Finding Vulnerabilities at the Source

Security vulnerabilities in application code can lead to serious breaches, data loss, and system compromise. Our Security Code Review service identifies these issues at their source—in the actual code—before they can be exploited in production environments.

Our expert security engineers combine automated tools with manual analysis to thoroughly examine your source code for security flaws, implementation errors, and deviations from secure coding best practices. We don't just find vulnerabilities; we provide detailed remediation guidance and work with your development team to implement secure coding practices.

Whether you're developing a new application, maintaining legacy code, or preparing for a security compliance audit, our code review services help ensure that security is built into your software from the ground up.

Common Vulnerabilities We Identify

Real-world security issues our code reviews frequently uncover.

High SQL Injection

// Vulnerable code
function getUserData(userId) {
  const query = "SELECT * FROM users WHERE id = '" + userId + "'";
  return db.execute(query);
}

// Secure code
function getUserData(userId) {
  const query = "SELECT * FROM users WHERE id = ?";
  return db.execute(query, [userId]);
}

SQL injection vulnerabilities occur when user input is directly incorporated into SQL queries without proper sanitization. This can allow attackers to manipulate queries and access, modify, or delete data they shouldn't have access to.

High Cross-Site Scripting (XSS)

// Vulnerable code
function displayUserComment(comment) {
  document.getElementById('comments').innerHTML += comment;
}

// Secure code
function displayUserComment(comment) {
  const text = document.createTextNode(comment);
  const div = document.createElement('div');
  div.appendChild(text);
  document.getElementById('comments').appendChild(div);
}

Cross-Site Scripting vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users. These scripts can steal sensitive information, hijack user sessions, or perform actions on behalf of the victim.

Medium Insecure Deserialization

// Vulnerable code
function loadUserPreferences(serializedData) {
  const userPrefs = JSON.parse(serializedData);
  return userPrefs;
}

// Secure code
function loadUserPreferences(serializedData) {
  try {
    const userPrefs = JSON.parse(serializedData);
    return validateUserPrefs(userPrefs);
  } catch (e) {
    return defaultPrefs;
  }
}

Insecure deserialization vulnerabilities occur when applications deserialize data from untrusted sources without proper validation. This can lead to remote code execution, denial of service attacks, or authentication bypasses.

Medium Broken Access Control

// Vulnerable code
function getUserDocument(docId) {
  return db.getDocument(docId);
}

// Secure code
function getUserDocument(docId, userId) {
  const doc = db.getDocument(docId);
  if (doc.ownerId !== userId && !isAdmin(userId)) {
    throw new AccessDeniedError();
  }
  return doc;
}

Broken access control vulnerabilities occur when applications fail to properly enforce restrictions on what authenticated users can do. This can allow attackers to access unauthorized functionality or data, such as viewing other users' records or performing privileged actions.

Code Review Success Story

See how our security code review services have made a real difference.

Financial Services API Platform: Critical Vulnerabilities Prevented

A leading financial technology company was preparing to launch a new API platform that would allow third-party developers to integrate with their payment processing services. Given the sensitive nature of financial data and the potential impact of security breaches, they engaged our team to conduct a comprehensive security code review before the platform's public release.

Key Findings:

  • Identified a critical authentication bypass vulnerability in the API token validation logic
  • Discovered multiple instances of SQL injection vulnerabilities in transaction processing endpoints
  • Found insecure cryptographic implementations that could potentially expose sensitive financial data
  • Detected several authorization flaws that could allow access to other customers' transaction records
  • Identified business logic vulnerabilities that could be exploited for financial fraud
  • Uncovered hardcoded credentials and API keys in the codebase

Our team worked closely with the client's development team to address these vulnerabilities before the platform's launch. We provided detailed remediation guidance, code examples, and conducted follow-up reviews to verify that the fixes were implemented correctly.

The client was able to launch their API platform on schedule with confidence in its security. The early detection of these vulnerabilities saved the company from potential data breaches, financial losses, and reputational damage that could have resulted if these issues had been discovered after deployment.

Frequently Asked Questions

Common questions about our security code review services.

How is a security code review different from regular code review?

While regular code reviews typically focus on code quality, maintainability, and functionality, security code reviews specifically target security vulnerabilities and weaknesses in the code. The key differences include:

  • Focus: Security code reviews specifically look for patterns and practices that could lead to security vulnerabilities, such as injection flaws, authentication weaknesses, and insecure data handling.
  • Expertise: Security code reviews are conducted by engineers with specialized knowledge of security vulnerabilities, attack vectors, and secure coding practices.
  • Tools: Security code reviews often employ specialized static analysis tools designed to detect security vulnerabilities that general code quality tools might miss.
  • Methodology: Security code reviews follow a systematic approach to identify different types of vulnerabilities, often guided by frameworks like OWASP Top 10 or SANS CWE Top 25.
  • Outcome: The primary outcome is identifying and addressing security risks, rather than improving code readability or performance.

Both types of reviews are valuable and complementary. While regular code reviews improve overall code quality, security code reviews provide the specialized focus needed to identify and address security-specific concerns.

When is the best time to conduct a security code review?

Security code reviews are valuable at multiple stages of the development lifecycle, but the optimal timing depends on your specific needs and development process:

  • During Development: Integrating security code reviews into your regular development process (e.g., as part of pull requests or sprint reviews) helps catch vulnerabilities early when they're easier and less expensive to fix.
  • Pre-Release: Conducting a comprehensive security code review before major releases provides an additional security check before code reaches production.
  • After Significant Changes: When making substantial architectural changes or adding new features with security implications, targeted reviews of the affected code can identify new vulnerabilities.
  • For Legacy Applications: If you've inherited or are maintaining older code that hasn't been reviewed for security, a baseline security code review can identify existing vulnerabilities that need to be addressed.
  • For Compliance: When preparing for security certifications or audits (e.g., SOC 2, ISO 27001, PCI DSS), security code reviews help ensure your code meets the required security standards.

The most effective approach is to incorporate security code reviews throughout your development lifecycle rather than treating them as a one-time event. This "shift-left" approach to security helps build security into your code from the beginning rather than trying to add it later.

How do you handle proprietary or sensitive code?

We understand that your source code is valuable intellectual property and may contain sensitive information. We take several measures to protect your code during the review process:

  • Confidentiality Agreements: All our security engineers sign comprehensive non-disclosure agreements (NDAs) before accessing your code.
  • Secure Access Methods: We use secure, encrypted channels for code transfer and review, such as private repositories, secure file transfers, or your own secure development environment.
  • Limited Access: Only the security engineers directly involved in your project will have access to your code.
  • Secure Storage: Any local copies of your code are stored on encrypted devices and are securely deleted after the engagement is complete.
  • On-Premises Options: For highly sensitive projects, we can arrange for reviews to be conducted on your premises or within your secure environment.
  • Code Segregation: When appropriate, we can review specific security-critical components rather than the entire codebase.

We're also open to discussing any additional security requirements or concerns you may have regarding your proprietary code.

How long does a typical code review take?

The duration of a security code review depends on several factors:

  • Codebase Size: Larger codebases naturally require more time to review thoroughly.
  • Complexity: More complex applications with numerous components, frameworks, or custom implementations require more detailed analysis.
  • Security Requirements: Applications with stringent security requirements or those handling sensitive data may require more comprehensive reviews.
  • Review Type: Automated scans can be completed relatively quickly (often within days), while manual expert reviews take longer but provide deeper insights.
  • Review Scope: Full application reviews take longer than targeted reviews of specific components or features.

As a general guideline:

  • Small applications or specific components (5,000-20,000 lines of code): 1-2 weeks
  • Medium-sized applications (20,000-100,000 lines of code): 2-4 weeks
  • Large applications (100,000+ lines of code): 4+ weeks

We'll provide a more accurate timeline after the initial scoping discussion based on your specific requirements and constraints.
