Vulnerability Assessment and Penetration Testing Consultancy

What VAPT is usually taken with

Few organisations stop at one standard, and the second costs far less than the first — the clauses that take longest are the ones they share. Where VAPT sits next to something else, this is what carries over.

• ISO/IEC 27001 consultancy — shares clauses 4 to 10 with this standard, so context, leadership, competence, internal audit and management review are built once and audited together.
• SOC consultancy — shares clauses 4 to 10 with this standard, so context, leadership, competence, internal audit and management review are built once and audited together.
• NIST consultancy — shares clauses 4 to 10 with this standard, so context, leadership, competence, internal audit and management review are built once and audited together.

Certified to more than one, you hold a single management system with one set of objectives, one internal audit programme and one management review — audited in one visit. Run as separate systems they cost roughly twice as much to keep, which is the usual reason a second certificate feels harder than it was.

Finding the holes before someone else does

Vulnerability assessment and penetration testing are related but different activities. The assessment is broad and largely automated: enumerate hosts, services, applications and configurations, and identify known weaknesses. The penetration test is narrow and manual: take those weaknesses, chain them together, and prove what an attacker could actually reach. One tells you what is exposed. The other tells you what that exposure is worth. Buying only the first and calling it a test is a common and expensive shortcut.

It is requested by enterprise customers before onboarding a vendor, by regulators and schemes including PCI DSS and supervisory guidance in banking and insurance, by insurers pricing cyber cover, and by boards after an incident somewhere in their industry. Scopes commonly cover the external perimeter, internal network, web and mobile applications, APIs, cloud configuration and, where the client is willing, people and physical access. Younger companies usually arrive because a customer contract now demands an annual test.

Scanning, then attacking, with rules agreed in writing

Work begins with scope and rules of engagement in writing: targets, exclusions, test windows, data handling, escalation contacts and what happens if something breaks. That document protects both sides. Reconnaissance and discovery follow, then authenticated and unauthenticated scanning to build a picture of the attack surface. Findings from tooling are verified by hand, because unvalidated scanner output wastes your engineers' time and destroys confidence in the exercise. We take the noise out before you ever see it.

Then the manual phase. Testers work through injection, authentication and session handling, access control and privilege escalation, business logic abuse, misconfiguration and exposed services, and where it is in scope, lateral movement from an assumed breach position. Exploitation is used to prove impact, not to cause damage: we demonstrate reach and stop there. Evidence is captured as we go, with request and response detail so your developers can reproduce each issue without a follow up call.

The report, the retest and the fixes that stick

You receive an executive summary written for people who do not read HTTP requests, and a technical report with every finding rated by severity and exploitability, with reproduction steps, evidence and specific remediation guidance rather than a link to a generic advisory. Findings sharing a root cause are grouped, since fixing one pattern beats fixing twenty symptoms. A retest after remediation confirms closure and produces a clean summary you can hand to customers.

What tends to change is prioritisation. Development teams that once saw a long undifferentiated list now see three issues that put data at risk and forty that do not, and they fix the three. Repeat findings across cycles point at a process problem, usually in code review or build hardening, which is a more useful conversation than any individual bug. Testing then becomes a check on known ground rather than a fresh discovery every year.
