Sumrite

Sumrite: Expert-Led Penetration Testing (VAPT) and Security Compliance, with a VAPT Report in 48 Hours Sumrite is an expert-led penetration testing and security compliance firm that helps SaaS companies, fintechs, healthtech providers and enterprises find and fix exploitable vulnerabilities, then prove it with an audit-ready VAPT report. Based in New Delhi, India, we serve clients worldwide, including teams in the Middle East (UAE and Saudi Arabia), Europe, Australia and North America. Most security testing stops at automated scanner output. Sumrite goes further. Every engagement is run by an experienced security expert, with tools used only to speed up the routine parts. We hunt for the issues scanners and AI tools miss: broken access control, business logic flaws, authorisation bypasses and chained attacks. Every finding is manually reproduced and verified before it reaches your report, every fix is retested, and your report is delivered in as little as 48 hours. WHY TEAMS CHOOSE SUMRITE • VAPT report in 48 hours: fast turnaround for audits, enterprise deals and security questionnaires with tight deadlines. • Expert-led testing, not scanner dumps: manual penetration testing by security experts, with no copy-pasted false positives. • Every finding verified: each vulnerability is reproduced and confirmed, with clear proof of concept and business impact. • Retest included: once your team fixes the issues, we retest and update the report so it shows a clean, current result. • Mapped to 23 compliance frameworks: findings and reports are aligned to the frameworks your auditors and customers ask for, such as ISO 27001, SOC 2, PCI DSS, HIPAA, GDPR, India's DPDP Act and Saudi Arabia's PDPL. • NDA before scope: your systems, code and data are protected from the first conversation. • Trusted by 250+ teams: security, engineering and compliance teams rely on Sumrite to clear audits and enterprise security reviews. • Free first scan: start with a free external vulnerability scan at scan.sumrite.com, with no sales call and no card required. WHEN YOU NEED SUMRITE • Client onboarding: an enterprise customer won't sign until you hand over a third-party VAPT report. • Compliance audits: your ISO 27001, SOC 2, PCI DSS or regulatory audit requires independent penetration testing evidence. • Security questionnaires and due diligence: investors, partners or procurement teams want proof that your product is secure. • Product launches and major releases: you want new features, APIs or mobile apps tested before attackers find the gaps. • Ongoing assurance: you ship code every week and need continuous penetration testing instead of a once-a-year snapshot. PENETRATION TESTING AND VAPT SERVICES Web Application VAPT Expert-led web application penetration testing that covers the OWASP Top 10 and goes beyond it: broken access control, IDOR, authentication and session management flaws, injection, business logic abuse and multi-step chained attacks. Ideal for SaaS platforms, customer portals and admin dashboards. API Security Testing Penetration testing of REST, GraphQL and SOAP APIs mapped to the OWASP API Security Top 10. We test for broken object level authorisation (BOLA), broken function level authorisation, mass assignment, token reuse, rate limiting gaps, injection and excessive data exposure. Mobile App VAPT (Android and iOS) Mobile application security testing aligned to OWASP MASVS. Static analysis of the binary, manifest and entitlements; dynamic analysis on rooted and jailbroken devices; insecure local storage, keychain and keystore review; hard-coded secrets; certificate pinning and root or jailbreak detection bypass; deep link and intent abuse; and testing of the backend APIs behind the app. Network VAPT Internal and external network penetration testing covering perimeter exposure, open services, misconfigurations, missing patches, weak credentials, network segmentation, Active Directory attack paths and lateral movement. Cloud Security Assessment Security assessment and penetration testing of AWS, Microsoft Azure and Google Cloud (GCP) environments: IAM and privilege escalation paths, misconfigured storage, exposed services, network controls, Kubernetes and container security, and serverless risks. Source Code Review Manual secure code review supported by static analysis (SAST) to find injection flaws, broken authorisation, insecure cryptography, hard-coded secrets and logic bugs, with developer-friendly remediation guidance. Thick Client VAPT Penetration testing of desktop and thick-client applications, including local storage and configuration, binary and DLL analysis, traffic interception, client-side security controls and the server-side APIs they depend on. Phishing Simulations Realistic phishing and social engineering campaigns that measure how employees respond, with click-rate and report-rate metrics and practical security awareness recommendations. Red Team Operations Goal-based, adversary-emulation red team engagements across people, process and technology to test how well your organisation detects, responds to and contains a targeted attack. IoT and Hardware Security Testing Security testing of IoT devices and embedded hardware, including firmware analysis, debug interfaces, radio and network protocols, companion mobile apps and cloud backends. Continuous Penetration Testing (PTaaS) Penetration Testing as a Service for teams that ship fast. Ongoing expert-led testing as your product changes, with findings delivered continuously, fixes retested and audit-ready reports available whenever you need them. SECURITY COMPLIANCE AND RISK SERVICES Cyber Risk Assessment Structured cyber risk assessments that identify critical assets, threats and control gaps, rate each risk by likelihood and impact, and deliver a prioritised risk treatment plan aligned to ISO 27001 and other frameworks. DPDP Act Compliance (India) Support for India's Digital Personal Data Protection (DPDP) Act, 2023: personal data discovery and mapping, gap assessment, consent and privacy notice review, access control review and breach readiness. Start with our free DPDP data discovery. PDPL Compliance (Saudi Arabia and UAE) Personal Data Protection Law (PDPL) compliance support for organisations operating in Saudi Arabia and the UAE, from data mapping and gap assessment to policy review and audit-ready evidence. PII Data Discovery Find where personal and sensitive data lives across databases, file shares, email, cloud storage and endpoints, so you can reduce exposure and meet data protection obligations. Compliance-Ready VAPT for ISO 27001 and SOC 2 VAPT engagements scoped and reported to satisfy ISO 27001 and SOC 2 auditors, with findings mapped to the relevant controls. OUR PENETRATION TESTING METHODOLOGY 1. Scoping and NDA: we sign an NDA, agree on scope, testing windows and rules of engagement, and confirm the compliance frameworks your report must map to. 2. Reconnaissance and threat modelling: we map your attack surface, user roles, data flows and high-value business logic. 3. Expert-led testing: security experts perform manual black box, grey box or white box testing, using automation only to cover routine checks. 4. Verification: every vulnerability is reproduced and confirmed, with no unverified scanner findings. 5. Reporting in 48 hours: you receive an executive summary, risk-rated findings (CVSS), proof of concept, business impact and step-by-step remediation guidance. 6. Remediation support and retest: we help your developers fix the issues, retest every fix, and issue an updated report for your auditors and customers. WHAT YOU GET IN EVERY SUMRITE VAPT REPORT • Executive summary for leadership, auditors and customers • Risk-rated findings with CVSS scores and clear business impact • Reproducible proof of concept for every vulnerability • Practical, developer-ready remediation steps • Mapping to the compliance frameworks you need (ISO 27001, SOC 2, PCI DSS, HIPAA, GDPR, DPDP, PDPL and more) • Retest results and an updated report once fixes are applied BEYOND SCANNERS AND AI Automated scanners and AI tools are good at finding known, surface-level issues. They are poor at understanding how your application is supposed to work. Sumrite's security experts reverse-engineer custom protections, trace client-side controls to the server-side checks that should exist, judge real-world exploitability, and chain low-severity weaknesses into high-impact attacks. That is the difference between a report that lists issues and a report that tells you what an attacker could actually do. WHO WE WORK WITH Sumrite works with startups, scale-ups and enterprises across SaaS, fintech and banking, healthtech, e-commerce, edtech, logistics and manufacturing. Our clients include CTOs and engineering leaders who need security without slowing releases, CISOs and security teams who need independent assurance, and compliance and GRC teams who need audit-ready evidence fast. PARTNERS Sumrite partners with ISO, SOC 2 and other certification and audit firms through our partner referral programme, so their clients can get the VAPT evidence they need, quickly and to a high standard. GET STARTED Run a free external vulnerability scan at scan.sumrite.com, or contact Sumrite at sumrite.com to scope your penetration test and get your VAPT report in 48 hours. Sumrite: Probe. Prove.
