Penetration Testing Services for Web Apps, APIs and Cloud
Manual penetration testing for web apps, APIs, mobile apps and cloud: real attack paths found, proven and explained, with fixes your developers can apply and a free retest.
Automated scanners find known issues. Attackers chain small weaknesses together: a predictable ID, a missing permission check, an exposed admin route. A penetration test finds those paths before they do.
Codersarts penetration testing services combine manual testing by security engineers with automated tools, and because we're also developers, we can help fix what we find.
What Is Penetration Testing?
Penetration testing (a pentest) is an authorized, simulated attack on your application or infrastructure to find vulnerabilities an attacker could exploit. Testers follow methods such as the OWASP Testing Guide and PTES, prove each finding safely, rate its severity, and report how to fix it.
A pentest goes further than a vulnerability scan: a scan lists likely issues, while a pentest confirms which ones can actually be exploited and how far an attacker could get.
Who This Is For
SaaS companies asked for a pentest report by enterprise customers
Startups preparing for SOC 2 or ISO 27001
Apps handling payments, health or student data
Teams launching a major release or new API
Apps built quickly or with AI tools
What We Test
Web applications
Authentication, access control, injection, business logic and session handling, based on the OWASP Top 10.
APIs
REST and GraphQL endpoints, broken object-level authorization, rate limits and data exposure.
Mobile apps
Android and iOS apps and their backend APIs. See mobile app security.
Cloud configuration
AWS, Google Cloud and Azure permissions, storage and network exposure. See cloud misconfiguration audit.
AI and LLM features
Prompt injection, data leakage and tool misuse. See LLM security.
Retesting
A free retest to confirm each fix works.
Black-Box vs Grey-Box vs White-Box Testing
Approach | What testers know | Best for |
|---|---|---|
Black-box | Only the public app | Simulating an outside attacker |
Grey-box | User accounts and some documentation | Most SaaS apps; best value |
White-box | Source code and architecture | Deepest coverage before major launches |

Common Findings We Help Fix
Problem | Usual cause | Fix |
|---|---|---|
Users can view other users' data | Missing object-level checks | |
Weak login and sessions | No MFA or rate limits | |
Secrets in code or front end | Keys committed to Git | |
Outdated libraries with known CVEs | No dependency updates |
How Much Does a Penetration Test Cost?
Pentest cost depends mainly on scope: how many apps, roles, API endpoints and environments are tested, and how deep the testing goes.
Scope | Typical timeline | Typical cost |
|---|---|---|
Single web app, grey-box | 1 to 2 weeks | $3,000 to $8,000 |
Web app and API | 2 to 3 weeks | $8,000 to $20,000 |
Web, API, mobile and cloud | 3 to 5 weeks | $20,000 to $50,000+ |
What changes the cost: number of user roles and endpoints, mobile platforms, cloud accounts, white-box code review, certified reporting and retest rounds.
Ranges are typical for a global team. Your price is fixed after scoping, before any work starts.
Ways to Start Small
Starting point | Best for | From |
|---|---|---|
A quick baseline before a full pentest | $199 | |
Checking the most common web risks | $199 | |
A ranked bug list for an existing platform | $199 | |
Ongoing fixes with a fixed budget | $290 for 10 hours |
How We Work
Scope. Apps, environments, roles and rules of engagement, agreed in writing.
Recon. Map the attack surface and technologies.
Test. Manual and automated testing against agreed targets.
Report. Findings with severity, proof and fix steps.
Fix. Your team fixes, or we help through fix tasks.
Retest. Confirm fixes and issue a final report.
What You Receive
An executive summary for leadership and customers
Detailed findings with severity and proof
Step-by-step fix guidance
A free retest and final report
A letter of attestation on request
Example Engagement: Pentest Before an Enterprise Deal
An illustrative example based on the pattern we see most often. Client details are kept confidential.
The situation: A B2B SaaS company needed a pentest report within a month to close an enterprise contract.
What we did:
Ran a grey-box test of the web app and API with three user roles
Found an object-level authorization flaw and weak password reset
Helped fix both issues and retested
The result: The company shared a clean final report and attestation letter, and the deal closed on schedule.
Mistakes to Avoid
Treating an automated scan as a pentest
Testing production without agreed rules
Getting a report but never retesting fixes
Testing once and never after major changes

Fixed-price tasks for small jobs, so you can start without a large contract
Plain-language reports your developers and leadership can both act on
Experience with startups, SaaS products and enterprise buyers worldwide
You own all code, reports and accounts
Frequently Asked Questions
How much does penetration testing cost?
A single web app usually costs $3,000 to $8,000; web and API $8,000 to $20,000; broader scopes $20,000 or more.
How long does a pentest take?
Most web app and API tests take 1 to 3 weeks, plus time for fixes and retesting.
What is the difference between a pentest and a vulnerability scan?
A scan lists likely issues automatically. A pentest manually confirms what can be exploited and how far an attacker could get.
Will testing affect our live app?
We usually test a staging environment. Production testing follows agreed limits and times.
Do you provide certified reports?
Yes, through a CERT-In empanelled partner when a certified report is required.
How often should we pentest?
At least yearly and after major changes, or as your customers and compliance framework require.
