It is the core foundation of your brand reputation and sales pipeline. Enterprise customers will not sign contracts or process payments on platforms that lack audited security controls. A mid-market fintech provider handling automated payment processing and invoicing hired FixrWeb to prepare for an upcoming SOC 2 Type II compliance audit. While their product worked well, automated external scans flagged several security vulnerabilities, missing security headers, and permissive server permissions that threatened their audit timeline. Our security engineering team was brought in to conduct a complete security audit, resolve every open vulnerability, and establish bank-grade protection across their entire web platform. ## Key vulnerabilities identified during the audit Our security review examined the public marketing site, customer portal, billing APIs, and user login flows. We discovered four critical areas that needed immediate attention: 1. **Unsafe form inputs:** Custom invoice notes allowed raw text entry without sanitization. This created a vulnerability where malicious scripts could execute inside an administrator's browser session. 2. **Incomplete account boundary checks:** Certain account API routes checked if a user was logged in, but failed to verify if that user owned the requested invoice ID. This could allow unauthorized account data viewing. 3. **Outdated software dependencies:** Five underlying software libraries contained known vulnerabilities that required immediate updates. 4. **Missing browser security headers:** The web servers lacked standard security headers that tell web browsers to enforce strict encryption and block suspicious cross-domain requests. ## Practical hardening steps implemented FixrWeb established a step-by-step remediation plan to fix every gap and protect customer data: ### 1. Cleaning and validating all user inputs We updated every customer input field across the portal. All incoming text strings are now cleaned and validated on the server before reaching the database. This prevents malicious code execution completely. ### 2. Enforcing strict account permission boundaries We added centralized permission checks for every data request. The system now verifies that the logged-in user explicitly owns the organization record they are trying to view. If account IDs do not match, access is immediately blocked. ### 3. Deploying an edge web application firewall We placed a global firewall in front of the application. The firewall inspects every incoming web request in under 5 milliseconds. It automatically blocks automated scanner bots, limits password attempt rates to 5 per minute, and isolates internal administrative pages behind strict IP access lists. ### 4. Enforcing full browser security headers We configured the web servers with mandatory browser security headers. These headers force browsers to use encrypted connections exclusively and block unauthorized script execution. ## Audit results and long-term peace of mind Thirty days after completing the security hardening project, the client underwent their official external audit: - **SOC 2 Type II Audit:** Passed cleanly with **zero compliance findings**. - **Security Vulnerabilities:** Resolved 100% of identified security gaps. - **Botnet Exploits:** Blocked over 500,000 automated exploit attempts per month at the edge firewall. - **Customer Trust:** Secured enterprise sales deals requiring verified SOC 2 compliance documentation. By addressing security proactively, the fintech provider turned a compliance roadblock into a competitive advantage that wins new enterprise customers. --- ### Q: How does a website security audit help fintech companies pass SOC 2 audits? A: A security audit identifies hidden vulnerabilities, missing encryption headers, and weak access controls. Fixing these items ensures your platform passes external auditor reviews without compliance delays. ### Q: What is the biggest security risk for online payment platforms? A: Unsanitized form inputs and weak account authorization checks. These gaps allow malicious scripts or unauthorized users to view sensitive customer billing data. ### Q: How does an edge firewall protect financial websites from automated attacks? A: An edge firewall inspects incoming web traffic before it reaches your main server. It blocks malicious bot scans, brute-force password attempts, and SQL attacks automatically.
