What We Test

A web application security audit from Altius IT is a controlled, real-world assessment of your web applications and supporting infrastructure performed by Certified Information Systems Auditors (CISA), testing for the OWASP Top 10 and more than 35,000 known vulnerability types.

Emulating the techniques used by real attackers, our team combines automated scanning with manual penetration testing and code-assisted review. Automated tools provide broad coverage; manual testing finds the business logic, authorization, and chained vulnerabilities that scanners miss. A typical engagement covers:

For organizations that process payment data, we assess your application against PCI DSS requirements for secure cardholder data handling.

Testing APIs too? Web application audits include testing of the APIs your application uses. For API-only services, microservices, partner integrations, and mobile backends, see our dedicated API security audit and penetration testing service, which tests against the OWASP API Security Top 10.

Our Audit Process

A structured, three-phase approach that scopes your applications, tests them thoroughly, and leaves your team with a clear remediation plan.

01

Planning & Preparation

We work with your stakeholders to define scope, identify critical applications and data flows, and review your security policies and controls. You receive a detailed proposal covering project scope and tasks, pricing options, CVs of the assigned audit team, and sample reports.

02

Technical Assessment

Our team performs vulnerability scanning, manual penetration testing, and configuration review against your in-scope applications. Testing is coordinated with your team and scheduled to avoid disruption to production operations.

03

Reporting & Remediation

We deliver a report with prioritized findings, risk ratings, and specific remediation steps for each vulnerability. We then walk your team through the results and remain available for 90 days of free post-audit support. Retesting of remediated findings is available.

Who Needs This Audit

This audit is for organizations that operate customer-facing web applications and need independent proof they are secure.

SaaS Providers Platforms whose customers expect documented application security before they buy.
E-commerce & Payments Stores and payment platforms handling cardholder data under PCI DSS.
Healthcare Organizations Applications handling PHI under the HIPAA Security Rule.
Financial Services Firms with regulatory obligations and high-value transaction flows.
Vendor & Compliance Reviews Companies preparing for customer security reviews, vendor assessments, or compliance audits.

Compliance Alignment

We benchmark your web application security against recognized frameworks and map findings to the requirements that matter to your business. If you are preparing for a customer security review or a formal certification, the audit report and Auditor Opinion Letter give you documented, independent evidence of your security posture.

Frequently Asked Questions

Answers to common questions about our web application security audit and penetration testing services.

Understanding Web Application Audits

A penetration test simulates an attacker attempting to exploit vulnerabilities. A web application security audit includes penetration testing but goes further: we also review your security controls, configurations, policies, and compliance alignment, and we issue a formal report and Auditor Opinion Letter as Certified Information Systems Auditors.

The report includes an executive summary, a prioritized list of findings with risk ratings, evidence for each vulnerability, and step-by-step remediation instructions. We review the report with your team and provide 90 days of free support while you remediate.

Scope & Coverage

Yes. APIs used by your web application are tested as part of the audit. For API-only services, microservices, and mobile backends, we offer a dedicated API security audit aligned to the OWASP API Security Top 10.

No. Testing is scheduled and coordinated with your team, and intrusive techniques are agreed upon in advance. We can test staging environments where preferred, and we monitor for any impact throughout the engagement.

Engagement Details

Most engagements take two to four weeks from kickoff to final report, depending on the size and complexity of the application. Larger applications with multiple user roles may take longer. We confirm the timeline in your proposal before work begins.

Cost depends on application size, complexity, and user roles. We provide a fixed-fee quote after a scoping call, so you know the full cost before work begins.

At minimum annually, and after any major release, architecture change, or security incident. Many compliance frameworks, including PCI DSS, require testing at least annually and after significant changes.

Typically: the URLs in scope, test accounts for each user role, a point of contact, and a signed authorization to test. For deeper coverage we may request architecture diagrams. We walk you through everything during planning.

Strengthen your web applications against evolving threats, meet regulatory requirements, and protect your data, intellectual property, and customers.
