can act on.

Code with Confidence

NetSPI secure code review solutions cover the vast majority of modern languages and frameworks. Common ones include ( but are not limited to ) Java, .NET, JavaScript, TypeScript, Python, Go, Rust, C / C++, PHP, and IaC. Our code review experts also have extensive experience working with less popular languages, and do so regularly based on engagement needs.

Secure Code Review Offerings

Insecure code introduces risk across the entire software lifecycle: in the application itself, in the dependencies it inherits, in the supply chain it ships through, and in the people who build and maintain it. Our secure code review offerings address each of these surfaces.

  • Application Secure Code
  • Vulnerability Triage
  • Malicious Code Detection

  • Supply Chain
  • M&A Code

Application Secure Code Review The most common entry point for new clients

Reviewers conduct an end-to-end review of your application’s source code, supported by automated analysis across SAST, SCA, secret detection, and infrastructure-as-code.

  • Every finding is validated against the surrounding code and data flow before it reaches your developers – no raw tool output, no false-positive triage left on your team.
  • Findings ship with reproducible evidence, exploitability context, and actionable remediation guidance.

Vulnerability Triage Secure Code Review

Modern security tooling generates more findings than your team can act on and AI-assisted development tools ( Cursor, Claude, vibe-coding platforms) are now producing raw code at a pace traditional scanners weren’t built for.

  • Our reviewers ingest findings from your existing SAST, SCA, secret scanners, and AI code review tools, validate each against the surrounding code and data flow, eliminate false positives, and rank the remainder by real exploitability and business impact. Your developers get a short, prioritized list of confirmed issues with evidence and detailed solution guidance.

Supply Chain Security Assessment

Vulnerability scanners tell you which dependencies have known CVEs. Supply chain security asks a bigger question. Can you trust the chain of code, contributors, and infrastructure putting those dependencies into your application?

  • Incidents like Log4Shell and MOVEit targeted that chain and AI coding assistants are now pulling in packages developers never vetted, accelerating the problem.
  • Our assessment goes beyond what tools see: SBOM accuracy validation, CI/CD pipeline review, provenance and typosquatting checks, maintainer and upstream trust analysis, and inspection of vendored dependencies and build scripts that automated scanners routinely miss.

Malicious Code Detection (MCD)

Backdoors, logic bombs, hard-coded exfiltration paths, unauthorized data collection, and intentionally weakened security controls don’t show up in standard vulnerability reports, they’re written to evade them.

  • Targeted Review: Malicious Code Detection is a targeted review for adversarial code patterns introduced by insiders, departing developers, compromised contributors, or upstream supply chain attacks.
  • Common Situations: Post-acquisition diligence on an inherited codebase, contractor or departing developer offboarding, supply chain incident response, breach of trust events, and high-assurance review of code from third-party vendors.

M&A Code Due Diligence Merger & Acquisition

Code is one of the largest unmeasured risk and value drivers in a software acquisition.

  • Our M&A code due diligence service gives acquirers and investors a defensible view of what they’re actually buying – code security posture, malicious or suspicious code patterns, third-party dependency risk, secrets, and the engineering debt that will surface.
  • Engagements range from rapid pre-LOI assessments to deep post-LOI technical diligence. Deliverables are structured for deal teams, and findings are quantified by deal-blocking severity and integration risk, not just engineering impact.
