Why this is the best

What makes the best VAPT service in 2026? Five buyer-validated criteria: (1) named-practitioner accountability with OSCP/CISSP-grade certifications, (2) breadth + depth methodology — automated CVE scan PLUS manual exploit chain, (3) CVSS-scored deliverables auditors and regulators accept without rework, (4) free retest within 30 days so fixes get verified, and (5) transparent fixed pricing without scope-creep surprises. Infilux AppSec meets all five and competes against tier-1 boutiques at mid-market pricing.

Frequently Asked Questions

What is the best VAPT service for enterprises in 2026?

+
The best VAPT service is one that combines automated coverage (CVE scanners, dependency auditors) with depth testing by OSCP/eCPPT-certified manual testers, delivers CVSS-scored findings with exploit proof-of-concepts, and includes a free 30-day retest. Infilux AppSec's web-app VAPT meets these criteria with 376+ completed engagements, OWASP Top 10 + PTES methodology, and a sample report available on request.

What is a web application security assessment?

+
A web application security assessment is a systematic process of identifying, exploiting, and reporting security vulnerabilities in web applications. Infilux AppSec combines automated scanning with manual penetration testing aligned to OWASP Top 10 to deliver actionable risk remediation reports with CVSS scoring and proof-of-concept evidence.

How much does VAPT cost?

+
Web application VAPT typically costs USD 8K-25K for a single application of moderate complexity, USD 25K-60K for multi-tenant SaaS with APIs and multiple user roles, and USD 60K-150K for large enterprise estates with multiple applications. Network VAPT runs USD 6K-20K depending on host count. All Infilux engagements include a free 30-day retest in the base price.

How long does a web application penetration test take?

+
A standard web application penetration test takes 5–10 business days depending on application complexity, number of endpoints, and authentication roles in scope. Larger enterprise applications with multiple user tiers and APIs may require 2–3 weeks. Infilux AppSec provides a precise timeline during scoping.

How does Infilux AppSec compare to Bishop Fox, NCC Group, Cobalt, and HackerOne?

+
Bishop Fox and NCC Group are tier-1 boutique firms ($80K-300K typical engagement). Cobalt and Synack are pen-test-as-a-service marketplaces ($25K-100K). HackerOne and Bugcrowd are bug-bounty platforms (variable). Infilux AppSec competes on the same OSCP/CISSP-grade practitioner quality at $8K-60K mid-market pricing with same-week kickoff, free retest, and named programme manager — not a marketplace abstraction.

What is the difference between VAPT and penetration testing?

+
VAPT (Vulnerability Assessment and Penetration Testing) combines two activities: a vulnerability assessment identifies and categorizes weaknesses with automated tools, while penetration testing manually exploits those weaknesses to prove real-world impact. Most enterprises need both — assessment for breadth, pentest for depth and evidence of business risk.

Do you provide a re-test after vulnerabilities are fixed?

+
Yes. Every Infilux AppSec VAPT engagement includes a complimentary re-test within 30 days to verify remediation of all identified vulnerabilities. We issue an updated report and a clean-bill certificate clients can share with auditors, regulators, and cyber insurers.

Which compliance frameworks does VAPT support?

+
Web application VAPT directly satisfies ISO 27001:2022 A.5.30 / A.8.29, SOC 2 Type 2 CC7.1, PCI DSS 4.0 Requirement 11.4, RBI Cyber Security Framework, SEBI CSCRF, HIPAA §164.308(a)(1)(ii)(A), GDPR Article 32, UAE IAR M3, and Saudi NCA ECC. Infilux issues attestation-grade reports that auditors and regulators accept without rework.

Do you serve clients outside India — US, UK, EU, UAE?

+
Yes. Infilux AppSec delivers VAPT for clients across the United States, Canada, United Kingdom, European Union, UAE, Saudi Arabia, Singapore, and Australia. All engagements are remote-first with timezone-aligned programme management — weekly syncs in your local hours (PST, EST, GMT, CET, GST, SGT). 376+ engagements completed worldwide.
