Cybersecurity
Security built into the architecture, not bolted on after a breach.
Overview
Most security work gets treated as a checklist run once before launch. XETUP treats it as part of the engineering process itself: threat modeling during architecture, secure coding practices during build, and independent assessment before anything reaches production users.
This matters most in regulated or high-stakes environments. Systems that move money, hold personal data, or sit inside a bank's infrastructure carry a different bar than a marketing website, and XETUP's engineering team builds to that bar by default rather than retrofitting it under deadline pressure.
What's Included
- Application security assessments (OWASP-aligned) across web, mobile, and API surfaces
- Black-box, white-box, and gray-box penetration testing, matched to what the engagement needs to prove
- Secure-by-design architecture review for new systems, including data flow and access control
- Role-based access control (RBAC) and audit-trail design for systems handling sensitive transactions
- Infrastructure hardening: server configuration, network exposure, credential and secrets management
- Ongoing monitoring and incident response support for systems already in production
Built For
- Banking and fintech platforms handling reconciliation, settlement, or payment data
- SaaS products storing customer data at scale
- Enterprises replacing legacy systems that were never security-reviewed
- Government and public-sector systems handling citizen data
- Startups about to face their first enterprise client's security questionnaire
- E-commerce platforms processing payment and checkout data at volume
- Any team that needs an assessment from a vendor who also understands the codebase, not just an external auditor with no build context
How We Actually Work
Named practices, not marketing language. This is the specific methodology applied to this service line, described as what it is, not as a certification XETUP does not hold.
Black-box, White-box & Gray-box Testing
Three testing postures, chosen by what needs proving: black-box simulates a real outside attacker with zero internal knowledge, white-box reviews the actual source and architecture for logic flaws automated scanners miss, gray-box blends both for a realistic insider-risk view.
Threat Modeling (STRIDE)
Every new system is mapped against Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, and Elevation of privilege before a line of code ships, not after.
OWASP ASVS & Top 10 Alignment
Application reviews are checked against OWASP's Application Security Verification Standard and Top 10 risk list, the same reference framework regulators and enterprise auditors expect to see cited.
Secure SDLC
Security review gates sit inside the development lifecycle itself: architecture, code, and pre-release, instead of a single audit bolted on right before launch.
Zero Trust Access Principles
No system component is trusted by default, including internal ones. Every request is authenticated and authorized on its own merits, which is what makes RBAC and audit trails actually hold up under review.
Reasons Teams Choose Us for This
One accountable team
The engineers who build the system are the same ones who secure it. No handoff gap between a dev team and a bolted-on external auditor who has never seen the codebase.
Remediation included, not upsold
A finding gets fixed as part of the engagement. It is not packaged as a separate follow-on sale once the report lands.
Regulated-grade standards by default
Practices aligned with OWASP, and reviewed against the same bar banking and fintech engagements require, applied to every system regardless of industry.
Support doesn't end at launch
Monitoring and incident-response support continue once the system is live, not just during the pre-launch review window.
Questions About This Service
We do both. An assessment that ends in a report nobody has time to act on doesn't actually reduce risk, so remediation is part of the engagement, not a separate follow-on sale.
Yes. Most of our security work is on live systems, not greenfield builds. We assess without disrupting uptime, then schedule fixes around your release cycle.
Yes, findings and remediation are documented in a format suitable for internal audit or regulatory review, including OWASP-aligned assessment coverage.
Scanners catch known patterns. Our assessments include manual review and architecture-level threat modeling, the kind of logic flaws and access-control gaps automated tools miss entirely.
Critical findings are flagged immediately, not held for a final report. You get a fix path the same week, not at project close.
