QA Testing Services for SaaS Startups: How Vervali Works
How Vervali tests a SaaS startup's product: what to test first, when to outsource, manual or automation, the monthly cost at published rates, and how the free pilot…
Penetration Testing and VAPT Services
for Web, API, Mobile and Infrastructure
Vervali delivers vulnerability assessment and penetration testing across web applications, APIs, mobile apps, source code and infrastructure, black-box and grey-box, with threat modelling, attack-path analysis, controlled exploitation and revalidation after fixes. Reports are risk-ranked and audit-ready, and every engagement ends with a retest of the agreed in-scope assets.

What a VAPT Engagement Covers
Every layer an attacker can reach, tested against a written scope and closed out with a retest.
Web Applications
Authenticated and unauthenticated testing of the URLs and roles you name, including business logic flaws that scanners never flag.
APIs
Broken object-level access, token handling and rate limits on the endpoints you name. Deeper API work runs through API security testing.
Mobile
Local storage, certificate pinning and the traffic each build sends to your API. Platform-specific depth comes from mobile security testing.
Network and Infrastructure
Exposed services, weak segmentation and unpatched hosts across the agreed segments. Infrastructure-only passes run through infrastructure security testing.
Cloud Configuration
Identity, permissions and public storage in the accounts you name. Account-level reviews run through cloud security testing.
Retest of Agreed In-Scope
Every engagement ends with a retest after your fixes, included in the original price. 100% coverage of agreed in-scope assets, every time.
A scanner dump is not a penetration test.
Free Attack-Surface CheckBlack-Box, Grey-Box and When Each Fits
The right approach depends on what you need to prove. For products with logins, grey box finds more per day.
Black Box
No credentials and no source, closest to a real outside attacker. Choose it when the question is what anyone on the internet can reach.
Grey Box
Credentials and some documentation, so testers reach the authorisation flaws between accounts. Our default for any product with user roles.
White Box
Source code and design notes in the tester's hands. That is a secure code review, and we name it that way in the quote.
How We Scope, Test and Retest
Written authorisation first, named tools throughout, and a retest of every finding before we close.
Scope and Rules of Engagement
Named assets, roles, test windows and exclusions, agreed in writing. Third-party hosts and cloud accounts need their owner's written approval too.
Reconnaissance and Threat Modelling
We map what an attacker would actually try against your scope, and plan attack paths before a single tool is pointed at it.
Testing and Controlled Exploitation
OWASP Top 10 and ASVS checks with controlled exploitation inside agreed limits, using Burp Suite, OWASP ZAP, Metasploit, Tenable, OpenVAS, MobSF, Frida and Wireshark.
Reporting and Retest
Risk-ranked findings with a clear path to harm, written for engineers and auditors, then a retest of the agreed in-scope assets after your fixes.
What a Penetration Test Costs and What Changes the Price
Priced in tester-days against a written scope, so you know the number before testing starts. Our pentest cost guide covers the drivers.
What Moves the Quote
The number of applications and roles, whether APIs, mobile, hosts or cloud accounts are in scope, black box or grey box, and whether you need an auditor-ready report.
Assessment or Pentest
A vulnerability assessment finds and ranks issues and costs less. A pentest proves the attack path. Our vulnerability assessment guide helps you choose.
Five Recent Engagements
Real VAPT work, anonymized by sector, with the tools named and every finding retested.
Bank · VAPT and audit evidence
Before: vulnerability noise was burying the work that mattered, fixes took over 40 days and audit preparation took five days. After: 68% less vulnerability noise, time to fix under 16 days, audit preparation down from 5 days to 5 hours, and high-risk findings closed 3.5 times faster.

Infrastructure VAPT across the exposed surface of a digital recharge and payments platform, using Burp Suite, Metasploit, Tenable, OpenVAS and Wireshark.
Marine Technology
Web and infrastructure VAPT for a global marine technology organisation, tested against the OWASP Top 10 with risk-ranked findings.
Fintech Platform
API VAPT on a fintech platform, focused on authorisation between accounts, the flaw class automated tools most often miss.
SaaS Gaming
End-to-end VAPT across web, mobile, API, source code and infrastructure, with MobSF and Frida on mobile and one retest.
Compliance Mapping: What We Test For
We test your controls and hand over the evidence your auditor or QSA needs to sign off.
PCI DSS 11.3
Penetration testing of the cardholder data environment and the segmentation meant to protect it, with evidence ready for your QSA.
HIPAA Technical Safeguards
Access control, audit trails and transmission security tested on the agreed systems, with findings mapped to each safeguard.
SOC 2 Readiness
We test your controls for SOC 2 readiness and produce the evidence your auditor reviews. Control-by-control work runs through compliance testing.
ISO/IEC 27001 Evidence
Findings and retest records you can file as evidence, produced by a team that holds ISO/IEC 27001 for its own information security.
Frequently Asked Questions
Vervali is listed on Clutch at $25 to $49 an hour, and a penetration test is quoted in tester-days once the scope is written down. The price moves with the number of applications and roles, whether APIs and mobile are included, black box or grey box, and whether you need an auditor-ready report. A one-application grey-box test with a retest is the most common starting point.
A vulnerability assessment usually costs less than a penetration test, because it finds and ranks weaknesses without proving an attack path. The price follows the number of hosts, applications and cloud accounts in scope, and whether a retest is included. If you need proof of exploitation and an audit-ready report, budget for a full penetration test instead.
The main types are vulnerability assessment, penetration testing, static and dynamic application security testing (SAST and DAST), API and mobile security testing, network and infrastructure testing, cloud configuration review and compliance testing for frameworks such as PCI DSS, HIPAA and SOC 2. A VAPT engagement combines assessment and penetration testing across the layers you choose.
It is a timed, authorised attempt to break into a web application the way a real attacker would, both before and after login. Testers go beyond the OWASP Top 10 to probe business logic and authorisation between accounts. We combine Burp Suite and OWASP ZAP with manual testing, then retest every finding after your team fixes it.
Run one after every major release or infrastructure change, and at least once a year if you carry PCI DSS or similar obligations. High-risk products often test quarterly. Tie the cadence to change rather than the calendar. A retest of old findings does not replace a new test once the attack surface has moved.
Yes. Every engagement ends with a retest of the agreed in-scope assets after your team applies fixes, and the retest is included in the original price. Each finding is revalidated and marked closed or still open in the final report. If a new release changes the attack surface, we scope it as a fresh test.
Penetration testing is legal when the asset owner gives written authorisation. We never start without a signed authorisation, a named scope and agreed rules of engagement covering test windows and exclusions. If a third-party host or cloud account is in scope, its owner must approve in writing too. Testing without that permission is illegal.
A vulnerability assessment finds and ranks weaknesses across your systems. A penetration test goes further, using controlled exploitation and attack-path analysis to prove what an attacker could actually reach. Choose an assessment when you need a prioritised list, and a penetration test when you need proof and a report an auditor will accept. Both end with a retest.
