Deep Security Audit of Application Source Code and Implementation of DevSecOps

We identify critical vulnerabilities, API-key leaks and logical errors in the code of your web applications, mobile backends and microservices before they reach production. We combine automated scanning (SAST/DAST/SCA using Semgrep, SonarQube, Snyk) with thorough manual review of critical business modules and build automated security checks (Security Gates) into your CI/CD pipelines.

✓ Full code review according to OWASP Top 10 and OWASP API Security Top 10
✓ Deep manual analysis of critical business logic: payment modules, authentication and balance processing
✓ Dependency analysis (SCA & SBOM): identifying unsafe third-party libraries in npm, composer, pip
✓ Seamless DevSecOps integration: automatic security audit of each Pull Request in GitHub/GitLab

Security at the development stage

Why fixing vulnerabilities in code is 30 times cheaper on the development stage than after release

Most data leaks occur due to simple validation errors of user-entered data or API logic

[ 01 ]

Prevention of client data and database theft

Detecting SQL injections, dangerous direct links to objects (IDOR) and authentication vulnerabilities through which attackers can load the user database.

[ 02 ]

Protection of Business Logic and Financial Transactions

Automatic scanners often miss logical vulnerabilities (for example, the possibility to send a negative amount or use a promo code twice). Our experts manually check financial modules.

[ 03 ]

Protection against supply chain poisoning (Supply Chain Attacks)

Modern application on 80% consists of third-party open-source libraries. We check each dependency for the presence of known CVEs and backdoors.

[ 04 ]

Accelerating releases without compromising security (DevSecOps)

Built-in repository security gates automatically block merging of malicious code into the main branch, teaching developers to write secure code from the first day.

[ ENGINEERING REGULATIONS FOR CODE ANALYSIS ]

What is included in a professional audit of the output code (AppSec)

Full spectrum of static, dynamic, and manual code base research under strict NDA protection

[ STEP 01 ] SAST Analysis

Automated static scanning (SAST)

We launch high-precision analyzers Semgrep, SonarQube and specialized rules tailored to your language (PHP, Python, JavaScript/Node.js, Go, Java, C#).

[ STEP 02 ] Manual Review

Deep manual code analysis (Manual Code Review)

Senior AppSec engineers read critical code branches, analyze encryption mechanisms, session handling, token generation, and business rules.

[ STEP 03 ] SCA & SBOM

Audit of third-party dependencies and libraries (SCA & SBOM)

We are forming a complete list of components (Software Bill of Materials) and checking all third-party packages for the presence of unresolved CVEs and dangerous licenses.

[ STEP 04 ] Secret Scanning

Search for Hidden Secrets and Access Keys (Secret Detection)

We scan the entire Git commit history for the presence of accidentally left passwords to databases, SSH private keys, AWS tokens or payment APIs.

[ STEP 05 ] DAST & API

Dynamic interface security testing (DAST & API Security)

We are testing the deployed application through OWASP ZAP scanners and attack emulation tools on REST/GraphQL endpoints without access to the sources.

[ STEP 06 ] CI/CD DevSecOps

Implementation of DevSecOps pipeline in GitHub Actions / GitLab CI

We configure rules for automatic scanning of each commit: if a critical vulnerability is found in a new PR, the build stops until it is fixed.

[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

Source code is the main intellectual property of your business. We sign a strict non-disclosure agreement (NDA) with clear material liability. Work is conducted on isolated encrypted workstations without the right to transfer to third parties, and after the project is completed and accepted, all local copies are guaranteed to be destroyed.

Automatic scanners look for only syntax errors or outdated function calls. They do not understand your business logic. A scanner will never understand that user "A" can change the ID in a request and read user "B"'s invoice (IDOR vulnerability), or that double charging occurs when the payment button is rapidly pressed twice (Race Condition). Such things are found exclusively by a person during manual review.

You will receive a structured report with two parts: 1) Executive Summary (for management) with an overall security assessment and business risks; 2) Detailed technical document for programmers, where for each vulnerability the file, exact line, threat description and a ready example of fixed code ("was / became") are specified.

Yes. All our comprehensive audit packages include a mandatory re-review (Re-review) stage. After your team commits the fixes, our experts re-inspect these files and confirm the successful elimination of vulnerabilities in the final conclusion.

DevSecOps transforms security from a one-time event into a continuous process. Instead of searching for vulnerabilities once a year before release, your developers will see security scanner warnings directly in their Pull Request even before the code reaches the test or production environment. This saves weeks of time and protects the project from accidental errors.
