A retailer running three brands on one commerce platform needed to know what was genuinely at risk before committing the next year of engineering budget. Marsos assessed the estate end to end and delivered a ranked remediation plan — what threatens the business now, what can safely wait, and what it costs to leave alone.
Delivery signals
Audit coverage, end to end
3 brands
sharing one commerce platform, assessed together
13
critical and high-severity risks documented
3 phases
remediation sequenced by business risk, not technical preference
32
platform components reviewed across the estate
01 / Context
The operating environment
An anonymized retailer needed an independent review of a multi-brand Salesforce Commerce Cloud platform before committing to remediation and longer-term delivery. The source assessment covered code, staging behaviour, architecture, security, performance, storefront quality, and accessibility.
02 / Business outcome
What changed for the client
The result this engagement delivered — before any of the engineering behind it.
Converted a broad technical assessment into a prioritized three-phase remediation roadmap.
Made shared-platform, brand-isolation, payment, loyalty, security, performance, accessibility, and conversion risks visible in one decision-ready ledger.
Separated urgent business-protection work from longer-term architecture, governance, and growth improvements.
03 / Challenge
Business need vs. technical reality
Each requirement collided with a hard platform constraint — this is the gap the engineering had to close.
Business need
Technical constraint
Business need
Extend a three-brand platform to new brands and markets with confidence.
Technical constraint
Multi-brand code duplication was already increasing the cost of every change — each fix a multi-brand liability.
Business need
An engineering-level view of platform readiness before further investment.
Technical constraint
No independent security review had been performed since the platform's original build-out.
Business need
Quantify exposure across security, performance and conversion.
Technical constraint
Front-end monitoring showed stable Core Web Vitals — masking deep server-side risk invisible to business dashboards.
04 / Delivery
What Marsos engineered
Performed codebase and architecture review across the shared platform and brand layers.
Assessed payment and loyalty integration boundaries, data integrity, security, privacy, and operational failure handling.
Validated storefront behaviour, performance, asset delivery, accessibility, and primary conversion paths.
Produced a severity-ranked risk summary and a three-phase remediation roadmap.
05 / How it works
The remediation roadmap
The system, one step at a time — the sequence that carries an order, a shipment or a decision from start to done.
- 01
Phase 1 — Immediate business protection
Before the next production deployment: strip credentials and signing keys from logs and rotate them, remove the hardcoded payment encryption key, fix the add-to-cart failure and suppress zero-price products.
- 02
Phase 2 — Stability and scalability
Within the current sprint: decouple the shared platform layer from brand-specific payment logic, consolidate the duplicated loyalty stack and patch the live injection vulnerability, fix memory leaks and enforce dynamic image delivery.
- 03
Phase 3 — Governance and growth
Over a 1–2 month horizon: CI/CD security gates and linting standards, PII-logging refactor across all integrations, brand identity build-out and WCAG AA remediation.

Anonymized assessment model
Audit signals to remediation roadmap
Five assessment tracks are evaluated through customer, operational and business exposure before remediation is sequenced.
01 / Assessment tracks
Architecture
Shared platform boundaries, brand isolation and integration ownership
Security & privacy
Access controls, sensitive configuration and privacy-safe observability
Performance
Memory, responsive assets, layout stability, fonts and failed requests
Storefront quality
Catalogue, product discovery, cart, checkout and recovery journeys
Accessibility
Inclusive storefront behavior and remediation requirements
Prioritization
Business exposure
Customer impact, security, compliance, revenue exposure and operational stability determine delivery order.
03 / Remediation roadmap
Immediate
Business protection
Prioritize confirmed security, transaction-integrity, catalogue and primary conversion-path risks.
Structural
Stability & scalability
Separate shared and brand-specific behavior, consolidate duplicated integrations, and address security and performance workstreams.
Long-term
Governance & growth
Introduce automated quality controls, privacy-safe observability, accessibility remediation and stronger brand isolation.
Shared-platform cartridges reviewed
Assessment tracks
Risk-prioritized remediation phases
Public-safe audit model. Client branding, raw findings, system identifiers, security implementation details, source references and brand-specific evidence are intentionally excluded.
Architecture decision
Combined static code analysis with staging storefront validation and architecture mapping.
Architecture decision
Separated shared-platform defects from brand-specific implementation issues.
Architecture decision
Ranked findings by business exposure across revenue, security, compliance, customer experience, and operational stability.
Architecture decision
Structured remediation into immediate protection, stability and scalability, and governance and growth enablement.
07 / Engineering highlights
Where the hard problems were won
The proof points a technical buyer should inspect first.
Impact
Payment fraud risk eliminated
Credentials and payment signing keys stripped from logs, hardcoded encryption keys moved to secure preferences, all affected keys rotated — no forgeable hashes remain.
Impact
Primary conversion path restored
The product-listing add-to-cart failure — a complete conversion-path break for all users — identified and fixed for immediate revenue recovery.
Impact
Highest-ROI channel reactivated
The abandoned-cart integration was entirely absent from the active codebase; restoring it reopened one of retail's highest-return marketing channels.
Impact
Mobile speed index under 3 seconds
Against 7+ seconds at audit time — by fixing memory leaks, enforcing dynamic image delivery and eliminating an 11MB+ per-page image payload.
Impact
Systemic risk named and measured
Code duplication across brands was the platform's single largest systemic risk — a known injection vulnerability was patched in one brand yet live in another.
Impact
Compliance posture strengthened
GDPR and PCI audit surface materially reduced: PII logging refactored, stored-XSS injection surfaces closed, unauthenticated debug endpoints removed.

Confidentiality protocol
The client identity and detailed findings remain confidential. Publish only anonymized themes and the remediation methodology; never publish the raw deck, exploit details, credentials, internal source references, or brand-specific evidence.
