Secure code review services in India

Find the security flaws that only show up in your source code.

A person on our team reads the code you choose, at a named commit (the exact saved version of your code), against a standard you name. Some weaknesses, like a login account written into the code, usually can't be seen from outside the running app.

  • Every finding traced to a file and a line
  • A named standard, written into the scope
  • Fix verification included
  • NIST SSDF v1.1, PW.7
  • SP 800-53 SA-11(4)
  • OWASP Code Review Guide v2.0
  • MITRE CWE detection ratings

In brief

What it is
A person reads the source of the modules you choose, against a named secure coding standard.
Why it matters
For hard-coded credentials, MITRE's CWE (Common Weakness Enumeration) ratings put outside testing below reading the source.
What you get
Findings traced to a file, a line and a root cause, each with a CWE reference. Checking your fixes is included.

What reading the code finds

What a person reading your code adds.

Against outside testing, the source shows secrets the running app hides. Against a scanner, a person brings knowledge of your application.

Secrets written into the code

Passwords, tokens and keys hard-coded into the app (CWE-798). Credentials in configuration files can be found from outside, MITRE notes, but a hard-coded account for incoming logins is typically "not visible outside of the code". UIDAI, the Aadhaar authority, asks for this check in control 72.

Business logic and design flaws

Scanners leave business logic flaws untouched, OWASP's Code Review Guide says, calling it "the biggest limitation of static code analyzers". They also miss design issues a person reading the implementation can often spot.

Access control and cryptography

Against automated tools, NIST's SA-11(4) says manual review pays off where knowing your application matters: checking who may do what (access control matrices) against the application's controls, and the detail of cryptographic implementations.

Reading against running

Reading the code is rated above outside testing, not above your scanner.

MITRE's ratings put a person level with a scanner: reading the source and scanning it with a tool (static application security testing, or SAST) are both rated High for SQL injection (CWE-89), a broken or risky cryptographic algorithm (CWE-327) and hard-coded credentials (CWE-798). The case for a person rests on context, which OWASP and NIST argue in words, not ratings.

Against outside testing, the ratings favour reading. For hard-coded credentials, MITRE rates black-box testing (probing the running app without the code) only Moderate. NIST's Secure Software Development Framework (SSDF) numbers the two apart: reading code is practice PW.7, testing the running program is PW.8.

Questions to settle first

  • Is anyone reading the source? If not, that is the gap this review fills.
  • Does a scanner already run? Keep it. OWASP says "All security code reviews are a combination of human effort and technology support." Our defensive cybersecurity hub makes the case for verifying findings by hand.
  • Is the code critical? NIST says manual review is "usually reserved for the critical software and firmware components of systems".
What MITRE, OWASP, NIST and CERT-In actually say

MITRE's rows here are Manual Static Analysis - Source Code and Automated Static Analysis - Source Code, on its SOAR scale. High is "a method that succeeds frequently and does not result in many false reports"; Moderate may miss coverage or give incorrect reports. Every rating "assumes the use of best-of-breed tools, analysts, and methods". On CWE-89, automated analysis can't reach 100% accuracy and coverage, and manual analysis "might not achieve desired code coverage within limited time constraints". Narrative rows, such as CWE-327's Automated Analysis (Moderate), aren't compared.

OWASP's Code Review Guide v2.0 (July 2017), section 5.2: "SAST tools are great for coverage and setting a minimum baseline", but tools "always need human verification". Table 5 credits scanners with less manual effort, every instance found, source-to-sink analysis and exact code snippets; if a manual review gives you less locational detail, challenge it.

CERT-In's Guidelines for Secure Application Design, Development, Implementation and Operations, section 5.1: source code reviews "encompass both manual and automated reviews." SSDF PW.8.1 asks whether to test executable code "to find vulnerabilities not identified by previous reviews, analysis, or testing".

Know what you are buying

Scanners, runtime tools and a person reading the code are separate purchases.

NIST SP 800-53 Rev. 5 control SA-11 lists what an acquirer requires of a developer, each as its own obligation. This engagement is the SA-11(4) row.

Summarized from NIST SP 800-53 Rev. 5 and SSDF v1.1 (SP 800-218). SA-11's discussion also lists security architecture review, and binary or hybrid analysis.
ClassWhere NIST files itWhat it involves
Static code analysisSA-11(1)Tools find common flaws, in your code and in vulnerable, out-of-date or unsupported libraries, and document the results. Best run early, on each change. Many ignored findings (false positives) point to a tool or process problem.
Manual code review (this engagement)SA-11(4)A person reviews specific code you define, by processes you define, usually for critical components.
Dynamic code analysisSA-11(8)Tools watch the program as it runs, for memory corruption, user privilege issues and more. Fuzz testing (malformed or random input) is one type. NIST also asks for code coverage analysis.
Interactive application security testing (IAST)SA-11(9)Tools watch the application from inside (through added monitoring code) during testing, and document the results. It needs a running application.
Composition analysis of acquired componentsNot an SA-11 enhancement. SSDF v1.1 files it at PW.4.1 and PS.3.2.The provenance and risk of each component you acquire. SP 800-218 names it at PW.4.1 Example 3 and RV.1.1, never under PW.7 or PW.8.

How we work

Five steps, with the scope agreed in writing first.

  1. Scope

    You name the repository, branch and commit, and the modules in scope. OWASP warns that "it would be irresponsible to decide all modules are high risk", so your management ranks them.

  2. Context

    Language, framework and build decide whether a usable analyzer exists for your stack. Business rules, sensitive data and user roles turn a pattern into a ranked finding. Documents are often out of date, so OWASP suggests a session with your developers and lead architect. A threat model, if you have one, shows what to read first.

  3. Review

    A person reads the in-scope code. Earlier reviews and scanner output are inputs, as SSDF PW.7.2 Example 1 asks.

  4. Report

    Each finding names the file, the line and the root cause, with a CWE reference you can check against MITRE.

  5. Fix check

    Your team logs, triages and fixes findings in its own tracker, as SSDF PW.7.2 asks. We verify the fixes; that's included.

Scope and limits

What stays yours, and what this review is not.

Not a CERT-In audit

Section 4 of CERT-In's audit policy guidelines addresses CERT-In empanelled auditing organizations and their auditees. SecWiz is not an empanelled auditor. If your obligation names one from that list, the work goes to a firm on it.

Your release controls stay yours

PCI DSS (the payment card industry's security standard), at 6.2.3 and 6.2.3.1, expects software reviewed before release; for manual review, by someone other than its author, with management approval. NIST SA-11(3) has you require an independent agent to verify the developer's assessment plans and test evidence, against independence criteria you write. You operate these controls, not an outside reviewer.

No compliance verdict

We sign the report and every finding. Your risk owners sign the fix decisions and the release approval. No report from us says you satisfy SA-11 or any other control; that is for your assessor.

A bounded engagement. Which tools run in your build pipeline, what their findings are allowed to do to a build and where findings land is DevSecOps consulting. Building a threat model is a separate threat modeling engagement. To check a report before you accept it, see what a vulnerability management report contains.

If you don't hold the source code: SEBI and RBI

SEBI's Cybersecurity and Cyber Resilience Framework (CSCRF), PR.DS.S6.1, mandatory for market infrastructure institutions and Qualified REs (regulated entities): REs "shall obtain the source codes for all critical applications from their third-party service providers", or, failing that, a source code escrow or equivalent.

RBI's Master Direction on Digital Payment Security Controls, RBI/2020-21/74, 18 February 2021, clause 23, requires an escrow for third-party licensed applications. It binds Scheduled Commercial Banks other than Regional Rural Banks, plus Small Finance Banks, Payments Banks and Credit card issuing NBFCs (non-banking financial companies).

Clauses for your own contracts and process
  • CERT-In's audit policy guidelines, section 13.1.3(iii): when procuring an application, require the supplier to perform SAST, stated "in the RFPs and tenders".
  • Section 13.1.6: a defined procedure for storing and destroying the report, with a disposal time. Section 13.1.7(ii): a non-disclosure agreement before any audit activity begins.
  • SSDF PW.7.2: "record and triage all discovered issues and recommended remediations" in your own issue tracker. Its Example 4 pairs a static analysis tool with a person who reviews and fixes its findings.
  • SSDF PW.7.1 Example 1: your policies set when and how code review happens, and "may include third-party code and reusable code modules written in-house".
Review, audit and engagement types: the published vocabulary

IEEE 1028-2008, IEEE Standard for Software Reviews and Audits (published 15 August 2008; Inactive-Reserved since 7 November 2019), defines management reviews, technical reviews, inspections, walk-throughs and audits, but "procedures for determining the necessity of a review or audit are not defined".

FAQ

Questions buyers ask once the scanner has already run.

A person reading your source code for security weaknesses. OWASP's Code Review Guide: verifying that security and logical controls "are present, that they work as intended, and that they have been invoked in the right places." NIST's SSDF Version 1.1 (February 2022), task PW.7.1, separates "code review (a person looks directly at the code to find issues)" from code analysis by tools, and leaves the choice to you.

Not on the evidence MITRE publishes. MITRE rates manual and automated source-code analysis both High for SQL injection (CWE-89), a broken or risky cryptographic algorithm (CWE-327) and hard-coded credentials (CWE-798). A person adds context: NIST's SA-11(4) points to the application's requirements and context; Table 6 of OWASP's Code Review Guide to business logic flaws, design flaws and limited language scope.

The clearest scored case is hard-coded credentials (CWE-798). MITRE rates Black Box only Moderate there, because an account hard-coded for incoming logins is typically "not visible outside of the code". Both source-code rows are High. So the question is not tool against person, but whether anyone reads the source.

NIST numbers them apart: SSDF practice PW.7 is "Review and/or Analyze Human-Readable Code", and PW.8 is "Test Executable Code". A review reads what is written; a test exercises what is running. They overlap but don't substitute for each other. Vulnerability assessment of the running application is scoped separately.

Yes. Its audit policy guidelines, Version 1.0, 25 July 2025, list source code review at section 6, item ix, apart from vulnerability assessments (item iii) and application security testing (item xii). Section 4 says whom the guidelines address, so read your own obligation first. No review report satisfies, certifies or discharges a requirement; it supplies evidence your auditor evaluates.

Control 72 of UIDAI's AUA/KUA compliance checklist, Version 2.0, May 2025, sits in section J, Application Security, under the heading Application code review, and reads: "AUA/KUA should ensure that the passwords, tokens, security keys and licenses are not hardcoded in the application code." That is CWE-798 as a control. It doesn't settle who performs the work, and section J holds other obligations; read it whole before scoping.

The repository, branch and commit, and the modules your management ranks as worth reviewing. Then: language, framework and build system; business rules, sensitive data and user roles; your secure coding standard, if any; existing tool output and its triage; any threat model. Report handling and non-disclosure belong in your contract.

A published baseline, named in the scope before work starts. SSDF task PW.7.2 asks for review "based on the organization's secure coding standards"; without one, OWASP's Application Security Verification Standard (ASVS) is the usual substitute. Naming it gives any dispute about a defect something to appeal to.
