Engineering Practical Data Protection and System Integrity.
Coexis Tech builds ERP platforms and business applications for organizations handling sensitive student records, patient encounters, plant formulations and financial transactions. We implement verified architectural controls across databases, user roles and network perimeters.
Core Security Architecture Pillars
Security is enforced at every layer: client interactions, application logic, database transactions and hosting infrastructure.
Client Data Ownership & Strict Confidentiality
You retain 100% legal ownership of your business data, customer records, and master registers. We sign Non-Disclosure Agreements (NDAs) before discovery begins.
- Mutual Non-Disclosure Agreement (NDA) executed prior to architectural review
- Your database records and operational data are never shared, monetized, or utilized for third-party training
- Complete data export provided in standard formats (SQL dump, CSV, JSON) upon project conclusion or contract termination
- Explicit data segregation ensuring no multi-tenant data leaks between customer accounts
Role-Based Access Control (RBAC) & Authentication
Access permissions mirror your organizational hierarchy so each department operator sees only what is necessary for their role.
- Granular role-permission matrices separating front-desk clerks, clinical staff, accountants, and administrators
- Secure password hashing utilizing industry-standard salted hashing algorithms (bcrypt/Argon2)
- Strict session management with automated timeout windows for sensitive financial and patient registers
- Audit trails logging critical operational events, cash transactions, and administrative changes
Application-Level Bot & Abuse Defenses
Public endpoints and enterprise portals are protected against automated bots, brute force, and payload manipulation.
- Google Cloud reCAPTCHA Enterprise score-based token verification utilizing the backend CreateAssessment API
- Server-side sliding-window rate limiting restricting excessive submissions per client IP
- Strict request body size enforcement (maximum 16 KB) on public submission routes to prevent memory exhaustion
- Strict same-origin (CORS) validation rejecting cross-site forgery attempts
- Strict Zod input validation schemas, HTML entity escaping, and CRLF email header injection stripping
Network Perimeter & Transport Security
All web interactions occur over encrypted channels, backed by Cloudflare edge security and origin protection.
- Enforced HTTPS using TLS 1.3 encryption across all website routes, client portals, and API endpoints
- Hardened HTTP response headers including Content-Security-Policy (CSP), X-Frame-Options, and X-Content-Type-Options
- Cloudflare edge WAF rules blocking non-POST requests to sensitive enquiry endpoints and filtering known server probe patterns
- Origin firewall configurations restricting direct unproxied ingress
Database Reliability, Backups & Disaster Recovery
Scheduled backup procedures safeguard your operational records against accidental loss or hardware failures.
- Automated daily database snapshots with retention schedules aligned with client compliance requirements
- Offsite backup storage isolated from the active production runtime server
- Transactional integrity (ACID compliance) preventing partial writes or database corruption during concurrent batch processes
- Documented restoration runbooks tested periodically to ensure rapid recovery during emergency recovery scenarios
Secure Development & Incident Response
Continuous code auditing, dependency hygiene, and a transparent incident resolution procedure.
- Codebase dependency audits using automated vulnerability scanners during production builds
- Dedicated security contact channel (coexistech@gmail.com) for prompt reporting of concerns
- Triage response within 24 business hours for reported security observations
- Honest, transparent communication: we do not claim unverified certifications (such as ISO 27001 or SOC 2); we stand by verifiable engineering practices
Responsible Security Disclosure Policy
If you believe you have discovered a security vulnerability or anomalous behavior in any Coexis Tech web property or software component, we appreciate your prompt assistance in reporting it responsibly.
Please include the URL, reproduction steps, and technical impact.
Our engineering leads acknowledge reports promptly and prioritize verified remediations.
