Altius IT delivers independent web application security audits for cloud-native platforms, e-commerce and retail checkout flows, healthcare and biotech portals, gaming services, and aerospace supplier applications across Seattle and the Pacific Northwest. Our auditors perform OWASP Top 10 assessments, OAuth/JWT security reviews, and comprehensive API penetration testing to secure your applications against account takeover, supply chain attacks, and modern web threats.
Seattle's technology economy is built on cloud-native platforms operated by AWS and Azure, e-commerce engines from Amazon, Costco, Nordstrom, Expedia, and Zillow, healthcare portals at Fred Hutchinson, Seattle Children's, and UW Medicine, and gaming services from Bungie, Valve, Microsoft Gaming, and Nintendo of America. These applications process billions of transactions, protect highly regulated data, and serve millions of users worldwide. Our web application security audit is designed to address the specific risks facing Pacific Northwest organizations building modern web applications with complex authentication, microservices architectures, and extensive API surfaces.
We systematically test your web applications against the OWASP Top 10, including injection flaws, broken authentication, sensitive data exposure, XML external entities, broken access control, security misconfigurations, cross-site scripting, insecure deserialization, vulnerable components, and insufficient logging. For Seattle's cloud-native platforms, broken access control in multi-tenant environments and broken authentication in OAuth/OIDC implementations are the most critical risk categories, especially when those platforms serve enterprise and federal customers.
Our auditors perform in-depth testing for SQL injection, cross-site scripting, and cross-site request forgery vulnerabilities using both automated scanning and manual exploitation techniques. E-commerce platforms accepting user reviews, gaming services accepting user-generated content, and healthcare portals handling provider notes are all particularly susceptible to these attack vectors.
We audit REST, GraphQL, and SOAP APIs for authentication bypass, excessive data exposure, broken object-level authorization, mass assignment, and rate limiting gaps. Seattle's e-commerce, cloud, and gaming architectures often expose hundreds of endpoints across microservices, creating an expansive attack surface that demands systematic testing beyond what automated scanners can provide, especially given the supply chain attacks targeting cloud-native deployments.
Our audit evaluates OAuth 2.0 and OpenID Connect implementations, JWT token validation, session management, and multi-factor authentication flows. We test for token leakage, improper scope validation, authorization code interception, and refresh token abuse. For Pacific Northwest e-commerce, gaming, and telecom operators, OAuth/JWT security is the foundation that protects accounts against credential stuffing and account takeover at internet scale.
We test for SSRF vulnerabilities that could allow attackers to access internal microservices, cloud metadata endpoints, or sensitive backend systems. Microservices architectures running on AWS and Azure are especially vulnerable to SSRF because internal service-to-service communication often lacks the same authentication controls applied to external-facing endpoints.
Our approach combines automated vulnerability scanning with expert manual penetration testing to identify both common vulnerabilities and complex business logic flaws. This is especially important for e-commerce checkout, gift card, and loyalty flows, plus gaming microtransactions, where transaction manipulation and race conditions can only be detected through skilled manual testing.
We test for business logic flaws including privilege escalation, payment manipulation, workflow bypass, and data leakage through application-specific functionality. Retail and gaming platforms face risks around order tampering, gift card abuse, microtransaction manipulation, and insufficient idempotency controls that can lead to financial loss and customer trust damage.
Our auditors evaluate web server configurations, framework settings, error handling, CORS policies, CSP headers, and container security settings. We review Kubernetes ingress configurations on AWS EKS and Azure AKS, service mesh policies, and API gateway settings that govern how traffic flows through cloud-native microservices architectures.
We assess TLS/SSL configurations, cipher suite selections, certificate management, mTLS implementation between microservices, and data encryption practices. For organizations processing payments, protected health information, or controlled unclassified information for aerospace and defense customers, end-to-end encryption across the entire microservices chain is essential for both security and compliance with PCI-DSS, HIPAA, CMMC, and FedRAMP.
For e-commerce and retail technology applications processing credit card data, we evaluate PCI DSS compliance requirements including tokenization implementations, secure API design, encryption of payment data in transit and at rest, and access control mechanisms across microservices boundaries.

Thorough 360-degree review covering your technology, people, and processes.
Every engagement includes follow-up support to ensure vulnerabilities are properly mitigated.
The Seattle area is a hub for cloud computing, e-commerce, aerospace, healthcare and biotech, gaming, and wireless. Pacific Northwest web applications manage sensitive data for millions of users, process billions in retail and travel payments, and integrate with hundreds of third-party services through complex API ecosystems. This interconnected architecture creates an expansive attack surface where a single vulnerable API endpoint, misconfigured OAuth flow, or exposed cloud storage bucket can expose entire platforms. Our web application security audit helps Seattle organizations systematically identify and remediate these risks.
Cloud-native multi-tenant applications face tenant isolation risks where cross-tenant data leakage can result in catastrophic breaches affecting thousands of customers and trigger SOC 2 and FedRAMP findings. E-commerce and retail platforms must secure complex checkout, gift card, and loyalty flows against manipulation, race conditions, account takeover, and credential stuffing. Healthcare portals must safeguard PHI under HIPAA and the Washington My Health My Data Act. Gaming services serving minors must address COPPA and microtransaction abuse. API-first architectures expose dozens or hundreds of endpoints that each require proper authentication, authorization, rate limiting, and input validation. Our cybersecurity audit covers the full stack from infrastructure to application layer.
An independent web application security audit from Altius IT provides Seattle organizations with a detailed vulnerability assessment, prioritized remediation roadmap, and documented evidence of security testing that satisfies SOC 2, HIPAA, PCI-DSS, CMMC, and customer security questionnaires from Amazon, Microsoft, Boeing, and other Pacific Northwest enterprise buyers. Our Auditor Opinion Letter gives your enterprise clients, federal procurement officers, and partners documented assurance that your web applications have been independently tested by CISA-certified professionals. For organizations also building mobile apps, we offer mobile application security audits alongside web application testing. Learn more about our team and methodology.
In addition to Seattle proper (Downtown, Capitol Hill, Belltown, South Lake Union, and Pioneer Square), Altius IT serves businesses throughout King County and the Eastside (Bellevue, Redmond, Kirkland, Issaquah, Sammamish, Mercer Island, Renton, Kent, Federal Way, Auburn, Burien), Pierce County (Tacoma), and Snohomish County (Everett, Lynnwood, Bothell). Our web application security audits are conducted both remotely and on-site, providing flexible engagement options for organizations across the Pacific Northwest.
