Focused testing for the systems attackers actually touch.
GK Data provides practical offensive security for web, API, mobile, network, and cloud targets, plus website security management for small businesses. Engagements are scoped around the target, the risk, and the reporting needed to make decisions.
Services
No bloated menu. Just the areas where focused recon, manual testing, and clean validation create useful security outcomes.
Web Application & API Penetration Testing
Manual testing for authentication, authorization, business logic, injection, XSS, SSRF, CORS, data exposure, and chained impact across modern web apps and APIs.
Explore service →Mobile Application Security Testing
Android and iOS testing across app behavior, API traffic, session handling, local storage, client-side controls, and backend integration paths.
Explore service →Network & Cloud Security Review
Recon-heavy review of exposed services, DNS, certificates, cloud storage exposure, identity risk, reachable attack paths, and practical misconfiguration impact.
Explore service →Small Business Website Security Management
Security-minded WordPress and small business website management: hardening, backups, monitoring, plugin hygiene, incident cleanup, and remediation support.
Explore service →Security Advisory Retainer
Ongoing offensive security guidance, triage, validation, and practical support for teams that need security judgment without building a full internal security function.
Explore service →Remediation Verification
Retesting and validation to confirm fixes actually remove the reported risk, with concise notes that owners and developers can act on.
Explore service →Engagement Model
Every target is different, so scope and pricing are based on assets, access, timeline, risk, and deliverable depth.
AI-assisted reconnaissance. Manual verification.
Custom AI agents can help organize recon, correlate signals, build testing strategy, and keep complex investigations documented. Validation stays human. No unverified AI output goes into a report.
Scoped Before Testing
Targets, exclusions, access, timelines, risk priorities, and communication rules are defined before hands-on work starts.
Evidence That Holds Up
Findings include reproduction steps, screenshots or request evidence where useful, risk context, and business impact.
Readable Reporting
Executive summaries stay clear for owners while technical sections give developers enough detail to fix the issue.
Retesting When Needed
Fix validation can be included so teams know whether a remediation actually closed the exposure.
