BUG FIXING &
CODE REVIEW
CODE REVIEW
Fast, reliable fixes for apps that can’t afford downtime.
When your product is live, bugs aren’t “small issues” — they’re lost revenue, angry users, and risk.
Chainweb provides rapid bug fixing and expert code review to stabilize your web or mobile app and get you back to shipping confidently.
Outcome: fewer production incidents, faster performance, cleaner codebase.

What this service covers
Critical Bug Fixing
(Production & Pre-release)
(Production & Pre-release)
We investigate and fix bugs that impact users or business KPIs.
Examples:
You get: root-cause analysis + fix + clean PR + verification.
Examples:
- Login/signup failures, password reset issues, broken 2FA flows
- Payment and checkout bugs (Stripe/PayPal/crypto)
- API errors, inconsistent responses, webhook failures
- Mobile crashes, navigation glitches, push notification failures
- UI breakage across browsers/devices
You get: root-cause analysis + fix + clean PR + verification.
Performance & Stability Fixes
We remove bottlenecks that make your app slow or unreliable.
Examples:
• Slow pages from heavy rendering or large bundles
• Database query bottlenecks, missing indexes, N+1 problems
• Memory leaks, bad caching, timeout storms
• Background jobs failing silently
• High CPU / RAM spikes on servers
You get: measurable speed/stability improvements with before/after metrics.

You get: measurable speed/stability improvements with before/after metrics.
Code Review & Refactoring
We audit your codebase and turn it into something safe to build on.
Examples:
• Spaghetti modules split into maintainable components
• Security-sensitive areas hardened (auth, roles, file uploads)
• Legacy patterns replaced with modern, testable structure
• Type safety improvements (TypeScript, strict linting)
• Safer dependency management & upgrades
You get: a prioritized refactor roadmap + optional implementation.

Regression Protection
Fixing one thing shouldn’t break three others.
We add the right tests where it matters.
Examples:
• Unit tests for core logic
• Integration tests for APIs
• E2E tests for login, payments, onboarding
You get: reduced bug re-appearance and safer releases.

Security Consulting
We help you build a security strategy that fits your real context — not generic checklists.
Best for: companies that want a solid security foundation without wasted effort.
- risk analysis based on your actual exposure
- clear priorities and security roadmap
- cost/impact planning
- ongoing support for your IT/Dev team
Best for: companies that want a solid security foundation without wasted effort.
Cyber Threat Prevention
We secure systems and processes before they become an entry point for attackers.
Best for: raising your defense level quickly and consistently.
- server and infrastructure hardening
- exposed surface review
- access/permissions/policy optimization
- monitoring guidance and operational improvements
Best for: raising your defense level quickly and consistently.
Web Application &
Website Security Analysis
Website Security Analysis
We examine your website or web app the way a real attacker would.
We look for weaknesses in:
Deliverables: technical report + executive summary + prioritized fixes.
We look for weaknesses in:
- authentication and session handling
- APIs and integrations
- forms, inputs, and user flows
- database and sensitive data handling
- client/server configuration issues
Deliverables: technical report + executive summary + prioritized fixes.
Penetration Testing
We simulate a realistic attack in a controlled way to discover how and how far your security can be bypassed.
Best for: pre-audit checks, major releases, or scaling phases.
- black box / grey box / white box options
- web apps, infrastructure, APIs, cloud
- reproducible evidence and proof-of-exploit
- concrete remediation recommendations
Best for: pre-audit checks, major releases, or scaling phases.
Vulnerability Assessment
We identify, classify, and rank known and hidden vulnerabilities.
Best for: getting a clear snapshot of your current security posture.
- assessments for websites, web apps, networks, cloud
- severity scoring based on exploitability + impact
- step-by-step mitigation plan
Best for: getting a clear snapshot of your current security posture.

FAQ — Cybersecurity
We audit your product as a real, living system:
- website / web application (frontend, backend, APIs)
- infrastructure (servers, cloud, networks, access controls)
- processes (logging, roles, 2FA, backups, dev workflow)
It depends on scope:
- small website / landing page: 2–5 business days
- web app / portal with APIs: 1–3 weeks
- infrastructure + app + fix re-test: 3–6 weeks
No. Our testing is controlled and safe:
- most analysis is performed in low-risk modes
- aggressive or load scenarios happen only with your approval
- we follow strict stop/go protocols to avoid downtime.
You get:
- a technical report with reproducible evidence
- an executive summary for management
- a risk-based prioritized fix list
- architecture/process recommendations
- optional debrief call with your developers.
Yes. We provide:
- audit-ready reports
- verification of fixes
- security policy recommendations
- support until the audit is passed.
- Vulnerability Assessment finds and classifies weaknesses, then provides a prioritized remediation plan.
- Penetration Testing (Pentest) simulates a real attack to determine how far an attacker could actually go and what impact is possible.
Yes. You can choose:
- audit + remediation plan (your team fixes)
- audit + remediation support (we guide and verify)
- full remediation (we implement fixes if access is granted).
We follow NIST + OWASP® and add business context:
- likelihood of exploitation
- potential impact (data, finances, reputation)
- complexity of remediation
Yes — always. We also:
- limit internal access to client data
- avoid copying client data outside test environments
- deliver reports via secure channels
Pricing depends on scope and depth.
After a short 20-minute scoping call, we send a fixed

That’s common. We make sure you:
- understand risks in plain language
- get a step-by-step plan
- receive ongoing support
Both options work:
- one-time pentest for releases/audits
- ongoing security program (quarterly testing, monitoring, support).
