Application Security Audits

Application Security Audits That Find What Automated Scanners Miss

You need an application security audit that goes deeper than a scan report full of false positives. Whether you are looking for an application security audit company to test your web application before launch, need experienced application security auditors to audit application security on a platform handling sensitive data, or want a thorough security audit for applications that are already live in production, the goal is always the same: find the vulnerabilities before someone else does. We deliver end-to-end application security audit services covering code review, penetration testing, architecture analysis, and compliance validation. That includes application security audit for enterprise software where a breach is not just a technical problem but a business crisis. Ready for an application security audit quote?

Executive Summary

Application security audits typically cost between $5,000 and $50,000 depending on application complexity, testing scope, and compliance requirements. A focused web application penetration test takes 1 to 3 weeks. Comprehensive audits covering code review, architecture, and compliance take 4 to 8 weeks.

Core Capabilities and Features

Penetration Testing

Real-World Attack Simulation

Your application is tested against real-world attacks to find exploitable vulnerabilities. This includes testing against the OWASP Top 10 2025 (broken access control, security misconfiguration, software supply chain failures, cryptographic failures, injection, and more), business logic testing, authentication and session management testing, and API security testing. Every finding comes with a severity rating, proof of exploitability, and specific remediation guidance.

  • Testing against the OWASP Top 10 2025 including broken access control, security misconfiguration, and injection
  • Business logic testing, authentication and session management testing, and API security testing across web, mobile, and APIs
  • Every finding comes with a severity rating, proof of exploitability, and specific remediation guidance

Source Code Review

Security Weaknesses Hidden in Code

Your application source code is reviewed for security weaknesses that cannot be found through external testing alone. This includes hardcoded credentials, insecure cryptographic implementations, input validation gaps, SQL injection patterns, cross-site scripting vectors, and insecure deserialization. Automated static analysis (SAST) is combined with manual review by experienced security engineers who understand both the code and the attack patterns it is vulnerable to.

Architecture & Compliance Review

Systemic Security at the Design Level

Some vulnerabilities live in the design, not the code. Your application architecture is reviewed for systemic security issues: authentication flows, authorization models, data storage patterns, encryption implementation, session management, and trust boundaries. Your application is also assessed against relevant security standards and regulatory requirements: OWASP ASVS, PCI-DSS, HIPAA, GDPR, SOC 2, and ISO 27001. You receive a compliance gap analysis with specific actions needed to meet each requirement.

  • Review of authentication flows, authorization models, data storage patterns, encryption, and trust boundaries
  • Assessment against OWASP ASVS, PCI-DSS, HIPAA, GDPR, SOC 2, and ISO 27001

The Real Impact

Why It Matters

If you are about to close an enterprise deal that requires SOC 2 compliance, preparing for a funding round where due diligence will include a security review, or handling customer data that you cannot afford to lose, application security is not a technical nice-to-have. It is a business requirement. A single breach does not just cost money (though $4.44 million is the global average). It costs trust. Enterprise customers will not sign if your security posture is weak. Investors ask about security during due diligence. And regulators are getting less patient with companies that treat security as an afterthought. The companies that handle security well are the ones that treat audits as a regular part of their development lifecycle, not a panic response to a client asking 'have you been pen tested?' Build security in from the start, test it regularly, and fix what you find. That is the entire playbook.

Industry Data

By the Numbers

$4.44M

Global average cost of a data breach in 2025. In the United States, that number climbs to $10.22 million. The financial case for proactive security testing is straightforward.

68%

Of breaches involve a human element: phishing, credential theft, misconfigurations, or errors. Automated scanners do not catch most of these. Manual security testing does.

30%

Of all breaches now involve third-party or supply chain compromises, doubling from 15% in 2024. Your application is only as secure as the libraries and services it depends on.

241 days

Average time to identify and contain a breach in 2025, a nine-year low. Organisations with proactive security testing identify breaches faster and at lower cost.

3.73%

Of applications tested have broken access control vulnerabilities, the number one risk in the OWASP Top 10 2025. This is the most common and most dangerous category of application vulnerability.

"The audit report is not the deliverable. The deliverable is a more secure application. That is why we do not just hand over findings and walk away. We sit with your developers, explain the vulnerabilities, show them how to fix each one, and then retest to confirm the fixes work. That is what a real security audit looks like."

Our Process

How we turn ideas into reality.

01

Scoping

The testing scope is defined: which applications, APIs, and environments are in scope. Testing methodology, rules of engagement, and timeline are agreed upon. This takes 2 to 3 days.

02

Reconnaissance

The application attack surface is mapped: endpoints, authentication mechanisms, user roles, data flows, and third-party integrations. Areas of highest risk are identified and testing is prioritised accordingly.

03

Testing

Automated scans and manual testing are executed. Penetration testing, code review, and architecture analysis run in parallel. Every potential vulnerability is verified manually to eliminate false positives.

04

Reporting & Remediation

You receive a detailed report with every finding classified by severity (critical, high, medium, low, informational). Each finding includes a description, proof of exploitability, business impact, and specific remediation steps with code examples where applicable. Your development team is walked through the findings, and after remediation, retesting confirms the vulnerabilities are resolved.

Pricing

Investment Overview

Application Complexity

A 5-page marketing website costs far less to audit than a multi-tenant SaaS platform with 200 API endpoints, role-based access control, and payment processing. More functionality means more attack surface to test.

Contact us for a detailed project estimation.

Testing Scope

A penetration test alone is cheaper than a full audit covering pen testing plus code review plus architecture review plus compliance assessment. Most clients start with penetration testing and expand scope based on findings.

Contact us for a detailed project estimation.

Compliance Requirements

If you need to meet PCI-DSS, HIPAA, SOC 2, or GDPR requirements, the audit must cover specific controls and produce documentation that satisfies auditors. This adds time and cost.

Frequently Asked Questions

Everything you need to know about this service.

What is an application security audit?
An application security audit is a systematic assessment of a software application to identify security vulnerabilities, design flaws, and compliance gaps. It typically includes penetration testing (simulating real attacks), source code review, architecture analysis, and compliance evaluation against standards like OWASP ASVS, PCI-DSS, or SOC 2. The goal is to find and fix security weaknesses before they are exploited.
How often should we conduct security audits?
At minimum, annually. Ideally, after every major release or significant change to your application. If you handle sensitive data (financial, healthcare, personal), quarterly or continuous testing is recommended. The threat landscape evolves constantly, and your application changes with every deployment. Testing once and assuming you are secure is a common and costly mistake.
What is the difference between a vulnerability scan and a penetration test?
A vulnerability scan is an automated tool that checks your application against a database of known vulnerabilities. A penetration test is conducted by a human security professional who actively tries to exploit vulnerabilities, chain findings together, and test business logic flaws that scanners cannot detect. Scans find the obvious issues. Penetration tests find the dangerous ones.
How long does an application security audit take?
A focused penetration test on a web application takes 1 to 3 weeks. A comprehensive audit including code review, architecture analysis, and compliance assessment takes 4 to 8 weeks. The timeline depends on application complexity, the number of endpoints, and how many user roles need to be tested.
What do we receive at the end of the audit?
A detailed report with every finding classified by severity (critical, high, medium, low, informational). Each finding includes a technical description, proof of exploitability (screenshots, request/response data), business impact assessment, and specific remediation guidance with code examples where applicable. You also receive an executive summary for non-technical stakeholders.
Do you test in production or staging environments?
Testing can happen in either environment. Staging environments are preferred for destructive testing (testing that might cause data corruption or service disruption). Production testing is possible with careful scoping and non-destructive techniques. The environment, testing windows, and rules of engagement are agreed upon before any testing begins.
