Core Sentinel: Australia’s Premier Web Application Penetration Testing for SMEs

In the digital age, web applications power small to medium enterprises (SMEs) across Australia, from online stores to customer portals. But with cyber threats on the rise, securing these applications is critical. At Core Sentinel, we deliver web application penetration testing tailored for SMEs, ensuring your business stays safe. With thousands of tests completed and a team of Australia’s most qualified experts, we’re the trusted choice for penetration testing in Australia.

Why SMEs Need Web Application Penetration Testing

Cyberattacks target businesses of all sizes, and SMEs are often at higher risk due to limited cybersecurity resources. A single vulnerability in your web application—such as SQL injection, cross-site scripting (XSS), or misconfigurations—can lead to data breaches, financial loss, or reputational damage. Web application penetration testing simulates real-world attacks to uncover and fix these weaknesses before hackers exploit them.

At Core Sentinel, we specialize in SME-focused penetration testing. Unlike solutions designed for large corporations, our services are affordable, practical, and built to protect small to medium businesses without overwhelming your budget or team.

What Makes Core Sentinel the Best Choice for SMEs?

With over 20 years of international experience and a founder, Steve McLaughlin, who’s worked with global leaders like Aggreko UK and Wesfarmers Insurance, Core Sentinel brings enterprise-grade expertise to the SME market. Here’s why we stand out:

Unrivaled Expertise in Web Application Penetration Testing

Having conducted thousands of penetration tests, Core Sentinel has developed a world-class methodology based on industry standards like OWASP and NIST, enhanced by our proprietary techniques. Our team holds OSCE, OSCP, and CREST certifications, ensuring the highest level of technical skill. We focus specifically on web application penetration testing, making us the ideal partner for SMEs securing existing platforms or launching new ones.

Our clear, actionable reports prioritize vulnerabilities and provide step-by-step remediation guidance, empowering your team to act quickly and effectively.

Tailored for Small to Medium Enterprises

We understand that SMEs need cost-effective security solutions that don’t compromise on quality. Our flexible testing packages are designed to fit your budget, focusing on the most critical vulnerabilities to maximize value. Whether you’re a startup or an established business, we deliver penetration testing in Australia that’s accessible and impactful.

After testing, we offer manual re-testing to confirm that fixes are effective, giving you confidence in your application’s security.

Broad Industry Experience

Core Sentinel has secured web applications for hundreds of SMEs across diverse sectors, including retail, healthcare, finance, education, and technology. This experience equips us to address the unique security challenges your industry faces. Whether you’re launching an e-commerce platform or upgrading a customer portal, we’ve got you covered.

Our work also helps SMEs meet compliance standards like PCI DSS or ISO 27001, ensuring your business stays secure and compliant.

Comprehensive, Human-Driven Approach

While automated tools are useful, they often miss complex vulnerabilities like business logic flaws or privilege escalation issues. Core Sentinel combines advanced automation with meticulous manual testing, simulating real-world hacker techniques to uncover every weakness. Our proprietary scripts and expert audits ensure your web applications are thoroughly protected.

Exceptional Client Support

We’re more than a service provider—we’re your cybersecurity partner. From initial consultation to post-test support, our team is dedicated to your success. We provide comprehensive reports, made specifically to track testing progress and easy-to-understand reports that non-technical stakeholders can act on. Our clients value our responsiveness and commitment to their security.

Securing New Web Application Deployments

Launching a new web application is a pivotal moment for any SME, but it’s also when security matters most. A single flaw can expose your business to attacks before you gain momentum. Core Sentinel specializes in pre-launch penetration testing to ensure your application is secure from day one. We test for:

• Injection vulnerabilities (e.g., SQL injection, command injection)
• Cross-site scripting (XSS) and cross-site request forgery (CSRF)
• Authentication and authorization issues
• API and backend security flaws
• Cloud or hosting misconfigurations

Our OWASP- and NIST-aligned methodology ensures your application meets industry best practices, giving you a secure foundation for growth.

Our proven track record speaks for itself. With thousands of tests and a client base spanning multiple industries, we’ve earned a reputation as Australia’s go-to SME cybersecurity partner. Here’s what one client shared:
