Use Case in Software Testing: How to Turn One Into Test Cases
Every path through a use case becomes at least one test case. A worked bank-transfer example shows the test table, and ISTQB's 2023 and 2025 syllabus changes explain…
Security Testing Services: Web, API, Mobile and Cloud
Vervali provides application security testing and VAPT across web, API, mobile and infrastructure: SAST and DAST coordination, security test design, API and mobile security testing, and testing of your controls for PCI DSS and HIPAA. Work is black-box or grey-box, with a retest of the agreed in-scope assets. Delivery is in US hours from India, under ISO/IEC 27001.

Which Test Fits the Problem
The application, an authorised attacker, the API, mobile, the network, or the controls an auditor will ask for. Pick the problem you actually have.
Application Security Testing
You need SAST and DAST coordinated into the release, plus a security test design, rather than a scanner dump with no owner. Stay on this page for that work, including PCI DSS and HIPAA control testing.
Penetration Testing and VAPT
You need an authorised attacker, a risk-ranked report and a retest of the agreed in-scope assets. Penetration testing and VAPT is the method page.
API Security Testing
Authorisation between accounts is the finding that matters, and automated tools miss it. API security testing is the layer page.
Mobile Security Testing
The app, its storage and what it sends are in play, not only the API behind it. Mobile security testing is the layer page.
Network and Infrastructure
The problem is hosts, segmentation and exposed services, not the application layer. Infrastructure security testing is that page.
Cloud Security and Compliance
Identity, public storage and evidence an auditor will accept. Cloud security and compliance covers the configuration review.
Compliance Testing
You need your controls tested for PCI DSS, HIPAA or SOC 2 readiness, not a certificate we cannot issue. Compliance testing is the control-by-control page.

Book a Scoping CallApplication Security Testing
SAST and DAST that someone owns, a written scope, and evidence for PCI DSS and HIPAA. We test your controls. We do not certify, and Vervali is not itself SOC 2 certified.
SAST and DAST Coordination
Static findings and runtime findings land on different teams and get counted twice. We design which checks run in the pipeline, which run on a build, and which need a person, so the noise does not become the work.
Security Test Design
What is in scope, which roles get tested, what is out, and what success looks like before a tool is pointed at the application. Scope is where these engagements go wrong. We write it down first.
PCI DSS and HIPAA Testing
We test whether your controls and evidence would stand up to a PCI DSS or HIPAA conversation. That is not a certificate. If you need a QSA or a covered-entity opinion, that is a different vendor.
Retest of Agreed In-Scope Assets
Reports are risk-ranked and written for engineering and for an auditor. Every engagement ends with a retest. 100% coverage of agreed in-scope. We do not claim certified security staff.
Five Recent Engagements
Bank, payments, marine, fintech and gaming work where noise, time-to-fix or audit prep actually moved. 100% coverage of agreed in-scope.
Anonymous 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 from 5 days to 5 hours, and a 3.5 times high-risk closure rate.

Infrastructure VAPT across the exposed surface. Tools used on the engagement: Burp Suite, Metasploit, Tenable, OpenVAS and Wireshark. The report was risk-ranked. Findings were retested after remediation.

There is no single price that fits every engagement. The quote moves with the number of applications and roles, whether APIs and mobile are in scope, black-box against grey-box, whether a retest is included, and whether an auditor-ready report is required. Vervali quotes in tester-days after scope is agreed. A one-application grey-box test with a retest is the usual shape. The drivers are set out in our pentest cost guide.
A vulnerability assessment is usually shorter than a penetration test because it finds and ranks issues without proving an attack path. Price still follows scope: how many hosts, applications and cloud accounts sit in the agreed in-scope set, and whether a retest is included. We quote after that list is written down. If you need exploitation and an audit-ready report, you want a pentest, not a scan. See the vulnerability assessment guide.
On this site the types map to pages. Application security testing covers SAST and DAST coordination and security test design. Penetration testing and VAPT covers web, API, mobile, source code and infrastructure, black-box and grey-box, with a retest. API, mobile and infrastructure security testing are the layer pages. Cloud security and compliance, and compliance testing, cover control testing for PCI DSS, HIPAA and SOC 2 readiness.
It is a timed, authorised attempt to break a web application the way an attacker would: unauthenticated and authenticated, including business logic, not only the OWASP Top 10 classes a scanner lists. Vervali uses Burp Suite and OWASP ZAP alongside manual testing, then retests every finding after remediation. Method, tools and the five engagements sit on the penetration testing page.
After every major release or infrastructure change, and at least annually if you have a PCI DSS or similar obligation. High-risk products often run quarterly. The useful cadence is tied to change, not to a calendar slogan. A retest of the last findings is not a substitute for a new test when the attack surface has moved.
Yes. Every engagement ends with a retest of the agreed in-scope assets. Findings are revalidated after your team fixes them, and that retest is part of the original work rather than a second sale. If a new release changes the surface, that is a new scope, not a free extension of the last one.
Testing is lawful with written authorisation from the asset owner. Vervali does not start without that document, a named scope and agreed rules of engagement. We do not test assets you do not own or control. If a third-party host or a cloud account is in scope, we need that owner's written go-ahead as well.
A vulnerability assessment finds and ranks weaknesses. A penetration test goes further: controlled exploitation, attack-path analysis and proof of what an attacker could actually reach. Buy a VA when you need a list. Buy a pentest when you need to know which findings matter and you need a report an auditor will read. Both end with a retest of the agreed in-scope assets.
