How we work

A process that closes every door behind us.

/ 01

Scope

We map your assets, agree on rules of engagement, and define exactly what gets tested.

/ 02

Test

Manual, attacker-mindset testing with the same techniques real adversaries use, not just automated scans.

/ 03

Report

CVSS-rated findings with proof-of-concept evidence and clear, prioritised remediation steps.

/ 04

Retest

We verify your fixes at no extra cost, so every door we opened is confirmed closed.

Who we are

We are Vertbits Lab.

Vertbits Lab is a cybersecurity firm specialising in security assessments. We simulate real-world attacks against your infrastructure to uncover vulnerabilities before adversaries do.

Founded on the principle that defense begins with understanding offense, we deliver rigorous, methodology-driven security testing across web applications, networks, APIs, and cloud environments.

What is VAPT? A complete guide to vulnerability assessment & penetration testing

What VAPT actually involves, how it differs from a vulnerability scan, what it costs, how often you need it, and the questions to ask any provider.

Frequently asked questions

Questions people ask before a security test.

Straight answers to what teams usually want to know before booking a VAPT or penetration test.

A vulnerability assessment finds and prioritises as many weaknesses as possible across your systems. A penetration test goes further and actively exploits those weaknesses to prove the real-world impact. VAPT combines both, so you learn where you are exposed and what an attacker could actually do. Read the full guide.

Pricing depends on scope: the number of applications, APIs, IP ranges, and the depth of testing required. A single web app costs far less than a full assessment across web, API, network, and cloud. Tell us what you want tested and we will scope a fixed quote, with a free retest always included.

Most engagements run one to three weeks. A single web application typically takes 5 to 10 business days, while a full assessment covering web, API, network, and cloud can take three weeks or more, including reporting and a remediation retest.

At least once a year, and after any major change such as a new application, an infrastructure migration, or a significant release. Teams handling regulated or sensitive data, or working toward PCI DSS, often test quarterly.

No. Automated scanners catch known issues at scale but miss business logic flaws, chained attack paths, and authorisation bypasses, and they produce false positives. Our testing is manual and attacker-minded, with every finding validated by a human before it reaches your report.

No. We agree rules of engagement before testing begins, including scope, testing windows, and which techniques are off-limits. Destructive testing is never run without explicit approval, and most engagements have no noticeable impact on production.

An executive summary for leadership and a technical report for engineers, with CVSS-rated findings, proof-of-concept evidence, and prioritised remediation steps, plus a free retest after you fix the issues to confirm they are closed.
