What a VAPT Engagement Covers
This is the method page: web, API, mobile, network and infrastructure, and cloud configuration. 100% coverage of agreed in-scope. US product and security teams get this work in US hours, 9am to 1pm Eastern, with delivery from India, under ISO/IEC 27001. We do not claim certified security staff. The overview that routes the rest of the set is security testing. A free external attack-surface check of one domain is the first look from the outside.
Web Applications
Authenticated and unauthenticated. Business logic as well as the standard classes a scanner lists. In scope by default: the URLs and roles you named. Out of scope until agreed: a neighbour tenant, a third-party widget you do not own, and production data we have not been given.
APIs
Authorisation between accounts is the finding that matters most, and the one automated tools miss. In scope by default: the endpoints and roles you named. Object-level access, token handling and rate limits sit in the work. A dedicated layer page is API security testing.
Mobile
The app, its storage, and what it sends. In scope by default: the builds and OS versions you named. Certificate pinning, local storage and the traffic to your API sit here. The dedicated layer page is mobile security testing.
Network and Infrastructure
Exposed services, segmentation, and the host nobody patched. In scope by default: the agreed in-scope hosts and segments. A full infrastructure-only pass sits on infrastructure security testing. Network and wireless slices sit next door when that is the only problem.
Cloud Configuration
Identity, permissions and public storage. In scope by default: the accounts and subscriptions you named. Hardening evidence for an auditor sits on cloud security and compliance. A test of the account without the application pentest sits on cloud security testing.
Retest of Agreed In-Scope
Every engagement ends with a retest of the agreed in-scope assets. Findings are revalidated after your team fixes them. That retest is part of the original work, not a second sale. 100% coverage of agreed in-scope.
Need an authorised attacker and a retest, not another scanner dump? Book a scoping call, or start with a free external attack-surface check of one domain.
Book a CallBlack-Box, Grey-Box and When Each Fits
Buyers get quoted for both and do not know the difference. Black box is closest to a real attacker. Grey box covers more per day when the application has roles. White box is a code review rather than a penetration test. We recommend grey box by default when there are roles to test. Book a scoping call if you have been quoted both and need one decision.
Black Box
No credentials, no source. Closest to a real attacker. Slower. It will miss anything sitting behind a login you did not give us. Buy this when the question is what an outsider can reach from the internet, and you can live with the gaps behind authentication.
Grey Box
Credentials and some documentation. More coverage per tester-day. This is the one to buy if the application has roles, because authorisation between accounts is the finding that matters. Vervali recommends grey box by default for a product with logins. A one-application grey-box test with a retest is the usual shape.
White Box
Source and design notes in the tester's hands. That is a code review, not a penetration test. We will say so in the quote if that is what you asked for. Do not buy a white-box day-rate and call it a pentest. The overview for SAST and DAST coordination sits on security testing.
How We Scope, Test and Retest
The method, with the tools named because a technical buyer scans for them. Written authorisation first. We do not start without it. 100% coverage of agreed in-scope. Retest of every finding after remediation is included, not sold again.
Scope and Rules of Engagement
Named assets, named roles, named windows, and what we will not touch. Third-party hosts and cloud accounts need that owner's written go-ahead as well. Scope is where these engagements go wrong. We write it down first.
Reconnaissance and Threat Modelling
What an attacker would actually try against the agreed in-scope set, before a tool is pointed at it. Attack-path analysis sits in this step, not in a PDF appendix after the scan.
Testing and Controlled Exploitation
OWASP Top 10 and ASVS levels against the surface you named. Controlled exploitation inside the limits agreed in writing. Tools used on the work: Burp Suite, OWASP ZAP, Metasploit, Tenable, OpenVAS, MobSF, Frida, Wireshark. A scanner dump with no owner is not the engagement.
Reporting and Retest
Risk-ranked findings with a path to harm, written for engineering and for an auditor. Then a retest of the agreed in-scope assets after your team fixes them. If a new release changes the surface, that is a new scope, not a free extension of the last one.
What a Penetration Test Costs and What Changes the Price
There is no single number that fits every engagement. We quote in tester-days after the agreed in-scope list is written down. We do not publish a day-rate on this page. A one-application grey-box test with a retest is the usual shape. The drivers are set out in our pentest cost guide.
What Moves the Quote
How many applications and how many roles. Whether APIs and mobile are in scope. Black box against grey box. Whether a retest is included. Whether a formal report for an auditor is required. Add a host set or a cloud account and the tester-days move. We write that list before anyone points a tool.
Shape, Not a Fake Total
A vulnerability assessment is usually shorter because it finds and ranks issues without proving an attack path. A pentest goes further. If you need exploitation and an audit-ready report, you want a pentest, not a scan. See the vulnerability assessment guide. Book a scoping call for a number against your assets.

Web · mobile · API · source · infra MobSF · FridaCompliance Mapping: What We Test For
The requirement, what it asks for, and what Vervali does about it. We test your controls and produce evidence. An auditor or a QSA signs. Vervali tests a client system for SOC 2 readiness and is not itself SOC 2 certified. Control-by-control work sits on compliance testing.
PCI DSS 11.3
Penetration testing of the cardholder environment and the segmentation that is supposed to hold. We test whether those controls would stand up to a PCI conversation. That is not a certificate. A QSA is a different vendor.
HIPAA Technical Safeguards
Access control, audit trails and transmission security on the agreed in-scope systems. We test the controls and the evidence. We do not certify a covered entity.
SOC 2 Readiness
Controls we test and evidence we produce, never a Vervali credential. An auditor issues the report. We will not write SOC 2 as something Vervali holds.
ISO/IEC 27001 Evidence
Findings and retest records a buyer can put in a file. Vervali holds ISO/IEC 27001 for its own information security. That is not a substitute for testing your estate.
Frequently Asked Questions
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. This URL is the VAPT method page.
On this site the types map to pages. Application security testing covers SAST and DAST coordination and security test design. This URL is penetration testing and VAPT: 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. This page is the method: tools, scope and the five engagements sit here. 100% coverage of agreed in-scope.
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. Book a scoping call if the surface has moved since the last report.
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. 100% coverage of agreed in-scope is the line this page will not drop.
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. Unauthorised testing is illegal. We do not claim certified security staff.
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. This URL is the VAPT method.
