VAPT services with findings your team can fix

Vulnerability assessment and penetration testing for web apps, APIs, mobile apps, networks and cloud, reported with proof, risk ratings and clear remediation steps.

Assessment finds the gaps, penetration testing proves them

VAPT combines two activities. Vulnerability assessment uses scanners and configuration reviews to list known weaknesses across your systems. Penetration testing goes further: skilled testers try to exploit those weaknesses and chain them together, the way a real attacker would, to show what data or access could actually be compromised. Together they give a realistic picture of your exposure.

Indian businesses often need VAPT for customer audits, banking and payment partners, regulators or tenders, while global SaaS companies need it for enterprise sales and SOC 2 or ISO 27001 audits. We scope each engagement around your requirement, follow OWASP and PTES methods, test safely within agreed rules and deliver a report that works for both auditors and developers.

VAPT, in depth

  1. §1 Choosing the scope of a VAPT
  2. §2 VAPT for compliance requirements
  3. §3 From findings to closure

§1

Choosing the scope of a VAPT

Scope determines value. Testing everything superficially rarely helps, while testing the wrong systems deeply wastes budget. Start by listing systems that handle sensitive data, money or critical operations, plus everything exposed to the internet, then decide which deserve full penetration testing and which need vulnerability assessment only.

For applications, scope should include all user roles, important workflows and the APIs behind web and mobile interfaces. Many serious vulnerabilities live in APIs that the user interface never shows directly, so excluding them leaves a significant blind spot. Infrastructure scope covers external network ranges, internal networks where relevant, cloud accounts and key services such as VPNs and remote access gateways. Cloud configuration reviews often uncover risks, such as public storage or overly broad permissions, that traditional network testing misses.

Write the agreed scope into the rules of engagement, together with testing windows, excluded activities and emergency contacts. A precise scope keeps testing safe, makes reports easier to interpret and ensures that compliance evidence matches what auditors expect to see.

§2

VAPT for compliance requirements

Many organizations commission VAPT partly to satisfy regulators, auditors or customers. Requirements differ in frequency, scope and who may perform testing, so check the exact obligations that apply to your organization before planning. Common drivers are listed below, and several may apply at once.

Card payment environments fall under PCI DSS, which requires regular vulnerability scanning and penetration testing of systems in scope. Reducing that scope through hosted payment pages and tokenization can simplify testing significantly. Indian regulated entities in banking, insurance, capital markets and government often face sector-specific expectations for periodic security audits, and some engagements require auditors empaneled by CERT-In. Confirm these requirements with your compliance team before selecting a testing partner.

Even without formal mandates, enterprise customers increasingly ask for recent VAPT summaries and evidence that findings were fixed. Planning annual testing aligned with sales and renewal cycles avoids last-minute scrambles. Keep previous reports and closure evidence organized, since customers often ask for history as well.

  • PCI DSS for card payment environments.
  • ISO 27001 and SOC 2 control evidence.
  • Sector regulators such as RBI, SEBI and IRDAI in India.
  • Customer and partner contractual requirements.
  • Pre-launch checks for new applications and major releases.

§3

From findings to closure

A VAPT report is the start of work, not the end. Each finding needs an owner, a remediation plan and a deadline based on risk. Critical and high-risk issues on internet-facing systems usually require immediate attention, while lower-risk items can be scheduled into regular development cycles.

Fix root causes rather than individual symptoms. If testers found missing authorization checks on three endpoints, the underlying framework or shared code probably lacks a consistent authorization pattern. Fixing the pattern protects endpoints that were not tested as well. Retesting confirms fixes are effective and produces evidence for auditors and customers. A closure report showing each finding, its fix and verification date is often what regulators and enterprise buyers actually request.

Track trends across VAPT cycles. Recurring vulnerability types point to training needs or missing controls in the development process, such as secure code review or automated security testing in pipelines. Addressing these patterns reduces findings in the next cycle far more than fixing individual issues alone.

VAPT FAQs

Something else on your mind? Ask a consultant and get a reply within one business day.

How much do VAPT services cost?

VAPT cost depends on the number of applications, APIs, IP addresses or cloud accounts in scope, testing depth, whether testing is authenticated, compliance reporting needs and retest rounds. We share a fixed quote after a free consultation and scoping call.

How long does a VAPT engagement take?

A single web application or API typically takes one to two weeks including reporting. Combined web, mobile, network and cloud scopes take longer. The timeline is agreed during scoping, and critical findings are shared as soon as they are confirmed.

Will your VAPT report be accepted for compliance?

Our reports document scope, methodology, findings, risk ratings and closure status, which is what auditors and customers typically ask for. Some regulators require testing by specifically empanelled auditors, so check your regulator's requirement before scoping and we will tell you if it applies.

How often should we do VAPT?

At least once a year, and after major releases, infrastructure changes or acquisitions. Many customers and frameworks expect annual testing, and high-risk applications benefit from testing every release cycle.

Will penetration testing break our systems?

Testing is designed to be safe. We avoid destructive exploits, agree time windows, prefer staging environments and stop immediately if anything unexpected happens. Your team has direct contact with the testers throughout.

What is the difference between a vulnerability assessment and a penetration test?

A vulnerability assessment uses scanning and analysis to identify as many known weaknesses as possible across systems. A penetration test goes further, manually exploiting selected weaknesses to prove real impact, such as accessing sensitive data. VAPT combines both, giving broad coverage plus evidence of what attackers could actually achieve.

Do you provide a VAPT certificate?

We provide a detailed report and, after retesting, a closure statement summarizing findings and their remediation status for the tested scope and dates. Whether this satisfies a particular regulator or customer depends on their requirements, such as auditor empanelment, so confirm acceptance criteria before testing begins.

What access do you need for a VAPT?

It depends on scope. Application testing typically needs URLs, test accounts for each role and API documentation. Internal network testing needs VPN or on-site access. Cloud reviews need read-only access to accounts. All access is agreed in writing, limited to the test period and revoked afterward.
