Introduction

Web applications are the backbone of modern businesses in Brunei, powering e-commerce platforms, fintech solutions, healthcare systems, SaaS products, and government digital services. As Brunei continues to lead Southeast Asia in digital innovation and cloud adoption, the web application attack surface has expanded significantly.

Threat actors increasingly target vulnerabilities such as SQL Injection, Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), insecure authentication, misconfigured access controls, and exposed API endpoints. These weaknesses can lead to data breaches, regulatory penalties, financial losses, and reputational damage.

Cyberintelsys, a CREST-accredited cybersecurity firm, provides comprehensive Web Application Pentesting Services to help Brunei organizations identify, validate, and remediate security risks while aligning with PDPA, ISO 27001, GDPR, HIPAA, and PCI DSS.

Industry Challenges in Brunei

1. Rapid Digital Transformation: Organizations increasingly rely on web and cloud-based applications, expanding exposure to cyber threats.

2. Sophisticated Threat Actors: Automated attacks, AI-assisted exploitation, and zero-day vulnerabilities are becoming more common.

3. Regulatory Compliance Requirements: Businesses must comply with Brunei PDPA and international standards such as ISO 27001 and GDPR.

4. API & Third-Party Integrations: Extensive use of APIs, plugins, and SaaS components introduces hidden security risks.

5. Limited In-House Security Expertise: Many organizations lack specialized application security testing capabilities.
