Application security testing
Find every security issue before it ships.
Whatever your stack ships, Web, Mobile, Thick Client, API (REST · GraphQL · gRPC · MQTT), Cloud. Tested manually by operators who publish CVEs. Every finding lands with a working proof-of-exploit, developer-ready fix guidance, and a re-test.
Coverage
Web · Mobile · Thick Client · API · Cloud, every application class.
Evidence
Working proof-of-exploit and developer-ready fix guidance on every finding.
Re-test included
We verify your fixes at no extra cost. One engagement, closed loop.
The window from vulnerability discovery to exploitation has gone from weeks to hours.

On record
Why application security testing
Risk lives in your application's logic.
Real risk lives in your auth model, your workflow logic, your API resolvers. AppSec testing reads the application like an attacker reads it, from the outside, with intent, until small flaws compound into something the dev team can ship a fix for and the auditor will accept.
What we pentest
Every application we ship against.
Pick the application class, same depth across each. Manual chained-exploit testing on every surface, not a scanner sweep.
Web Application
Server-rendered and SPA web apps. Auth flows, session handling, OAuth/OIDC, multi-tenant boundaries, business logic, security headers, SSRF, chained against your real user roles.
PAST THE SAMPLE REPORT.
What 47 chained pre-auth exploits actually look like.
- 01IDOR to admin
Object-reference flaws plus weak session validation. Anonymous to admin.
- 02Mass assignment to RCE
Body-bound model fields overwrite admin properties, escalate into deserialization.
- 03SSRF to cloud role
Server-side request forgery into IMDS for AWS role assumption from anonymous endpoints.
- 04OAuth to account takeover
State-parameter prediction, PKCE downgrade, redirect-URI bypass.
- 05Business logic to privilege
Time-of-check race against payment, account merge, role assignment.
What we test —
Eight application surfaces. One engagement.
These are the surfaces SecureLayer7's app-sec practice operates across. Every surface in scope by default; intensity tunes per engagement.
Authentication & Session
Login bypass, session fixation, token prediction, password reset flaws, MFA weaknesses, federation bypass, OAuth/OIDC misconfig.
Authorization & Access Control
IDOR, broken object-level auth, privilege escalation, multi-tenant bleed, role/scope-checking gaps in API + UI.
Business Logic
Price manipulation, workflow abuse, state-machine bypass, race conditions — the chained exploits unique to your application.
API surfaces (REST · GraphQL · gRPC · MQTT)
REST + GraphQL — BOLA, mass assignment, query-cost, schema introspection. gRPC — protobuf field abuse, reflection leaks, streaming-method DoS, mTLS misconfig. MQTT — broker auth, ACL bypass, retained-message exposure, topic-injection across IoT/real-time brokers.
Data Storage & Encryption
Local storage exposure, key management, encryption-at-rest verification, transit ciphers, certificate pinning.
Injection & Execution
SQLi, XXE, SSTI, command injection, deserialization, prototype pollution — tested manually with chained exploits, not just signatures.
Configuration & Secrets
Exposed admin panels, misconfigured headers, leaked secrets in JS bundles, third-party SDK exposure, server-side config drift.
Web3 / Smart Contracts
Solidity audit (reentrancy, integer over/underflow, access-control gaps, unchecked external calls, gas-griefing, oracle manipulation), EIP-712 signature reuse, wallet-connect phishing flows, multicall + delegatecall abuse, ERC-20/ERC-721 approve-and-drain, bridge replay, MEV / front-running on dApp UX.
Findings inside systems that already passed audit. The chain runs through gaps no checklist names.
“Compliance is a snapshot. Application pentest is the stress test the snapshot can't show, the chain an attacker actually walks when your auditor isn't watching.”
APPLICATION SECURITY METHODOLOGY.
Eight phases. Logic to dependency.

Built for India engagements
What changes when we deliver here.
Compliance scoping
CERT-In empanelment cited on every AppSec engagement letter
Regulatory framework
RBI Master Direction Annex 1 application controls mapped per finding
Local engagements
Pune and Bengaluru fintech AppSec engagements run quarterly
Local pricing
INR pricing with GST HSN 998313 and e-invoicing for ≥10 Cr clients
Compliance scoping
DPDP Section 8 Reasonable Security evidence packaged with report
What Indian AppSec buyers ask first.
Does the report satisfy RBI's annual application pentest line item?
Yes. The cover letter cites RBI Master Direction 2016 Annex 1 and our CERT-In empanelment number. RBI inspectors accept this format.
How does this align to DPDP Section 8 evidence?
Each finding maps to a Reasonable Security Safeguard category. The audit pack ships with the data-flow notes your DPO needs for Section 8 filing.
Do you cover authenticated business-logic flows for fintech apps?
Yes. Each role gets its own test pass. We chain logic bugs into account-takeover and limit-bypass proofs that NPCI and RBI auditors recognise.
Quote and invoice format?
INR-denominated SOW. GST-compliant invoice with HSN 998313. E-invoicing supported for ≥10 Cr turnover clients.
Delivery in India
CERT-In empanelled AppSec. DPDP Section 8 ready.
Findings map to RBI Annex 1 application security clauses and SEBI CSCRF Protect-1. DPDP Section 8 Reasonable Security evidence packaged with each report.
