Introduction
Jawa Timur (East Java) is one of Indonesia’s largest economic powerhouses, supporting manufacturing, logistics, financial services, healthcare, telecommunications, technology, education, government operations, and digital commerce. The province continues to demonstrate strong economic growth driven by industrial expansion, infrastructure development, investment, and increasing digital transformation initiatives.
As organisations across Jawa Timur continue adopting cloud computing, enterprise applications, APIs, remote work technologies, and connected digital ecosystems, cybersecurity risks continue to increase. Cybercriminals actively target vulnerabilities within networks, applications, cloud environments, and business systems through ransomware attacks, phishing campaigns, credential theft, insider threats, web application exploits, and advanced persistent threats (APTs).
CREST Certified Penetration Testing provides organisations with a proven method for identifying exploitable vulnerabilities before attackers can take advantage of them. By simulating realistic attack scenarios, penetration testing validates security controls, uncovers hidden security weaknesses, and helps organisations strengthen cyber resilience.
Cyberintelsys delivers CREST Certified Penetration Testing Services for organisations throughout Jawa Timur. Our experienced penetration testers assess enterprise infrastructure, cloud environments, web applications, APIs, mobile applications, and critical business systems to identify security gaps and reduce cyber risk.
Security Standards and Regulatory Alignment
Effective penetration testing requires a structured methodology aligned with internationally recognised cybersecurity standards and frameworks.
Cyberintelsys performs penetration testing aligned with:
ISO/IEC 27001 Information Security Management System (ISMS)
NIST SP 800-115 Technical Guide to Information Security Testing
OWASP Web Security Testing Guide (WSTG)
OWASP Application Security Verification Standard (ASVS)
PTES (Penetration Testing Execution Standard)
CIS Critical Security Controls
PCI DSS Penetration Testing Requirements
GDPR Security Principles
Cloud Security Best Practices for AWS, Microsoft Azure, and Google Cloud Platform
CREST accreditation is internationally recognised as a benchmark for quality penetration testing, ensuring assessments are performed using rigorous methodologies and highly skilled cybersecurity professionals.
Importance of CREST Certified Penetration Testing
Modern enterprise environments consist of interconnected technologies that significantly expand the attack surface available to threat actors.
These environments commonly include:
Internal and external networks
Cloud infrastructure
Web applications
APIs
Databases
Endpoints and servers
Remote access solutions
Third-party integrations
Regular penetration testing helps organisations:
Identify exploitable vulnerabilities before attackers do
Validate security controls and monitoring capabilities
Assess internal and external attack surfaces
Evaluate web application and API security
Detect authentication and authorisation weaknesses
Identify privilege escalation opportunities
Assess cloud security posture
Reduce exposure to ransomware and cyberattacks
Strengthen regulatory compliance readiness
Improve business continuity and resilience
Protect sensitive business information
Increase customer and stakeholder confidence
A proactive penetration testing programme provides visibility into real-world security risks and enables organisations to prioritise remediation based on actual business impact.
Our Methodology
Cyberintelsys follows a structured and risk-based penetration testing methodology combining automated assessment tools with expert manual testing.
1. Scope Definition
The engagement begins by identifying:
Critical business systems
Internal and external infrastructure
Cloud environments
Applications and APIs
Endpoints and servers
Network devices
Compliance requirements
Business objectives
This ensures testing focuses on systems that present the highest organisational risk.
2. Information Gathering and Reconnaissance
Security consultants analyse:
Domains and subdomains
Public-facing assets
Technology stacks
Operating systems
Cloud resources
Existing security controls
Third-party integrations
This phase establishes a comprehensive understanding of the organisation’s attack surface.
3. Vulnerability Identification
Advanced testing tools and manual validation identify:
SQL Injection vulnerabilities
Cross-Site Scripting (XSS)
Cross-Site Request Forgery (CSRF)
Authentication weaknesses
Authorisation flaws
Remote Code Execution (RCE)
Security misconfigurations
Weak encryption
API vulnerabilities
Cloud security weaknesses
All findings are manually validated to ensure accuracy and eliminate false positives.
4. Controlled Exploitation
Validated vulnerabilities are safely exploited to determine:
Real-world exploitability
Unauthorised access opportunities
Privilege escalation risks
Lateral movement capabilities
Sensitive data exposure
Potential business impact
Testing accurately simulates attacker behaviour while maintaining operational safety.
5. Risk Assessment
Each finding is evaluated according to:
Technical severity
Business impact
Asset criticality
Likelihood of exploitation
Existing security controls
Remediation complexity
This enables efficient prioritisation of remediation efforts.
6. Reporting and Remediation Guidance
The final report includes:
Executive summary
Technical findings
Risk ratings
Evidence and screenshots
Proof-of-concept validation
Remediation recommendations
Security improvement roadmap
Retesting services are available to verify remediation effectiveness after corrective actions have been completed.
