// The 9-Step Framework

OWASP WSTG. NIST SP 800-115. Zero shortcuts.

Manual testing first, automation second. Each phase maps to the OWASP Testing Guide and NIST's 4-phase model (planning · discovery · attack · reporting).

01 · SCOPE

Planning & Rules of Engagement

Targets, test windows, creds, auth modes (black/grey/white), out-of-scope, legal ROE sign-off.

02 · RECON

Information Gathering

WSTG-INFO: passive recon, tech-stack fingerprinting, endpoint discovery, sitemap enumeration.

03 · MAP

Threat Modeling

Trust boundaries, data flows, abuse cases, MITRE ATT&CK initial-access & execution paths.

04 · CONFIG

Configuration & Deploy Review

WSTG-CONF: headers, TLS, CORS, cookies, error handling, deployment exposure, WAF bypass.

05 · AUTH

Auth & Session

WSTG-ATHN/ATHZ/SESS: login, MFA, JWT/OAuth, IDOR, privilege escalation, session fixation.

06 · INPUT

Input Validation & Injection

WSTG-INPV: SQLi, NoSQLi, XSS (reflected/stored/DOM), SSRF, SSTI, XXE, command injection.

07 · BIZLOG

Business Logic & APIs

WSTG-BUSL + OWASP API Top 10: workflow abuse, race conditions, mass assignment, rate limits.

08 · CLIENT

Client-Side & Crypto

WSTG-CLNT/CRYP: DOM XSS, postMessage abuse, JS secrets, crypto misuse, weak algorithms.

09 · REPORT

Report, Retest, Debrief

Executive + technical report, PoC videos, CVSS scoring, ATT&CK mapping. Free retest in 30d.

// Aligned Frameworks

One engagement. Three authoritative references.

We don't pick one. Every finding is traceable to OWASP, NIST, and MITRE simultaneously — so dev, compliance, and detection teams all get what they need.

ATT&CK for Enterprise

Every exploitable finding is tagged with the TTPs an attacker would use — so your detection team can respond.

  • TA0001 · Initial Access (T1190, T1078)
  • TA0002 · Execution (T1059)
  • TA0003 · Persistence (T1098, T1136)
  • TA0004 · Privilege Escalation (T1068)
  • TA0005 · Defense Evasion (T1550)
  • TA0006 · Credential Access (T1110, T1555)
  • TA0009 · Collection (T1005)
  • TA0010 · Exfiltration (T1041)
  • CAPEC patterns cross-referenced
// OWASP Top 10 · 2021

Full coverage — not lip service.

Every OWASP Top 10 category is exercised with manual tests and, where useful, supporting automation. Findings reference the exact sub-category.

A01

Broken Access Control

IDOR, privilege escalation, forced browsing, CORS misconfig, CSRF on state-changing ops.

A02

Cryptographic Failures

Weak TLS, deprecated ciphers, hardcoded keys, weak hashing, sensitive data in transit/storage.

A03

Injection

SQL, NoSQL, OS command, LDAP, XPath, template (SSTI), header, and log injection.

A04

Insecure Design

Threat-model gaps, missing rate limits, workflow abuse, trust-boundary violations.

A05

Security Misconfiguration

Default creds, exposed admin, verbose errors, XXE, outdated frameworks, missing headers.

A06

Vulnerable & Outdated Components

SCA of libraries, CVE triage, transitive dependency risk, unsafe plugin registries.

A07

Identification & Auth Failures

Credential stuffing, weak recovery, JWT flaws, session fixation, missing MFA.

A08

Software & Data Integrity

Insecure deserialization, unsigned updates, CI/CD poisoning, dependency confusion.

A09

Security Logging & Monitoring

Missing audit trail, log injection, retention gaps, IR-blind endpoints.

A10

Server-Side Request Forgery

SSRF via webhooks/imports/PDF, cloud-metadata pivots, internal service discovery.

// Engagement Modes

Black box. Grey box. White box.

Pick the engagement model that fits your risk appetite and timeline. We'll recommend based on scope in the kickoff call.

// EXTERNAL

Black Box

Zero information. We simulate a motivated external attacker — pure recon to exploit.

Best for: public-facing apps · annual pentest · bug-bounty prep
// BALANCED

Grey Box

We get low-privilege creds and basic architecture notes. Maximum finding density per hour.

Best for: SaaS products · authenticated flows · most engagements
// DEEPEST

White Box

Source access + architecture docs + creds. Uncovers logic flaws automated tools never find.

Best for: critical systems · fintech · pre-compliance
// Standards & Certifications

Findings mapped. Auditors satisfied.

Reports reference the controls your compliance team tracks. Our consultants hold industry-recognized offensive-security certifications.

// FAQ

What clients ask before every VAPT.

What's the difference between VA and PT?
VA (Vulnerability Assessment) finds and ranks weaknesses — breadth. PT (Penetration Testing) exploits them to prove real impact — depth. We combine both so you get complete coverage and verified severity. Reports flag exploitable vs. theoretical findings explicitly.
Do you test production or staging?
Default is a staging environment that mirrors prod. If staging isn't representative, we test prod during agreed windows with throttled, non-destructive payloads. All DoS/storage-heavy tests are opt-in only and pre-announced.
Do you test APIs and mobile backends?
Yes — REST, GraphQL, gRPC, and WebSocket are covered. OWASP API Top 10 mapping included. Mobile backend testing can be bundled with mobile app VAPT if your scope needs both.
How do you handle false positives?
Every reported finding is manually validated with a working PoC. If we can't reproduce it, it doesn't ship. Automated-scanner noise is filtered before the draft report — you won't see padded findings.
Will the test crash our app?
No. Destructive payloads (DoS, brute-force lockouts, mass data writes) are excluded by default. Any non-standard test is cleared in writing before execution.
How much does it cost?
Scope-driven. Small apps (<50 endpoints, single role) start around ₹1.2L. Typical SaaS VAPT lands ₹2L–₹6L. Complex multi-tenant / multi-role / API-heavy engagements are quoted after a free scoping call.
Can you sign off on a PCI / ISO / SOC 2 audit requirement?
Yes — our report format satisfies PCI-DSS 11.4 penetration testing requirements, ISO/IEC 27001 A.12.6.1, and SOC 2 CC7.1 controls. Letter of attestation provided on request.
