Find and fix the security holes in your web, mobile, and cloud systems before someone else does — with a fix plan your developers can actually ship.
Cybersecurity & Application Security
Find and fix the security holes in your web, mobile, and cloud systems before someone else does — with a fix plan your developers can actually ship.
Most breaches don't start with a hacker. They start with a shortcut.
An exposed API key in a repo. An admin panel with no rate limit. A dependency that hasn't been updated in two years. These aren't exotic attacks — they're the ordinary gaps that ship when a team is moving fast. We find them, rank them by real-world risk, and hand you a fix plan your developers can work through.
What We Check
- Web & mobile application testing — authentication, session handling, access control, injection, and business-logic flaws, tested against the OWASP Top 10
- Secure code review — manual review of auth, payment, and data-handling paths, plus automated SAST across the codebase
- Dependency & supply-chain audit — every third-party package scanned for known CVEs and unmaintained risk
- Cloud & infrastructure config — IAM permissions, storage bucket exposure, secret management, and network rules on AWS, GCP, or Azure
- API security — rate limiting, token lifecycle, CORS policy, and data-exposure review
How the Engagement Runs
- Scope & access (2 days) — we agree in writing what's in scope, get read access, and set testing rules so nothing production-critical is disrupted
- Testing (4-6 days) — automated scanning plus manual testing of the paths that matter: login, payment, admin, and data export
- Report (2 days) — every finding with severity, reproduction steps, business impact, and a specific fix — not a raw scanner dump
- Fix support & retest — we can implement the fixes ourselves or support your team, then retest to confirm each issue is closed
Who This Is For
Fintech and e-commerce teams handling payment or personal data. SaaS companies whose enterprise buyers are asking security questions in the procurement process. Any team preparing for ISO 27001, GDPR, or PCI-DSS and needing to know where they stand before a formal audit.
What You Get
- A prioritised findings report — critical to low, with proof-of-concept for each
- A developer-ready remediation plan with code-level guidance
- A free retest of every critical and high finding after you fix them
- A one-page executive summary you can share with clients or investors
